For most parents who pay child support, their obligations end when the child graduates from high school or turns 19 years old. By that time, the child should be capable of obtaining employment and supporting him- or herself. Many young adults, however, choose to continue their education at a college, university, or trade school before entering the workforce. If you have been paying child support for a child who recently graduated from high school, the law in Illinois says you may be on the hook to help your child pay for college depending on the circumstances.
If you have a child in Illinois and separate from the child’s other parent, one of you will be ordered to pay child support to the parent who has primary custody over the child. Illinois child support is calculated as a percentage of the payor parent’s take-home pay. The precise percentage depends on the total number of children the parents have in common (not necessarily the total number of children of the payor parent).
