New York does not recognize common law marriage. The state stopped allowing couples to form one on April 29, 1933, and no amount of living together, sharing finances, or holding yourselves out as married will give you the legal status of a married couple under New York law.1New York Department of Taxation and Finance. Legal Opinion L-RP-V1-111 To be married in New York, a couple must obtain a license and have the marriage solemnized by an authorized official, or sign a formal written contract with witnesses.2New York State Senate. New York Domestic Relations Law § 11
New York Does Not Allow Common Law Marriage
State courts refuse to treat informal arrangements as marriages regardless of how long the couple has been together or whether they have children in common.1New York Department of Taxation and Finance. Legal Opinion L-RP-V1-1112New York State Senate. New York Domestic Relations Law § 113New York State Senate. New York Domestic Relations Law § 13
One narrow exception: a common law marriage formed in New York before April 29, 1933, that met the legal requirements at the time can still be treated as valid.1New York Department of Taxation and Finance. Legal Opinion L-RP-V1-111 For anyone alive and partnering today, that door is closed.
Common Law Marriages From Other States
New York generally recognizes a common law marriage that a couple validly formed in a state that allows them. The basis is legal comity rather than a direct constitutional requirement. Courts look at whether the couple met the specific formation requirements of that other state, which typically include the couple’s intent to be married and how they represented themselves to others.4New York Official Reports. Matter of Lewis
A short visit to a common law state is usually not enough. The couple has to actually satisfy the other state’s rules while there.4New York Official Reports. Matter of Lewis Once New York does recognize the marriage, it treats the couple as married for most legal purposes, and ending the relationship requires a formal divorce or annulment rather than simply walking away.
Domestic Partnerships
Couples who don’t want to marry can register a domestic partnership through a local government office. In New York City, applicants must:
- Be at least 18 years old
- Live together in a committed relationship
- Not be currently married or in another domestic partnership
- Not be related in a way that would bar a legal marriage
The rights that come with a domestic partnership are narrower than those of marriage. Registered partners have hospital visitation rights similar to a spouse or next-of-kin.6New York State Senate. New York Public Health Law § 2805-q Certain government employees can extend health insurance coverage to their domestic partners through city-funded plans, but private-sector employers are not required to do the same.5New York State Department of Financial Services. OGC Opinion No. 00-09-08 Domestic partners do not receive the inheritance rights or tax advantages that go with marriage.
Legal Protections for Unmarried Couples
Because the law will not fill in for a missing marriage, unmarried partners in New York protect themselves through contracts and estate planning.
Cohabitation Agreements
A cohabitation agreement sets out how partners will divide property and handle financial obligations if the relationship ends. New York courts enforce express agreements between unmarried partners, and these agreements do not always have to be in writing.7New York Official Reports. Aitken v Aitken Agreements that transfer real estate interests generally must be in writing and signed to be valid.
Powers of Attorney and Health Care Proxies
A durable power of attorney lets one partner manage the other’s financial and legal matters if that partner becomes incapacitated.8New York State Senate. New York General Obligations Law § 5-1501A A health care proxy names a partner to make medical decisions when the other cannot.9New York State Senate. New York Public Health Law § 2981 Without these documents, an unmarried partner has no default authority to step in.
Wills and Inheritance
An unmarried partner is not an intestate distributee under New York law. If one partner dies without a will, the estate passes to a surviving spouse or blood relatives, not to the surviving partner. A will is the only reliable way for unmarried partners to leave property to each other. Domestic partnership status does not change this.
