Utah Custody Laws: Joint Legal, Parent-Time, and Relocation

Utah custody laws divide parental authority into two separate categories — legal custody, which is the power to make major decisions about a child’s upbringing, and physical custody, which determines where the child lives. The state starts from the position that both parents should remain involved after a separation unless doing so would harm the child, and the rules apply whether the parents were ever married, once parentage is established. The governing statutes were recodified under Title 81 of the Utah Code effective September 1, 2024.

Legal Custody and Physical Custody

Legal custody covers the big decisions: education, healthcare, religious upbringing. Physical custody covers the day-to-day — which house the child sleeps in, and how often. The two operate independently. You can share legal custody while one parent has primary physical custody, and this is in fact the most common Utah arrangement.

Joint legal custody means both parents must consult each other and agree on significant decisions. Sole legal custody gives one parent full decision-making power without the other’s input. For physical custody, Utah draws a specific line: joint physical custody means the child spends at least 111 nights per year in each parent’s home.¹ Anything less, and one parent has sole physical custody while the other follows a parent-time schedule.

These labels matter because they shape what each parent can do without permission. A sole legal custodian can enroll the child in school or authorize surgery on their own; a joint legal custodian cannot.

The Presumption of Joint Legal Custody

Utah law begins with a rebuttable presumption that joint legal custody serves a child’s best interests. Under Utah Code 81-9-205, the court’s starting point is that both parents will share major decision-making authority.² A parent who wants sole legal custody has to overcome that presumption by a preponderance of the evidence.

The presumption does not apply when the court finds evidence of domestic violence, abuse, or neglect involving the child or a household member, special physical or mental health needs that make joint decision-making unreasonable, or geographic distance between the parents’ homes that makes joint decisions impractical.² In those circumstances, the court decides without any thumb on the scale.

A common misunderstanding: joint legal custody does not mean equal physical time. The statute specifically states that joint legal custody is not based on awarding equal or nearly equal periods of physical custody, because the child’s best interest often requires designating one home as the primary residence.² You can share full decision-making while the child lives primarily with one parent.

How a Judge Decides Custody

Every Utah custody decision turns on one question: what arrangement serves the child’s best interests? Under Utah Code 81-9-204, the court evaluates this by a preponderance of the evidence, weighing a list of statutory factors specific to each parent and the child.³

The court looks first at safety. Evidence of domestic violence, physical or sexual abuse involving the child or a household member, and whether a parent has intentionally exposed the child to pornography or harmful material are threshold concerns that can effectively disqualify a parent.³ Beyond safety, the court weighs whether a custody arrangement would endanger the child’s health or psychological well-being.

Assuming no disqualifying safety issues, the judge weighs a broader set of factors:

Each parent’s understanding of the child’s developmental needs and demonstrated capacity to function as a parent.
Which parent has been the child’s primary caregiver up to this point.
Each parent’s emotional health and moral character.
Whether drug abuse, excessive drinking, or similar issues impair a parent’s ability to care for the child.
The benefit of keeping siblings together.
The child’s bond with each parent, along with relationships with stepparents and extended family.
Each parent’s financial stability and responsibility.
Each parent’s willingness to support the child’s relationship with the other parent — the statute establishes that, absent evidence of real harm, it is in the child’s best interest to have frequent, meaningful, and continuing access to both parents.³

If a child is at least 14, the court gives added weight to the child’s stated preference about where to live. A younger child’s wishes may still be considered depending on maturity, but preference is never the single controlling factor, and judges will override a stated desire when long-term welfare calls for a different arrangement.¹

The Minimum Parent-Time Schedule

When parents cannot agree on a schedule, Utah Code 81-9-302 sets the floor for how much time a noncustodial parent receives with a child between the ages of five and eighteen.⁴ This is a minimum. Either parent can request more, but a court will not order less without justification.

