Child support provides the custodial parent with funds to pay for the child’s needs including clothing, food and shelter. In Ohio, the court determines child support based upon the earning ability of both spouses. You can file a motion with the court that issued your original chidl support order, asking the court for a modification of support. Or, you can contact the Child Support Enforcement Agency, CSEA, and ask for an administrative review of your child support order. However, you can only ask the CSEA for a review of the child support order once every 36 months .
