The Illinois Petition To Terminate-Modify Child Support-Visitation is a legal document used to modify or terminate a current child support order or visitation agreement. It is used when one or both parents need to alter the existing arrangement due to changes in circumstances, such as relocation, financial hardship, or changes in the child's needs. The petition can also be used to modify or terminate an existing agreement when one or both parents have remarried or changed their place of residence. There are two types of Illinois Petition To Terminate-Modify Child Support-Visitation: Motion to Modify Child Support and Motion to Modify Visitation. The Motion to Modify Child Support is used when one or both parents want to change the amount of financial support the other parent pays for the child’s living expenses. The Motion to Modify Visitation is used when one or both parents want to change the amount of time the child spends with the other parent. Both motions must be filed with the court and the other parent must be notified of the filing.
