Utah child support orders can be modified when financial circumstances change significantly. Under Utah Code § 81-6-212, a parent may request modification if the proposed support amount differs from the current order by at least 10% (after 3 years) or 15% (within 3 years). The filing fee for a Petition to Modify is $100 as of March 2026, and the Office of Recovery Services (ORS) offers an administrative review process that typically completes within 180 days. Utah courts use the Income Shares Model to calculate support, combining both parents' adjusted gross incomes and applying the base combined child support obligation table under Utah Code § 81-6-304.

Understanding Child Support Modification in Utah
Utah law permits child support modification Utah requests under two primary circumstances: a substantial change in circumstances or the passage of three years since the last order. Under Utah Code § 81-6-212, parents can change child support when the recalculated amount differs from the current order by at least 10% (if 3 or more years have passed) or 15% (if less than 3 years have passed). The change in circumstances cannot be temporary, meaning it must be expected to last 12 months or longer.
The modification process serves to ensure child support obligations remain fair and appropriate as family circumstances evolve. Common triggers for seeking modification include job loss resulting in a 30% or greater income reduction, significant salary increases, changes in custody arrangements affecting overnight visits, medical conditions requiring additional care expenses, or the emancipation of a child on the support order. Utah courts evaluate each request based on the child's best interests while applying the state's child support guidelines uniformly.
The Two Modification Methods: Motion vs. Petition
Utah offers two distinct legal procedures for requesting a change child support order: a Motion to Adjust and a Petition to Modify. A Motion to Adjust is the simpler and faster option with no filing fee, but it can only be used when the order has not been modified in three or more years and the recalculated support amount differs by at least 10%. This streamlined process does not require proving a substantial change in circumstances.
A Petition to Modify costs $100 to file and requires more extensive documentation, but it can be used in any situation where modification is warranted. Parents must use a petition when seeking to increase child support or reduce child support within three years of the last order, when the proposed amount would deviate from the guidelines, or when other circumstances prevent using the motion process. The petition must be filed in the same court that issued the original divorce decree or custody order, using the same case number.
Comparison: Motion to Adjust vs. Petition to Modify
| Factor | Motion to Adjust | Petition to Modify |
|---|---|---|
| Filing Fee | $0 | $100 |
| Time Since Last Order | 3+ years required | Any time |
| Percentage Threshold | 10% | 15% (under 3 years) |
| Change in Circumstances | Not required | Required (under 3 years) |
| Complexity | Simpler, faster | More documentation |
| Deviation from Guidelines | Must follow guidelines | Can request deviation |
Qualifying for a Child Support Modification
Utah courts recognize specific circumstances that justify a decrease child support or increase child support request. A material change in circumstances exists when the difference between the existing order and the recalculated amount under current guidelines exceeds the applicable threshold. The change must be substantial, permanent (lasting more than 12 months), and not the result of a parent voluntarily reducing their income to avoid obligations.
Income changes represent the most common basis for modification requests. If either parent experiences a 30% or greater change in income, this typically qualifies as a substantial change. Job loss, disability, retirement, significant promotions, or starting a new business can all justify recalculating support. However, Utah law explicitly prohibits modifications when a parent voluntarily quits their job or accepts lower-paying work specifically to reduce their support obligation.
Circumstances That Qualify for Modification
- Permanent income changes of 30% or more for either parent
- Job loss, disability, or long-term illness affecting earning capacity
- Changes in custody arrangements affecting overnight parenting time
- Child developing medical conditions requiring additional expenses
- Emancipation of a child on the existing support order
- Incarceration exceeding 180 days (triggers automatic ORS review)
- Addition of new children to either parent's household
- Changes in work-related childcare expenses
Circumstances That Do Not Qualify
- Voluntary income reduction to avoid support payments
- Temporary job changes lasting less than 12 months
- Interference with visitation by one parent
- Changes to the base combined child support obligation table alone
- General cost-of-living increases without corresponding income changes
The Office of Recovery Services (ORS) Administrative Process
Utah provides an administrative alternative to court proceedings through the Office of Recovery Services. The ORS can review and adjust child support amounts and medical support provisions without requiring parents to navigate the court system independently. This process, known as review and adjustment, can be initiated by either the parent receiving support or the parent paying support, and ORS completes most reviews within 180 days.
