Benefits and Limitations of a Nevada Prenuptial Agreement

Benefits of a Nevada prenup

• Protects premarital assets from becoming community property through commingling during the marriage
• Keeps a business owned before marriage out of community property division under NRS 125.150
• Defines spousal support in advance instead of leaving it to Nevada court discretion under NRS 125.150(1)(a)
• Protects inheritance and family wealth intended for children from a prior relationship
• Prevents one spouse from being responsible for the other’s premarital debts
• Coordinates with estate planning through NRS 123A.050(1)(e), which allows prenups to require the making of a will or trust
• Reduces the cost and duration of a future divorce by resolving major financial issues in advance

Limitations of a Nevada prenup

• Cannot waive or reduce child support — the right belongs to the child under NRS 123A.050(2)
• Cannot predetermine child custody — the best-interest-of-the-child standard applies at the time of divorce
• Cannot include terms that violate public policy or a criminal statute under NRS 123A.050(1)(h)
• Cannot leave one spouse eligible for public assistance through an alimony waiver (NRS 123A.080(2))
• Can be invalidated for involuntary execution, unconscionability, or inadequate financial disclosure (NRS 123A.080)

What Is a Prenuptial Agreement Under Nevada Law?

A prenuptial agreement — also called a premarital agreement — is a written contract signed by both parties before marriage. Under NRS 123A.030, a “premarital agreement” is defined as an agreement between prospective spouses made in contemplation of marriage and to be effective upon marriage.

Nevada adopted the Uniform Premarital Agreement Act in 1989. The Act, codified at Chapter 123A of the Nevada Revised Statutes, provides a standardized legal framework for creating and enforcing prenups. Nevada courts follow clear statutory rules about what a prenup can include, how it must be executed, and when it can be challenged.

Under NRS 123A.040, a Nevada premarital agreement must be in writing and signed by both parties. It is enforceable without separate consideration — the marriage itself serves that function. Under NRS 123A.060, the agreement becomes effective only upon marriage.

A prenup is not a prediction that the marriage will end. It is a financial planning tool — particularly important in Nevada, a community property state where the default rules under Nevada community property law and NRS 123.220 assign equal ownership of most marital assets to both spouses regardless of whose name is on the title. For high net worth individuals, business owners, and those with premarital property, a prenup replaces those default rules with terms the parties choose themselves.

What Can a Prenuptial Agreement Cover in Nevada?

Under NRS 123A.050(1), parties to a Nevada premarital agreement may contract with respect to:

• Property rights (NRS 123A.050(1)(a)). The rights and obligations of each party in any property of either or both of them, whenever and wherever acquired or located.
• Property management (NRS 123A.050(1)(b)). The right to buy, sell, transfer, lease, encumber, or otherwise manage and control property during the marriage.
• Division on separation, divorce, or death (NRS 123A.050(1)(c)). How property will be disposed of upon separation, marital dissolution, death, or any other specified event.
• Spousal support (NRS 123A.050(1)(d)). The modification or elimination of alimony, spousal support, or maintenance. See our spousal support lawyer Las Vegas page for how Nevada courts handle alimony when no prenup exists, and our Nevada alimony calculator to model potential exposure before drafting these terms.
• Wills and trusts (NRS 123A.050(1)(e)). Requirements for the making of a will, trust, or other arrangement to carry out the provisions of the agreement. This is the statutory basis for coordinating a prenup with an estate plan.
• Life insurance (NRS 123A.050(1)(f)). Ownership rights and the disposition of death benefits from life insurance policies.
• Choice of law (NRS 123A.050(1)(g)). Which state’s law will govern the construction of the agreement — important if the parties later move out of Nevada.
• Any other lawful matter (NRS 123A.050(1)(h)). Any other matter, including personal rights and obligations, not in violation of public policy or a statute imposing a criminal penalty.

Most well-drafted Nevada prenups also address business interests (through the separate-property provisions in subsection (a)), retirement accounts, debt allocation, and the treatment of gifts and inheritance. For business owners, prenup provisions addressing existing ownership and post-marriage appreciation are among the most valuable clauses in the agreement.

What Cannot Be Included in a Nevada Prenup?

Nevada law places firm limits on what a prenuptial agreement can address:

• Child support cannot be adversely affected. Under NRS 123A.050(2), the right of a child to receive support may not be adversely affected by a premarital agreement. Child support belongs to the child, not the parents. Any contractual attempt to waive or reduce it is unenforceable.
• Child custody cannot be predetermined. Nevada courts always decide custody based on the best interest of the child at the time of divorce. A prenup cannot bind a judge’s future custody determination. See our child custody lawyer Las Vegas page for how Nevada courts make custody determinations.
• Terms that violate public policy or criminal statutes. NRS 123A.050(1)(h) permits contracting on any matter “not in violation of public policy or a statute imposing a criminal penalty.” Provisions incentivizing divorce, encouraging illegal conduct, or penalizing one spouse for exercising a legal right fall outside that boundary.
• Unconscionable terms. A court may refuse to enforce a prenup, or specific provisions within it, on grounds of unconscionability under NRS 123A.080(1)(b). Unconscionability can be substantive (the terms are grossly unfair) or procedural (the way the agreement was signed was grossly unfair).

A Nevada prenup is a powerful contract but it is not unlimited. Clauses that reach into prohibited territory can call the enforceability of the entire agreement into question.

