Child support may be modified when there has been a substantial change of circumstances. Typically the court consider a 10-20% difference in child support to be a substantial change of circumstances. The guidelines where revised in the last 5 years so I recommend you attempt to discern what impact the revision may have on your case. Please let me know if you have any questions. Many thanks
