Complete Guide to Utah Divorce Laws & Process

Utah's family law code was completely recodified effective September 1, 2024. What was formerly Title 30 is now Title 81 — Utah Domestic Relations Code. This guide uses the current Title 81 numbering throughout. Whether you're considering divorce, responding to a filing, or just trying to understand your rights, this is the definitive resource.

Residency Requirements

Before you can file for divorce in Utah, you must meet the state's residency requirement. Under Utah Code § 81-4-402(1), either spouse must have been a resident of Utah and of the county where the divorce is filed for at least 90 days (3 months) immediately before filing.

Grounds for Divorce

Under Utah Code § 81-4-405, Utah recognizes both no-fault and fault-based grounds for divorce.

How to File for Divorce in Utah: Step by Step

1. Confirm Residency Requirements

   Either spouse must have been a resident of Utah and of the county where the divorce is filed for at least 90 days immediately before filing (§ 81-4-402(1)).

2. Prepare Your Documents

   You'll need a Verified Petition for Divorce, Summons, Declaration of Jurisdiction and Grounds, Utah District Court Cover Sheet, and Certificate of Divorce (Utah Department of Health form). Utah's MyPaperwork system at mycase.utcourts.gov can help you generate these forms through a guided interview.

3. File with the District Court

   Submit your documents to the District Court clerk in the county where either spouse resides, or electronically through MyCase. Utah has 8 judicial districts covering all 29 counties. The filing fee is $325. Fee waivers are available for those who qualify based on financial need.

4. Serve Your Spouse

   You have 120 days to serve the petition, summons, and filed documents to your spouse. Service can be done through personal delivery (by a qualified person age 18+), certified mail with return receipt, or voluntary acceptance of service.

5. Wait for Response

   The respondent has 21 days (30 days if served outside Utah) to file an answer. If no answer is filed, the petitioner may request a default judgment.

6. Complete Mandatory Mediation (If Contested)

   If the respondent files an answer with contested issues, both parties must participate in at least one session of mediation in good faith before the case can proceed to trial (§ 81-4-403). Parties must select a mediator within 15 days and begin mediation within 45 days.

7. Complete Mandatory Education Courses

   If you have minor children, both parents must complete a Divorce Orientation Course and a Divorce Education Course before the divorce can be finalized. See the mandatory education section below for details.

8. Observe the 30-Day Waiting Period

   A judge cannot sign the final divorce decree until at least 30 days after the petition was filed (§ 81-4-402(3)). This waiting period can be waived by motion for good cause. Note: this was reduced from 90 days to 30 days in May 2018.

9. Finalize the Divorce

   Once all requirements are met (waiting period, education courses, agreement or court ruling on all issues), the judge reviews and signs the Decree of Divorce.

Contested vs. Uncontested Divorce

Many contested cases become uncontested through mediation. This is extremely common — and exactly what Utah's mandatory mediation law is designed to facilitate.

Child Custody in Utah

Utah distinguishes between legal custody (decision-making authority) and physical custody (where the child lives). Under § 81-9-101 et seq., the court considers the best interests of the child above all other factors.

Types of Custody

Best Interest Factors (§ 81-9-204)

When determining custody, Utah courts consider:

• The depth and quality of the bond between the child and each parent
• Each parent's ability to co-parent and encourage a relationship with the other parent
• The physical and mental health of the parents
• Any history of domestic violence, neglect, or substance abuse
• The child's preference (if of sufficient age and maturity)
• Each parent's demonstrated understanding of the child's developmental needs
• The benefit of keeping siblings together
• Which parent is more likely to allow frequent contact with the noncustodial parent

Parenting Plans (§ 81-9-203)

When joint custody is requested, each parent must file a proposed parenting plan including a dispute-resolution procedure, allocation of decision-making authority, a residential schedule, provisions for relocation notice, and transportation details between homes.

Child Support in Utah

Utah uses the Income Shares Model for calculating child support (§ 81-6-304). Both parents' gross incomes are used to determine a combined child support obligation, and each parent's share is proportional to their percentage of combined income.

Alimony / Spousal Support

Under Utah Code § 81-4-502, courts consider multiple factors when determining alimony. There is no automatic formula — each case is decided on its unique circumstances.

Factors the Court Considers

• The standard of living during the marriage (income, benefits, taxes)
• Financial condition and needs of the recipient spouse
• Earning capacity of the recipient spouse
• Ability of the payor spouse to provide support
• Length of the marriage
• Whether the recipient has custody of minor children
• Whether the recipient contributed to the payor's earning capacity (e.g., supporting them through school)
• Fault of the parties (in some circumstances)

Property Division: Equitable Distribution

Utah is an equitable distribution state — not a community property state. Under § 81-4-406, "equitable" means fair, not necessarily equal. The court won't automatically split everything 50/50.

Key principles:

• The court divides all marital property regardless of which spouse holds title
• Pre-marital property and inheritances are generally considered separate property and returned to the owning spouse
• Retirement and pension accounts contributed to during the marriage must be divided equitably (often requires a QDRO — Qualified Domestic Relations Order)
• Factors include length of marriage, age and health of parties, income and earning capacity, contributions to the household (including homemaking), and division of marital debt

Utah's Mandatory Mediation Requirement

Under Utah Code § 81-4-403:

David Musselman, Common Ground's founder, was the first non-lawyer appointed to Utah's Court Mediation Roster. With 25+ years of experience and over 8,000 families served, Common Ground has been part of Utah's mediation landscape since before mandatory mediation became law.

Mandatory Education Courses

Utah requires divorcing parents with minor children to complete two courses before the divorce can be finalized:

Court-approved online courses are available through Utah State University Extension at extension.usu.edu/divorce in English (with closed captions) and Spanish. Total cost for both courses: approximately $65 per parent.

Modifying a Divorce Decree

To modify custody, support, or alimony after the divorce is finalized, the petitioning party must demonstrate:

• A material (important) and substantial (major) change in circumstances since the decree was issued
• The change was not expressly anticipated in the original decree or findings

What can be modified: child custody arrangements, parent-time schedules, child support amounts, and alimony amounts and duration. Alimony modification specifically requires a "substantial material change in circumstances not expressly stated in the divorce decree" (§ 81-4-504).

Relocation Rules (§ 81-9-209)

If a custodial parent intends to move 150 miles or more from the other parent's residence:

• 60 days' advance written notice must be provided to the other parent
• If the other parent objects, the court holds a hearing to determine whether the relocation is in the child's best interest
• The court may establish a new parent-time schedule (often longer summer blocks) and allocate transportation costs
• If relocation is found not to be in the child's best interest, the court may change custody rather than allow the move
