Does Idaho Recognize Common Law Marriage?

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

Short answer

No, not for new relationships. Idaho abolished common law marriage as of January 1, 1996. Marriages formed before that date remain valid. Most states generally recognize a marriage that was valid where it was formed, so a common law marriage created in a state that allows it may still be recognized.

A common law marriage is a marriage created without a license or ceremony, by a couple who agree to be married, live together and present themselves as married. Only a minority of states still allow them.

What this means for unmarried couples

Couples who live together without a formal marriage do not automatically get spousal rights such as inheritance without a will, spousal support or a share of marital property. Partners who want protection can use written agreements, wills, beneficiary designations, joint titles and powers of attorney.

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.
