305 ILCS 5/10-17.13
The Illinois Department may provide by rule for certification to municipalities of past due support owed by responsible relatives under a support order entered by a court or administrative body of this or any other State on behalf of resident or non-resident persons. The purpose of certification shall be to effect collection of past due support by immobilization and impoundment of vehicles registered to responsible relatives pursuant to ordinances established by such municipalities under Section 11-1430 of the Illinois Vehicle Code.
The rule shall provide for notice to and an opportunity to be heard by each responsible relative affected, and any final administrative decision rendered by the Department shall be reviewed only under and in accordance with the Administrative Review Law. A responsible relative may avoid certification to a municipality for vehicle immobilization or arrange for discontinuance of vehicle immobilization and impoundment already engaged by payment of past due support or by entering into a plan for payment of past and current child support obligations in a manner satisfactory to the Illinois Department.
