If you’ve been living with your partner for years, sharing bills, maybe even introducing each other as “husband” or “wife,” you may have wondered: are we legally married without ever signing a marriage certificate?
It’s a fair question, and the answer is more complicated than most people assume. Common law marriage isn’t a myth, but it also isn’t as widespread — or as easy to fall into — as popular culture suggests. Only a handful of states still recognize it, and even in those states, you can’t just “wait long enough” and become married by default.
This guide walks through what common law marriage actually requires, where it’s still legally recognized, how courts decide if one exists, and what happens if you need to end one. Whether you’re trying to understand your rights, planning for the future with a long-term partner, or dealing with a breakup, you’ll leave with a clear, accurate picture — not the version you’ve heard secondhand.
A quick note before we dive in: laws vary by state and change over time, so nothing here should replace advice from a licensed family law attorney in your state. Think of this as the foundation you need before that conversation, not a substitute for it.
What Is Common Law Marriage, Exactly?
Common law marriage is a legally recognized marriage that exists without a marriage license or a formal ceremony. Instead of a piece of paper, the couple’s actions and public representation of their relationship establish the marriage in the eyes of the law.
That said, “we’ve lived together for seven years” is not the legal standard, no matter how often you hear that number repeated. There’s no state where a specific number of years of cohabitation automatically creates a marriage. That’s one of the most persistent myths about the concept, and it trips people up constantly.
Where common law marriage is recognized, a couple generally has to meet all of these conditions at the same time:
- Both partners are legally eligible to marry (of legal age, not already married to someone else, mentally competent to consent)
- The couple lives together
- The couple intends to be married — not just partnered, but actually married
- The couple presents themselves to the public as a married couple
That last point is where most common law marriage cases actually get decided. Courts look for evidence like shared last names, joint tax filings as “married,” referring to each other as spouse in front of others, or naming each other as spouse on insurance and medical forms.
Which States Still Recognize Common Law Marriage?
This is the part people get wrong most often. Common law marriage used to be recognized more broadly across the U.S., but most states phased it out over the last century. As of now, only a small number of states allow new common law marriages to be established:
- Colorado
- Iowa
- Kansas
- Montana
- Oklahoma (recognition is inconsistent and has faced legal challenges)
- Rhode Island
- Texas
- Utah (requires a formal validation process through the courts or a signed declaration)
- District of Columbia
A few additional states deserve a special mention because they still recognize common law marriages that were already established before a certain cutoff date, even though they no longer allow new ones:
- Georgia (only if established before January 1, 1997)
- Idaho (only if established before January 1, 1996)
- Ohio (only if established before October 10, 1991)
- Pennsylvania (only if established before January 1, 2005)
- New Hampshire (recognized only for limited purposes, such as inheritance, after one partner dies)
Every other state does not recognize common law marriage at all, no matter how long a couple has lived together. If you live in one of those states, cohabitation — even decades of it — does not create legal marital rights, obligations, or protections on its own.
One more wrinkle worth knowing: most states honor the “full faith and credit” principle, meaning if you legally established a common law marriage in a state that permits it, other states will generally still recognize that marriage even after you move, even if the state you moved to doesn’t allow new common law marriages to form.

The Requirements Courts Actually Look For
Because there’s no license or ceremony, proving a common law marriage exists usually only becomes an issue during a dispute — most often a breakup, a death, or a disagreement over property or benefits. When that happens, courts examine the relationship as a whole rather than checking a single box.
Judges typically weigh:
Intent to be married. Did both partners genuinely consider themselves married, or were they simply committed partners who chose not to marry? This is often the hardest element to prove, since it lives inside people’s private understanding of their relationship.
Cohabitation. The couple needs to have lived together, though the required length of time varies by state and, in most states, isn’t fixed by statute at all — it’s evaluated case by case.
Holding out as married. This is the public-facing evidence: joint bank accounts under “married” status, health insurance listing a spouse, wedding rings, referring to each other as husband/wife/spouse in social settings, or filing joint tax returns as a married couple.
Legal capacity. Both people must have been free to marry — old enough, of sound mind, and not already married to someone else at the time.
A useful way to think about it: common law marriage isn’t something that quietly happens to a couple over time. It’s something a couple actively builds through consistent, public, and mutual behavior that reflects an actual marriage — not just a serious relationship.
Common Law Marriage vs. Cohabitation vs. Domestic Partnership
These three terms get used interchangeably in everyday conversation, but they carry very different legal weight.
Cohabitation simply means two people live together. On its own, it creates no automatic legal rights to each other’s property, no spousal support obligations, and no inheritance rights if one partner dies without a will.
Domestic partnership is a separate legal status that some states, counties, and employers offer, usually granting a defined set of rights (like health insurance eligibility or hospital visitation) without requiring the couple to meet the “holding out as married” standard that common law marriage does. It has to be formally registered — it isn’t something that develops naturally over time.
