In Illinois is the non-custodial parent responsible for college if it wasn't in the divorce decree 18 years ago?

In Illinois, a non-custodial parent is generally not legally required to pay for a child's college expenses unless it was specified in the divorce decree or if both parents agree to such an arrangement. Illinois law does allow for the possibility of college expenses to be addressed in a post-divorce agreement or if the parties enter into a new agreement regarding college funding. However, absent such stipulations in the divorce decree, the non-custodial parent is not automatically responsible for college costs. It is advisable to consult with a family law attorney for specific guidance based on individual circumstances.
