Child support is meant to subsidize the care of children in the custodial household by funding a share of the costs for food, housing, clothing, daycare, medical care or health insurance, education and a host of other needs. The funds may also apply to athletic fees, summer camp, extracurricular activities, private schooling or any other child-related expenses. The exact expenses vary among families based on income and a child’s interests and any special needs. The state’s child support guidelines govern the calculation of child support unless the parents decide upon other amounts.
