Both parents have a duty to support their children. The amount of child support paid by one party to the other is determined based upon the respective incomes of each of the parties and the amount of parenting time allocated to each of them. The legislature directed the Illinois Department of Healthcare and Family Services to adopt rules establishing child support guidelines which include worksheets to aid in the calculation of the child support obligations and a schedule of basic child support obligations that reflects the percentage of combined net income that parents living in the same household in this State ordinarily spend on their child.

Child support generally terminates with respect to each child when the child attains age 18 and graduates from high school, but not later than the child’s 19th birthday.
