A marriage license and ceremony are the only way to be legally married in Nevada.
Nevada will recognize a valid common law marriage established in another state.
In Nevada, a marriage only exists when a couple obtains a marriage license and participates in a ceremony performed by an authorized officiant. Cohabitation alone never creates a marriage under Nevada law.
No. Nevada does not have common law marriage. The state abolished it in 1943, and no amount of time living together, sharing finances, or calling each other husband and wife creates a legal marriage under Nevada law. Without a marriage license and a ceremony performed by an authorized officiant, you are not married.
But what happens when a long-term unmarried relationship ends — especially when the couple owns property, shares debt, or has children — is more complicated than most people realize. Below, we explain what Nevada law says about common law marriage, the legal doctrines that can still protect unmarried partners, and what options are available to couples in Las Vegas and throughout Clark County.
Why Doesn’t Nevada Recognize Common Law Marriage?
Nevada formally abolished common law marriage on March 29, 1943. Under NRS 122.010 and NRS 122.020, the only way to be legally married in Nevada is to obtain a marriage license from a county clerk and have a ceremony performed by an authorized officiant.
It does not matter if you and your partner have lived together for decades, share a bank account, own a home together, file taxes jointly, wear wedding rings, use the same last name, or tell everyone you are married. Without a license and ceremony, Nevada considers you an unmarried couple — and that distinction affects property rights, support obligations, inheritance, and which court hears your case.
What Is Common Law Marriage?
Common law marriage is a legal concept recognized in some states where a couple is treated as legally married without ever obtaining a marriage license or having a formal ceremony. Requirements vary by state but typically include cohabitation, mutual agreement to be married, and publicly presenting as spouses. As of 2026, only a handful of states still allow new common law marriages. Nevada is not among them and has not been since 1943.
Does Nevada Recognize a Common Law Marriage From Another State?
Yes. Nevada does not allow common law marriage to be created here, but it will recognize one validly established in another state. This is based on the Full Faith and Credit Clause of the U.S. Constitution.
For example, if a couple established a valid common law marriage in Colorado or Texas and then relocated to Las Vegas, Nevada courts would recognize that marriage. The couple would have the same legal rights as any formally married couple, including community property protections under NRS 125.150, spousal support eligibility, and the ability to file for divorce in Clark County Family Court.
Proving a common law marriage from another state requires evidence that you met the originating state’s requirements while living there — joint tax returns, shared financial accounts, testimony from friends and family, and documentation showing you held yourselves out as married. A Las Vegas divorce attorney experienced with interstate marriage issues can help you build that case.
Married vs. Unmarried: How Nevada Law Treats You Differently
| Legal Right | Married / Domestic Partner | Unmarried (Cohabitating) |
|---|---|---|
| Community Property Division | Automatic — NRS 125.150 | Not automatic — requires contract or implied agreement |
| Alimony / Spousal Support | Yes — NRS 125.150 | No (unless putative spouse with fraud) |
| Child Custody | Yes — NRS 125C.003 | Yes — but paternity must be established first |
| Child Support | Yes — NRS 125B.070 | Yes — but paternity must be established first |
| Inheritance (No Will) | Yes — intestate succession | No — unmarried partner has no automatic inheritance rights |
| Court Jurisdiction | Family Court | Civil Court (contract law) |
What Is the Putative Spouse Doctrine in Nevada?
Even without common law marriage in Nevada, courts can protect a partner who genuinely believed they were legally married through the putative spouse doctrine. To qualify, two conditions must be met: the couple participated in a marriage ceremony, and one or both parties believed in good faith that no impediment prevented the marriage from being valid (Williams v. Williams, 97 P.3d 1124, Nev. 2004).
Common impediments include a prior undissolved marriage, a defective license, or an unauthorized officiant. If the court finds a putative marriage existed, community property law controls asset division — the same as a standard divorce. One limitation: putative spouse status does not automatically entitle a partner to spousal support absent a showing of fraud.
What Happens When Unmarried Couples Separate in Nevada?
