Modify a Utah Custody & Child Support Order
When Utah lets you change an order, the forms you need, and how to prove a material and substantial change
Utah Law Explained gives you a Utah-focused answer first, then the exact steps, forms, timelines, and common mistakes. You can modify a custody or child support order in Utah, but only if you meet the legal standard of showing a material and substantial change in circumstances.
Why does this matter? Life changes — income shifts, kids grow, schedules move. Utah courts recognize this, but they won’t reopen an order without proper grounds and process. By the end, you’ll know how to approach a modification with confidence.
Material & Substantial Change: What Counts
Before you file, you must show there’s been a meaningful change since the last order. Minor inconveniences or disagreements aren’t enough.
Income or Employment
Significant change in income or job status can justify modifying support.
Relocation
A move that affects parenting time or school routines may qualify.
Child’s Needs
New health, therapy, or educational needs impacting custody/support.
Plan Interference
Ongoing interference with the current plan or missed parenting time.
Choose the Right Forms & File
Pick the correct petition, complete it carefully, and file in the proper Utah district court. Many cases stall over incomplete paperwork.
After filing, you must properly serve the other parent using Utah-approved service methods, not regular mail.
