Common Law Marriage: Which States Recognize It in 2026

Which states recognize common law marriage in 2026?

Eight states and D.C. currently provide a path for couples to form a new common law marriage. The list is short and has been shrinking for decades, so knowing exactly where you stand matters.

Two additional jurisdictions deserve a note. Utah doesn't let couples simply declare themselves married; a court or administrative body must confirm the relationship meets statutory requirements. New Hampshire has a narrow rule that applies only after three years of qualifying cohabitation that continues until one partner's death, making it relevant for inheritance purposes rather than a general path to marriage during both partners' lifetimes.

Several other states, including Alabama (before January 1, 2017), Georgia (before January 1, 1997), Idaho (before January 1, 1996), Pennsylvania (before January 1, 2005), Ohio (before October 10, 1991), and South Carolina (before July 24, 2019), still recognize common law marriages that were validly formed before their respective cutoff dates. No new ones can be created in those states.

What is a common law marriage and how is it different from just living together?

A common law marriage is a legally recognized marriage formed without a marriage license, certificate, or formal ceremony. Once established, it carries the same rights and obligations as a licensed marriage, including property rights, inheritance, spousal support eligibility, and tax filing status.

The distinction from simply living together is important. Cohabitation alone, no matter how long it lasts, does not create a marriage anywhere in the United States. To have a common law marriage, both partners must intend to be married, agree they are married in the present tense, and hold themselves out publicly as spouses. A domestic partnership or cohabitation agreement is a different legal arrangement that may provide some rights but does not create a marriage.

This difference has real practical consequences. If you and your partner split up after years of living together in a state that doesn't recognize common law marriage, you generally have no right to spousal support, property division under divorce laws, or survivor benefits. In a state that does recognize it, and you've met the requirements, you may need to go through a formal divorce to separate your legal and financial lives.

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

There is no minimum number of years. The widely cited "seven-year rule" is a myth, and no state has ever required a specific duration of cohabitation to create a common law marriage.

What matters is the quality of the relationship and whether both partners have a present mutual intent to be married. A couple that has lived together for six months, agreed they are married, and presented themselves publicly as spouses may have a valid common law marriage in a recognizing state. Meanwhile, a couple that has lived together for 20 years with no intent to be married does not have one.

The myth likely persists because people conflate the passage of time with legal status. But duration is, at most, one piece of circumstantial evidence a court might consider. It is never the determining factor on its own.

What are the requirements to form a common law marriage?

The core elements are consistent across recognizing states, though the exact standards and burden of proof differ. Generally, courts look for four things:

1. Legal capacity to marry. Both partners must be of legal age (18 in Colorado and Kansas, for example) and neither can be currently married to someone else.
2. A present mutual agreement to be married. This is the most important element. Both people must agree, in the present tense, that they are married now, not that they plan to marry someday. A promise to marry in the future does not qualify.
3. Cohabitation. The couple must live together in a state that recognizes common law marriage.
4. Holding out as spouses. The couple must represent themselves to the community as married, through actions like using the same last name, referring to each other as husband, wife, or spouse, filing joint tax returns, and sharing finances.

All elements typically must exist at the same time. Kansas courts, for instance, have emphasized that capacity, present agreement, and holding out must be proven simultaneously, not sequentially.

When one partner denies the marriage exists, a court may require clear and convincing evidence, a higher standard than the "preponderance of the evidence" used in many civil cases. This is where documentation and witnesses become important.

What evidence proves a common law marriage?

Courts look at the totality of the circumstances rather than checking off a single box. Common forms of evidence include:

• Joint federal or state tax returns filed as "married filing jointly"
• Shared bank accounts, credit cards, or loan applications listing both partners
• A shared last name or the use of spousal titles (husband, wife, spouse)
• A shared residence with both names on a lease, mortgage, or deed
• Insurance policies, retirement accounts, or beneficiary designations naming a partner as a spouse
• Testimony from friends, family, or community members who understood the couple to be married
• Joint ownership of property or vehicles

In Colorado, the Supreme Court's 2021 decision in In re Marriage of Hogsett clarified that courts must evaluate the totality of the circumstances rather than relying on any single piece of evidence. Factors like joint tax returns, shared bank accounts, a shared residence, and statements made to others all contribute to the analysis.

Evidence tends to matter most at moments of transition: after a separation when one partner seeks property division or spousal support, after one partner's death when the surviving partner claims inheritance or benefits, or when filing for Social Security survivor benefits. If you believe you may be in a common law marriage, keeping organized records of shared financial documents, joint accounts, and any written or public statements about your relationship can be valuable.

Common law marriage and property rights, inheritance, and benefits

A valid common law marriage gives both partners the same legal rights as a couple with a marriage certificate. Those rights include:

• Property division. In a divorce, marital property is divided according to the state's divorce laws, whether the state follows equitable distribution or community property rules.
• Spousal support (alimony). Either partner may be eligible for spousal support after divorce, just as in a licensed marriage.
• Inheritance. A surviving common law spouse generally has the right to inherit under intestacy laws if the deceased partner did not leave a will. They may also have elective share rights that override a will in some states.
• Tax filing. Common law spouses can file federal and state tax returns as married filing jointly, which may result in a lower tax rate depending on income levels.
• Social Security and benefits. A surviving common law spouse may qualify for Social Security survivor benefits, pension benefits, and health insurance coverage, provided the marriage is valid under state law.

Two practical points deserve attention. First, ending a valid common law marriage requires a formal divorce or legal dissolution. Simply separating, moving to a different home, or even moving to a state that doesn't allow common law marriage does not end the legal relationship. Until you obtain a divorce, you're still married, with all the financial and legal obligations that come with it.

Second, a common law marriage validly formed in one state is generally recognized by other states under the Full Faith and Credit clause and comity principles. If you and your partner became common law married in Colorado and then moved to California (which abolished common law marriage in 1895), California would typically still recognize your marriage as valid. This recognition applies to same-sex couples as well, following the Supreme Court's decision in Obergefell v. Hodges.

Because proof of a common law marriage can become complicated, especially during property disputes or benefits claims, consulting a family law attorney in your state is a practical step if you're uncertain about your status. An attorney can help you understand your state's specific burden of proof and gather the documentation you'd need.

Planning your financial life together

Whether you're in a common law marriage, planning a traditional wedding, or simply thinking about your future as a couple, organizing your financial and legal decisions early saves time and stress later. Topics like how you'll handle joint or separate accounts, beneficiary designations, tax filing strategies, health insurance decisions, and estate planning basics all benefit from a clear plan.
