How to Modify Child Support in North Dakota
Reviewed by DocDraft Legal Team · North Dakota · Last updated September 21, 2026
In North Dakota, a child support modification is a district court or the state child support agency changing the dollar amount of an existing support order after finances or the parenting arrangement change. North Dakota adds a distinctive rule: if the order you want to change was entered at least one year before you file, the court must reset support to the current child support guideline amount, whether or not a material change of circumstances has occurred, unless that guideline result is rebutted (N.D.C.C. 14-09-08.4). If you file within one year of the order, you must also show a material change of circumstances. Support is calculated under guidelines the Department of Health and Human Services establishes, tied mainly to the obligor's income (N.D.C.C. 14-09-09.7), so a job loss, a raise, or a new schedule can move the number. You can ask in two ways. You can file a motion to amend with the district court that issued the order, or you can ask North Dakota Child Support to review your order if the agency handles your case. A change applies going forward only, and support that already came due cannot be modified retroactively (N.D.C.C. 14-08.1-05), so filing promptly protects you. Keep paying your current order until the court changes it. Attorney review of your filing is available through DocDraft.

How do I modify child support in North Dakota?
File a motion to amend with the North Dakota district court that issued your order, or ask North Dakota Child Support to review it if the agency handles your case. If the order is at least one year old, the court resets support to the current guideline amount unless that figure is rebutted (N.D.C.C. 14-09-08.4).
How much does income have to change to modify child support in North Dakota?
North Dakota sets no fixed percentage for a court motion once the order is at least one year old; the court recalculates support under the guideline (N.D.C.C. 14-09-08.4). The child support agency must seek a change when the order falls below 85 percent or above 115 percent of the guideline amount.
How far back can a child support change go in North Dakota?
A modification applies going forward, not to the past. Under N.D.C.C. 14-08.1-05, each support payment that is due and unpaid is not subject to retroactive modification, so support that already came due cannot be reduced or erased. Keep paying your current order until a judge changes it.
Which court handles child support modifications in North Dakota?
The North Dakota state district court that issued your existing order handles a motion to amend it. If North Dakota Child Support manages your case, you can also ask the agency to review the order, and it can pursue a change through the district court when one is warranted (N.D.C.C. 14-09-08.4).
North Dakota child support modification at a glance
In North Dakota, a child support modification is a district court or agency changing the amount of an existing support order after circumstances change. The distinctive rule here is timing: if the order was entered at least one year before you file, the district court must conform support to the current child support guideline, whether or not a material change occurred, unless the guideline amount is rebutted (N.D.C.C. 14-09-08.4). File within a year of the order and you must show a material change. Guidelines set by the Department of Health and Human Services drive the number (N.D.C.C. 14-09-09.7). You file a motion to amend in district court, or ask North Dakota Child Support to review your case. A change applies only going forward, and past-due support cannot be modified retroactively (N.D.C.C. 14-08.1-05).
Lowering a North Dakota order after a pay cut
Suppose your North Dakota order was entered two years ago, which means the district court must reset it to the current guideline amount without proof of a material change, because the order is more than one year old (N.D.C.C. 14-09-08.4). Your hours were recently cut, so you gather pay records, estimate the lower guideline figure (N.D.C.C. 14-09-09.7), and prepare the self-help motion to amend with a Financial Declaration. You file it in the district court that issued your order and serve the other parent. Because past-due support cannot be modified retroactively (N.D.C.C. 14-08.1-05), you file right away and keep paying the current amount until the judge rules. Attorney review of your filing is available through DocDraft.

Frequently Asked Questions
A real drop in income can support a lower amount, but you must file a motion to amend or ask the agency to review; support keeps accruing at the current rate until the court acts (N.D.C.C. 14-08.1-05). A judge may weigh whether you could reasonably earn more. Do not stop paying.
No. Either parent can file a motion to amend on their own, and the other parent is served and can respond. If both agree, they can present a stipulated amount, but the district court still measures it against the child support guideline before approving a new order (N.D.C.C. 14-09-09.7).
After you file the motion to amend, the district court sets a hearing, often several weeks to a few months out depending on the county. An agency review follows a separate process and can take longer. Filing promptly matters because a change applies only going forward (N.D.C.C. 14-08.1-05).
North Dakota Child Support reviews orders it enforces and must seek a change when support falls below 85 percent or above 115 percent of the guideline amount (N.D.C.C. 14-09-08.4). The agency does not change the order itself; it pursues an amendment through the district court when one is warranted.
You can file a motion to amend whenever the qualifying rules are met. If North Dakota Child Support enforces your case, the agency must review the order no less than every 36 months, matching the federal three year standard, and sooner on request when circumstances change (N.D.C.C. 14-09-08.4).
Past-due support, called arrears, is a judgment by operation of law and is not subject to retroactive modification (N.D.C.C. 14-08.1-05). A modification changes only future payments, so arrears already owed remain due and continue to accrue interest. Keep paying your current order to avoid building arrears.
It depends on timing. If your order was entered at least one year before you file, no material change is required; the court conforms support to the guideline unless that amount is rebutted (N.D.C.C. 14-09-08.4). If you file within one year of the order, you must show a material change.
North Dakota has no single numbered statewide modification form. The North Dakota Courts self-help center provides a motion packet with a Notice of Motion, Motion, Brief in Support, and a Financial Declaration reporting your income. You file these with the district court that issued your original order.