Are Prenuptial Agreements Enforceable in Nevada?

Yes. Nevada courts enforce prenuptial agreements under NRS 123A.080. The statute establishes three grounds on which a premarital agreement is not enforceable if the party challenging it proves:

• Involuntary execution (NRS 123A.080(1)(a)). If one party was coerced, pressured, or otherwise did not execute the agreement voluntarily, the agreement is not enforceable. Last-minute signings under wedding-day pressure are the most common factual pattern raising this challenge.
• Unconscionability at execution (NRS 123A.080(1)(b)). The agreement is not enforceable if it was unconscionable when it was executed. Courts evaluate both substantive unconscionability (the terms themselves) and procedural unconscionability (how the agreement was signed).
• Inadequate financial disclosure (NRS 123A.080(1)(c)). The agreement is not enforceable if, before execution, the challenging party was not provided a fair and reasonable disclosure of the other party’s property and financial obligations, did not voluntarily and expressly waive that disclosure in writing, and did not otherwise have adequate knowledge of the other party’s finances.

Two statutory provisions within NRS 123A.080 deserve particular attention because they significantly shape how prenups are challenged and defended in Nevada courts.

Public Assistance Carveout — NRS 123A.080(2)

Under NRS 123A.080(2), if a provision of a premarital agreement modifies or eliminates alimony, spousal support, or maintenance of a spouse, and that modification or elimination causes one party to become eligible for support under a program of public assistance at the time of separation or marital dissolution, the court may require the other party to provide support to the extent necessary to avoid that eligibility — notwithstanding the terms of the agreement.

In practical terms: an otherwise-valid alimony waiver cannot leave one spouse on public assistance. The court retains equitable authority to override the waiver just enough to prevent that outcome. This is a narrow but real protection built into the statute itself.

Unconscionability Decided by the Court — NRS 123A.080(3)

Under NRS 123A.080(3), an issue of unconscionability of a premarital agreement shall be decided by the court as a matter of law. This means the judge — not a jury — makes the determination. In litigation over prenup enforcement, unconscionability is resolved through legal argument and documentary evidence presented to the court, not through a jury’s assessment of fairness.

What Strengthens Enforceability

All three enforceability grounds share a common theme: the agreement must be informed, voluntary, and not shockingly one-sided. To strengthen enforceability in Clark County Family Court:

• Independent counsel for each party. Nevada does not require it by statute but courts scrutinize prenups where one party was unrepresented, especially where the represented party drafted the agreement.
• Full financial disclosure. Attach financial schedules. Exchange tax returns. Document that disclosure was made. Any written waiver of disclosure must be voluntary and explicit.
• Adequate time for review. Sign the agreement well before the wedding. Thirty days is the absolute minimum; sixty to ninety days is substantially stronger.
• Balanced terms. Agreements that leave one spouse with essentially nothing after a long marriage are vulnerable to unconscionability challenges, even if the financial disclosure and voluntariness requirements were met.

How Nevada Courts Have Applied NRS 123A.080: Two Cases Every Couple Should Understand

NRS 123A.080 sets the statutory enforceability test for Nevada prenups, but the statute does not exist in a vacuum. Nevada Supreme Court decisions explain how courts evaluate voluntariness, unconscionability, and disclosure in practice. Two cases anchor the modern Nevada framework: Buettner v. Buettner (1973) established the common-law foundation, and Sogg v. Nevada State Bank (1992) established the procedural standards Nevada courts apply today.

Premarital agreements signed before October 1, 1989 are evaluated under the Buettner common-law framework or the requirements of NRS Chapter 123A, whichever the agreement satisfies. Agreements signed on or after that date are evaluated under NRS 123A, informed by the judicial interpretations in Sogg and the cases that followed it.

Buettner v. Buettner (1973): Nevada Prenups Are Not Void as Contrary to Public Policy

Citation: Buettner v. Buettner, 89 Nev. 39, 505 P.2d 600 (1973).

What happened: John and Stella Buettner signed an antenuptial agreement before their 1970 marriage. The agreement provided that on divorce, Stella would receive the marital residence and $30,000 paid over five years. John filed for divorce in April 1971 and asked the court to invalidate the prenup, arguing it was procured by fraud and was void as contrary to public policy because it contemplated divorce. The trial court agreed and invalidated the agreement, awarding Stella substantially less than the agreement provided. Stella appealed.

What the Nevada Supreme Court held: The court reversed the trial court’s public policy ruling. Premarital agreements addressing property settlement and support in the event of divorce are not automatically void as contrary to public policy in Nevada. The court held that premarital agreements are enforceable in Nevada unless they are “unconscionable, obtained through fraud, misrepresentation, material nondisclosure or duress.”

Why Buettner still matters in 2026: The four common-law invalidity grounds — unconscionability, fraud, misrepresentation, material nondisclosure, and duress — were later codified in modified form in NRS 123A.080. For pre-1989 agreements, Buettner remains the controlling standard. For post-1989 agreements, Buettner continues to inform how Nevada courts interpret the statutory unconscionability and disclosure requirements.

Sogg v. Nevada State Bank (1992): The Presumption of Fraud and the Fiduciary Relationship Between Fiancés

Citation: Sogg v. Nevada State Bank, 108 Nev. 308, 832 P.2d 781 (1992).

