Does Colorado Recognize Common Law Marriage?

Updated October 13, 2026 · 1 min read · 1 sources

Short answer

Yes. Colorado recognizes common law marriage. Since 2006, both parties must be at least 18 and not otherwise prohibited from marrying. A valid common law marriage is a full legal marriage, so ending it requires a divorce.

Living together for years does not by itself create a marriage. Where common law marriage exists, the couple must also agree they are married and present themselves to others as spouses.

How a common law marriage is usually proven

  • Evidence that both partners agreed to be married
  • Living together as spouses
  • Holding yourselves out as married: same last name, joint tax returns, insurance or bank accounts listing a spouse, and how friends and family know you

Disputes often arise after a breakup or a death, when one partner claims a marriage existed and the other side, or the other heirs, deny it. Clear documents help either way.

Couples who move between states

A common law marriage validly formed in a state that allows it is generally treated as a real marriage elsewhere, which means a divorce is needed to end it. If you lived in a state that recognizes common law marriage, get advice on whether a marriage may have been formed there.