To request an ORS review, parents must submit a written request using form OM50 (Review and Adjust Pre-Review Packet), available at ors.utah.gov. Once ORS receives the request, both parents receive a Financial Statement to complete along with verification of yearly gross income. The agency applies the same modification thresholds as the courts: 10% difference if the order has not changed in three years, or 15% difference plus a change in circumstances if modified within the past three years.
ORS works with the Utah Attorney General's Office to petition the court when necessary, representing both parties throughout the process. However, ORS cannot modify custody or visitation arrangements, only the financial aspects of child support orders. The agency also conducts automatic reviews when it learns a paying parent will be incarcerated for more than 180 days, potentially lowering support during incarceration and adjusting it upon release.
Calculating the New Support Amount
Utah uses the Income Shares Model to calculate child support, which combines both parents' adjusted gross monthly incomes and divides the support obligation proportionally. The base combined child support obligation table under Utah Code § 81-6-304 determines the presumptive support amount based on combined income and number of children. For example, a family with combined monthly income of $10,000 and two children has a base obligation of approximately $1,848 per month before adjustments.
The official Utah Child Support Calculator maintained by ORS at orscsc.dhs.utah.gov applies all applicable adjustments automatically. These adjustments include credits for overnight parenting time (joint physical custody arrangements), work-related childcare costs, health insurance premiums for the children, and extraordinary medical expenses. The minimum child support order in Utah is $30 per month, and the guidelines cover combined incomes up to $100,000 per month.
Income Considerations for Modification
| Income Factor | Treatment in Calculation |
|---|---|
| Gross wages and salary | Included at full value |
| Self-employment income | Net income after legitimate business expenses |
| Overtime and bonuses | Included if regular and consistent |
| Imputed income | Assigned if voluntarily unemployed/underemployed |
| New spouse's income | Generally not included |
| Social Security benefits | May be credited toward support |
| Low income ($650-$1,050/month) | Special low-income table applies |
| Very low income (under $649/month) | Case-by-case determination, minimum $30/month |
Filing Your Modification Request
Parents seeking a child support modification Utah order must file in the same court that issued the original divorce decree or custody order, using the same case number. The Utah Courts website at utcourts.gov provides all necessary forms through its self-help section, and parents can file online through MyCase. The filing fee for a Petition to Modify is $100 as of March 2026, though fee waivers are available for those who qualify based on income.
After filing, the petitioning parent must serve the other party with the Petition to Modify, summons, and supporting documents within 120 days. Service must comply with Utah rules of civil procedure, typically requiring personal service or service by mail with acknowledgment. The responding parent has 21 days to file a response if served within Utah, or 30 days if served outside Utah. Failure to respond may result in a default judgment granting the requested modification.
Required Documents for Filing
- Completed Petition to Modify Child Support form
- Current child support worksheet with updated income information
- Financial declaration showing all income sources
- Verification of income (pay stubs, tax returns, employment records)
- Documentation of changed circumstances (medical records, termination letters)
- Copy of the existing child support order
- Proposed parenting time schedule (if custody changes requested)
- Proof of childcare expenses and health insurance costs
The Court Hearing Process
After both parties have filed their documents, the court may schedule mediation before setting a hearing. Utah courts encourage parents to reach agreement through mediation whenever possible, as this reduces costs and processing time. If mediation fails or is not required, the court schedules a hearing where both parties present evidence supporting their positions on the proposed modification.
At the hearing, the judge evaluates whether a substantial change in circumstances has occurred (if less than three years since the last order) and whether the proposed modification meets the 10% or 15% threshold. The court takes into account the child's best interests while applying Utah's child support guidelines. Under Utah Code § 81-6-204, judges retain discretion to deviate from the guidelines when strict application would be unjust, inequitable, or inappropriate, though such deviations are rare and typically increase rather than decrease support.
New Requirements Effective July 2026
Beginning July 1, 2026, Utah law requires courts and administrative agencies to include a provision in all child support orders requiring the obligor parent to pay a reasonable ongoing expense for childcare to assist with childcare expenses. This new requirement applies to both initial child support orders and modifications, potentially affecting the calculation of support amounts for families with young children requiring daycare or after-school care.
This change reflects Utah's recognition that childcare costs represent a significant financial burden for custodial parents. When seeking modification after July 1, 2026, parents should be prepared to document current childcare expenses and include these costs in their support calculations. The requirement ensures that childcare expenses are addressed consistently in all Utah child support orders rather than being treated as an optional add-on.