What happened: Paul Sogg was a wealthy real estate developer with a net worth of approximately $20 million. Victoria Sogg was a former country music singer with little independent financial resources. The day before their wedding, Paul took Victoria to his own attorney’s office to sign a premarital agreement she had never seen before. Paul’s attorney arranged for Victoria to meet with another attorney down the hall, but Paul interrupted that review session before it was complete. The wedding was cancelled when Victoria did not sign immediately. The parties reconciled weeks later and reset the wedding date. Victoria signed the agreement the day before the rescheduled wedding without ever fully reviewing it, on Paul’s promise that the agreement would be amended after the honeymoon to provide for her. The agreement was never amended. The trial court upheld the agreement; the Nevada Supreme Court reversed.

What the Nevada Supreme Court held: The court invalidated the premarital agreement. Three holdings from Sogg shape Nevada prenup law today:

1. Fiancés share a confidential, fiduciary relationship. Each party owes the other a duty of good faith and fair dealing in the premarital agreement process. This is a heightened duty above the standard applied to arms-length commercial contracts.
2. A presumption of fraud arises when the agreement greatly disfavors one party. When the terms of a premarital agreement substantially favor one party over the other, Nevada courts presume the agreement was procured through fraud. The burden then falls on the favored party to rebut that presumption with evidence of fair dealing, full disclosure, and voluntary execution.
3. Procedural defects can invalidate the agreement even where the disadvantaged party signed. The court identified specific procedural facts as dispositive: the husband’s attorney selected the wife’s reviewing attorney, the review session was interrupted by the husband, the wife’s attorney refused to certify that he had independently advised her, the wife never reviewed the complete agreement with independent counsel, and the wedding was cancelled when the wife did not sign immediately.

Why Sogg matters: Nevada courts continue to apply the Sogg framework when evaluating modern prenup challenges under NRS 123A.080. The case is most often cited for the presumption of fraud doctrine, the fiduciary relationship between fiancés, and the procedural requirements for independent counsel review by a qualified Nevada family law attorney. The State Bar of Nevada’s public guidance on prenuptial agreements reflects these same principles.

How Gastelum Attorneys Drafts to the Sogg Standard

Because Nevada courts continue to apply the Sogg framework, Jennifer Setters, J.D. and our Nevada family law team draft prenuptial agreements with the specific procedural protections the case identifies:

• Independent counsel verification. We never participate in selecting or arranging the other party’s reviewing attorney. If our client is the proposing party, the other party retains counsel of their own choosing through their own resources.
• Documented disclosure. Specific net worth statements, full asset schedules, and tax returns are exchanged and acknowledged in writing before execution. The agreement itself includes recitals confirming the disclosure.
• Timing discipline. We strongly recommend execution at least 30 to 60 days before the wedding. Our retainer agreements explicitly identify wedding-eve signings as a substantial enforceability risk.
• Substantive balance. Even when our client could obtain more favorable terms, we counsel against agreements that “greatly disfavor” the other party, because the Sogg presumption of fraud makes substantively one-sided agreements vulnerable to challenge.

Can a Prenup Be Overturned in Nevada?

A prenup can be overturned in Nevada if the challenging party proves one of the grounds listed in NRS 123A.080. The most common factual patterns Nevada courts see:

• One spouse did not disclose significant assets or debts before execution
• One spouse was given the agreement days or hours before the wedding with no meaningful opportunity to review it
• One spouse signed under duress, threat, or severe emotional pressure
• One spouse did not have and could not have had adequate knowledge of the other party’s finances
• The terms were so grossly one-sided as to be unconscionable at execution
• The alimony waiver would leave one spouse eligible for public assistance (NRS 123A.080(2) carveout)

The burden of proof falls on the party challenging the agreement. Nevada courts generally favor enforcing prenuptial agreements that were properly executed. Prenups signed with full financial disclosure, adequate review time, and independent legal advice for both parties are difficult to overturn.

If you are reviewing a proposed prenup drafted by your future spouse’s attorney — or if you believe an existing prenup may be challengeable — contact Gastelum Attorneys at (702) 979-1455 before signing or before initiating any proceeding.

When Should You Sign a Prenup Before the Wedding?

As early as possible. At the absolute minimum, 30 days before the wedding. Sixty to ninety days is substantially stronger.

The statutory enforceability test in NRS 123A.080 does not set a specific timing rule, but voluntariness is the first prong of the three-part test, and Nevada courts consistently treat last-minute signings as evidence of pressure. A prenup presented to a partner two days before the ceremony — when invitations are out, vendors are paid, and family has flown in — creates circumstances a judge can characterize as involuntary execution.

A workable timeline:

• Six or more months before the wedding: Begin the conversation. Identify the specific circumstances (business, inheritance, prior marriage, significant debt) that drive the need for a prenup.
• Four to six months before: Exchange financial disclosures. Each party retains separate counsel.
• Two to four months before: Draft, negotiate, revise. Attorneys communicate with each other; parties focus on terms, not line edits.
• Thirty or more days before: Sign the final agreement. Document the signing date, circumstances, and presence of counsel.

The timeline is not only a legal safeguard. A prenup signed calmly, months in advance, with real negotiation, is a fundamentally different document than one signed under pressure — even if the clauses look identical on paper.

