FORMULA How North Dakota Calculates Child Support
North Dakota Century Code Section 14-09-09.7 governs child support. North Dakota’s varying percentage model applies different rates at different income levels.
AGE When Does Child Support End in North Dakota?
Child support in North Dakota ends when the child turns 18 — or high school graduation, whichever is later. Support also ends upon the child’s death, marriage or emancipation. Important: In most cases support does not stop automatically — you need a court order. Stopping payments without a court order creates arrears even after the child reaches the cutoff age.
INTEREST Arrears Interest in North Dakota
North Dakota charges 6% annual interest on unpaid child support arrears. There is generally no statute of limitations on child support debt.
ENFORCEMENT North Dakota Child Support Enforcement
North Dakota has broad enforcement powers including wage garnishment, tax refund interception, driver’s license suspension, professional license suspension, passport denial, and credit bureau reporting. Criminal charges may apply for significant or long-term non-payment.
MODIFY Modifying Child Support in North Dakota
Child support can be modified in North Dakota when there is a material and substantial change in circumstances — typically a significant income change, job loss, new children from another relationship, or change in custody. Most states also allow a periodic review every 3 years. File a petition with the court — private agreements to change support are not legally enforceable.
