The short answer
Living together does not create a marriage anywhere in the United States, no matter how many years pass. A small number of states plus the District of Columbia still allow common-law marriage, and each requires that the couple agreed to be married at a specific point, lived together, and presented themselves publicly as spouses. Once formed, it is a real marriage that only a divorce can end.
What is a common-law marriage, exactly?
It is a marriage formed without a license or a ceremony, by agreement and conduct alone. Where it exists, the result is not a lesser status or a halfway arrangement. It is a full marriage with every consequence attached: inheritance rights, spousal benefits, the marital privilege in court, tax filing status, and the obligation to go through a divorce to get out.
The rule that surprises people most is what it does not require. There is no minimum number of years. The widely repeated idea that seven years of living together produces a marriage is folklore. It has no source in any state statute, and courts have rejected it for as long as the myth has circulated. Two people can form a common-law marriage in a week if the elements are met, and two people can live together for forty years without ever forming one.
What the doctrine does require is a specific moment of mutual agreement to be married right now, not a plan to marry later. An engagement is the opposite of what the doctrine needs, because an engagement is an agreement to marry in the future. That distinction decides a large share of contested cases, and it is why the question of what happens to a ring when an engagement ends sits in an entirely different part of the law.
Which places still recognize it?
A shrinking minority. The clear pattern over the last century has been abolition: legislatures decided that a status this consequential should not turn on disputed recollections of a private conversation. Fewer than ten states still allow a new common-law marriage to form, along with the District of Columbia.
The jurisdictions commonly counted in that group include Colorado, Iowa, Kansas, Montana, Oklahoma, Rhode Island, Texas, and the District of Columbia. Utah belongs in a category of its own, because it requires a court or administrative determination that the relationship met the statutory test rather than treating the marriage as self-executing. New Hampshire sits in another category, recognizing the relationship only for purposes of settling a deceased partner's estate rather than during both partners' lifetimes.
Because this list moves, and because a state's own courts refine what its statute means, treat the group above as the shape of the landscape rather than a final answer for your situation. Your state court's self-help office or a family-law practitioner in that state can tell you the current position, and the question is worth an hour of paid advice whenever money or inheritance depends on it.
What about states that abolished it?
Almost every abolition was prospective. The legislature picked a cutoff and said that no new common-law marriage may form after it, while leaving intact every marriage that had already come into existence. That is a deliberate choice, because unwinding existing marriages would have stripped inheritance and benefit rights from people who had relied on them for decades.
So the question in an abolition state is not whether common-law marriage is recognized today. It is whether this particular couple met the elements before that state's cutoff. Several states have abolished the doctrine within living memory, which means there are couples in each of them whose marriage is valid on the strength of conduct from years earlier.
There is a second and larger group of cases: couples who formed a valid common-law marriage in a recognizing state and then moved. Under ordinary conflict-of-laws principles, a marriage valid where it was contracted is generally treated as valid elsewhere, and a state that no longer permits informal marriage to form inside its borders will usually still recognize one that formed properly somewhere else. That is the same principle that governs recognition of marriages across state and national borders, and it is why moving does not dissolve anything.
What do you actually have to show?
The wording varies by state, but the elements collapse into four questions a court will ask.
- Capacity. Both partners were of age, of sound mind, and free of any existing marriage at the moment of agreement.
- Present agreement. They agreed to be married then and there, rather than agreeing to marry someday.
- Cohabitation. They lived together as spouses. Some states require this to continue; others treat a period of it as enough.
- Holding out. They presented themselves publicly as married, so that the community they lived in understood them that way.
Holding out is the element that decides most contested cases, because it is the one that leaves a paper trail. Private intentions are unprovable; public representations are not. A couple who agreed privately to be married but filed separate tax returns, listed themselves as single on loan applications, and never used spousal language with employers, doctors, or landlords will have a hard time convincing anyone.