---

What If Your Future Spouse Refuses to Sign a Prenup?

A prenuptial agreement requires both parties’ voluntary signatures under NRS 123A.040. If your future spouse refuses, you cannot compel them to sign — and attempting to do so would itself become evidence of involuntariness invalidating any signed agreement.

Practical options when one party will not sign:

• Postnuptial agreement after marriage. The conversation often becomes easier once the wedding is no longer imminent and the pressure of the timeline has lifted. See our postnuptial agreement Nevada page for how these agreements work and what they can cover.
• Pre-marital asset documentation. Even without a prenup, careful documentation of premarital assets — bank statements, deeds, appraisals, account balances on the wedding date — strengthens any future claim that those assets are separate property under NRS 123.130.
• Title strategy. Keeping premarital assets in individually titled accounts and avoiding commingling reduces the risk of those assets being characterized as community property during the marriage.
• Estate planning instruments. Trusts, beneficiary designations, and other estate planning tools can accomplish some of what a prenup does, though through different legal mechanics and with different protections.
• Mediated conversation. Many refusals stem from the way the prenup was raised, not the document itself. An attorney-mediated discussion with both parties — focused on shared financial goals rather than worst-case scenarios — can sometimes resolve the underlying concerns.

A refusal to sign a prenup is often less about the document and more about the conversation surrounding it. Address the conversation first, the document second.

How Much Does a Prenup Cost in Nevada?

In Nevada (2026), prenuptial agreement costs range from $1,500 to $10,000 or more per party, with each party retaining separate counsel. Average cost: approximately $3,000–$5,000 per party for moderate-complexity agreements.

Complexity	Typical Cost Per Party	Common Situations
Simple	$1,500–$3,000	Straightforward assets, no business interests, modest premarital property
Moderate	$3,000–$5,000	Real estate, retirement accounts, investment portfolios requiring schedules
High-asset or business	$5,000–$10,000+	Business ownership, business valuations, multiple properties, complex investments, second marriages with children

Each party should retain separate counsel, so total cost includes fees for both attorneys. The cost of a well-drafted prenup is a fraction of contested high net worth property division in a litigated divorce, which can exceed $50,000–$150,000 per side.

---

Do You Need a Prenup If Nevada Is a Community Property State?

Nevada is a community property state. Without a prenup, most assets and debts acquired during the marriage are owned equally by both spouses under NRS 123.220, with each spouse holding a present, existing, and equal interest under NRS 123.225. At divorce, NRS 125.150 directs the court to make an equal disposition of community property to the extent practicable, with unequal dispositions permitted only for compelling reasons stated in writing. See our full Nevada community property guide for details.

The statutory interlock between prenups and divorce. NRS 125.150 expressly defers to Chapter 123A prenuptial agreements. The statute begins: “Except as otherwise provided in NRS 125.155 and 125.165, and unless the action is contrary to a premarital agreement between the parties which is enforceable pursuant to chapter 123A of NRS…” This is the direct statutory link between prenup law and divorce outcome: a valid Chapter 123A prenup modifies what would otherwise be the default Chapter 125 divorce result.

Common reasons to use a prenup in Nevada:

• Protecting premarital assets. Without a prenup, premarital assets can become community property through commingling. A prenup keeps the classification clear and documented.
• Protecting a business. A business founded or grown during the marriage using marital funds or effort is community property absent a prenup.
• Defining spousal support in advance. Nevada courts have broad discretion in awarding alimony under NRS 125.150(1)(a). A prenup replaces that discretion with agreed-upon terms.
• Protecting inheritance rights. Ensures family wealth and inherited property pass to intended heirs rather than being subject to division.
• Second marriages. Protecting assets intended for children from a prior relationship — one of the most common prenup scenarios in Nevada.
• Debt protection. Preventing one spouse from being responsible for the other’s premarital or marital debts.

Nevada Prenuptial Agreement Law vs. Other States

Nevada’s Uniform Premarital Agreement Act (NRS 123A) is based on the model uniform act adopted by approximately half of U.S. states. Among states most relevant to Nevada residents:

• California (Family Code § 1615(c)(2)(B)). Imposes a mandatory 7-calendar-day waiting period between presentation of the final agreement and signing, for all prenups executed on or after January 1, 2020. The waiting period applies regardless of attorney representation and cannot be waived. Nevada has no equivalent statutory waiting period, though the voluntariness requirement under NRS 123A.080(1)(a) creates a similar protective effect through case-by-case judicial scrutiny.
• Other community property states. Nine U.S. states use community property as the default marital property regime: Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin. Each generally enforces prenups under uniform-act-derived frameworks, but specific procedural requirements vary by state.
• Choice of law. If your prenup was signed in another state and you have since moved to Nevada — or vice versa — NRS 123A.050(1)(g) allows the parties to specify which state’s law governs interpretation. Without a choice-of-law provision, courts typically apply the law of the state where the agreement was executed.

If you signed a prenup in California and have since relocated to Nevada, Nevada courts will generally honor the California-law enforceability analysis — including the 7-day waiting period if the agreement was executed on or after January 1, 2020. Conversely, a Nevada prenup carried into a state with stricter procedural requirements may face challenges its drafters did not anticipate. If you are relocating, an attorney review of your existing prenup against the destination state’s enforceability framework is worth the modest cost.