Common law marriage, when recognized, carries the same legal weight as a marriage performed with a license and ceremony. That means the same rights to property division, spousal support, inheritance, and tax status — and, importantly, the same legal process required to end it.
The practical takeaway: if you’re in a long-term relationship in a state that doesn’t recognize common law marriage, cohabitation alone won’t protect you financially if the relationship ends or your partner passes away. That’s usually where a cohabitation agreement or updated estate planning documents come in.
How Do You Prove — or Disprove — a Common Law Marriage?
If a common law marriage becomes disputed, either partner may need to prove it existed (often to claim spousal rights) or disprove it (often to avoid divorce proceedings or a property claim). The kind of evidence that tends to matter most includes:
- Joint tax returns filed as “married filing jointly”
- Shared bank accounts, credit cards, or property titled jointly
- Insurance policies listing one partner as the other’s spouse
- Consistent use of a shared last name
- Sworn statements from friends or family who knew the couple as a married pair
- Text messages, cards, or social media posts referring to each other as spouse
- Wedding rings or a wedding-style celebration, even without a license
No single piece of evidence guarantees a court will recognize the marriage. Judges look at the full pattern of behavior over time. This is also why disputes over common law marriage can get contentious — one partner may sincerely believe they were married, while the other insists they were simply committed, long-term partners.
Ending a Common Law Marriage: What Divorce Looks Like
Here’s the detail that surprises a lot of people: if a common law marriage is legally established, you cannot simply “break up” to end it. You have to go through a formal divorce, exactly like a couple who had a wedding and a marriage license.
That means:
- Filing for divorce through the court system
- Potentially dividing property according to your state’s marital property laws
- Addressing spousal support (alimony) if applicable
- Working out custody and child support arrangements if you have children together
- Following the same waiting periods and procedural steps as any other divorce in your state
This is often the moment reality sets in for couples who assumed common law marriage was a casual, low-commitment arrangement. Legally, once it’s established, it’s a marriage in every sense — which also means it comes with real legal protections, not just legal obligations.
If you’re not sure whether your relationship meets the bar for common law marriage in your state, and you’re facing a separation, that’s a conversation worth having with a family law attorney before you make major financial decisions. Getting it wrong in either direction — assuming you’re married when you’re not, or assuming you’re not when you are — can have lasting consequences.

Common Myths About Common Law Marriage
A few misconceptions come up so often they’re worth addressing directly:
“Seven years of living together automatically makes you married.” Not true anywhere in the U.S. No state has a fixed number of years that automatically creates a common law marriage.
“Common law marriage exists in every state.” Also false. It’s currently limited to a small handful of states plus D.C., with a few others honoring marriages formed before a specific cutoff date.
“You need a common law marriage certificate.” There’s no such document. The marriage is established through conduct and intent, not paperwork — although in Utah, couples can pursue a formal court validation if they want documented proof.
“If we’re not common law married, we have no rights at all.” Not entirely true. Even without marital status, unmarried couples can protect themselves through cohabitation agreements, wills, powers of attorney, and beneficiary designations — tools that don’t require marriage to be effective.
Frequently Asked Questions
Does common law marriage still exist in the U.S.? Yes, but only in a limited number of states — currently Colorado, Iowa, Kansas, Montana, Oklahoma, Rhode Island, Texas, Utah, and the District of Columbia allow new common law marriages to form. Several other states still recognize common law marriages established before a specific cutoff date, even though they no longer allow new ones.
How many years do you have to live together to be common law married? There is no fixed number of years in any state. Common law marriage depends on proving intent to be married and publicly presenting as a married couple, not simply on the length of time you’ve lived together.
Can you get a common law divorce? There’s no separate “common law divorce” process. If a common law marriage is legally established, ending it requires a standard divorce through the court system, including property division and, if applicable, spousal support and custody arrangements.
Does moving to a different state cancel a common law marriage? Generally, no. Under the full faith and credit principle, a common law marriage validly established in a state that recognizes it typically remains valid even after you move to a state that doesn’t allow new common law marriages to form.
What proof do you need for common law marriage? Courts typically look at joint tax filings, shared finances, insurance documents listing a spouse, consistent use of a shared name, and how the couple presented themselves to friends, family, and the public. No single document proves it — it’s based on the overall pattern of the relationship.
Key Takeaways
Common law marriage is real, but it’s narrower and more deliberate than most people assume. It’s only recognized in a small group of states, it requires more than just time spent living together, and once established, it carries the full legal weight of a traditional marriage — including the requirement of a formal divorce to end it.
If you’re in a long-term relationship and you’re unsure where you stand legally, the safest next step is a direct conversation with a family law attorney licensed in your state. They can review your specific situation — where you live, how long you’ve been together, and how you present your relationship publicly — and tell you plainly whether the law already considers you married, or what steps you might take to protect yourself either way.
