Wyoming Child Support: A Parent's Guide

Q: How do I request a modification in Wyoming?

Wyoming presumes a change is material if recalculating support produces an amount differing by 20% or more from the existing order. Common grounds include significant income changes, job loss, custody modifications, or changes in the child's needs.

Q: Is there a review available without proving a change?

Yes. Every three years, upon request of either parent or the department, the court reviews and adjusts the order according to current guidelines, without requiring a showing of changed circumstances.

Q: How is child support enforced in Wyoming?

The Wyoming Child Support Program provides free enforcement services including income withholding, tax refund interception, license suspension (driver's, professional, and recreational), financial account seizure, credit reporting, passport denial, lottery winnings interception, and property liens. Wage garnishment can reach up to 50-65% of income.

In short: Wyoming presumes a 20%+ difference from a fresh calculation is a material change supporting modification, and the state's Child Support Program will pursue that modification at no cost if you qualify. A 3-year review is available without proving anything, and Wyoming's free enforcement services span income withholding through passport denial.

What Wyoming generally provides

Under Wyo. Stat. § 20-2-304, Wyoming uses the income shares model: both parents' net incomes are combined to determine a total support obligation, then divided proportionally by each parent's share of that combined income.

Important terminology

20% presumption: Wyoming's threshold for presuming a material change in circumstances supports a modification.
DIVCP-13: the Child Support Computation Form required for a modification filing.
Free program-initiated modification: Wyoming's no-cost path, where the Child Support Program petitions the court on a qualifying parent's behalf.

How the calculation works

Combining net income and dividing proportionally

Both parents' net incomes are combined to reach a total support obligation, then divided proportionally based on each parent's share of that combined figure, standard income-shares logic applied through Wyoming's own guideline schedule.

Requesting or defending a modification

Wyoming presumes a change is material if recalculating support under current guidelines would produce an amount differing by 20% or more from the existing order. Common grounds include significant income changes, job loss, custody modifications, or changes in the child's needs. Every three years, upon request of either parent or the department, the court reviews and adjusts the order according to current guidelines, without requiring a showing of changed circumstances. To request a modification, file with the district court that issued the original order, provide updated financial documentation, and complete a new Child Support Computation Form (DIVCP-13). Alternatively, contact the Wyoming Child Support Program at (307) 777-5300: the program will gather both parents' income information and, if the current order differs from the guidelines by at least 20%, can petition the court on your behalf at no cost. See the child support calculator and guideline finder for jurisdiction-specific calculation sources and guidance.

How enforcement works

The Wyoming Child Support Program provides free enforcement services, including income withholding, tax refund interception, license suspension (driver's, professional, and recreational), financial account seizure, credit reporting, passport denial, lottery winnings interception, and property liens. Wage garnishment can reach up to 50-65% of income, depending on the paying parent's other support obligations and arrears status.

Common questions

Do I need to hire an attorney to get a modification? Not necessarily, if your order differs from the current guidelines by at least 20%, the Wyoming Child Support Program can petition the court on your behalf at no cost.

Do I need to show my circumstances changed if it's been 3 years? No, the guaranteed three-year review doesn't require proving anything specific changed, either parent or the department can simply request it.

What if my co-parent isn't paying? Contact the Wyoming Child Support Program at (307) 777-5300, which provides free enforcement services across the full range of tools, from wage withholding to passport denial.

Practical considerations

Because Wyoming's Child Support Program offers a genuinely free path for both modification (at the 20% threshold) and enforcement, it's worth contacting them directly before assuming you need to hire an attorney or navigate the district court process alone, especially for a straightforward, guideline-based adjustment. For the custody and best-interest-factors framework that intersects with the parenting-time side of these calculations, see the Wyoming custody guide.
