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

Massachusetts does not allow couples to form a new common law marriage within the state. Massachusetts abolished common law marriage effective July 12, 1977, and the Supreme Judicial Court confirmed in Wilcox v. Trautz, 427 Mass. 326 (1998), that no common law marriage can be formed in Massachusetts after that date. Common law marriages validly entered into before July 12, 1977, remain legally recognized. Massachusetts also recognizes a common law marriage validly formed in another state that still permits such marriages.

Does Massachusetts recognize common law marriage?

Massachusetts abolished common law marriage on July 12, 1977. After that date, no couple can form a valid common law marriage within Massachusetts. Any Massachusetts relationship that began on or after July 12, 1977, no matter how long it has lasted, how publicly the parties held themselves out as married, or what mutual understanding they believed they had, does not create a legally recognized marriage in Massachusetts without a formal license and ceremony.

The abolition date is the critical fact for most people asking about Massachusetts common law marriage today. Relationships that began after mid-1977 cannot be grandfathered, because the grandfathering provision protects only marriages that were actually formed before the abolition date.

The Massachusetts Supreme Judicial Court addressed this issue directly in Wilcox v. Trautz, 427 Mass. 326 (1998). In that case, the court confirmed that common law marriage no longer exists as an available legal status in Massachusetts. The court held that cohabitation and mutual intent to be married, without formal solemnization, do not create a valid marriage under current Massachusetts law. The Wilcox decision remains the controlling authority on this question.

Massachusetts General Laws Chapter 207 governs marriage in the Commonwealth. The chapter establishes a comprehensive framework requiring notice of intention (section 20), a certificate issued by the town clerk (section 28), solemnization by an authorized person (section 38), and registration of the ceremony. This statutory scheme provides no pathway for informal marriage formation after the 1977 abolition.

Grandfathered common law marriages formed before July 12, 1977

A common law marriage that was validly formed in Massachusetts before July 12, 1977, remains legally recognized in Massachusetts. The abolition of common law marriage was prospective, not retroactive, meaning the legislature terminated the institution going forward while preserving the legal status of pre-existing informal unions.

For a pre-1977 Massachusetts common law marriage to be valid and grandfathered, the parties must have met the elements that Massachusetts law required at the time the marriage was allegedly formed. Under pre-abolition Massachusetts common law, those elements included a present mutual agreement to be married, cohabitation as a married couple, and public representation of the relationship as a marriage. All three elements had to be satisfied before July 12, 1977.

Proving a common law marriage formed nearly fifty years ago requires compelling evidence. Massachusetts courts look at contemporaneous documents, including tax returns, insurance designations, bank records, property titles, and correspondence from the relevant period, as well as testimony from witnesses who knew the couple during that time. The burden of proof rests on the party asserting the marriage.

For practical purposes, the pool of individuals who could claim a valid pre-1977 Massachusetts common law marriage is very small today. Most such claims arise in estate proceedings or survivor-benefit disputes involving elderly parties.

Does Massachusetts recognize a common law marriage from another state?

Yes. Massachusetts gives full legal recognition to a common law marriage that was validly formed in a state that still permits such marriages. This recognition follows from the Full Faith and Credit Clause of the United States Constitution, which requires each state to give effect to the public acts, records, and judicial proceedings of every other state, and from the doctrine of comity, under which courts recognize foreign legal relationships that were valid where created.

A couple who formed a valid informal marriage in Texas under Texas Family Code section 2.401, or in Colorado under C.R.S. section 14-2-109.5, and who later moved to Massachusetts, retains full marital status in Massachusetts. Massachusetts courts treat the couple as legally married for purposes of divorce, property division, spousal support, intestate inheritance, and all other legal incidents of marriage.

This rule also applies to a couple who formed a valid common law marriage in Massachusetts before July 12, 1977, then moved away and later returned. The pre-1977 Massachusetts marriage remains valid on their return.

To obtain Massachusetts recognition of an out-of-state common law marriage, a party must establish that the marriage satisfied the requirements of the state where it was formed. Massachusetts courts will apply the law of that other state to evaluate whether the marriage was validly created, not Massachusetts law.

How to prove a common law marriage formed in another state

A common law marriage leaves no license or certificate, so the party asserting the marriage must produce other evidence. The categories of evidence that courts consider when evaluating a claimed out-of-state common law marriage in Massachusetts proceedings are similar across jurisdictions.

Evidence courts commonly consider includes:

• Joint federal and state tax returns filed as married filing jointly or married filing separately
• Joint bank accounts, joint mortgage or lease agreements, or jointly titled property
• Insurance policies listing the partner as a spouse or dependent
• Loan applications, employer benefit enrollment forms, or government records identifying the relationship as a marriage
• Testimony from family members, friends, coworkers, neighbors, or clergy who knew the couple as a married pair
• Written correspondence, social media profiles, or documents in which the parties refer to each other as husband, wife, or spouse
• Use of a shared surname
• Affidavits executed by both parties affirming the marriage

Massachusetts General Laws Chapter 207, section 47, provides that marriage may be proved by evidence of general repute, cohabitation of the parties as married persons, or any other fact from which it may be inferred. That evidentiary provision applies to proving existing marriages, not to forming new ones.

No single piece of evidence is determinative. Courts weigh the whole picture to determine whether the parties genuinely agreed to be married and represented themselves as married, as required by the law of the state where the marriage was allegedly formed.

The 7-year cohabitation myth

A widespread misconception holds that living together for 7 years automatically creates a common law marriage. This is false in every state in the United States, including states that still allow common law marriage formation, and it is completely inapplicable in Massachusetts.

No state that permits common law marriage sets a minimum number of cohabitation years as a requirement. The relevant elements are the present mutual agreement of the parties to be married, cohabitation in the permitting state, and public representation of the marriage. Duration of cohabitation is relevant only as circumstantial evidence of intent, not as a standalone trigger.

In Massachusetts, no period of cohabitation creates a marriage after July 12, 1977. A couple that has lived together in Massachusetts for 7 years, or 27 years, without a license and ceremony is not legally married in Massachusetts, regardless of any mutual understanding or public representation.

How a common law marriage ends

A valid common law marriage, wherever it was formed, can only be terminated by a formal legal divorce, annulment, or the death of a spouse. There is no such thing as a common law divorce or an informal dissolution of a marriage. Moving apart, ending the relationship, or entering a new partnership does not end a valid marriage.

This rule has significant practical consequences. A person who formed a valid common law marriage in Colorado or Texas, moved to Massachusetts, and then separated without filing for divorce is still legally married under Massachusetts law. If that person later marries another partner in a Massachusetts ceremony, the second marriage is void because the prior valid marriage remains in force.

Massachusetts courts dissolve common law marriages formed in other states through the same divorce proceedings and under the same legal standards that govern the dissolution of any Massachusetts marriage. The court applies Massachusetts divorce law, including the alimony provisions under Massachusetts General Laws Chapter 208 and the child support guidelines, to the dissolution.

For context on what that process may involve financially, see Massachusetts alimony laws and Massachusetts child support laws.
