Common Law Marriage in New Jersey: Is It Recognized? (2026)

New Jersey does not allow couples to form a common-law marriage today. The state abolished new common-law marriages effective December 1, 1939, under N.J.S.A. 37:1-10. Any couple that established a valid common-law marriage before that date remains legally married, but no new common-law marriage has been possible in New Jersey for more than 80 years. New Jersey does, however, fully recognize a common-law marriage that was validly formed in another state that permits it.

Does New Jersey Recognize Common-Law Marriage?

New Jersey stopped allowing the formation of new common-law marriages on December 1, 1939. That change was enacted through what is now codified as N.J.S.A. 37:1-10, which provides that no common-law marriage contracted in New Jersey after that date shall be valid. The statute was a deliberate policy choice to require formal marriage ceremonies and licenses for all marriages going forward.

For the small number of couples whose relationship began and was established as a common-law marriage before December 1, 1939, the marriage remains legally valid. The abolition was prospective only: it ended the ability to create new common-law marriages but did not invalidate existing ones.

For virtually all New Jerseyans in 2026, the practical answer is straightforward. If you and your partner live together in New Jersey and never went through a licensed marriage ceremony in any state, you are not legally married under New Jersey law, no matter how long you have cohabited or how you have conducted yourselves publicly.

Why New Jersey Abolished Common-Law Marriage

New Jersey joined a broader national movement in the early 20th century to require marriage licenses and formal ceremonies as a matter of public policy. The concerns driving that movement were largely evidentiary and administrative. Common-law marriages were difficult to prove or disprove, creating uncertainty in inheritance disputes, property claims, and benefit determinations. Courts were regularly called upon to sort out conflicting testimony about whether parties had agreed to be married.

By requiring a license and ceremony, the state created a clear, documented record of every marriage. This simplified administration of estates, insurance claims, public benefits, and tax filings. New Jersey enacted the 1939 abolition statute as part of a general revision of its marriage laws, and the rule has remained unchanged since.

The legislature did not invalidate marriages that had already been established. Couples who had met the common-law requirements under prior law were not required to remarry formally, and their marriages continued with full legal effect.

Grandfathered Marriages: Before December 1, 1939

A common-law marriage formed in New Jersey before December 1, 1939, is fully valid. Under pre-abolition New Jersey case law, the essential elements of a common-law marriage were: (1) the parties had legal capacity to marry, meaning they were both unmarried and of sufficient age; (2) there was a present agreement or consent between the parties to be married to each other; and (3) the parties cohabited and held themselves out publicly as husband and wife.

No ceremony was required. No license was required. The agreement to be presently married, combined with holding out as a married couple, was sufficient.

Today, a person asserting a pre-1939 common-law marriage in a New Jersey court faces an evidentiary challenge because such marriages are now extremely old. Courts will look to documentary evidence such as tax returns, insurance records, bank accounts, and written correspondence, as well as testimony from people with firsthand knowledge. The burden of proof is on the party claiming the marriage existed.

Out-of-State Common-Law Marriages: New Jersey Recognizes Them

New Jersey honors a common-law marriage that was validly formed in a state that still permits such marriages or that permitted them at the time the couple entered into the relationship. This recognition follows from the legal principle of comity, under which states give effect to marriages validly contracted elsewhere, even if the home state would not permit that type of marriage to be formed locally.

States that still allow the formation of new common-law marriages as of 2026 include Colorado, Iowa, Kansas, Montana, Oklahoma, Rhode Island, Texas, and the District of Columbia, among others. If a New Jersey couple traveled to Texas, met the requirements of Texas law (mutual present agreement to be married, cohabitation, and holding out publicly as married), and established a valid Texas informal marriage, New Jersey courts would recognize that marriage when the couple returns to New Jersey.

The same principle applies to states that have since abolished common-law marriage but permitted it in the past. A couple that formed a valid common-law marriage in Pennsylvania before January 1, 2005, for example, carries a valid marriage with them regardless of which state they later live in.

Proof that the marriage was validly formed under the law of the other state is required. The party claiming the marriage bears the burden of demonstrating that the requirements of that other state were actually met.

How to Prove a Common-Law Marriage in New Jersey

When a common-law marriage is claimed in New Jersey, whether as a pre-1939 New Jersey marriage or as a marriage formed in another state, the party asserting the marriage must prove it by clear and convincing evidence. New Jersey courts look to a range of evidence:

Written declarations or agreements. Any written statement in which both parties affirmed their married status carries significant weight.

Joint tax returns. Filing federal or state income tax returns as "married filing jointly" or "married filing separately" is strong evidence of a mutual agreement to be married.

Joint financial accounts and property. Shared bank accounts, jointly titled real estate deeds, and jointly held investment accounts suggest that the parties regarded themselves as a married unit.

Insurance beneficiary designations. Naming a partner as a spouse on health, life, or other insurance policies is treated as an acknowledgment of married status.

Social Security and pension records. Government benefit records in which one partner listed the other as a spouse are probative.

Community reputation. Testimony from friends, family members, neighbors, employers, and religious community members that the couple presented themselves as married carries weight, particularly for older relationships.

No single piece of evidence is conclusive. Courts evaluate the totality of the circumstances to determine whether the parties genuinely entered into a present agreement to be married and consistently held themselves out as married.

How a Common-Law Marriage Ends

A valid common-law marriage, once established, is legally identical to a ceremonial marriage. It does not end simply because a couple separates, stops holding themselves out as married, or enters into a new relationship. The only way to dissolve a valid common-law marriage is through a formal divorce decree entered by a court of competent jurisdiction.

This means that if a couple validly formed a common-law marriage, either in New Jersey before 1939 or in another state that permitted it, and then one partner later marries someone else without first obtaining a divorce, that subsequent marriage is void for bigamy. New Jersey courts have addressed this issue in the context of estate claims, where a surviving partner in a later ceremonial marriage discovers that the decedent had a prior valid common-law marriage that was never dissolved.

There is no such thing as a "common-law divorce." The informality with which a common-law marriage can be formed does not extend to its dissolution. Formal court proceedings are required.

The Seven-Year Myth

Perhaps the most persistent misconception about common-law marriage is the belief that couples who live together for seven years automatically become legally married. This is false in every jurisdiction in the United States, including states that still permit common-law marriage.

No state sets a minimum or maximum period of cohabitation as the basis for establishing a common-law marriage. The required element is a mutual present agreement to be married, combined with holding out as a married couple. That agreement can exist after a short time or never arise at all despite decades of cohabitation.

In New Jersey, the question is moot because the state does not allow new common-law marriages to form regardless of duration. But the myth is worth debunking directly because it causes New Jerseyans to incorrectly believe they may have acquired marital rights from a long-term cohabiting relationship.

Cohabitation in New Jersey, without a marriage license and ceremony or a valid out-of-state common-law marriage, does not create marital rights. It does not entitle either partner to equitable distribution of property, spousal support, or inheritance rights as a spouse upon separation or death.
