Common Law Marriage in Utah

Limited / conditional

In Utah, common law marriage is recognized only in limited circumstances.

Core requirements

• Court or administrative finding that a marriage existed
• Petition filed within 1 year after the relationship ended
• Mutual agreement, cohabitation and holding out during the relationship

How to prove a common law marriage in Utah

Proof usually combines several documents and facts: a signed statement or declaration of marriage, joint bank and credit accounts, tax returns filed as a married couple, shared leases or deeds, beneficiary and insurance forms that name each other, children listed with both parents, and testimony that you presented yourselves to the public as spouses. Courts weigh the overall picture, not any single item.

Recognition from other states

Under the U.S. Constitution Full Faith and Credit Clause, every state — including Utah — recognizes a valid common law marriage that was properly formed in another state. Moving across state lines does not undo a real marriage.
