North Dakota child support payments typically range from $200 to $400 per month per child, calculated using the percentage-of-income model under N.D. Admin. Code § 75-02-04.1. The state bases support obligations primarily on the paying parent's net income rather than both parents' combined earnings, making North Dakota's approach distinct from the income-shares model used by most states. For a parent earning $4,000 monthly net income with two children, the presumptive support obligation is approximately $1,131 per month under the 2026 guidelines.

How North Dakota Calculates Child Support in 2026
North Dakota calculates child support using a graduated percentage schedule applied to the obligor's monthly net income under N.D. Admin. Code § 75-02-04.1-10, with the effective percentage decreasing as income rises. The calculation begins with the paying parent's gross income, subtracts allowable deductions to determine net income, and then applies the guidelines schedule based on the number of children. A parent earning $2,000 monthly net income with one child would pay approximately $500 per month (25% effective rate), while a parent earning $25,000 monthly net income with one child pays $3,500 (14% effective rate at the cap).
The North Dakota child support guidelines schedule operates as a lookup table where courts identify the obligor's monthly net income row and read across to the column matching the number of children. This dollar amount becomes the presumptive monthly child support obligation unless a party demonstrates that deviation is appropriate under NDAC § 75-02-04.1-09. The custodial parent's income does not factor into the base calculation, distinguishing North Dakota from the 41 states using the income-shares model.
Understanding Net Income for Child Support
Net income under NDAC § 75-02-04.1-01(5) equals gross income minus mandatory deductions including federal and state income taxes, FICA contributions, mandatory retirement contributions, health insurance premiums, union dues, and prior child support obligations for other children. Gross income encompasses wages, overtime, commissions, bonuses, severance pay, pensions, interest, dividends, social security benefits, workers' compensation benefits, unemployment insurance benefits, and any other income source exceeding nominal amounts.
The self-support allowance protects approximately $1,255 per month (based on federal poverty guidelines) before applying child support percentages. This Melson formula component ensures each parent retains sufficient income to meet basic personal needs, with only income above this threshold available for child support calculations. A parent earning $3,000 monthly gross with $500 in deductions has $2,500 net income, minus $1,255 self-support equals $1,245 available for child support obligations.
Sample Child Support Calculations for North Dakota
Understanding how much child support costs in North Dakota requires examining real-world scenarios using the N.D. Admin. Code Chapter 75-02-04.1 guidelines. These examples demonstrate how the percentage-of-income model produces different results based on income levels and family size. The North Dakota Department of Health and Human Services provides an official calculator that incorporates January 1, 2026 tax adjustments for accurate estimates.
Example 1: One Child, Moderate Income
A noncustodial parent earning $4,000 monthly gross income with $800 in mandatory deductions has $3,200 monthly net income. After subtracting the $1,255 self-support allowance, $1,945 remains available for child support. Under the guidelines schedule, the presumptive monthly obligation for one child at this income level is approximately $640, representing a 20% effective rate of net income.
Example 2: Two Children, Higher Income
When Robert earns $4,000 monthly adjusted income and Mary earns $2,400 monthly adjusted income with two children, Robert pays $1,131 monthly in child support to Mary when he has fewer than 101 overnights annually. The guidelines schedule accounts for the additional costs of raising two children by increasing the base obligation approximately 25-30% above the one-child amount at comparable income levels.
Example 3: Equal Parenting Time (50/50 Custody)
For equal residential responsibility arrangements where each parent has 180 or more overnights annually, North Dakota calculates each parent's obligation separately and offsets the amounts. If Parent A owes $800 based on their income and Parent B owes $500 based on their income, Parent A pays Parent B $300 monthly (the difference between obligations). This offset approach ensures the higher-earning parent contributes more while recognizing both parents' substantial caregiving time.
