Door 1 · Lower my child support
Will my child support go down? Run your state's test.
Enter what you pay now and what changed. The checker recalculates the guideline figure from your state's published schedule or percentage, then runs the exact modification test your state prints in its law — and tells you, with the citation, whether the numbers meet it.

The kit
Child Support Modification Kit — $39, one-time
Everything the free tool points to, written out in full: walkthroughs, worksheets, letters, and trackers for your state. One payment. Yours to keep.
Two tracks, always: Track A is arithmetic — the published test on your numbers. Track B is evidence — the change-in-circumstances showing, described as a checklist and never scored. Rules checked October 2026.
