Utah Child Custody: A Parent's Guide

How child custody works in Utah, in plain English: legal and physical custody, the joint-legal-custody presumption, the 150-mile relocation rule, and child support.

Legal sources reviewed: August 9, 2026

In short: Utah presumes joint legal custody serves a child's best interest, rebuttable by domestic violence, special needs, or impractical distance between parents, but takes no position on joint versus sole physical custody, leaving that to the family's specific circumstances. Relocating 150 miles or more from the other parent's residence requires 60 days' advance written notice.

What Utah generally provides

Utah courts determine custody and parent-time under Utah Code § 30-3-10 based on the child's best interest. There's a rebuttable presumption favoring joint legal custody, but the statute establishes no preference either way for joint or sole physical custody, giving courts and families wide discretion to choose the arrangement that fits.

Important terminology

  • Legal custody: decision-making authority over the child's upbringing; presumptively joint under § 30-3-10, subject to rebuttal.
  • Physical custody: where the child lives and the actual parent-time schedule; no statutory preference for joint or sole.
  • Parent-time: Utah's term for the residential/visitation schedule.
  • Relocation: under § 30-3-37, moving 150 miles or more from the other parent's residence.

How custody works in Utah

Utah presumes joint legal custody is in a child's best interest, except where there's domestic violence in the home or in the child's presence, a parent's or child's special physical or mental needs making joint decision-making unreasonable, physical distance between the parents making joint decision-making impractical, or another factor the court finds relevant.

Physical custody, decided without a preset preference

Unlike legal custody, Utah's statute doesn't lean toward joint or sole physical custody. Courts weigh evidence of domestic violence, neglect, or abuse involving the child, a parent, or a household member, each parent's demonstrated understanding of and responsiveness to the child's developmental needs, and each parent's capacity to function as a parent, among other relevant considerations.

Parenting schedules

Once legal and physical custody are set, families commonly build the actual parent-time schedule around patterns like 2-2-3 or week on, week off. See what is a parenting plan for what a strong plan generally covers, how to choose a custody schedule for a general framework, and the custody schedule generator to build the actual calendar.

Moving with your child (relocation)

Utah Code § 30-3-37 defines "relocation" as moving 150 miles or more from the other parent's residence. The relocating parent must give at least 60 days' advance written notice, affirming that the existing parent-time provisions, or a schedule both parties have approved, will be followed, and that neither parent will interfere with the other's court-ordered or agreed parent-time. Either party, or the court on its own motion, can request a hearing to review the notice and parent-time schedule and make appropriate orders about parent-time and transportation costs. A parent who fails to give the required notice can be held in contempt of court. See moving to another state with shared custody for how relocation standards tend to work more broadly across states.

Common questions

How is child support calculated? Utah uses the income shares model under Utah Code Title 78B, Chapter 12 (recently reorganized under Title 81, Chapter 6, with the same underlying principles): both parents' gross monthly incomes are combined and referenced against the statutory child support tables, with each parent's obligation set proportionally, adjusted for the number of overnights in joint custody arrangements.

Can a custody order be changed later? Yes, generally on a showing of a substantial change in circumstances and that a modification serves the child's best interest.

What if my co-parent won't follow the parent-time schedule? You can file a motion for contempt or to enforce the order with the court. Courts can order makeup parent-time and, in serious or repeated cases, hold a parent in contempt.

Practical considerations

Because Utah treats legal and physical custody so differently, presuming joint legal custody while remaining neutral on physical custody, it's worth being clear about which one is actually being negotiated or contested at any given point, and discussing both directly with a Utah family law attorney. Whatever the order specifies, the operational part that follows it, keeping both households aligned on the same schedule, logging change requests instead of relying on memory, and keeping a record if an enforcement issue arises, is a separate, ongoing piece worth planning for.