Deviation Factors: When Courts Adjust Child Support
North Dakota courts may deviate from the presumptive guidelines amount when specific factors make the standard calculation inappropriate, provided deviation serves the child's best interests under N.D.C.C. § 14-09-09.7. The court must document findings supporting any deviation, and adjustments typically range from 10-40% above or below the guidelines amount depending on circumstances. Common deviation factors include extraordinary medical expenses, special educational needs, significant travel costs for parenting time, and disparate standards of living between households.
Medical Expense Deviations
Significant ongoing medical costs exceeding typical healthcare expenses constitute a recognized deviation factor under NDAC § 75-02-04.1-09. A child with chronic illness requiring $500 monthly in specialized treatments not covered by insurance may justify increasing support to cover these extraordinary costs. Courts examine the actual out-of-pocket expenses, insurance coverage limitations, and whether the standard support amount adequately addresses the child's documented medical needs.
Educational Expense Deviations
Private school tuition, special education services, tutoring for learning disabilities, or extracurricular activities essential to the child's development may warrant deviation. Courts consider whether both parents historically agreed to these expenses, the child's established educational trajectory, and each parent's ability to contribute beyond the base obligation. A child enrolled in $15,000 annual private school since kindergarten presents stronger deviation grounds than a proposed new enrollment following divorce.
Imputed Income: Voluntary Unemployment and Underemployment
North Dakota courts impute income to voluntarily unemployed or underemployed parents under the guidelines when actual earnings do not reflect earning capacity. The guidelines were amended in 1991 to specifically include "income imputed based upon earning capacity" within the gross income definition under NDAC § 75-02-04.1-01. A parent earning $25,000 annually despite credentials supporting $60,000 earnings may have the higher amount imputed for support calculations.
Courts calculate imputed income using one of three methods specified in the administrative code: (a) 167 times the hourly federal minimum wage, equaling approximately $1,213 monthly at $7.25 minimum wage; (b) six-tenths of prevailing gross monthly earnings in the community for persons with similar work history and occupational qualifications; or (c) an amount consistent with the obligor's prior earning history. A licensed electrician working part-time retail would likely have income imputed based on electrical trade wages rather than actual retail earnings.
Job Loss and Child Support Obligations
Job loss constitutes a material change in circumstances justifying a modification motion under N.D.C.C. § 14-09-08.1, even if the current order is less than one year old. However, support is not automatically reduced upon job loss, and arrears continue accruing at the original amount until a court issues a modified order. The obligor should immediately file a modification motion ($160 filing fee) or contact the North Dakota Child Support Division for administrative review to avoid accumulating unmanageable arrears.
Courts distinguish between involuntary and voluntary job loss when determining whether to impute income. A parent terminated during company-wide layoffs faces different treatment than a parent who quit to avoid support obligations. Documentation proving the job loss circumstances, active job search efforts, and applications matching qualifications strengthens arguments against imputing higher income.
Health Insurance and Medical Support in North Dakota
North Dakota requires parents to maintain health insurance coverage for children through available employer-sponsored or government programs under NDAC § 75-02-04.1-01(6)(d). The parent receiving support must carry coverage if available at low or no cost; otherwise, the paying parent must provide coverage if available at reasonable cost. Health insurance premiums covering the child are factored into the support calculation, with the obligor's share added to the base guidelines obligation.
The incremental cost attributable to the child—not the entire family premium—determines the health insurance adjustment. If adding the child to an employer plan costs $200 monthly above employee-only coverage, that $200 represents the relevant premium for support calculations. A parent paying $800 monthly for family coverage where employee-only coverage costs $400 has $400 in child-attributable costs to allocate between parents based on respective incomes.
Uninsured Medical Expense Allocation
Uninsured medical expenses including copays, deductibles, orthodontia, prescriptions, and treatments not covered by insurance are typically split between parents according to court order terms. The North Dakota Child Support Division does not determine how these expenses are allocated—courts specify the division in support orders, commonly using 50/50 splits or income-proportional sharing. Parents should maintain detailed records and receipts for all uninsured medical expenses to facilitate reimbursement claims.
