Utah Common Law Marriage Law Is Changing: What You Need to Know

If you’ve lived with a partner for years, shared bills, and told everyone you’re married even though you never had a ceremony or a marriage license, Utah law may already treat you as married. That’s true today. It won’t stay true much longer. A new law that took effect May 6, 2026 puts a hard deadline on Utah common law marriage, and couples in Salt Lake County and across the state need to understand what it means before that window closes for good.

For decades, the Third District Court and other Utah courts have heard petitions asking a judge to formally recognize a relationship as a marriage even though the couple never solemnized it. Senate Bill 110 doesn’t erase that option overnight. It puts an expiration date on it. Here’s what changed, who it affects, and what you should do if you think it applies to you.

What Common Law Marriage Has Meant in Utah

Utah has never recognized common law marriage the way people picture it in states like Texas or Colorado, where a couple can become legally married just by living together and calling each other spouses. Utah has always required a court to sign off first. Lawyers and judges call it an “unsolemnized marriage,” and the concept traces back to the Utah Supreme Court’s 1994 decision in Whyte v. Blair, 885 P.2d 791 (Utah 1994), which recognized that a marriage-like relationship could be legally valid even without a license or ceremony.

The legislature eventually wrote that standard into statute, first at Utah Code § 30-1-4.5 and then, after the 2024 recodification of Utah’s family law into Title 81, at Utah Code § 81-2-408. To have an unsolemnized marriage recognized, a couple has to show they were both of legal age and capable of consenting, legally free to marry, living together, mutually taking on the rights and duties of marriage, and known in their community as spouses. All five factors have to be there. Missing even one usually means no marriage.

What Senate Bill 110 Changed

Senate Bill 110, sponsored by Sen. Todd Weiler, took effect May 6, 2026 and rewrote Utah Code § 81-2-408. The court-recognition standard itself didn’t change much. What changed is the timing.

Under the new law, an individual has until May 5, 2027 to file a petition asking a court to validate an unsolemnized marriage. A petition generally has to be filed while the relationship is ongoing, or within one year after it ends. Once May 5, 2027 arrives, the door closes completely: the statute now says no one may file this kind of petition on or after that date. There’s no grace period and no case-by-case exception built into the law.

In practice, this means Utah is winding down its unsolemnized marriage doctrine on a fixed timeline rather than eliminating it outright. Couples who might qualify have roughly a one-year runway from the law’s effective date to get into court, and couples who haven’t started that process yet need to move.

A Recent Utah Case Shows the Standard Is Already Strict

Even before Senate Bill 110, Utah courts weren’t quick to find an unsolemnized marriage just because a couple lived together and acted married in public. The Utah Court of Appeals made that clear in Daniel v. Daniel, 2025 UT App 193.

In that case, a couple divorced after seventeen years of marriage, then continued living together off and on for six more years, sharing finances and telling friends and family they were still married. When the relationship finally ended, one spouse asked the court to recognize an unsolemnized marriage for those six years. The court of appeals affirmed the denial, holding that marriage is contractual and requires actual mutual consent between both parties, not just appearances. One spouse’s repeated refusal to agree to remarry was enough to defeat the claim, regardless of how the couple presented themselves to the outside world.

The lesson for anyone considering a petition: cohabitation and reputation in the community help, but Utah courts still want proof that both people genuinely agreed to be married to each other.

Why This Deadline Matters for Unmarried Couples

A lot of long-term couples in Utah have never gotten legally married but assume, correctly under current law, that a court could recognize their relationship as a marriage if it ever became necessary. That backstop is what’s disappearing.

Marital status affects far more than a wedding ring. It affects who inherits property if a partner dies without a will, who can make medical decisions in a hospital, how property gets divided if the relationship ends, and eligibility for spousal benefits through retirement plans, insurance, and Social Security. Without a legally recognized marriage, a surviving or separating partner often has to rely on separate, harder legal theories like unjust enrichment or contract claims, which don’t offer the same protections divorce and probate law provide to spouses.

After May 5, 2027, couples who never solemnized their relationship and never filed a petition will have no path to ask a Utah court to treat them as married, no matter how long they’ve been together or how the community has always viewed them as a couple.

What To Do Before May 5, 2027

Couples who think they meet the legal standard have two real options. The first is filing a petition now, while the relationship is intact, rather than waiting until a breakup or a death forces the issue. The second is getting formally married through a licensed ceremony, which sidesteps the entire unsolemnized marriage question and remains available with no expiration date.

Petitions are filed in the district court for the county where the couple lives: the Third District Court for Salt Lake County and Summit County residents, or the Fourth District Court in Provo for Utah County residents. Given how closely Utah courts scrutinized the facts in Daniel v. Daniel, gathering solid proof of mutual consent, shared finances, and community reputation matters well before a hearing date, not after.

Frequently Asked Questions About Common Law Marriage in Utah

Q: Does Utah still recognize common law marriage in 2026?

A: Yes, but only through a court petition, and only if that petition is filed before May 5, 2027. After that date, Utah Code § 81-2-408 no longer allows new petitions at all.

Q: What do I have to prove for a Utah court to recognize an unsolemnized marriage?

A: You and your partner both need to have been legal age and capable of consenting, free to marry, living together, mutually taking on marital rights and duties, and known in your community as spouses. Courts look closely at whether both partners actually agreed to be married, not just how the relationship looked from the outside.

Q: What happens if I miss the May 5, 2027 deadline?

A: You lose the ability to ask any Utah court to recognize the relationship as a marriage. Without that recognition, rights tied to marriage, like inheritance, property division, and spousal benefits, generally won’t apply.

Q: Can I file if my relationship has already ended?

A: Generally yes, as long as you file within one year after the relationship ended and before the May 5, 2027 cutoff. Waiting past either deadline forecloses the claim.

Q: Do I need a lawyer to file an unsolemnized marriage petition?

A: It isn’t required, but recent cases like Daniel v. Daniel show courts hold petitioners to a real evidentiary standard. A family law attorney can look at your specific facts and tell you honestly whether they meet Utah’s test before you file.
