An Illinois Order Terminating Support is a legal document issued by a court in the state of Illinois. It is used to end or modify the obligation to pay ongoing child support or spousal maintenance (alimony). There are two types of an Illinois Order Terminating Support: an Order of Termination of Support and an Order of Modification of Support. An Order of Termination of Support terminates all existing child support or spousal maintenance payments, while an Order of Modification of Support modifies the existing support payments, either decreasing or increasing the amount due. An Illinois Order Terminating Support must be signed by a judge and is legally binding.
