If you’ve been living with a partner for years, sharing finances, and calling each other “husband” or “wife” without ever getting a marriage license, you might be wondering whether the law already considers you married. The answer depends entirely on where you live — and it’s more complicated than most quick internet answers suggest.
Common-law marriage isn’t a nationwide option. It’s been abolished, restricted, or grandfathered out in most of the country, and the handful of states that still allow it each have their own quirks and cutoff dates. Get this wrong, and you could be blindsided during a breakup, a death, an insurance claim, or a tax filing — either by discovering you’re legally married when you thought you weren’t, or by discovering you have none of the protections you assumed you had.
This guide walks through exactly which states currently recognize common-law marriage, which ones only honor marriages formed before a certain date, what you actually need to prove one exists, and what to do if you’re unsure where you stand.
What Common-Law Marriage Actually Means
Common-law marriage is a legally recognized marriage formed without a marriage license, officiant, or ceremony. Where it’s allowed, a couple can be considered legally married purely based on their conduct and mutual understanding — not paperwork.
That said, no state recognizes common-law marriage based on cohabitation alone. Simply living together for a long time, even decades, does not automatically make you married anywhere in the United States. That’s one of the most persistent myths on this topic, and it trips up a lot of people who assume there’s some magic number of years involved.
To have a valid common-law marriage in a state that permits it, courts generally look for three elements together:
- Cohabitation — the couple lives together as partners.
- Mutual consent to be married right now — both partners genuinely consider themselves married, not just planning to marry eventually.
- Holding out as married — the couple presents themselves publicly as spouses, through things like using the same last name, filing joint tax returns, referring to each other as “husband” or “wife,” or listing each other as spouse on insurance and medical forms.
Courts weigh all three together. A couple who lives together and even has children but consistently describes themselves as “partners” rather than spouses on official documents may not meet the legal bar, even in a state that recognizes common-law marriage.
States That Currently Allow New Common-Law Marriages
As of 2026, a small number of jurisdictions still allow couples to form a new common-law marriage:
- Colorado
- Iowa
- Kansas
- Montana
- Oklahoma
- Rhode Island
- Texas
- Utah (with a notable difference — see below)
- District of Columbia
In most of these, meeting the three elements above is enough to be considered legally married, with all the same rights and obligations as a couple who went through a formal ceremony — including the need for a formal divorce to end the relationship, not just moving out.
Utah’s Unique Requirement
Utah stands apart from the others on this list. Rather than automatically recognizing a common-law marriage the moment the elements are met, Utah generally requires the relationship to be validated through a court or administrative process — often after one partner has died or the relationship has ended, when the legal status actually needs to be established for something like inheritance or benefits. In practice, this means a Utah couple can’t simply assume they’re common-law married; someone typically has to formally establish it.
A Word on Changing Cutoff Rules
Several of these states have tightened their rules over the past two decades, restricting common-law marriage to relationships that began before a specific date rather than eliminating it altogether. Colorado, Iowa, and Kansas have each adjusted their requirements or cutoff dates in recent years, so if your relationship began some time ago, it’s worth checking the exact date your state’s rule refers to rather than assuming the current law applies retroactively — or that an old law still applies today.
States With Limited or Conditional Recognition
Two states sit in a gray area worth understanding on their own.
New Hampshire recognizes common-law marriage only for inheritance purposes, and generally only after one partner has died. It doesn’t function as a full marital status for tax filing, health insurance, or divorce while both partners are living. This narrow purpose surprises a lot of people who assume New Hampshire is a full common-law marriage state.
South Carolina used to fully recognize common-law marriage but stopped allowing new ones as of July 24, 2019, following a state supreme court ruling. Couples who met all the requirements before that date are still considered validly married; anyone whose relationship developed those characteristics afterward is not, no matter how long they’ve lived together since.
“Legacied-In” States: Only Marriages Formed Before a Certain Date
A number of states abolished common-law marriage going forward but chose to honor marriages that already existed under the old rules. If your relationship began before the relevant cutoff date in one of these states, it may still be legally recognized — but nothing formed afterward will be:
- Alabama — recognized if formed before January 1, 2017
- Florida — recognized if formed before January 1, 1968
- Georgia — recognized if formed before January 1, 1997
- Idaho — recognized if formed before January 1, 1996
- Indiana — recognized if formed before January 1, 1958
- Ohio — recognized if formed before October 10, 1991
- Pennsylvania — recognized if formed before January 1, 2005
If you fall into one of these categories, proving your marriage typically means demonstrating that all three elements — cohabitation, mutual intent, and public holding out — were already in place before the cutoff, which can require old documents, witness testimony, or joint financial records from that period.
