What Is Common Law Marriage? The Myth, the Reality, and Where It Still Exists

A common law marriage is a legally recognized marriage that a couple forms without a marriage license or formal ceremony. In the handful of states that still allow it, a couple becomes legally married, with all the rights and obligations of a licensed marriage, by meeting specific requirements: agreeing to be married, living together, and presenting themselves to others as a married couple. The catch is that common law marriage is widely misunderstood, only a small and shrinking number of states permit it, and simply living together for a long time does not make you common law married anywhere.

That last point is the big one, because the most common belief about common law marriage is flatly wrong. Here's what it actually is, what it takes, where it still exists in 2026, and why the myth causes real problems.

The myth: living together for X years

The single most widespread misconception is that if a couple lives together for a certain number of years, seven is the number people usually cite, they automatically become common law married. This is false. There is no state where merely cohabiting for a set period creates a common law marriage. The seven-year rule, and any specific-number-of-years rule, is a myth.

The confusion is understandable but consequential, because people rely on it and get hurt. A couple lives together for a decade, believes they're "basically married" by common law, and then one partner dies or the relationship ends, and the other discovers they have none of the legal rights a spouse would have, no inheritance rights, no claim to property in the other's name, no spousal benefits, because they were never actually married under the law. The belief that time alone creates a marriage leaves people unprotected precisely when they assumed they were protected.

Cohabitation is one element of common law marriage in the states that recognize it, but it's never sufficient on its own, and there's no magic number of years. Understanding that is the first step to understanding the real requirements.

The reality: what it actually takes

In the states that still recognize common law marriage, forming one requires several elements together, not just living together. The exact requirements vary by state, but they generally include three core components.

First, the couple must agree to be married, a present, mutual intent to be married now, not someday. This is the heart of it: both people must intend and agree that they are married, presently. Second, the couple must cohabit, live together, in the state that recognizes common law marriage. Third, the couple must "hold themselves out" as married, meaning they present themselves to the community as a married couple, using terms like husband, wife, or spouse, referring to themselves as married to friends, family, and others, and generally living publicly as a married couple. Evidence of holding out includes things like filing joint tax returns, using the same last name, sharing finances and accounts, and introducing each other as spouses.

When these elements are present in a recognizing state, the couple is legally married, just as if they'd gotten a license and had a ceremony. They have all the rights and responsibilities of marriage, property rights, inheritance rights, the obligations of marriage, and crucially, if they want to end the marriage, they must get a regular divorce. There's no such thing as a "common law divorce", once you're common law married, ending it requires the same legal divorce process as any other marriage. Some states have tweaked the requirements over time; Colorado, for example, relaxed its rule so that holding out publicly is weighed differently than before. But the basic structure, agreement, cohabitation, and holding out, is the consistent pattern.

Where common law marriage still exists in 2026

The number of states allowing new common law marriages has shrunk steadily over the decades as states abolished it, and as of 2026 only about eight states plus the District of Columbia still permit couples to form one.

The states that currently allow new common law marriages include Colorado, Iowa, Kansas, Montana, Rhode Island, Texas, and Utah, along with Washington, D.C. A couple of states occupy special categories: New Hampshire recognizes common law marriage only for inheritance purposes after a partner's death, treating a surviving partner as a spouse for inheritance if the couple lived together and acknowledged each other as spouses for several years before one died, but it does not treat living couples as common law married for other purposes. Oklahoma's status has been contested, with courts continuing to recognize common law marriage through case law despite uncertainty. And Utah's recognition is set to end in the coming years under a recent change, illustrating how the list keeps shrinking.

Beyond those, many states that abolished common law marriage still recognize ones that were formed before the abolition date, a "grandfather" rule. States like Pennsylvania, Ohio, Georgia, Idaho, South Carolina, Alabama, and others stopped allowing new common law marriages as of specific cutoff dates but continue to honor common law marriages validly created before those dates. So in those states, whether a common law marriage exists depends on when its elements were met relative to the cutoff.

The trend is clearly toward abolition, the recognizing states have been dwindling, and any couple relying on common law marriage should confirm their state's current status rather than assuming, because the law in this area genuinely changes.

The portability rule: recognized everywhere if validly formed

Here's a crucial wrinkle that protects couples and surprises people. Even though most states don't allow you to form a common law marriage within their borders, every state recognizes a common law marriage that was validly formed in a state that permits it.

This flows from the constitutional requirement that states give "full faith and credit" to legal relationships established in other states. So if a couple validly establishes a common law marriage in, say, Texas or Colorado, and then moves to a state that doesn't allow common law marriages to be formed, that state will still recognize them as legally married, because their marriage was valid where it was created. They don't lose their marriage by crossing a state line.

This matters for couples who formed a common law marriage in a recognizing state and later relocate, they remain married, with all the legal rights of marriage, in their new state. It also means the question of whether a couple is common law married can hinge on where they were living when the elements were met, which is exactly the kind of fact that gets litigated when a relationship ends or a partner dies.

How to protect yourself either way

The practical lesson of common law marriage is about clarity, because the ambiguity is what hurts people. If you want the legal protections of marriage, the cleanest path is a licensed marriage, which removes all doubt about your status. If you're in a recognizing state and believe you have a common law marriage, gathering evidence of the elements, joint accounts, joint tax filings, documents referring to each other as spouses, can matter enormously if your status is ever questioned.

And if you're a couple living together without wanting to be married, in any state, it's worth knowing that cohabitation alone generally gives you few of the legal protections marriage provides. Couples in that situation often use tools like cohabitation agreements, wills and beneficiary designations, and powers of attorney to create the specific protections they want, since living together doesn't automatically create them. Whether you want to be married or not, the key is not to rely on assumptions about common law marriage, but to take the concrete legal steps that match your actual intentions.

Frequently asked questions

How many years do you have to live together to be common law married?

There is no number of years that creates a common law marriage. The widespread belief in a "seven-year rule" is a myth, no state recognizes a couple as common law married simply for living together a certain length of time. In the states that allow it, common law marriage requires the couple to agree to be presently married, live together, and hold themselves out to others as a married couple. Time living together is one factor, but it's never enough on its own, and there's no magic threshold.

Which states recognize common law marriage?

As of 2026, only about eight states plus Washington, D.C. allow new common law marriages, including Colorado, Iowa, Kansas, Montana, Rhode Island, Texas, and Utah (whose recognition is ending soon), plus D.C. New Hampshire recognizes it only for inheritance purposes, and Oklahoma's status is contested. Many other states honor common law marriages formed before they abolished it. The list keeps shrinking, so confirm your state's current law rather than assuming.

Is a common law marriage recognized if you move to another state?

Yes. Every state recognizes a common law marriage that was validly formed in a state that permits it, under the constitutional principle of full faith and credit. So if you established a valid common law marriage in a recognizing state and then move to a state that doesn't allow new ones, you're still legally married there. Your marriage doesn't dissolve by crossing state lines, though proving it was validly formed may matter if your status is questioned.

Common law marriage is real but narrow, surrounded by a myth that leaves people unprotected when they assume rights they don't have. Knowing where it exists, what it actually requires, and how to take concrete legal steps to match your intentions is what protects you, whether you want to be married or not.
