Illinois Order On Prove Up is a legal document issued by a court in the state of Illinois that requires both parties in a divorce to appear before the court to prove that all assets and liabilities have been accounted for and divided according to the divorce agreement. The Order is generally issued after all other issues such as custody, alimony, and child support have been settled. It is a binding document that must be followed by both parties. There are two types of Illinois Order On Prove Up: Final Order On Prove Up and Temporary Order On Prove Up. A Final Order is issued after all other issues have been settled in the divorce agreement and is used to finalize the divorce. A Temporary Order is typically used when a divorce is pending and one or both parties need temporary relief from certain elements of the divorce such as alimony and child support.
