Nevada does not allow couples to form a common law marriage within the state, no matter how long they live together or share a household. Nevada law has required a marriage license and a solemnization ceremony since March 29, 1943, and nothing substitutes for that process.1Nevada Legislature. Nevada Revised Statutes 122.010 – What Constitutes Marriage; No Common-Law Marriages After March 29, 1943 If you already established a common law marriage in a state that permits one and then moved to Nevada, the state will recognize it. Couples who want legal protection without a traditional wedding have another route: a registered domestic partnership, which carries nearly the same rights as marriage under Nevada law.
Why Nevada Doesn’t Allow New Common Law Marriages
Nevada statute is explicit: consent alone does not create a marriage. It must be followed by a ceremony authorized under state law.1Nevada Legislature. Nevada Revised Statutes 122.010 – What Constitutes Marriage; No Common-Law Marriages After March 29, 1943 Any common law marriage that existed before the 1943 cutoff was grandfathered in, but no new ones can arise within the state.2Nevada Legislature. Domestic Relations and Family Law
The practical effect is significant. You and your partner can live together for decades, share bank accounts, raise children, and introduce each other as spouses, and Nevada will still treat you as legally unmarried. Without a valid marriage or a registered domestic partnership, you have no automatic right to your partner’s property if the relationship ends, no spousal inheritance if your partner dies without a will, and no standing to seek spousal support.
When Nevada Recognizes a Common Law Marriage From Another State
Nevada will treat a common law marriage as valid if it was legally created in a state that allows them. This flows from the Full Faith and Credit Clause of the U.S. Constitution, which generally requires states to honor legal relationships formed elsewhere. If you established a common law marriage in another jurisdiction and later moved to Nevada, the state will recognize it for divorce, property division, inheritance, and other legal purposes.
Your relationship must have satisfied every element of common law marriage in the state where it began. Courts typically look for a mutual agreement to be married, cohabitation in that state, and public presentation as a married couple. Only a handful of jurisdictions still permit new common law marriages: Colorado, Iowa, Kansas, Montana, South Carolina, Texas, Utah, Rhode Island, Oklahoma, and the District of Columbia.3National Conference of State Legislatures. Common Law Marriage by State Each has its own requirements, so qualifying under one state’s rules does not mean you would qualify under another’s.
Federal Recognition After You Move to Nevada
If your common law marriage was valid where it was formed, the federal government generally continues to recognize it even after you relocate to Nevada. That matters for several practical areas of life.
Taxes
The IRS considers you married for the entire tax year if, on the last day of the year, you are living together in a common law marriage recognized either in the state where you now live or in the state where the marriage began.4Internal Revenue Service. Publication 501 (2025), Dependents, Standard Deduction, and Filing Information If your marriage qualifies, you may file jointly, and both spouses become jointly and individually responsible for any tax owed on that return.
Social Security
The Social Security Administration recognizes common law marriages formed in states that allow them, and a valid common law spouse can qualify for spousal and survivor benefits. The SSA asks for signed statements from both spouses (or the surviving spouse) along with statements from blood relatives of the other spouse.5eCFR. 20 CFR Part 404 Subpart H – Evidence of Common-Law Marriage When those are unavailable, other evidence such as joint bank accounts, shared mortgages, or beneficiary designations may be accepted.
Family and Medical Leave
The Family and Medical Leave Act defines “spouse” to include a husband or wife in a common law marriage recognized in the state where the marriage was entered into.6U.S. Department of Labor. Fact Sheet #28L – Leave Under the Family and Medical Leave Act Domestic partners and people in civil unions are not spouses under the FMLA and cannot take FMLA leave to care for each other.
Immigration
For visa petitions, the State Department treats a common law marriage as valid only if it was legally recognized where created and is fully equivalent to a traditional marriage. The relationship must be terminable only by divorce or death and must carry rights to alimony, intestate inheritance, and child custody, the same as a ceremonial marriage.7U.S. Department of State. Foreign Affairs Manual – Family-Based Relationships: Marital Relationship
Domestic Partnership: Nevada’s Alternative
For couples who want legal recognition without a traditional wedding, Nevada offers registered domestic partnerships that carry nearly the same weight as marriage under state law.
How to Register
Both partners must share a common residence, be at least 18 years old, be competent to consent, and not be related in a way that would prohibit marriage.8Nevada Legislature. Nevada Revised Statutes 122A.100 – Registration: Procedure; Fees; Eligibility; Issuance of Certificate You file a signed and notarized declaration with the Nevada Secretary of State and pay a $50 fee that includes the certificate.9Nevada Secretary of State. Domestic Partnerships
What Registration Gets You Under State Law
Once registered, domestic partners receive the same rights, protections, and benefits, and take on the same responsibilities, as married spouses under Nevada law.10Nevada Legislature. Nevada Revised Statutes 122A.200 – Rights and Duties of Domestic Partners These include:
- Community property treatment of assets and debts acquired during the partnership.
- The right of either partner to seek financial support if the partnership dissolves.
- Intestate inheritance rights for a surviving partner equal to those of a surviving spouse.
- Protection from being treated differently than married spouses by any Nevada public agency.
Where Federal Law Falls Short
The biggest limitation of a domestic partnership is federal. The IRS does not consider registered domestic partners married, so you cannot file a federal return as married filing jointly or married filing separately.11Internal Revenue Service. Answers to Frequently Asked Questions for Registered Domestic Partners and Individuals in Civil Unions Other spouse-only federal rules, such as the $25,000 passive activity loss offset for rental real estate and certain community income rules, also don’t apply. And as noted above, domestic partners don’t qualify as spouses for FMLA leave.6U.S. Department of Labor. Fact Sheet #28L – Leave Under the Family and Medical Leave Act
Ending a Domestic Partnership
A domestic partnership can be ended through a simplified filing with the Secretary of State when both partners agree, when they have resolved any issues around property, support, and child custody (or have none to resolve), and when both waive the right to a fuller court process.12Nevada Legislature. Nevada Revised Statutes 122A.300 – General Requirements and Procedures for Termination If any of those conditions isn’t met, termination has to go through a court proceeding similar to a divorce.
If You’re Already Living Together Without Marrying
Nevada law provides limited protections to unmarried couples who find themselves in disputes over property or relationship status.
The Putative Spouse Doctrine
The Nevada Supreme Court has adopted the putative spouse doctrine, which protects someone who participated in a marriage ceremony with an honest and reasonable belief that the marriage was legally valid.13Justia. Williams v. Williams If the marriage later turns out to be void, say because one party had a prior undissolved marriage, the partner who acted in good faith can still receive an equitable share of property acquired during the relationship under community property principles. Good faith is presumed; the person claiming bad faith has to prove it. The court has also said this doctrine does not entitle a putative spouse to spousal support, only to property division.
Implied Agreements Between Cohabitants
Unmarried couples who live together have no community property rights. Property acquired during cohabitation belongs to whichever partner holds title or can prove ownership. Nevada courts will, however, enforce implied agreements to share property. If you pooled money to buy a home, held yourselves out as married, or otherwise acted as though you intended to share assets, a court may divide the property as if community property rules applied. Even homemaking contributions have been recognized as enough to support a claim against a former partner’s estate. Without that kind of evidence, a cohabitant whose name isn’t on the title generally has no property interest and may be limited to a claim for unjust enrichment.
Because these claims turn on the specific facts, couples who choose to live together without marrying or registering a partnership should put any property-sharing understandings in writing.
