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

Michigan abolished the formation of new common law marriages effective January 1, 1957, under MCL 551.2. No common law marriage can be formed in Michigan on or after that date. Common law marriages entered into in Michigan before January 1, 1957, remain fully valid. Michigan also recognizes a valid common law marriage that was formed in another state.

Does Michigan recognize common law marriage?

Michigan no longer allows couples to form a common law marriage within the state. MCL 551.2 defines marriage as a civil contract to which the consent of capable parties is essential, but the same statute provides that consent alone is not enough to effectuate a legal marriage on and after January 1, 1957. Under that provision, a valid Michigan marriage requires three elements: consent of legally capable parties, a marriage license obtained under MCL 551.101 or MCL 551.201, and solemnization as authorized by MCL 551.7 through 551.18.

Before January 1, 1957, Michigan recognized common law marriages formed under the general common law rule that required mutual present consent to be married, cohabitation, and public holding out as husband and wife. The 1957 effective date represents the legislature's prospective abolition of informal marriage formation. Marriages satisfying the common law requirements before that date remain legally valid and are not affected by the later statutory change.

Because the abolition is prospective only, any couple that established a valid common law marriage under Michigan's pre-1957 common law retains all the rights and obligations of a formally solemnized marriage. Those rights include intestate inheritance, spousal privilege in court proceedings, eligibility for survivor benefits, and standing to seek spousal support in a divorce proceeding.

Why Michigan abolished common law marriage in 1957

The 1957 change brought Michigan in line with a nationwide trend toward requiring formal marriage procedures. The legislature and courts have identified several policy rationales for requiring a license and ceremony: formal procedures create a clear public record of marital status, protect both parties by making the legal and financial consequences of marriage explicit before they are incurred, reduce evidentiary disputes about whether a marriage was ever formed, and simplify estate and benefits administration.

MCL 551.2 traces back to the Revised Statutes of 1846, but the sentence providing that consent alone is not enough to effectuate a legal marriage on and after January 1, 1957, was added later, by 1956 PA 44. The statutory history published with the section records the sequence: R.S. 1846, Ch. 83; CL 1948, 551.2; Am. 1956, Act 44, Eff. Aug. 11, 1956; Am. 1996, Act 324, Imd. Eff. June 26, 1996. The 1996 amendment is the most recent change to the section. Michigan courts have consistently applied that date as the dividing line between valid pre-existing common law marriages and unrecognized informal unions formed after abolition.

A couple that has lived together in Michigan for any length of time, presented themselves publicly as married, filed joint tax returns, and genuinely believed they were married has not formed a legally recognized marriage if the relationship began on or after January 1, 1957, and they never obtained a marriage license.

Pre-1957 common law marriages: what remains valid

If both parties to a relationship were living and cohabiting in Michigan before January 1, 1957, and at that time mutually agreed to be presently married, cohabited together as husband and wife, and held themselves out publicly as a married couple, a valid Michigan common law marriage may have been formed. That marriage did not dissolve when the 1957 statute took effect, and it has not been invalidated by any subsequent legislative change.

To establish that a pre-1957 common law marriage existed, a party typically must show evidence of the three traditional elements as they existed before January 1, 1957. Given the age of any such relationship, proof often depends on historical documents: old joint tax returns, deeds or titles identifying the couple as husband and wife, death certificates or obituaries, letters or family correspondence, affidavits from witnesses who knew the couple during the pre-1957 period, and similar historical records.

A pre-1957 common law marriage can only be dissolved the same way any marriage is dissolved: by divorce, annulment, or the death of a spouse.

Does Michigan recognize a common law marriage from another state?

Yes. Michigan gives full legal effect to a common law marriage that was validly formed in a state that permits such marriages. This recognition rests on the place-of-celebration rule (lex loci contractus), the long-standing choice-of-law principle that a marriage valid where it was contracted is valid elsewhere, applied through the doctrine of comity, under which the courts of one state recognize legal relationships validly created under the law of another state. The Full Faith and Credit Clause is not the source of this rule. Article IV, Section 1 of the United States Constitution requires each state to give full faith and credit to the "public acts, records, and judicial proceedings" of every other state, and a common law marriage produces none of those, because it is formed by the parties' agreement and conduct rather than by a license, a certificate, or a court judgment.

As of 2026, the states that still permit formation of new common law marriages include Colorado, Iowa, Kansas, Montana, Oklahoma (contested), Rhode Island, Texas (called "informal marriage" under Tex. Fam. Code section 2.401), and Utah (which requires a court or administrative order). The District of Columbia also recognizes common law marriage. A couple who validly formed a common law marriage in any of those jurisdictions and then moved to Michigan retains married status in Michigan.

Practically, this means that a couple with a valid out-of-state common law marriage is treated by Michigan courts and agencies as legally married for purposes of divorce, property division, spousal support, inheritance rights, intestate succession, and all other legal incidents of marriage under Michigan law.

To invoke Michigan recognition, a party must show that the marriage met the requirements of the state where it was formed. For example, a couple asserting a Texas informal marriage under Tex. Fam. Code section 2.401 must establish that they agreed to be married, cohabited in Texas, and represented to others that they were married.