How to Get a Prenuptial Agreement in Nevada

1. Start early. Begin discussions and drafting at least 30 to 60 days before the ceremony. Agreements signed days before a wedding are the most vulnerable to claims of coercion — this is the most commonly cited basis for challenges in Nevada courts.
2. Full financial disclosure. Both parties fully disclose assets, income, debts, and financial obligations. Attach financial schedules listing all property and liabilities.
3. Draft the agreement. Work with a Nevada family law attorney experienced in NRS 123A. The agreement should clearly state each party’s rights and obligations in plain language, with property schedules attached as exhibits.
4. Independent legal review. Each party has the agreement reviewed by their own attorney. While not legally required, independent counsel for both parties is the single strongest enforceability protection available.
5. Sign voluntarily. Both parties sign in writing per NRS 123A.040. Neither party should feel rushed or pressured. Document that both parties had adequate time to review and consider the terms.
6. Store safely. Keep the original signed agreement in a secure location. Provide certified copies to both parties and their attorneys. Consider storing a copy with your estate planning documents given the coordination between the prenup and any will or trust.

---

Can a Nevada Prenup Be Changed or Revoked After Marriage?

Yes. Under NRS 123A.070, after marriage a premarital agreement may be amended or revoked only by a written agreement signed by both parties. The amended agreement or revocation is enforceable without separate consideration.

Both amendment and revocation require mutual consent, in writing, signed by both parties. A prenup cannot be modified unilaterally — if one spouse wants changes and the other refuses, the original agreement remains in force.

Couples who want flexibility often include a built-in review provision — for example, a clause stating the parties will review the agreement every five years, upon the birth of a child, or upon a specified change in income. The review clause does not amend the agreement automatically but creates a structured moment to discuss whether amendments are appropriate.

If no amendment is made, the original terms govern. Over long marriages, original terms can produce results neither party would agree to today — which is why thoughtful drafting at the outset, with reasonable flexibility built in, is worth the investment.

---

What Is the Time Limit for Challenging a Nevada Prenup?

Under NRS 123A.100, any statute of limitations applicable to an action asserting a claim for relief under a premarital agreement is tolled during the marriage of the parties to the agreement. The limitations clock does not run while the couple is married.

A spouse can challenge the agreement at the point of divorce, separation, or the death of the other spouse, even if the agreement was signed decades earlier. Equitable defenses — including laches and estoppel — remain available to either party. A spouse who accepts the benefits of a prenup for twenty years and then challenges it at divorce may find that equitable defenses limit the challenge even though the statute itself does not.

---

Do We Still Need a Will If We Have a Prenup?

Yes. A prenuptial agreement and a will serve related but distinct functions.

A prenup defines property rights between spouses — during marriage, at divorce, and at death. A will directs the disposition of a person’s estate at death, including property not covered by a prenup and property left to people other than the surviving spouse.

Under NRS 123A.050(1)(e), prenups may expressly require the making of a will, trust, or other arrangement to carry out the provisions of the agreement. Coordinating a prenup with an estate plan is standard practice. Leaving a prenup in place without a corresponding will can create ambiguities that surviving family members must litigate — which is often exactly what the prenup was meant to prevent.

What Is a Postnuptial Agreement in Nevada?

A postnuptial agreement is similar to a prenup but is signed after the marriage has already begun. Nevada recognizes postnuptial agreements under general contract law principles and the authority of married spouses to contract with each other.

Postnuptial agreements serve the same core purpose as prenups — defining property rights, debt responsibility, and spousal support — but they can also address circumstances that arose after marriage:

• One spouse starting or acquiring a business during the marriage
• Receiving a large inheritance that needs protection going forward
• Significant changes in income, wealth, or financial status
• Reconciliation after a period of separation
• A high net worth individual who did not execute a prenup and wants to protect assets mid-marriage

To be enforceable, a Nevada postnuptial agreement should be voluntary, supported by full financial disclosure, and not unconscionable. The same principles that protect prenup enforceability under NRS 123A apply by analogy. For our complete guide to Nevada postnuptial agreements, see our dedicated postnuptial agreement Nevada page.

Protecting Your Business with a Nevada Prenup

For business owners, a prenuptial agreement is one of the most effective tools available to keep a business out of community property division. Without a prenup, a business founded or grown during the marriage using marital funds or labor is community property under NRS 125.150 — subject to equal division regardless of whose name appears on the ownership documents.

A properly drafted prenup can:

• Designate the business as separate property
• Specify that growth during the marriage attributable to the owner’s personal effort remains separate
• Establish a buyout formula that limits the non-owner spouse’s claim in the event of divorce
• Address ownership of any spin-off or successor business
• Coordinate with business operating agreements and buy-sell provisions

This protection is significantly easier to establish in a prenup than to reconstruct during divorce.

---

Prenups and Hidden Assets — What You Need to Know

A prenuptial agreement is only as enforceable as the financial disclosure that supports it. If one party conceals assets during the prenup process — failing to disclose accounts, business interests, real estate holdings, or liabilities — the agreement is vulnerable to challenge under NRS 123A.080(1)(c) for inadequate disclosure.

Our attorneys verify financial disclosure completeness before advising any client to sign a proposed prenup. If you believe your future spouse has not fully disclosed their assets or debts, this is a significant red flag.

