Information On Modification

To ensure child support awards are in line with changing circumstances, CSE conducts triennial reviews of child support orders. On non-TANF cases, CSE conducts reviews if requested. On a TANF (Temporary Assistance for Needy Families) or MO HealthNet case, CSE either performs a review on its own or at either parent’s request.

In conducting the review, CSE decides if a modification is appropriate by determining: (1) if a child support award figured using Missouri child support guidelines differs by 20 percent or more from the existing child support obligation; (2) if a health insurance provision needs to be added to the order. If three years have passed since the order was entered, last reviewed, or modified and either or both of the above criteria are met, CSE will initiate a modification of the order.