Modifying Child Support Orders in North Dakota
A child support modification requires demonstrating that changed circumstances make the current order inappropriate and that modification serves the child's best interests under N.D.C.C. § 14-09-08.1. Material changes include significant income increases or decreases (typically 15-20% or more), job loss, disability, additional children, changes in parenting time exceeding 30 overnights annually, or the child's special needs. Filing a motion to modify costs $160 as of July 1, 2025, and requires completing the Motion to Modify Support form with the district court.
The administrative review process through the North Dakota Child Support Division provides an alternative to court-based modification. Either parent may request a review every three years without demonstrating changed circumstances, or at any time if circumstances have materially changed. The Division reviews both parents' current incomes, applies the guidelines, and issues a proposed modification that becomes effective if neither party objects within 30 days.
How Long Modification Takes
Uncontested modifications typically take 2-4 months from filing to final order when both parties agree to revised terms. Contested modifications requiring hearings and evidence presentation take 4-8 months depending on court calendars. Administrative reviews through the Child Support Division typically complete within 30-60 days. No modification takes effect retroactively beyond the filing date—arrears at the original amount continue accumulating until the court or Division issues a modified order.
Child Support Enforcement in North Dakota
North Dakota employs multiple enforcement mechanisms when obligors fail to pay child support, including income withholding, tax refund interception, license suspension, and contempt proceedings. The Child Support Division can garnish wages directly from employers through income withholding orders, intercept federal and state tax refunds, seize bank accounts, and report delinquencies to credit bureaus. Unpaid balances do not discharge when children turn 18 or through bankruptcy filings, and North Dakota eliminated the statute of limitations on enforcement effective April 2, 1999.
License Suspension for Non-Payment
North Dakota law authorizes suspension of driver's licenses, hunting licenses, professional licenses, occupational licenses, and vehicle registrations when support is 2 months or $2,000 past-due, whichever is less, or upon breach of a payment plan. License suspension represents an extreme enforcement action reserved for cases where other collection methods prove ineffective. Reinstating a suspended license requires contacting the Child Support Division to establish a payment plan or pay arrears in full—simply making a single payment does not restore driving privileges.
Interest on Past-Due Support
North Dakota charges 11.00% annual interest (2025 rate) on past-due support when a North Dakota court ordered the support. Interest accrues on the past-due principal balance as simple interest, significantly increasing total amounts owed over time. A parent with $10,000 in arrears accumulates $1,100 in additional interest annually, making payment plans increasingly difficult to satisfy. Entering a compliant payment plan arrangement stops interest accrual on arrears during the compliance period.
When Child Support Ends in North Dakota
Child support in North Dakota continues until the child reaches age 18 or graduates from high school, whichever occurs later, with an outside limit of age 19. A child turning 18 in October of their senior year continues receiving support through graduation the following spring. Support terminates automatically upon the triggering event without requiring a court order, though obligors should confirm termination in writing with the Child Support Division to ensure proper account closure.
Support may terminate earlier upon the child's marriage, entry into military service, or emancipation through court order. Children achieving legal emancipation by demonstrating financial self-sufficiency and independent living no longer qualify for support regardless of age. Support obligations also terminate upon either parent's death, though life insurance provisions in divorce decrees may provide continued financial protection for children.
How to File for Child Support in North Dakota
Filing for child support in North Dakota begins with completing the Application for Child Support Services through the North Dakota Child Support Division or filing a petition with the district court in the county where the child resides. The Division provides services regardless of whether parents ever married, and applications may be submitted online, by mail, or in person at regional offices. Court-based filings require the Summons, Complaint, and Child Support Guidelines Worksheet forms with the $160 filing fee.
The Child Support Division locates absent parents, establishes paternity when necessary, calculates support using the guidelines, and obtains court orders—all without attorney fees for the applicant. Private attorneys typically charge $200-$400 hourly in North Dakota, making contested cases cost $1,500-$5,000 or more depending on complexity. Uncontested matters handled through the Division or simple agreed modifications typically cost only the filing fee.
