How to change child support in Minnesota

How and when to ask for a new amount, with a review letter.

Checked against official sources: Oct 25, 2026.

Short answer

To modify an order means to change the amount by a new order. A change is presumed when the guidelines applied to current circumstances give an amount at least 20% and at least $75 a month higher or lower than the current order (if the order is under $75, at least 20%), or when a parent's gross income has dropped at least 20% through no fault or choice of their own.

When you can ask for a change in Minnesota

A change is presumed when the guidelines applied to current circumstances give an amount at least 20% and at least $75 a month higher or lower than the current order (if the order is under $75, at least 20%), or when a parent's gross income has dropped at least 20% through no fault or choice of their own. Other reasons include substantially changed income or needs, changed health coverage or child care costs, or emancipation of a child. Having a new child with someone else does not by itself justify a change.