The baseline for children ages five through eighteen includes:

One midweek evening, typically Wednesday from 5:30 p.m. to 8:30 p.m., though the noncustodial parent can choose a different weekday. If preferred, the visit can start when school lets out and run until 8:30 p.m.
Alternating weekends starting with the first weekend after the decree, from Friday at 6:00 p.m. to Sunday at 7:00 p.m. The noncustodial parent can elect to start at school dismissal on Friday.
A detailed holiday rotation that splits major holidays between parents on alternating odd and even years, covering everything from Martin Luther King Jr. Day and Presidents’ Day through Thanksgiving and Christmas.
Up to four weeks of summer parent-time, which may be consecutive. Two of those weeks are uninterrupted, meaning the custodial parent cannot insert a midweek visit.⁴

The custodial parent also gets two uninterrupted weeks during summer. For children under five, Utah provides a separate, more graduated schedule that typically starts with shorter daytime visits and builds toward overnights as the child grows older.

Parenting Plans

Any parent requesting joint legal or physical custody must file a parenting plan with the court. Utah Code 81-9-205 requires the plan to be filed alongside the initial petition or answer.² If the parents cannot agree, the court will impose one.

A workable plan covers the specifics that actually cause fights: which parent has the child on which holidays, how summer breaks are divided, pickup and drop-off logistics, and how transportation costs are split. It should spell out a dispute resolution process, such as requiring mediation before filing a motion. Forms are available on the Utah Courts website, or you can build the plan through MyPaperwork, the state’s online document preparation tool that replaced the former OCAP system.⁵

Two provisions worth asking for. First, a right of first refusal clause requiring a parent who has scheduled time to offer that time to the other parent before using a third-party babysitter when they cannot be there. Courts do not always add this on their own. Second, designate which parent has final decision-making authority on specific issues (education, healthcare, extracurriculars) when joint legal custodians cannot reach agreement. That tie-breaker prevents a disagreement from becoming a court filing.

Changing an Existing Custody Order

Custody orders can be modified, but the standard is deliberately high. Under Utah Code 81-9-208, a parent asking to change custody must show a substantial and material change in circumstances since the original order was entered, and that the proposed modification would actually improve the child’s situation.⁶ Dissatisfaction with the current schedule does not meet the standard. A parent’s serious substance abuse problem, a significant change in work schedule, or the child developing special needs that one household is better equipped to handle would.

The bar for adjusting parent-time only — rather than custody itself — is somewhat lower. You need to show simply a change in circumstances, without the “substantial and material” qualifier.⁶ One extra requirement applies to parents who currently share joint custody: both must first attempt their agreed dispute resolution process in good faith before filing a modification petition. Skipping that step can get the petition dismissed.

Moving Away: The 150-Mile Rule

If you have custody and want to move 150 miles or more from the other parent’s home, Utah Code 81-9-209 requires written notice to the other parent at least 60 days before the planned move.⁷ The notice has to confirm you will follow the applicable parent-time schedule or a schedule both parents approve.

Either parent, or the court on its own, can request a hearing to review the relocation and adjust parent-time and transportation costs. The court evaluates whether the move serves the child’s best interests. If the court decides the relocation is not in the child’s best interest and the custodial parent moves anyway, the court can change custody entirely.⁷ A parent who fails to provide the required 60-day notice can be held in contempt.

When Parents Live in Different States

If you and the other parent live in different states, the first question is not what the custody arrangement should be. It is which state has the power to decide. Utah has adopted the Uniform Child Custody Jurisdiction and Enforcement Act, now codified under Title 81, Chapter 11.⁸

The UCCJEA gives priority to the child’s “home state,” defined as the state where the child has lived with a parent for at least six consecutive months immediately before the custody case is filed. For infants younger than six months, the home state is wherever the child has lived since birth.⁸ Temporary absences, like a summer visit to the other parent, do not interrupt that six-month count.

If a child recently moved to Utah, the previous home state may still have jurisdiction when a parent remains there. Utah courts cannot make an initial custody determination unless Utah qualifies as the home state, or the home state has declined jurisdiction. The rule prevents a parent from moving across state lines and immediately filing in a court they consider more favorable.

A Note on the Title 30 to Title 81 Change

If you are reading older articles, court documents, or decrees, you may see references to Title 30 of the Utah Code (sections like 30-3-10 through 30-3-35). Utah enacted a domestic relations recodification that moved family law provisions to Title 81, effective September 1, 2024, with additional changes in 2025. The substantive rules are largely the same, but the section numbers changed. Current court forms and filings reference Title 81, so anything you prepare should use the new numbering.