Frequently Asked Questions — Prenuptial Agreements in Nevada

Are prenuptial agreements enforceable in Nevada?

Yes. Nevada courts enforce prenuptial agreements under NRS 123A.080 as long as the agreement was signed voluntarily, was not unconscionable when executed, and was supported by fair and reasonable financial disclosure (or a voluntary written waiver of disclosure). The burden of proof falls on the party challenging the agreement.

What can a prenup cover in Nevada?

Under NRS 123A.050, a Nevada prenup can address property rights, property management, division at separation or death, spousal support, wills and trusts, life insurance, choice of law, and any other matter not in violation of public policy. A prenup cannot adversely affect a child’s right to support, and cannot predetermine child custody.

How far in advance should a prenup be signed in Nevada?

At least 30 to 60 days before the wedding, with 60 to 90 days preferred. Agreements signed days before a ceremony are most vulnerable to challenge on grounds of coercion or involuntariness under NRS 123A.080(1)(a). The more time between signing and the wedding, the stronger the evidence that both parties acted voluntarily.

Does a prenup need to be notarized in Nevada?

Nevada does not require notarization for a prenuptial agreement to be valid. Under NRS 123A.040, the agreement must be in writing and signed by both parties. Notarization and witness signatures are not statutory requirements but strengthen enforceability by providing additional evidence of voluntary execution.

Can my fiancé and I use the same lawyer for a Nevada prenup?

Legally, you can share one attorney — Nevada does not require independent counsel by statute. Practically, you should not. Nevada courts scrutinize prenups where one party was unrepresented, and independent counsel for each party is the single strongest enforceability factor under NRS 123A.080. Sharing one attorney also creates a conflict of interest if the prenup is ever challenged, since the same lawyer cannot represent both sides of an adverse negotiation.

Can a prenup protect my business in a Nevada divorce?

Yes. A prenup can designate a business as separate property, exclude business growth during the marriage from community property, and establish a buyout formula limiting the non-owner spouse’s claim. Without a prenup, a business founded or grown during the marriage is community property under NRS 125.150 subject to equal division.

Does a Nevada prenup protect inheritance?

Yes. A Nevada prenup can designate inheritances and family gifts as separate property regardless of when they are received. Without a prenup, inheritances can become community property through commingling or titling decisions during the marriage. Under NRS 123A.050(1)(e), a prenup can also require coordination with a will or trust to ensure inherited assets pass to intended heirs.

Can a prenup waive alimony in Nevada?

Yes, a prenup can address spousal support under NRS 123A.050(1)(d) — setting agreed amounts, duration, or a complete waiver. However, under NRS 123A.080(2), if an alimony waiver would cause one spouse to become eligible for public assistance at the time of separation or dissolution, the court may require the other party to provide support to the extent necessary to avoid that eligibility, notwithstanding the agreement.

Can you include cheating clauses in a Nevada prenup?

Infidelity clauses — sometimes called “bad behavior” or “morality” clauses — are generally not reliably enforceable in Nevada. Nevada is a no-fault divorce state, meaning the court does not consider marital fault when dividing property or awarding alimony. Clauses that try to penalize infidelity by shifting property or increasing support obligations risk being struck as violating public policy under NRS 123A.050(1)(h). Financial provisions tied to specific, objective events are more reliably enforceable than open-ended fault clauses.

How much does a prenup cost in Las Vegas?

A simple prenup typically costs $1,500–$3,000 per party. Moderate complexity (real estate, retirement accounts) runs $3,000–$5,000 per party. High-asset or business prenups cost $5,000–$10,000+ per party. Each party should retain their own attorney, so total cost covers both sides.

Who decides whether a prenup is unconscionable in Nevada?

Under NRS 123A.080(3), an issue of unconscionability of a premarital agreement shall be decided by the court as a matter of law. The judge — not a jury — makes the determination. Unconscionability is resolved through legal argument and documentary evidence presented to the court.

What happens to my Nevada prenup if we move out of state?

The enforceability of your Nevada prenup in another state depends on that state’s law and any choice-of-law provision in the agreement itself. NRS 123A.050(1)(g) allows parties to specify which state’s law governs the agreement, which becomes important if the couple later relocates. Most states enforce properly executed Nevada prenups under the Uniform Premarital Agreement Act or equivalent state statutes.

What if my future spouse refuses to sign a prenup?

You cannot compel a future spouse to sign a prenup — NRS 123A.040 requires both parties’ voluntary signatures, and any attempt to force a signature would itself invalidate the agreement on voluntariness grounds. Practical alternatives include a postnuptial agreement signed after the wedding, careful documentation of premarital assets to preserve their separate-property status under NRS 123.130, individual titling of premarital accounts to avoid commingling, and estate planning instruments such as trusts and beneficiary designations.

Can a Nevada prenup be changed after marriage?

Yes. Under NRS 123A.070, after marriage a premarital agreement may be amended or revoked only by a written agreement signed by both parties. The amendment or revocation is enforceable without consideration. A prenup cannot be changed unilaterally.

How long do I have to challenge a prenup in Nevada?

Under NRS 123A.100, any statute of limitations applicable to a claim under a prenup is tolled during the marriage. The clock does not run while the couple is married. Challenges can be raised at divorce, separation, or the death of the other spouse. Equitable defenses such as laches and estoppel remain available.