Timeline and Processing Expectations
The duration of a child support modification case varies based on the method used and whether the parties reach agreement. Administrative reviews through ORS typically complete within 180 days, though court involvement can extend this timeline. Court-filed petitions may resolve within 60-90 days if uncontested, but contested modifications requiring hearings often take 4-6 months or longer depending on court schedules.
Once a modification is granted, the new support amount applies prospectively from the date specified in the order. Utah generally does not allow retroactive modifications beyond the filing date, making prompt action important when circumstances change. Support obligations continue under the existing order until a court or ORS issues a modified order, so parents should continue making payments at the current level while the modification is pending.
Typical Timeline by Method
| Method | Uncontested | Contested |
|---|---|---|
| ORS Administrative Review | 90-180 days | 180+ days |
| Motion to Adjust | 30-60 days | 60-90 days |
| Petition to Modify | 60-90 days | 4-6 months |
Frequently Asked Questions
How much does it cost to modify child support in Utah?
The filing fee for a Petition to Modify Child Support in Utah is $100 as of March 2026. A Motion to Adjust has no filing fee but can only be used when three or more years have passed since the last order. Fee waivers are available for parents who demonstrate financial hardship. Additional costs may include attorney fees ($200-400 per hour), process server fees ($50-100), and document preparation expenses.
What percentage change is needed to modify child support in Utah?
Utah requires either a 10% or 15% difference between the current order and the recalculated support amount. If three or more years have passed since the order was entered or last modified, only a 10% difference is required with no showing of changed circumstances. If less than three years have passed, you must prove a substantial change in circumstances and demonstrate at least a 15% difference.
Can I reduce child support if I lost my job in Utah?
Yes, job loss can qualify as a substantial change in circumstances justifying a decrease child support request in Utah. You should file for modification promptly after losing employment, as the new amount typically applies from the filing date, not retroactively. However, Utah courts may impute income if they determine you are voluntarily unemployed or underemployed. Documentation of your job search efforts is essential.
How long does a Utah child support modification take?
ORS administrative reviews typically complete within 180 days. Court petitions vary widely: uncontested modifications may resolve in 60-90 days, while contested cases requiring hearings often take 4-6 months. Using a Motion to Adjust (when eligible) is generally faster than filing a Petition to Modify. Delays can occur if income verification is incomplete or if the other parent fails to respond.
Can ORS modify my child support without going to court?
Yes, the Office of Recovery Services can review and adjust child support administratively without requiring you to file in court. To initiate this process, submit a written request using form OM50 along with income documentation. ORS can only modify financial aspects of support, not custody or visitation. If disputes arise that ORS cannot resolve administratively, the case may still require court involvement.
What if my ex voluntarily quit their job to reduce support?
Utah courts do not approve modifications when a parent voluntarily quits or takes lower-paying work specifically to avoid child support obligations. The court may impute income based on the parent's earning capacity, work history, education, and available job opportunities. If you believe your ex reduced their income intentionally, present evidence of their qualifications, job market opportunities, and the timing of their employment change.
Does Utah allow retroactive child support modifications?
Utah generally limits modifications to prospective changes from the filing date forward. Courts do not typically make retroactive adjustments to support that was due before the modification petition was filed. This makes timely filing crucial when circumstances change. Continue paying the current support amount until a new order is issued, as failure to pay can result in enforcement actions.
How does joint custody affect child support modification in Utah?
Utah calculates child support partly based on overnight parenting time. In joint physical custody arrangements, the support obligation adjusts based on the number of overnights each parent has. If custody changes significantly, either increasing or decreasing one parent's time, this can justify a modification request. A change from sole custody to joint custody, or vice versa, typically qualifies as a substantial change in circumstances.
What income is included when calculating modified support in Utah?
Utah includes gross income from all sources: wages, salaries, commissions, bonuses, overtime, self-employment income, rental income, dividends, Social Security benefits, and veterans' benefits. Income from a new spouse is generally not included. For self-employed parents, the court uses net income after legitimate business expenses. If a parent is voluntarily unemployed or underemployed, the court may impute income based on earning capacity.
Can I modify child support if my income increased?
Yes, either parent can request modification when the paying parent's income increases substantially. Under Utah law, a 30% income change typically qualifies as a material change in circumstances. The custodial parent can petition to increase child support to reflect the higher income. The modification must still meet the 10% threshold (after 3 years) or 15% threshold (under 3 years) between the current and proposed support amounts.