Frequently Asked Questions About North Dakota Child Support
How much is child support in North Dakota for one child?
North Dakota child support for one child ranges from approximately $200 to $3,500 monthly depending on the paying parent's net income. A parent earning $3,000 monthly net income typically pays around $500 for one child (approximately 17% effective rate), while payments at the $25,000 monthly income cap reach $3,500. The average payment falls between $200 and $400 per month.
Does North Dakota use both parents' income to calculate child support?
North Dakota uses primarily the obligor's (paying parent's) income, not both parents' combined income, distinguishing it from the income-shares model used by 41 states. The custodial parent's income becomes relevant only for health insurance cost allocation and certain deviation analyses. This obligor-focused percentage-of-income approach simplifies calculations but may result in higher obligations for paying parents compared to income-shares states.
Can I modify child support if I lose my job in North Dakota?
Yes, job loss constitutes a material change in circumstances justifying modification under N.D.C.C. § 14-09-08.1. File a modification motion immediately ($160 filing fee) because support continues accruing at the original amount until a court issues a modified order. Courts may impute income if the job loss appears voluntary, so document termination circumstances and active job search efforts thoroughly.
How does 50/50 custody affect child support in North Dakota?
For equal residential responsibility (180+ overnights per parent annually), North Dakota calculates each parent's obligation separately using the guidelines schedule, then offsets the amounts. The higher-income parent pays the lower-income parent the difference between obligations. Two parents with identical incomes in a true 50/50 arrangement would owe zero support because obligations offset completely.
What happens if my ex doesn't pay child support in North Dakota?
North Dakota enforces unpaid support through wage garnishment, tax refund interception, bank account seizure, license suspension, credit reporting, and contempt proceedings with potential jail time. License suspension triggers when arrears reach 2 months or $2,000, whichever is less. Contact the Child Support Division to initiate enforcement actions, which remain available indefinitely since North Dakota eliminated the statute of limitations in 1999.
How long does child support last in North Dakota?
Child support continues until age 18 or high school graduation, whichever is later, with an outside limit of age 19 under N.D.C.C. § 14-09-09.7. A child turning 18 during senior year continues receiving support through graduation. Support may end earlier upon marriage, military enlistment, or court-ordered emancipation.
Can child support be waived in North Dakota?
No, an obligor cannot waive child support obligations under N.D.C.C. § 14-09-09.32. Child support belongs to the child, not the custodial parent, preventing parents from bargaining away support in exchange for other concessions. Courts will not approve agreements eliminating support obligations, though parents may agree to amounts above the guidelines minimum.
How is imputed income calculated in North Dakota?
Courts impute income using three methods: (a) 167 times federal minimum wage (approximately $1,213 monthly); (b) 60% of prevailing wages for persons with similar qualifications in the community; or (c) amounts consistent with prior earning history. The court selects the method most appropriate to the obligor's circumstances, typically using earning history for professionals and minimum wage calculations for those without marketable skills.
What income is included in North Dakota child support calculations?
Gross income includes wages, overtime, commissions, bonuses, severance, pensions, interest, dividends, social security benefits, workers' compensation, unemployment benefits, retirement benefits, gifts exceeding $1,000, spousal support received, and imputed earning capacity. Public assistance (TANF, SSI, food stamps) is excluded. Net income equals gross income minus taxes, FICA, mandatory retirement, health insurance, union dues, and prior support obligations.
How much does it cost to file for child support modification in North Dakota?
The filing fee for a child support modification motion is $160 as of July 1, 2025 (increased from $30 previously), with a $100 fee to file an answer. Attorney fees for contested modifications range from $1,500 to $5,000 depending on complexity. Administrative reviews through the Child Support Division cost nothing beyond the filing fee and provide a lower-cost alternative to court proceedings.