Because there is no common law marriage in Nevada, a breakup between unmarried partners is not a divorce. Community property division under NRS 125.150, spousal support, and family court jurisdiction do not apply automatically.
However, the Nevada Supreme Court established a critical precedent in Hay v. Hay (100 Nev. 196, 1984). The court held that even without a legal marriage, it is not fair to allow one partner to take all jointly acquired property simply because the couple never formally married. The court applied quantum meruit and ruled that community property laws could be applied “by analogy” when partners can demonstrate an implied agreement to pool resources and share property — through joint bank accounts, shared mortgage payments, combined business income, or other documentation.
What Are the Alternatives to Marriage in Nevada?
Domestic Partnerships. Under NRS 122A, registered domestic partners have the same rights, protections, and obligations as married spouses — including community property, spousal support eligibility, and medical decision-making authority. Termination follows a process similar to divorce through family court.
Cohabitation Agreements. Unmarried couples can enter a written agreement defining how property, finances, and obligations are handled during the relationship and upon separation. These are enforceable as contracts in civil court. Since Hay v. Hay (1984), Nevada courts have recognized both express and implied contracts between cohabiting partners.
What About Children of Unmarried Parents?
Child custody and child support rights exist regardless of whether the parents were married. However, for unmarried fathers, paternity must be legally established first — voluntarily through a Declaration of Paternity (NRS 126.053) or by court order with genetic testing.
Once paternity is established, the same statutes apply as in a divorce. Custody follows the best interest of the child standard (NRS 125C.003), and support is calculated using Nevada’s statutory formula (NRS 125B.070).
Frequently Asked Questions
How long do you have to live together in Nevada to have a common law marriage?
No length of time creates a common law marriage in Nevada. You could live together for 1 year or 50 years — without a marriage license and ceremony, you are not legally married. Nevada abolished common law marriage in 1943.
Can I file for divorce in Nevada if I was never legally married?
No. Without a legal marriage or valid out-of-state common law marriage, you cannot file for divorce. Property disputes between unmarried partners go to civil court under contract law — not family court. The exception is if you qualify under the putative spouse doctrine.
Can my boyfriend or girlfriend take half my house in Nevada?
Not automatically. Because Nevada does not have common law marriage, an unmarried partner has no automatic right to your property. However, if your partner can show you had an agreement — written or implied — to share ownership, a court may apply community property rules by analogy under the Hay v. Hay precedent. Factors that matter include whose name is on the title, whether both partners contributed to mortgage payments, and whether you commingled finances.
Can an unmarried partner get alimony in Nevada?
Generally, no. Spousal support under NRS 125.150 is only available to legally married spouses or domestic partners. Unmarried partners may have a property claim under the Hay v. Hay framework, but not alimony unless the putative spouse doctrine applies and fraud is proven.
Is a domestic partnership the same as common law marriage in Nevada?
No. A domestic partnership requires formal registration with the Nevada Secretary of State under NRS 122A. Common law marriage — which Nevada does not recognize — would arise informally from cohabitation and mutual agreement without any registration or ceremony.
What happens to shared property if we break up and were never married?
Property is not automatically divided equally. Division depends on title, written agreements, and whether an implied contract to share property can be proven. Under Hay v. Hay, Nevada courts can apply community property principles by analogy when partners demonstrate they intended to pool resources.
Does Nevada recognize domestic partnerships from other states?
Yes. Under NRS 122A.500, Nevada recognizes substantially similar legal relationships from other jurisdictions — domestic partnerships, civil unions, and reciprocal beneficiary relationships all qualify.
What states still recognize common law marriage?
Several states still allow new common law marriages, including Colorado, Texas, Iowa, Kansas, Montana, Oklahoma, Rhode Island, and Utah. Nevada has not recognized common law marriage since 1943.
I got married in Las Vegas but it might not be valid. What are my rights?
You may be protected under Nevada’s putative spouse doctrine if you entered the ceremony in good faith and did not know a legal impediment existed. Courts can apply marital property laws to your situation even though the marriage itself is void.
