If a parent is no longer with the other parent of their child in Illinois, there is a very good chance that one parent is ordered to pay child support to the other. The child support payment is generally paid by the non-custodial parent to the custodial parent. Child support is there to ensure that the child's basic needs, such as food, shelter and clothing are being met by both parents.
The amount of the child support is based on the child support guidelines. These state that the parent paying child support must pay the other parent a certain percentage of his or her adjusted gross income. The percentage of the income increases as the number of children increases. The percentage starts at 20 percent for one child and increases to 50 percent if there are six or more children.
