North Dakota Child Support FAQ

How is child support calculated in North Dakota?

North Dakota applies fixed percentages of the paying parent’s net (after-tax) income under N.D. Admin. Code § 75-02-04.1-10. Both parents’ incomes are combined, a basic obligation is taken from the state’s official schedule, and each parent pays in proportion to their share of combined income.

Does North Dakota use gross or net income for child support?

North Dakota calculates support on net (after-tax) income as defined in N.D. Admin. Code § 75-02-04.1-10. Obligor-only schedule: the table applies to the paying parent’s monthly net income ($900-$25,000; $800 or less presumes $0); the “$25,000 or more” row is the statutory top.

Can a North Dakota court order more or less than the guideline amount?

Yes. The guideline amount under N.D. Admin. Code § 75-02-04.1-10 is presumptive, not absolute - courts may deviate with written findings for factors like extraordinary medical or educational needs, other children supported, or very high income beyond the guideline range.

How do I apply for or modify child support in North Dakota?

Apply through the North Dakota child support agency or the family court in your county. Existing orders can be modified on a substantial change in circumstances - typically a significant income change, job loss, or a change in custody.
