What constitutes a substantial and material change in circumstances can range from losing or changing jobs to children leaving the home. Under theses circumstances either party can file with the court a Supplemental Petition to Modify.
However, increases in child support are generally retroactive only to the date of filing and reductions in child support are usually effective only from the date the court actually signs the order.
