Many people assume that living together for a long time automatically creates a legal marriage. In most U.S. states, that is not true. However, a few states still recognize something called common law marriage, which can create legal marriage rights without a wedding or marriage license.
As of 2026, only a limited number of U.S. states still recognize new common law marriages. These include Colorado, Iowa, Kansas, Montana, Oklahoma (limited), Rhode Island, South Carolina (older relationships only), Texas, Utah, and the District of Columbia. Several other states recognize valid common law marriages established before they abolished the practice.
This article explains:
- What common law marriage really means
- Which states recognize it
- States that used to allow it
- States that never recognize it
- Why this matters for couples and legal professionals
All explained in simple, easy-to-understand language.
What Is Common Law Marriage?
Common law marriage is a legally recognized marriage created by behavior, not paperwork.
In states that allow it, a couple may be considered married if they:
- Live together
- Intend to be married
- Act like a married couple in public
No ceremony. No marriage license. Yet the law may treat them as legally married.
How Many States Recognize Common Law Marriage Today?
As of now, only a small number of U.S. states recognize common law marriage.
Most states do not allow it at all, while some recognize it only under very specific conditions.

States That Do NOT Recognize Common Law Marriage at All
Most U.S. states do not recognize common law marriage, no matter how long a couple lives together.
Examples include:
- California
- Florida

In these states:

- California may recognize the marriage because it was valid where created
This is based on long-standing U.S. legal principles.

Ending a common law marriage usually requires a formal divorce, just like a traditional marriage.
