A child support judgment can be appealed, but the procedure differs by jurisdiction.
The procedures for seeking an official review of a child support judgment differ by state, as do the factors for qualifying for a review. You may be allowed to seek an evaluation in the following circumstances:
If your state has a child support compliance agency, you may be able to seek a review over the phone, by writing a Child Support Review Letter, or by completing another state-specific document.
To have the ruling changed, a motion must be filed with the judge in some jurisdictions. It is recommended to confer with a child support expert in this circumstance.
Check the U.S. Department of Health and Human tools for child support tools by state for more information on processes for changing child support payments. Find a family counsel in your region for more assistance.
