Either parent may file a petition or motion to modify a child support order—upward or downward—but usually only when there is a substantial change in the child’s needs, or in one or both of the parents’ incomes or net resources, that justifies the court revisiting and possibly modifying the earlier child support order.
The petition or motion to modify child support generally must be filed in the same court that issued the original or most recent child support order. But if the child lives in a different county or state, the courts of the county or state where the child lives may be the proper place to file a petition or motion to modify a child support order.
In Missouri, either parent has the right to request a modification of a child support order if there has been a substantial and continuing change in circumstances. This change could be related to the child's needs or a significant change in the income or financial resources of either parent. To seek a modification, a parent must file a motion or petition with the court that originally issued the child support order. However, if the child has since moved to a different county or state, the parent may need to file the motion in the court that has jurisdiction over the child's current residence. It's important to note that the court will consider the best interests of the child when deciding whether to grant a modification. Parents are encouraged to consult with an attorney to navigate the process effectively.