What About Every Other State?
The remaining states never permitted common-law marriage or abolished it entirely without any grandfather provision. If you live in one of these and never had a formal ceremony and marriage license, you are not legally married there, regardless of how long you’ve been together or how “married” your life looks in practice.
This matters more than it might seem. Without a legal marriage, you generally don’t have automatic rights to a partner’s property after death, inheritance without a will, spousal health insurance eligibility, next-of-kin medical decision-making authority, or the property division and support protections that come with divorce. Couples in this position who want those protections typically need to get married formally or use legal tools like wills, powers of attorney, healthcare proxies, and cohabitation agreements to replicate some of those protections contractually.
Does Moving to a New State Change Your Marital Status?
If you validly formed a common-law marriage in a state that allows it, does it still count if you move somewhere that doesn’t?
Yes. Under the Full Faith and Credit Clause of the U.S. Constitution, every state recognizes marriages — including common-law marriages — that were validly formed in another state or jurisdiction that permits them. If a couple meets Texas’s requirements for common-law marriage while living there and later moves to New York, which doesn’t allow new common-law marriages to form, they remain legally married. New York simply won’t let a couple form a new one within its own borders.
This cuts both ways, though. It also means a couple who moves to a common-law marriage state without meeting the requirements there doesn’t suddenly become married just by relocating — the elements still have to be met under that state’s specific rules.
Common Pain Points and Misunderstandings
“We’ve lived together for seven years, so we must be common-law married.” This is the single most common misconception. No U.S. state has ever recognized common-law marriage based purely on a number of years cohabiting. Mutual intent and public holding out as married both have to be present as well.
“We filed joint taxes once, so that settles it.” A single joint filing isn’t automatically decisive, but it can be meaningful evidence when combined with other consistent behavior. Courts generally look at the overall pattern of conduct over time, not one isolated document.
“We have a common-law marriage, so we don’t need a will.” Even where common-law marriage is fully valid, it doesn’t automatically replace the need for estate planning. A will still clarifies asset distribution and can prevent disputes, especially with blended families, prior marriages, or complicated inheritance situations.
“We want to end things — do we need a divorce?” In a state where you’re validly common-law married, yes. Ending a common-law marriage requires a formal divorce, exactly like ending a ceremonial marriage. You can’t simply move out and consider the marriage over.
Frequently Asked Questions
Is there a minimum number of years required for common-law marriage? No. No U.S. state sets a specific length of cohabitation as a legal requirement for common-law marriage. What matters is whether the couple mutually intends to be married and consistently presents themselves as a married couple, regardless of whether that took two years or twenty.
Can same-sex couples form a common-law marriage? Yes, in any state that recognizes common-law marriage, the same requirements apply regardless of the couple’s sex, consistent with nationwide marriage equality established by Obergefell v. Hodges in 2015.
How do you prove a common-law marriage exists? Common forms of proof include joint tax returns, shared bank accounts or leases, insurance documents listing each other as spouse, affidavits or testimony from friends and family, and consistent use of the same last name or spousal titles. Courts weigh the overall pattern of evidence rather than requiring one specific document.
Can you have a common-law marriage in a state that doesn’t recognize it if you formed it elsewhere first? Yes. As long as the marriage was validly formed under the laws of a state or jurisdiction that permits common-law marriage, other states are constitutionally required to recognize it, even if they don’t allow new ones to form within their own borders.
Do you need a lawyer to end a common-law marriage? Ending a valid common-law marriage requires a formal legal divorce, just as it would for a ceremonial marriage — including property division and, where applicable, spousal support. While it’s technically possible to file without an attorney, most people benefit from legal guidance given how document-intensive proving or contesting a common-law marriage’s validity can be during a divorce.
Key Takeaways
Common-law marriage survives in a small, specific set of places — Colorado, Iowa, Kansas, Montana, Oklahoma, Rhode Island, Texas, Utah (with its validation requirement), and Washington, D.C. — plus a handful of states that only honor relationships formed before a particular cutoff date. Nowhere does simply living together for a long time create a marriage on its own; intent and public acknowledgment as a married couple both have to be present too.
If you’re unsure whether your relationship meets the legal bar in your state, or you’re trying to plan ahead for property, healthcare decisions, or what happens if the relationship ends, it’s worth having a family law attorney in your specific state review your situation directly. State rules on this topic shift more often than people expect, and getting a clear answer now is far easier than untangling it during a dispute later.
