Q: How do I request a modification in North Dakota?

Parents with orders at least 12 months old may request modification without demonstrating any change in circumstances, simply asking the court to adjust support to conform with current guidelines. Orders less than 12 months old require proving a material change in circumstances, typically an income change of at least $50 per month.

In short: North Dakota calculates support as a percentage of the noncustodial parent's net income, updated for January 1, 2026. An order at least 12 months old can be modified without proving anything, simply to match current guidelines, while a newer order needs a real change, generally at least $50/month. Enforcement escalates with arrears thresholds: tax refund intercepts at $500, license suspension at $5,000.

What North Dakota generally provides

Under N.D. Admin. Code 75-02-04.1, North Dakota's guidelines, updated January 1, 2026, calculate support as a percentage of the obligor's net income: 14% for one child, 20% for two, 22% for three, 24% for four, and 27% for five or more.

Important terminology

Percentage-of-net-income model: North Dakota's calculation approach, based on the noncustodial parent's own income rather than combined parental income.
12-month no-proof modification: the right to seek a modification without demonstrating a specific change, once an order is at least a year old.
Arrears escalation thresholds: North Dakota's specific dollar triggers for tax refund intercepts ($500) and license suspension ($5,000).

How the calculation works

A percentage tied to net income and the number of children

North Dakota applies its percentages directly to the noncustodial parent's net income, similar in structure to states like Texas and Mississippi that calculate from one parent's income rather than a combined figure: 14% for one child up through 27% for five or more, per the guidelines updated January 1, 2026.

Requesting or defending a modification

Parents with orders at least 12 months old may request a modification without demonstrating any change in circumstances at all, simply asking the court to adjust support to conform with current guidelines. Orders less than 12 months old require proving a material change in circumstances, typically an income change of at least $50 per month to justify early modification. The filing fee is $160 as of July 1, 2025. The North Dakota Child Support Division also automatically reviews orders every 36 months for cases receiving full enforcement services, and parents can pursue either an administrative review through the Division or file a motion directly with the district court that issued the original order. See the child support calculator and guideline finder for jurisdiction-specific calculation sources and guidance.

How enforcement works

Income withholding is North Dakota's primary enforcement method, collecting roughly 70% of payments statewide. Beyond withholding, federal and state tax refund intercepts apply once arrears exceed $500, and license suspensions (driver's, professional, and recreational) apply once arrears exceed $5,000, giving North Dakota's enforcement a clear, escalating structure tied to specific dollar thresholds.

Common questions

Do I need to prove anything if my order is over a year old? No, once an order is at least 12 months old, you can request a modification simply to match current guidelines, without needing to show your own circumstances changed.

How much in arrears triggers tax refund interception versus license suspension? Tax refund intercepts start at $500 in arrears, a relatively low bar, while license suspension doesn't kick in until arrears reach $5,000, a meaningfully higher threshold.

What if my co-parent isn't paying? Contact the North Dakota Child Support Division, which handles income withholding and the escalating enforcement tools tied to specific arrears thresholds.

Practical considerations

Because North Dakota's tax refund intercept threshold ($500) is far lower than its license suspension threshold ($5,000), don't assume enforcement waits until arrears become severe, meaningful consequences can start relatively early in the delinquency.
