The Illinois Petition To Modify Suspend Or Terminate Order For Withholding is a form used when a party to an existing child support order wishes to modify, suspend, or terminate the withholding order from the non-custodial parent's wages. The form must be filed in the circuit court in the county where the child support order was entered. The form includes information such as the petitioner's name, address, and contact information, the name and address of the non-custodial parent, a description of the existing child support order, and the reasons why the petitioner is requesting a modification, suspension, or termination of the withholding order. There are two types of Illinois Petition to Modify Suspend or Terminate Order for Withholding: one for modification and one for suspension or termination.