Courts also look for consistency. A couple who claimed to be married when it helped and single when it helped invites the argument that neither claim was sincere. Judges notice that pattern and it damages credibility on every other issue in the case.
What evidence do courts find convincing?
Documents created during the relationship, for reasons unrelated to this dispute, carry far more weight than testimony created after it. The strongest proof is boring, contemporaneous, and made when neither partner had anything to gain.
| Kind of evidence | Examples | Why it carries weight |
|---|---|---|
| Government filings | Joint tax returns, benefit applications listing a spouse, a filed declaration of informal marriage | Made under penalty of perjury, before any dispute existed |
| Financial records | Joint accounts, a mortgage or lease in both names, shared insurance policies | Show the pooling of resources spouses typically undertake |
| Designations | Beneficiary forms, emergency contacts, health-plan enrollment as a spouse | Requires a deliberate choice to use the word spouse |
| Community proof | Testimony from employers, neighbors, clergy, and family about how the couple was known | Goes directly to the holding-out element |
| Everyday usage | Shared surname, correspondence addressed to both as spouses, obituaries and announcements | Corroborates the pattern without being self-serving |
Evidence that cuts the other way is equally powerful. Tax returns filed as single, a separate residence, a benefits application that named no spouse, or a will that described the other person as a friend can sink an otherwise plausible claim. If you believe you are common-law married, the practical advice is to stop generating inconsistent records now and to consider filing a formal declaration if your state offers one.
A common-law marriage that is proved after a partner's death changes who inherits, who receives survivor benefits, and who controls the estate. A partner who assumes the relationship was informal and never confirmed it may find the question decided by a probate judge weighing scraps of paper. If your state offers a recorded declaration, filing it costs very little and removes the argument entirely.
How does a common-law marriage end?
By divorce, death, or annulment. Nothing else. There is no such thing as a common-law divorce, and separating, moving out, or telling everyone the relationship is over does not dissolve the marriage. A partner who remarries without divorcing may be committing bigamy and may create a second marriage that is void from the start, which is where the analysis in void and voidable marriages becomes urgent rather than theoretical.
This produces a recurring trap. One partner claims the marriage existed in order to reach property or support; the other denies it in order to keep them. Some states shorten the window by requiring a proceeding to be brought within a set period after separation, after which the law presumes no agreement was ever made. Where that limit exists, waiting is expensive.
If you were never common-law married and never will be, that is a settled position rather than a problem, but it is one worth planning around. Unmarried partners have no automatic claim to each other's property or income, and the tools that fill the gap are ordinary ones: written agreements, joint titling, and the authority documents described in how partners give each other medical and financial authority. Deciding deliberately is always cheaper than letting a court reconstruct your intentions later.
What to remember
- There is no number of years that turns cohabitation into marriage; the myth of a seven-year rule has no basis in law.
- Most states that abolished informal marriage still honor ones formed before the cutoff date their legislature chose.
- A valid common-law marriage must be ended by divorce, exactly like a licensed one, and cannot simply be walked away from.
- Proof usually turns on documents created while the relationship was intact rather than testimony offered afterward.
- Claims most often surface in probate, benefit applications, and separations, when one partner has an incentive to deny it.
Other questions people ask
Can a couple be common-law married for some purposes but not others?
In practice, yes. A federal agency deciding a benefits claim, a state probate court, and an employer's health plan each apply their own standard of proof to the same facts. One may accept the marriage while another does not. The determinations are independent, so winning at one agency does not bind the next.
Does a written agreement between partners create a common-law marriage?
Not by itself, though it can be strong evidence of the required present agreement. Some states offer a formal declaration of informal marriage that partners sign and file with the county, which converts a disputed factual question into a recorded document. Where that option exists, it is the cheapest protection available.
What happens if one partner was still married to someone else?
No valid common-law marriage forms while either partner has an undissolved prior marriage. Some states apply a doctrine that lets the informal marriage take effect automatically once the earlier one ends, if the couple keeps living as spouses. Others require a fresh agreement afterward, so the timing matters.
