Utah Divorce Laws (2026): Grounds, Residency, and Process

To file for divorce in Utah, you or your spouse must be an actual and bona fide resident of the county where the petition is filed for at least 90 days before filing. Utah's primary no-fault ground is irreconcilable differences, and no separation period is required. Note that Utah's family law code was renumbered from Title 30 to Title 81 effective September 1, 2024.

Grounds for divorce in Utah

Utah recognizes both no-fault and fault-based grounds for divorce. The primary no-fault ground is irreconcilable differences, meaning the parties simply cannot get along and the marriage cannot reasonably be saved. No period of living apart is required to use this ground. An alternative no-fault-style ground exists: living under a decree of separate maintenance for three years. Most Utah divorces proceed on irreconcilable differences.

Utah also retains a range of fault grounds under Utah Code 81-4-405: adultery; willful desertion for more than one year; willful neglect to provide for the family; cruel treatment causing bodily injury or great mental distress; habitual drunkenness; felony conviction; impotency at the time of the marriage; and incurable insanity. Fault grounds require proof in court and may influence the court's equitable-distribution analysis, but they are used in a minority of cases. Note that Utah's family law code was substantively renumbered from Title 30, Chapter 3 to Title 81, Chapter 4 effective September 1, 2024; the statutes are identical in substance, only the numbers changed.

Residency requirement

Before a Utah court will hear a divorce case, one spouse must be an actual and bona fide resident of the county where the petition is filed for at least 90 days immediately before filing (Utah Code 81-4-402). The statute sets a single county-based test; there is no separate statewide residency element layered on top of it. Bona fide residency means physically living in the county with the intent to remain there, not merely being present temporarily.

Utah Code 81-4-402 also provides two alternatives to the 90-day county residency. A petitioner who is a member of the United States armed forces and is stationed in Utah under military orders for at least 90 days may file, and so may parties where both spouses have consented to personal jurisdiction for the divorce.

Divorce cases in Utah are filed in the District Court for the county where the resident spouse lives. If both spouses are Utah residents in different counties, the petitioner may file in either county. There is no requirement that the responding spouse also be a Utah resident, though out-of-state service adds procedural steps.

Waiting period and separation

Utah imposes a 30-day waiting period from the filing of the petition before a divorce decree may be entered (Utah Code 81-4-402). This is a cooling-off period, not a separation requirement. Spouses can live together throughout the divorce process; nothing in Utah law requires them to live apart before or during the proceedings for the irreconcilable-differences ground.

Do not confuse the waiting period with a separation requirement. Utah has no mandatory separation period for a standard no-fault divorce. The three-year separate-maintenance ground requires a prior court decree of separate maintenance (a formal legal proceeding) and is rarely used in modern practice. In a typical Utah divorce, the parties file on irreconcilable differences, and the court may grant the decree any time after the 30-day window has elapsed. The court may waive the 30-day wait in exceptional circumstances, but this is uncommon.

How property is divided

Utah is an equitable distribution state, not a community property state. Unlike community property states (such as neighboring Nevada or Idaho), there is no automatic 50/50 split of marital assets in Utah. Instead, the court divides marital property in a manner that is fair and equitable given all the circumstances.

The court considers factors such as the length of the marriage, each spouse's financial situation and earning capacity, contributions to the marriage (including homemaking and child-rearing), tax consequences, and any fault that affected the marriage's economic condition. Separate property (assets owned before the marriage, or received during marriage by gift or inheritance and kept separate) is generally awarded to the owning spouse and not divided. Commingling separate property with marital funds can cause it to lose its separate character.

Alimony, custody, and child support

Utah courts may award alimony (Utah statutes use the term "alimony" rather than "spousal support") based on the receiving spouse's financial need, the paying spouse's ability to pay, and the standard of living established during the marriage. Utah also has a rebuttable presumption that alimony should not last longer than the marriage itself. For full details on eligibility and calculation, see the Utah alimony laws page.

Child custody decisions in Utah are made using the best-interest-of-the-child standard, and Utah courts encourage both parents to remain involved. Child support follows the Utah Income Shares Guidelines. Estimate your payment with our Utah child support calculator. Both custody and support are addressed alongside the divorce petition or in separate but concurrent proceedings. See the Utah child custody laws page and the Utah child support page for more information.

How to file for divorce in Utah

The process in Utah follows these practical steps. First, confirm that you or your spouse meets the 90-day county residency requirement or one of the statutory alternatives. Second, prepare the Petition for Divorce and related forms, available through the Utah Courts self-help center. File the petition with the District Court clerk in the appropriate county and pay the filing fee, which Utah Code 78A-2-301 sets at $350 for a petition under Title 81, Chapter 4, Dissolution of Marriage. Because the fee is fixed by statute, it is the same in every county and does not change based on whether children are involved. A counter-petition in the same action costs $130.

Third, serve your spouse with the petition and a summons according to the Utah Rules of Civil Procedure. Your spouse then has 21 days (if served in Utah) or 30 days (if served outside Utah) to file a response. Fourth, both parties exchange financial declarations and other required disclosures. Fifth, if you reach a complete agreement on property, alimony, and (if applicable) custody and child support, you may submit a Decree of Divorce and supporting documents for the judge's signature after the 30-day waiting period. Sixth, if the case is contested, the court schedules mediation or hearings, and a trial may follow. Seventh, the judge signs the Final Decree of Divorce, which ends the marriage. There is no additional waiting period after the decree is entered.