What is the difference between a prenup and a postnuptial agreement in Nevada?

A prenup is signed before marriage and is governed by Chapter 123A. A postnuptial agreement is signed during the marriage and is governed by general Nevada contract principles applicable to spouses. Both can define property rights, debt responsibility, and spousal support. See our Nevada postnuptial agreement page for details.

What Nevada cases govern prenup enforceability?

Two Nevada Supreme Court decisions anchor the modern framework. Buettner v. Buettner, 89 Nev. 39 (1973), established that Nevada prenups are not void as contrary to public policy and set the common-law invalidity grounds: unconscionability, fraud, misrepresentation, material nondisclosure, and duress. Sogg v. Nevada State Bank, 108 Nev. 308 (1992), established that fiancés share a confidential, fiduciary relationship and that a presumption of fraud arises where the agreement greatly disfavors one party. Nevada courts continue to apply these cases when evaluating prenup challenges under NRS 123A.080.

New Beginnings, Brighter Tomorrows. — Gastelum Attorneys

Pre-Nup Meaning at a Glance: What These Terms All Refer To

The same Nevada legal instrument goes by several casual and formal names. They all refer to the same agreement under NRS Chapter 123A:

• Prenup — the most common casual term used in everyday conversation
• Pre-nup or pre nup — the same word with a hyphen or a space; no legal distinction
• Prenuptial agreement — the standard plain-English legal term
• Premarital agreement — the exact statutory term used in NRS 123A.030
• Antenuptial agreement — an older common-law term still occasionally used in case law, including the Nevada Supreme Court’s 1973 decision in Buettner v. Buettner

Nevada courts and statutes treat these terms as fully interchangeable. The legal effect of the agreement comes from what it contains and how it was executed under NRS 123A, not from what the parties choose to call it.

What Does a Prenup Do? Functions and Protections in Nevada

A prenup does five things at once in Nevada: it replaces Nevada’s community property default rules, defines spousal support in advance, allocates premarital and marital debts, protects business and inheritance interests, and coordinates with estate planning. Each of these functions is authorized by the Uniform Premarital Agreement Act at NRS Chapter 123A, which permits couples to contract around the otherwise-mandatory community property and divorce rules in NRS 123.220 and NRS 125.150.

Put more simply: a Nevada prenup is the only legal instrument that lets a couple write their own rules for property, debt, and support before the wedding — replacing what the Nevada Legislature and Clark County Family Court would otherwise impose.

The Five Primary Functions of a Nevada Prenup

• Replaces Nevada’s community property defaults. Without a prenup, Nevada law treats most assets and debts acquired during the marriage as community property — owned equally by both spouses regardless of whose name is on the title. A Nevada prenup under NRS 123A.050(1)(a) lets the parties choose which property stays separate, which becomes community, and how each spouse manages and controls that property during the marriage.
• Defines spousal support in advance. Nevada courts have broad discretion to award alimony under NRS 125.150(1)(a) based on factors a judge weighs at the time of divorce. A prenup replaces that judicial discretion with terms the parties agree to themselves, including modification or elimination of spousal support under NRS 123A.050(1)(d) — subject to the public assistance carveout in NRS 123A.080(2) discussed elsewhere on this page.
• Allocates debt responsibility. Nevada is a community property state, which means debts incurred during the marriage are generally the responsibility of both spouses, regardless of which spouse signed for them. A Nevada prenup can specify that premarital debts stay with the spouse who incurred them and can allocate responsibility for future debts between the parties — a function especially valuable when one party brings significant debt into the marriage.
• Protects business and inheritance interests. A business founded before marriage, or an expected inheritance and family wealth, can be expressly classified as separate property in the prenup. Without a prenup, business appreciation during the marriage and the use of marital effort to grow the business can convert separate property into community property through commingling. For business owners, prenup provisions addressing existing ownership, post-marriage appreciation, and the treatment of business income are typically the highest-value clauses in the agreement.
• Coordinates with estate planning. NRS 123A.050(1)(e) expressly allows prenups to require the making of a will, trust, or other estate planning arrangement. For blended families and second marriages, this is often the central function of the agreement — ensuring that assets pass to children from a prior relationship even if the new spouse outlives the first parent.

What a Nevada Prenup Does Not Do

For all the functions a prenup does perform, Nevada law places three firm limits on what a prenup can accomplish:

• A Nevada prenup cannot adversely affect a child’s right to support. Child support belongs to the child under NRS 123A.050(2), not to the parents, and cannot be contracted away.
• A Nevada prenup cannot predetermine child custody. Custody is decided based on the best interest of the child at the time of divorce, applying the standards a judge in Clark County Family Court uses at that time.
• A Nevada prenup cannot include terms that violate public policy or a criminal statute under NRS 123A.050(1)(h). Provisions incentivizing divorce, encouraging illegal conduct, or penalizing a spouse for exercising a legal right fall outside what NRS 123A permits.

Can You Use a Prenuptial Agreement Template in Nevada?

Short answer: Technically yes, but a generic prenuptial agreement template is one of the most common reasons Nevada prenups are later overturned. NRS 123A.080 enforceability turns on procedural and substantive requirements that off-the-shelf templates almost never satisfy.

