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

North Dakota does not recognize common law marriage formed within the state. Under N.D.C.C. 14-03-10, no marriage may be solemnized in North Dakota without a valid license, and N.D.C.C. 14-03-09 limits who may perform that solemnization. North Dakota has never enacted a statute permitting informal marriage formation, so there is no grandfather cutoff date for North Dakota-formed unions. North Dakota does, however, recognize a common law marriage that was validly formed in another state.

Does North Dakota recognize common law marriage?

North Dakota does not allow couples to form a common law marriage within the state. The North Dakota Century Code title 14, chapter 03 governs marriage in North Dakota, and its requirements are formal and procedural. N.D.C.C. 14-03-10 provides that no marriage may be solemnized without a license issued under that chapter. N.D.C.C. 14-03-09 identifies the officials and clergy authorized to solemnize a marriage. Together, these provisions establish the license and ceremony as mandatory prerequisites to a valid North Dakota marriage.

North Dakota has never enacted a statute recognizing common law marriage formation. Unlike states such as Alabama or Ohio that recognized common law marriage for a period of time and later abolished it by setting a prospective cutoff date, North Dakota simply never adopted the doctrine. Because there was no prior recognition to abolish, there is no grandfather date for informal unions formed within the state.

The practical consequence is straightforward: a couple that cohabits in North Dakota for any number of years, holds itself out publicly as married, files joint tax returns, and genuinely considers itself married has nonetheless not formed a legally recognized marriage under North Dakota law without a license and ceremony. Intent and cohabitation, however longstanding, do not substitute for the statutory formalities.

Why North Dakota requires a license and solemnization

North Dakota's formal marriage requirements reflect the legislature's policy choice to maintain a clear, public record of marital status. The license requirement creates an official record through the county recorder's office before the ceremony takes place. The solemnization requirement ensures a recognizable event marks the transition to married status.

These requirements serve several purposes that courts and legislators across the country have identified over time: they protect both parties by making the legal consequences of marriage clear at the outset, they create a public record that simplifies questions of inheritance, property rights, and benefits eligibility, and they avoid the evidentiary difficulties that arise when parties later dispute whether a marriage was ever formed at all.

N.D.C.C. 14-03-01 defines what constitutes marriage in North Dakota, establishing the foundational framework into which the license and solemnization requirements fit. Because the code has never included a provision permitting informal or common law marriage formation, the absence of such a statute is itself the legal rule.

For couples who cohabit in North Dakota without marrying, the state does not provide a parallel legal status equivalent to marriage. Long-term cohabiting partners do not acquire marital rights simply by living together, regardless of the duration or nature of the relationship.

Does North Dakota recognize a common law marriage from another state?

Yes. North Dakota gives full legal effect to a common law marriage that was validly formed in a state that permits such marriages. This recognition flows from two sources.

The first is the Full Faith and Credit Clause of the United States Constitution, Article IV, Section 1, which requires each state to give credit to the public acts, records, and judicial proceedings of other states. Federal statute 28 U.S.C. 1738 implements this clause procedurally, governing how another state's acts, records, and judicial proceedings are authenticated and admitted into evidence in North Dakota courts. Once properly authenticated, a marriage record valid in the state where it was formed can be used as evidence of that marriage in North Dakota.

The second source is the common law doctrine of comity, under which courts recognize legal relationships validly created in other jurisdictions as a matter of interstate legal harmony.

Practically, this means that a couple who formed a valid common law marriage in Colorado under C.R.S. 14-2-109.5, in Texas under Texas Family Code section 2.401, in Iowa based on the intent-and-holding-out standard, or in any other state that still permits common law marriage formation, retains that marital status when the couple moves to North Dakota. North Dakota courts treat the couple as legally married for purposes of divorce, property division, spousal support, inheritance, intestate succession, and all other legal incidents of marriage.

To establish North Dakota recognition of an out-of-state common law marriage, a party must show that the claimed marriage met all of the requirements of the state where it was allegedly formed. For example, a couple asserting a Colorado common law marriage must show mutual agreement to enter the marital relationship and conduct manifesting that agreement, the two-part test adopted in In re the Marriage of Hogsett & Neale, 2021 CO 1, 478 P.3d 713. Hogsett replaced Colorado's older multi-factor test and held that no single factor, including public reputation as a married couple, is independently required; courts weigh the totality of the parties' conduct instead.

How to prove a common law marriage formed in another state

A common law marriage leaves no license or certificate. The burden of proving that one exists falls on the party asserting it. The standard of proof and the specific elements are governed by the law of the state where the marriage was allegedly formed, but courts reviewing such evidence look at a consistent set of categories.

Evidence courts commonly consider includes:

• Joint federal and state income tax returns filed as married filing jointly or married filing separately
• Joint bank accounts, credit accounts, or investment accounts opened in both names
• Deeds, leases, or mortgage documents listing both parties as husband and wife or as spouses
• Life insurance policies or retirement account beneficiary designations naming the other party as a spouse
• Loan applications, credit applications, or government-benefit forms identifying the relationship as a marriage
• Testimony from family members, friends, neighbors, coworkers, clergy, or others who knew the couple as married
• Correspondence, cards, social media posts, or other written records in which the parties referred to each other as husband, wife, or spouse
• Use of a shared last name or documented use of the other partner's last name
• Affidavits signed by both parties acknowledging the existence of a marriage

No single piece of evidence is automatically conclusive. Courts look at the totality of the relationship to determine whether the parties genuinely agreed to be married and held themselves out as married under the law of the state where the marriage was allegedly formed.

The 7-year myth

A widespread misconception holds that living together for seven years automatically creates a common law marriage. This is false in every state 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 an automatic trigger. The states that allow common law marriage focus on the intent and conduct of the parties: a mutual present agreement to be married, cohabitation in the permitting state, and public representation of the marriage to the community. Duration of cohabitation may be relevant as circumstantial evidence of the parties' intent, but there is no fixed number of years that by itself creates a marriage.

In North Dakota, where common law marriage formation is not permitted at all, the point is especially clear. No period of cohabitation in North Dakota, whether seven years or forty years, creates a legal marriage without a license and ceremony. The seven-year figure has no basis in North Dakota law or in the law of any other state.

How a common law marriage ends

A valid common law marriage, wherever it was formed, can only be terminated by formal divorce proceedings or by the death of a spouse. There is no such thing as a common law divorce, and no informal act dissolves a legal marriage.

This rule has significant practical consequences for North Dakota residents. A person with a valid out-of-state common law marriage who moves to North Dakota and separates from the other party without filing for divorce remains legally married under North Dakota law. Attempting to marry a new partner in North Dakota without first obtaining a divorce would create a void or voidable second marriage.

North Dakota divorce proceedings for a valid common law marriage formed in another state follow the same rules as any other North Dakota divorce under N.D.C.C. chapter 14-05. The court applies North Dakota dissolution law to property, spousal support, and any parenting issues.
