Quick answer: In North Dakota, if a child support order is at least one year old, the court shall amend it to match the guidelines, with no material change needed, unless the presumption that the guideline amount is correct is rebutted. Within a year of the order you must show a material change. Support already due is a judgment that cannot be modified retroactively.
This North Dakota child support modification calculator applies NDCC 14-09-08.4. Enter your current order and the amount the guidelines give today (you can get it from the North Dakota child support calculator), say whether the order is at least a year old, and it shows whether you must prove a material change, whether the agency must seek an amendment, the monthly gap and what it adds up to.

What does this modification calculator check?
The calculator shows whether the one-year condition removes the need to prove a material change, whether the order is outside 85% to 115% of the guideline amount (which obliges the agency to seek an amendment), the monthly gap and the accrued difference after filing. It cannot decide whether the guideline amount is rebutted.