Why Generic Prenup Templates Fail in Nevada

A prenuptial agreement template you find online — whether a free downloadable PDF, a paid form-document service, or a state-bar generic form from another state — typically fails one or more of the following Nevada-specific requirements:

• Missing financial disclosure schedules. NRS 123A.080(1)(c) requires that, before execution, each party either receive fair and reasonable disclosure of the other’s property and financial obligations, or voluntarily and expressly waive that disclosure in writing. Generic templates rarely include the schedule attachments or the precise waiver language Nevada courts look for under Sogg v. Nevada State Bank.
• No public assistance carveout language. NRS 123A.080(2) authorizes Nevada courts to override an alimony waiver to the extent necessary to prevent one spouse from becoming eligible for public assistance at the time of divorce. Templates that include a flat alimony waiver without acknowledging this carveout can be partially invalidated — often unpredictably and at the worst possible moment, during divorce litigation.
• No procedural safeguards from Sogg v. Nevada State Bank. The 1992 Nevada Supreme Court decision in Sogg established that fiancés share a fiduciary relationship, that a presumption of fraud arises when an agreement greatly disfavors one party, and that procedural defects — even where both spouses signed — can invalidate the agreement. Generic templates do not document independent counsel review, uninterrupted negotiation time, or balanced terms. They assume the parties will handle process on their own, which is exactly where most challenges succeed.
• No Nevada community property context. Most prenup templates available online are written for common-law-property states and do not address how the agreement modifies Nevada’s NRS 123.220 community property default. A Nevada-compliant prenup must affirmatively classify each asset and debt against the community property baseline — a step that does not exist in the legal frameworks of 41 other states.
• Generic choice-of-law clauses. Templates often default to “the law of the state where the agreement is signed” or to no choice-of-law provision at all — which can cause unpredictable results if the parties later relocate. NRS 123A.050(1)(g) allows the parties to specify Nevada law (or another state’s law) explicitly. The absence of an affirmative Nevada choice-of-law clause is a common drafting failure in template-derived agreements.
• No execution-timing safeguards. Voluntariness under NRS 123A.080(1)(a) is the first prong of the enforceability test, and wedding-eve signings are the most common factual basis for successful challenges. Templates do not document execution timing or build in the procedural buffer that strengthens voluntariness — a deficiency that becomes critical if the agreement is challenged years later.

What a Nevada-Compliant Prenuptial Agreement Template Should Include

A properly drafted Nevada prenuptial agreement, at minimum, contains:

• Recitals identifying both parties, the upcoming marriage, and the date and location of execution
• Representations that each party has had the opportunity to consult independent counsel
• Full financial disclosure schedules attached as exhibits, including specific asset and liability values
• Explicit voluntary written waivers of any disclosure obligations the parties choose not to satisfy
• An affirmative choice-of-law clause selecting Nevada under NRS 123A.050(1)(g)
• Statutory citation to NRS Chapter 123A and acknowledgment of its application
• Specific separate-property and community-property classifications for each significant asset
• Spousal support provisions that account for the NRS 123A.080(2) public assistance carveout
• Provisions addressing business interests, retirement accounts, life insurance, and inheritance
• Estate planning coordination language under NRS 123A.050(1)(e) where applicable
• Signature blocks with date, time, and location of execution
• Notarization or sworn witness attestation
• Counsel certifications that each party was independently advised

The Practical Recommendation

For Nevada residents drafting a prenup before marriage, a template is at best a structural reference for what topics to discuss with counsel. The actual document requires Nevada-specific drafting, full financial disclosure documentation, and independent counsel review on both sides. The cost of attorney-drafted prenup work — typically $1,500 to $10,000 per party as discussed in the cost section above — is a small fraction of contested asset division in a litigated divorce, which can exceed $50,000 to $150,000 per side once a template-based agreement is successfully challenged.

If you have already signed a prenup based on a template and want to know whether it is enforceable under NRS 123A.080 and the Sogg framework, call (702) 979-1455 to schedule an independent review with a Las Vegas prenup lawyer. If you are about to be presented with a template-based prenup by your future spouse’s attorney, get independent review before signing — not after.

What does a prenup do?

A prenup replaces the default community property and divorce rules that would otherwise apply under Nevada law. It defines how property, debts, and spousal support are handled during the marriage and at divorce, protects premarital assets and business interests, allocates debt responsibility between the parties, and coordinates with estate planning. Under NRS Chapter 123A, a Nevada prenup cannot adversely affect a child’s right to support or predetermine child custody.

What does “prenup” or “pre-nup” mean?

“Prenup” — also spelled pre-nup or pre nup — is the casual short form of “prenuptial agreement,” a written contract signed by both parties before marriage that governs property, debt, and spousal support if the marriage ends. Whether spelled with or without a hyphen, the term refers to the same legal instrument. Nevada’s statutory term is “premarital agreement,” defined at NRS 123A.030, and Nevada courts treat all these names as fully interchangeable.

Can I use a prenuptial agreement template in Nevada?

Generic prenuptial agreement templates are one of the most common reasons Nevada prenups are later overturned under NRS 123A.080. Most templates miss required Nevada-specific elements — financial disclosure schedules, public assistance carveout language, Sogg v. Nevada State Bank procedural safeguards, community-property classifications, and an affirmative Nevada choice-of-law clause. A template can serve as a structural reference for discussion, but the actual document requires Nevada-specific drafting and independent counsel review on both sides.