How to prove a common law marriage formed in another state

Because a common law marriage leaves no license or official certificate, the burden of proving the marriage rests on the party asserting it. The standard of proof and the specific elements depend on the law of the state where the marriage was formed. Michigan courts evaluating an out-of-state common law marriage look at the same categories of evidence that courts in the forming state would consider.

Evidence commonly considered includes:

• Joint federal or state income tax returns filed as "married filing jointly" or "married filing separately"
• Joint bank accounts, joint mortgage or lease agreements, or jointly titled real property
• Insurance policies or retirement account beneficiary designations listing the partner as a spouse
• Loan applications, government-benefits forms, or employer-benefits documents identifying the relationship as a marriage
• Testimony from family members, friends, neighbors, coworkers, or clergy who knew the couple as married
• Written correspondence, social media posts, or other documents in which the parties referred to each other as husband, wife, or spouse
• Use of a shared last name
• Affidavits signed by both parties or by knowledgeable third parties

No single item is conclusive. Courts assess the totality of the evidence against the requirements of the state where the marriage was allegedly formed.

The 7-year myth

A widespread belief holds that living together for 7 years automatically creates a common law marriage, or that separating for 7 years automatically dissolves one. Neither claim is true anywhere in the United States.

No state, including the states that still permit common law marriage formation, sets a minimum number of years of cohabitation as a requirement or automatic trigger. The states that allow common law marriage formation focus on mutual intent and conduct: a present agreement to be married, cohabitation in the permitting state, and public representation of the marital relationship. Duration of cohabitation may be circumstantial evidence of intent, but no fixed number of years is required or sufficient by itself.

In Michigan, this point is particularly clear because common law marriage formation has been prohibited since January 1, 1957. No period of cohabitation after that date, whether 7 years or 57 years, creates a marriage in Michigan without a license and ceremony.

How a common law marriage ends in Michigan

A valid common law marriage, wherever it was formed, can only be terminated by formal legal divorce proceedings, annulment, or the death of a spouse. There is no such thing as a "common law divorce," and Michigan law provides no mechanism for informally dissolving a marriage.

Simply separating, dividing property informally, or ceasing to present as a married couple does not end a legal marriage. A Michigan resident with a valid pre-1957 Michigan common law marriage or a valid out-of-state common law marriage who "separates" without obtaining a divorce remains legally married. Attempting to remarry in Michigan without a prior divorce would create a void or voidable second marriage. If you separated from a common law spouse and never divorced, get a free case evaluation from a Michigan family lawyer on filing for divorce before either of you remarries (attorney advertising).

Divorce proceedings to dissolve a common law marriage in Michigan proceed under Michigan law in the same manner as any other Michigan divorce. The court applies Michigan's equitable distribution principles, the spousal support factors under MCL 552.23, and the same jurisdictional and procedural rules that govern any dissolution action.

Frequently Asked Questions

Does Michigan recognize common law marriage?

Michigan no longer allows new common law marriages to be formed in the state. MCL 551.2 abolished common law marriage formation effective January 1, 1957, by providing that consent alone is not enough to create a legal marriage on and after that date. A license and solemnization are required. Common law marriages validly formed in Michigan before January 1, 1957, remain fully recognized, and Michigan recognizes valid common law marriages formed in other states.

What is the cutoff date for common law marriage in Michigan?

January 1, 1957. MCL 551.2 states that consent alone is not enough to effectuate a legal marriage on and after January 1, 1957. Any common law marriage validly formed in Michigan before that date remains valid. No common law marriage can be formed in Michigan on or after January 1, 1957.

Is 7 years of living together considered common law marriage in Michigan?

No. This is a myth. Michigan does not allow common law marriage formation at all for relationships beginning on or after January 1, 1957. Even before that date, Michigan did not require any specific number of years of cohabitation. The 7-year figure has no basis in Michigan law or in the law of any other state.

Does Michigan recognize a common law marriage from another state?

Yes. Michigan recognizes a common law marriage that was validly formed in a state that permits such marriages, under the place-of-celebration rule and principles of comity rather than under the Full Faith and Credit Clause, which reaches public acts, records, and judicial proceedings. A couple who formed a valid common law marriage in Colorado, Texas, Iowa, or another permitting state and later moved to Michigan retains that marital status in Michigan.

How do you end a common law marriage in Michigan?

A valid common law marriage ends only through formal divorce, annulment, or the death of a spouse. There is no common law divorce. A couple with a valid pre-1957 Michigan common law marriage or a valid out-of-state common law marriage must obtain a divorce decree from an appropriate court. Simply separating or stopping cohabitation does not dissolve a legal marriage.

How do I prove a pre-1957 Michigan common law marriage?

Evidence of a pre-1957 Michigan common law marriage typically includes historical records showing the couple presented themselves as married before January 1, 1957: old joint tax returns, deeds or titles identifying both parties as husband and wife, death certificates, letters or family correspondence from the period, and affidavits from people who knew the couple as married at that time. Courts look at the totality of the evidence.

Which Michigan statute governs common law marriage?

MCL 551.2 is the key provision. It defines marriage as a civil contract requiring the consent of capable parties, but states that consent alone is not enough to effectuate a legal marriage on and after January 1, 1957. A valid Michigan marriage also requires a license under MCL 551.101 or MCL 551.201 and solemnization under MCL 551.7 through 551.18.
