Child Support in Prince William County, Virginia: How Much Will You Owe?

Quick answer: it depends on both parents' incomes, how many children you have, and the parenting schedule. The calculator on this page turns those numbers into a real guideline estimate in about a minute. It is an educational estimate, not legal advice, and the judge always sets the final amount. FamilyCourtHelp.com is a self-help resource, not a law firm.

How much child support will you owe in Prince William County, Virginia? There is no flat rate. Virginia uses one statewide formula, and the number moves with each parent's income, the number of children, and how many overnights the kids spend with each of you. This page walks through how the math works, and you can run your own estimate right here.

Virginia follows the Income Shares model under Va. Code § 20-108.2. The court combines both parents' monthly gross incomes, looks up the basic support obligation on the state's guideline schedule for that income level and number of children, then prorates the obligation between the parents according to each parent's percentage share of the combined income.

What counts as income? Virginia runs the formula on gross income, meaning income before taxes come out. Gross income from any source including wages, self-employment, severance, pensions, retirement, Social Security, workers' compensation, unemployment, and recurring gifts.

Parenting time matters directly in Virginia: the number of overnights each parent has changes the math itself. Virginia uses a shared-custody formula that kicks in only when each parent has at least 90 overnights with the child per year. Once both parents cross that 90 overnight line, the guideline recalculates support to reflect the time each parent provides the home, food, and daily care. Below 90 overnights for one parent, the standard Income Shares calculation applies without a shared-care adjustment. This on-page calculator gives an estimate, and the official Virginia worksheet controls the final number.

When does it end? Virginia child support generally ends at age 18 but continues to age 19 if the child is a full-time high school student, not self-supporting, and living with a parent. Continuing support for disabled adult children is available.

Can the amount change later? File a motion in juvenile and domestic relations or circuit court, or request review through DCSE. A material change in circumstances supports modification.

If payments fall behind, Virginia has real enforcement tools. Virginia DCSE enforces through immediate income withholding, tax intercept, license suspension, lien filings, credit reporting, and contempt referrals.

Child support cases arising in Prince William County are generally handled through Virginia's Circuit Court, and Virginia Division of Child Support Enforcement (Department of Social Services) runs the state's child support services program. Offices, forms, and local practice can vary from county to county, so confirm the current details with your local court or the agency.
