The Illinois Petition to Modify, Suspend or Terminate Order for Withholding is a legal document used to modify, suspend, or terminate the order of income withholding in the state of Illinois. This document is typically used when a non-custodial parent is ordered to have a certain amount of their income withheld to pay for child support. The petition must be filed in the circuit court in the county where the Order for Withholding was issued. There are two types of Illinois Petition to Modify, Suspend or Terminate Order for Withholding: the Petition to Modify Order for Withholding and the Petition to Terminate Order for Withholding. The Petition to Modify Order for Withholding is used to modify an existing order of income withholding for a non-custodial parent, while the Petition to Terminate Order for Withholding is used to terminate an existing order of income withholding. Both forms require the petitioner to provide information regarding their income and the income of the non-custodial parent.
