Child Support in North Dakota: 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.

Wondering how much child support you will owe or receive in North Dakota? The state uses one formula everywhere, so the same math applies in every county. This page explains how it works, lets you run a live estimate, and links to a dedicated page for each county at the bottom.

North Dakota uses a Varying Percentage of Income model under N.D. Admin. Code § 75-02-04.1. The percentage applied to the obligor's income changes with income brackets and number of children, with a statutory cap on the income subject to the standard percentages.

What counts as income? North Dakota runs the formula on net income, meaning income after taxes come out. Net monthly income, gross income from all sources reduced by federal and state taxes, FICA, mandatory retirement, mandatory union dues, and existing child support orders.

Parenting time matters directly in North Dakota: the number of overnights each parent has changes the math itself. North Dakota's standard calculation applies a percentage to the paying parent's net income and does not reduce the amount for ordinary visitation. Parenting time only changes the number when care is closely split. Under N.D. Admin. Code section 75-02-04.1, a separate equal-care worksheet is used when each parent has the child at least 175 overnights per year, which can lower the obligation. Below that threshold, more overnights do not automatically cut the support figure.

When does it end? North Dakota child support generally ends at age 18 but extends to age 19 if the child is still attending high school. Continuing support for disabled adult children is available.

Can the amount change later? File a motion in district court or request review through North Dakota Child Support. A 15% variance supports modification.

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

Child support cases in North Dakota are generally handled through the state's District Court, and North Dakota Child Support Division (Department of Health and Human Services) runs the state's child support services program. Forms and local practice can vary, so confirm the current details with your local court or the agency.
