How to Modify a Utah Custody Order
Short answer: To modify a Utah custody order, you generally have to show there's been a material and substantial change in circumstances since the existing order was entered, and that modifying custody would actually improve the situation and serve the child's best interests. Wanting a different arrangement, on its own, generally isn't enough.
Who this guide is for
Parents with an existing Utah custody order who believe circumstances have changed enough to justify modifying it.
The two-part standard
Utah courts generally apply a two-step analysis:
- Has there been a material and substantial change in circumstances since the current order was entered?
- Would modifying custody be an improvement and in the child's best interests?
Both parts generally need to be met — a real change in circumstances alone doesn't automatically mean modification is warranted if it wouldn't actually improve the situation for the child.
Examples of what can count as a material and substantial change
- A parent's remarriage
- A parent (or the child) moving to a new community
- The child needing to change schools
- A parent living with, or giving access to, someone convicted of certain serious crimes
These are examples, not an exhaustive list — whether your specific situation qualifies depends on the facts, and this is genuinely a judgment call courts make case by case.
What generally does NOT qualify
Simply preferring a different arrangement, disagreements about parenting style that don't rise to a substantial change, or a temporary, short-term situation generally aren't enough on their own to meet this standard. Utah's modification standard exists specifically to provide stability for children — courts are intentionally cautious about revisiting custody arrangements without a real, substantial change behind the request.
The process
- File a petition to modify with the court that has jurisdiction over the existing order.
- Serve the other parent, who has the opportunity to respond.
- Present evidence of the material and substantial change, and why modification serves the child's best interests.
- The court decides — through agreement between the parties, mediation, or a contested hearing if necessary.
If both parents agree
If you and the other parent agree on a modification, the process is generally more straightforward — an agreed modification can often be submitted to the court for approval without a contested hearing, though it still needs to go through the court to become a legally enforceable order (an informal agreement between parents, without court approval, doesn't replace the actual legal order).
Frequently asked questions
How long does a custody order have to be in place before I can request a modification? There's no fixed waiting period — the question is whether a material and substantial change has occurred, which can happen quickly or take years.
Can I modify custody without going to court if we both agree? Even an agreed change generally needs to be formalized through the court to be legally binding and enforceable — an informal agreement alone leaves the original order technically still in effect.
What's the difference between modifying custody and modifying parent-time? Custody generally refers to legal and physical custody designations; parent-time refers to the specific schedule. See How to Modify Utah Parent-Time if it's the schedule itself, not the underlying custody arrangement, that needs to change.
