Common Law Marriage in Utah: Legal Requirements and Exceptions

While many U.S. states have abolished common law marriage, Utah remains one of the few that still recognizes it—though with specific legal conditions.

Unlike a traditional marriage that involves a ceremony and license, common law marriage in Utah (officially called a “marriage by agreement”) requires that both partners meet certain criteria and may need court approval to be legally recognized.

This article explains the legal requirements, benefits, and exceptions related to common law marriage in Utah in 2025.

Is Common Law Marriage Legal in Utah?

Yes, Utah recognizes common law marriage, but it must be validated through a legal process. The state does not automatically presume a couple is married simply because they’ve lived together for a certain number of years. Instead, couples must petition the court to have their relationship formally recognized as a marriage.

Legal Requirements for Common Law Marriage in Utah

For a court to approve a common law marriage in Utah, the following conditions must typically be met:

1. Both Parties Are of Legal Age and Capable of Consent
   Each partner must be at least 18 years old (or 16 with parental and court consent) and mentally competent.
2. They Are Not Legally Married to Anyone Else
   Neither party can be in a current legal marriage with another person.
3. They Mutually Agree to Be Married
   There must be evidence of mutual intent to be married, such as referring to each other as spouses, sharing finances, or naming each other as beneficiaries.
4. They Live Together
   Cohabitation is required, although Utah does not specify a minimum duration.
5. They Present Themselves as Married
   The couple must demonstrate to friends, family, or in public records that they consider and represent themselves as a married couple.

Court Approval: How to Make It Legal

To legally establish a common law marriage in Utah, a couple must file a petition in a district court. The petition should include evidence of their relationship and mutual agreement.

A judge will then determine whether the legal criteria have been met and issue an order recognizing the relationship as a valid marriage.

Once approved, the marriage is treated the same as a traditional one, with full rights to alimony, property division, and inheritance under Utah law.

Time Limit to Apply

There is a time limit to seek recognition. A petition must be filed during the relationship or within one year after the relationship ends (due to death or separation).

Failing to file within this period can result in the inability to claim legal marital rights retroactively.

Benefits of Common Law Marriage in Utah

Once recognized, a common law marriage in Utah grants the same rights and responsibilities as a traditional marriage, including:

• Property rights and division in case of separation
• Eligibility for spousal support (alimony)
• Inheritance and survivorship rights
• Access to health insurance and tax benefits
• Parental rights and responsibilities (if applicable)

Exceptions and Important Considerations

• Not Automatic: Simply living together does not make a couple legally married.
• Proof Is Crucial: Courts require convincing evidence, such as joint bank accounts, insurance policies, or affidavits from friends and family.
• No Out-of-State Recognition Without Approval: Other states may not recognize a Utah common law marriage unless it has been validated by a Utah court.
• Same-Sex Couples: Common law marriage is available to all couples regardless of gender, following the U.S. Supreme Court ruling on marriage equality.

Final Thoughts

Common law marriage in Utah is legal but requires a court’s recognition to access full marital rights. Couples must prove mutual intent, cohabitation, and public acknowledgment of the relationship.

If you’re in a long-term partnership and want legal security, especially in areas like inheritance or medical decision-making, it’s wise to consider petitioning for legal recognition—or opt for a formal marriage license.
