Utah is closing its unmarried-couple route, and almost nothing written about it is current

If you live in Utah with a partner you never formally married, there is a court process that can recognize your relationship as a marriage. The 2026 Legislature put an end date on it. After that date, no new petition can be filed at all.

1. Two things nearly every other source gets wrong — Utah recodified its family law from Title 30 into Title 81.
2. What the court is actually looking for — The petition may be filed only during the relationship, or within one year after it ends.
3. What you lose if the window closes — Everything that turns on being a spouse rather than a partner.
4. What to do about it — We have read the current statutory text and Utah’s own court guidance, and both say 5 May 2027.

Two things nearly every other source gets wrong

First, the section number changed. Utah recodified its family law from Title 30 into Title 81. The provision everyone still cites as § 30-1-4.5 is now § 81-2-408. If you are searching for it, or if a form or an article points you at the old number, that is why you are not finding current text.

Second, Utah never had common-law marriage in the way people mean it. Utah is routinely listed among the states that recognize common-law marriage. That is misleading. In every other such state the marriage simply exists once the elements are met — no paperwork, no court. In Utah it has always required you to file a petition and ask a judge. Nothing is automatic, and nothing happens if you do not act.

What the court is actually looking for

The statute lets a court recognize a marriage that was not solemnized where it finds a contract between two people who:

• are of legal age and capable of giving consent;
• are legally capable of entering a solemnized marriage;
• have cohabited;
• mutually assume marital rights, duties and obligations; and
• hold themselves out as, and have acquired a uniform and general reputation as, spouses.

There is also a timing rule inside the timing rule, and it catches people. The petition may be filed only during the relationship, or within one year after it ends. So a couple who separated two years ago is already out of time, whatever the 2027 date says.

And note what is not on that list: any number of years. There is no seven-year rule in Utah or anywhere else in the United States. Length of cohabitation is evidence of the elements above; it is not one of them.

What you lose if the window closes

Everything that turns on being a spouse rather than a partner. In practice:

• Medical decisions. Surrogate-decision statutes rank a spouse at or near the top. An unmarried partner is usually far down the list or absent from it entirely.
• Inheritance. Intestacy distributes to a surviving spouse and to blood relatives. A partner takes nothing without a will.
• The elective share. The statutory minimum a will cannot defeat belongs to spouses. There is no partner equivalent.
• The house, if it is in one name. A partner has no automatic right to remain in it.
• Funeral decisions, which run on their own hierarchy that also starts with a spouse.

Our page on what the law does when you repartner without remarrying goes through each of those with the statutes.

What to do about it

• If you want the relationship recognized, file before the window shuts. Utah’s own courts put it plainly on their self-help page: “This process is going away on May 5, 2027. Be sure to file your petition with the courthouse before May 5, 2027 if you would like to start this process before it goes away.” That is a court petition with evidentiary requirements, and the window closes for everyone on the same day. The same page tells anyone with questions about judicial recognition of a same-sex marriage that they “might want to get legal advice” — that is the courts’ own recommendation, in the one context in which they make it, and not ours.
• If you do not want to be married — and many people deliberately do not — the deadline is not your problem. What you need instead is the documents: a health-care power of attorney, a HIPAA authorization, a will, reviewed beneficiary designations, a disposition-of-remains designation, and a cohabitation agreement. Those get you most of the practical protection without the marriage, and they do not expire in 2027. The planning worksheet walks through them.
• Either way, do not rely on a list that says Utah recognizes common-law marriage. Check the current text of § 81-2-408, or ask someone who has.

Authority: Utah Code § 81-2-408, “Validity of marriage not solemnized,” as amended by Chapter 347, 2026 General Session, read on the Utah Legislature’s own site; and the Utah State Courts self-help page “Judicial Recognition of a Relationship as a Marriage,” which states that Utah “does not have common law marriage” and carries the 5 May 2027 warning. The provision was formerly numbered § 30-1-4.5. Checked 15 Sep 2026.

This page is about one deadline in one state. It is not legal advice and it is not a substitute for a Utah attorney, which is what a petition of this kind needs.
