Common Law Marriage: Will New York Recognize Your Out-of-State Union?

You’ve been with your partner for years, never had a formal wedding ceremony, and you live together in New York. You think of each other as married—friends call you married, you present yourselves as married—but there’s no marriage certificate. Now you’re separating and wondering: are you legally married?

The answer depends on where your relationship developed and what laws applied there.

New York’s Clear Rule: No Common Law Marriage

New York abolished common law marriage in 1933. This means you cannot establish a common law marriage by living together in New York, no matter how long the relationship lasts or how much you and your partner present yourselves as married.

This is unambiguous. New York requires marriage through proper legal channels: a marriage license issued by a government clerk and a ceremony performed by an authorized official. Cohabitation, mutual consent, and the parties’ belief they’re married don’t create a valid marriage in New York.

What this means: If you and your partner have lived together in New York for 10, 15, or 20 years but never obtained a marriage license and conducted a ceremony, you’re not married under New York law—no matter what your friends or extended family call you.

The Caveat: New York Will Recognize Valid Common Law Marriages from Other States

Here’s where it gets more complicated. New York takes a different approach to common law marriages established in other states.

A handful of states still allow common law marriage, including Colorado, Iowa, Kansas, Montana, New Hampshire, South Carolina, Texas, and Utah.

If you established a common law marriage in one of these states—or in a state that allowed it at the time you were together—New York will likely recognize that marriage as valid for purposes of divorce.

Why? This reflects the principle that states generally recognize marriages validly entered into under another state’s law. If your common law marriage was valid where it was created, New York won’t invalidate it simply because New York itself doesn’t allow common law marriage.

Real-World Scenario

A couple moved from Colorado to New York after living together there for five years. Under Colorado law, they had established a valid common law marriage through cohabitation, mutual agreement, and holding themselves out as married. When they later moved to New York and separated, New York courts recognized their Colorado common law marriage as valid. This meant they required a formal divorce in New York, and the marriage was subject to New York’s divorce laws.

How to Prove a Common Law Marriage

If you’re claiming that a common law marriage was validly established in another state, New York courts require substantial evidence. This is where many common law marriage cases become complicated and contested.

The Typical Requirements

Most states that allow common law marriage require an agreement to be married—meaning the parties must have agreed to enter into a marital relationship with a present agreement to marry, not merely a promise to marry in the future. They also require cohabitation, with the parties living together for a specified period, often one year or more depending on the jurisdiction. Finally, they require that the parties hold themselves out as married to the public, presenting themselves as husband and wife through joint use of names, introductions to friends and family, holding joint accounts, and similar public indications of marital status.

Notably: Most states don’t require that the parties actually intend to create a common law marriage or understand the legal consequences. If their conduct meets the requirements, they’re married regardless of their subjective intent.

Evidence You'll Need

To prove a common law marriage, you'll need to gather and present a comprehensive collection of evidence. This includes witness testimony from friends, family, and colleagues about how you and your partner presented yourselves as a married couple. You should also compile joint financial records such as bank accounts, loans, and credit cards held jointly. Documentation of shared residences—including lease agreements, utility bills, and mortgage papers showing both names—strengthens your case. Testimonials from employers or official records listing your marital status, photographs and correspondence documenting your life together, testimony from your partner acknowledging the marriage, and any written statements or documents where you both described yourselves as married all contribute to establishing a common law marriage. The stronger your evidence across multiple categories, the more convincing your case becomes.

What Courts Look For

Judges understand that cohabitation doesn't always equal marriage, so they carefully evaluate several factors. The length of cohabitation matters, as longer periods of living together strengthen the case for a common law marriage. Public knowledge of the relationship is important—did people in your community regard you as married? Courts also examine financial entanglement, looking at whether you intertwined your finances in ways that suggest marital intent. The presence of joint children suggests a marital relationship, though children aren't required to establish a common law marriage. Finally, courts assess the degree of commitment you demonstrated by presenting the relationship as permanent and exclusive. Generally, the presence of one factor might not be enough, and courts typically want to see multiple, consistent indicators across your relationship.

Common Law Marriage vs. Domestic Partnership vs. Cohabitation

This is a point of confusion for many people.

Common law marriage is a legally recognized marriage established without formal ceremony—subject to specific state law requirements.

Domestic partnership is a legal status (recognized in some jurisdictions) that provides some rights and responsibilities similar to marriage but falls short of full marital status. New York doesn’t have a general domestic partnership statute, though some municipalities recognize it for limited purposes.

Cohabitation is simply living together. It creates no legal rights or responsibilities unless the parties have contracted differently (such as cohabitation agreements).

Implications for Your Divorce

If New York recognizes your out-of-state common law marriage, you're treated like any formally married couple. You must go through a formal divorce process in New York, and New York's equitable distribution laws apply to property division. Spousal maintenance (or alimony) may be relevant to your case, and if you have children, child custody and support arrangements apply as well. You're entitled to the same rights and subject to the same responsibilities as formally married couples.

What You Should Do If You’re in This Situation

If you believe you have a valid common law marriage from another state: Start by identifying where the common law marriage was established and when it began. Then research that state's specific requirements for common law marriage, as they vary significantly across jurisdictions. Begin gathering evidence of cohabitation, shared finances, and the fact that you held yourselves out as married. Preserve all relevant documents and keep witnesses' contact information organized. Finally, consult an attorney before taking any legal action to ensure you're proceeding with the strongest possible case.

If you're in a long-term cohabitation in New York and want legal protection: Since New York doesn't allow common law marriage, consider getting formally married through a civil or religious ceremony. You might also create a cohabitation agreement that spells out your rights and responsibilities to each other. Additionally, use wills, powers of attorney, and healthcare directives to specify decision-making authority in case of illness or death. Finally, consider holding property jointly where appropriate or executing agreements about property rights to protect both partners.

Protecting Yourself Going Forward

Many people in committed relationships—whether in New York or elsewhere—don’t formalize their legal status until a dispute arises. By then, it’s often too late to gather evidence or clarify intentions.

Better approach: If you’re in a long-term committed relationship, discuss your legal status and preferences with your partner. If you want marital rights and protections, get married. If you prefer not to marry, create an agreement that documents your intentions about property, finances, decision-making, and children.
