What Counts as a Material Change in Circumstances for Child Support in North Dakota
In North Dakota, a child support order at least a year old is conformed to the guidelines without proving a material change, unless the presumption is rebutted. Within a year you must show one.
What is a material change for child support in North Dakota?
The statute does not give a general definition, but it names three that always count: a determination that the child is eligible for certain public benefits, the availability of health insurance at reasonable cost to the child, and the need to provide for the child’s health care needs through insurance or other means (NDCC 14-09-08.4(5)). Other changes, such as income or parenting time, must be shown by evidence when you need to prove one.
When do I not need to prove a material change in North Dakota?
When the support obligation sought to be amended was entered at least one year before the motion or petition. Then the court shall order the amendment to conform the amount to the guidelines, whether or not a material change has taken place, unless the presumption that the guidelines produce the correct amount is rebutted (14-09-08.4(4)). If the motion is filed within a year of the entry of the order, you must also show a material change. The North Dakota child support modification calculator asks the one-year question.
What is the North Dakota 85% to 115% band?
When the agency reviews an order, it may seek an amendment if the order is inconsistent with the guidelines amount, and it shall seek one if the order is less than 85% or more than 115% of the amount the guidelines would require (14-09-08.4(3)).
| Guideline amount | Agency must seek below | or above |
|---|---|---|
| $500 | $425 | $575 |
| $800 | $680 | $920 |
| $1,000 | $850 | $1,150 |
| $1,500 | $1,275 | $1,725 |
An $800 order against a $1,000 guideline amount is 25% lower than the order itself and is below $850, so the agency must seek an amendment; an $800 order against $900 is inside the band.
Is the North Dakota presumption rebuttable?
Yes. The court conforms the order to the guidelines unless the presumption is rebutted (14-09-08.4(4)). The administrative rule on guidelines lists the grounds on which the amount can be adjusted, such as imputed income, incarceration and other circumstances (N.D. Admin. Code ch. 75-02-04.1).
Can I challenge an agency decision not to seek a change?
Yes. If the agency decides not to seek an amendment, its notice must tell the obligor and the obligee that either can challenge that decision by seeking an amendment from the court at any time before the support order terminates (14-09-08.7).
From what date can the order change?
Support already due is a judgment by operation of law that is not subject to retroactive modification (14-08.1-05). Every month before you file is lost:
| Monthly difference | Lost after 6 months | Lost after 12 months |
|---|---|---|
| $100 a month | $600 | $1,200 |
| $200 a month | $1,200 | $2,400 |
| $400 a month | $2,400 | $4,800 |
Federal law also bars retroactive modification of support already due (42 U.S.C. 666(a)(9)).
