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:
- Colorado
- Iowa
- Kansas
- Montana
- New Hampshire
- South Carolina
- Texas
- 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:
- Agreement to be married – The parties must have agreed to enter into a marital relationship. This typically means a present agreement to marry, not a promise to marry in the future.
- Cohabitation – The parties must have lived together (in most jurisdictions for a specified period, often one year or more).
- Holding out as married – The parties must have presented themselves to the public as husband and wife—through joint use of names, introduction to friends and family, holding joint accounts, etc.
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, gather and prepare:
- Witness testimony from friends, family, and colleagues about how you and your partner presented yourselves
- Joint financial records – Bank accounts, loans, credit cards held jointly
- Shared residences – Lease agreements, utility bills, mortgage papers showing both names
- Testimonials from employers or official records listing marital status
- Photographs and correspondence documenting your life together
- Testimony from your partner (if they acknowledge the marriage)
- Any written statements or documents where you both described yourselves as married
The stronger your evidence across multiple categories, the more convincing your case.
What Courts Look For
Judges understand that cohabitation doesn’t always equal marriage. A court will evaluate:
- How long you lived together – Longer cohabitation strengthens the case
- Public knowledge of the relationship – Did people in your community regard you as married?
- Financial entanglement – Did you intertwine your finances, suggesting marital intent?
- Children – Joint children suggest a marital relationship, but aren’t required
- Degree of commitment – Did you present the relationship as permanent and exclusive?
The presence of one factor might not be enough. 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
- New York’s equitable distribution laws apply to property division
- Spousal maintenance (alimony) may be relevant
- Child custody and support arrangements apply if you have children
- 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:
- Identify where the common law marriage was established and when
- Research that state’s specific requirements for common law marriage (they vary)
- Begin gathering evidence of cohabitation, shared finances, and holding out as married
- Preserve documents and keep witnesses’ contact information
- Consult an attorney before taking any legal action
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
- Creating a cohabitation agreement that spells out your rights and responsibilities
- Using wills, powers of attorney, and healthcare directives to specify decision-making authority
- Holding property jointly where appropriate or executing agreements about property rights
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.
