20 ILCS 505/21.1
In any proceeding in which the Department of Children and Family Services is a party, books, papers, records, warrants, computer printouts and memoranda showing the status of financial obligations owed to the Department of Children and Family Services by any person may be proved by a photostatic or reproduced copy thereof under the certificate of the Director of the Department of Children and Family Services. Such certified copies shall, without further proof, be admitted into evidence in the hearing before the Department, in an investigation or in any other proceeding. Nothing in this paragraph is intended to alter the rules governing admissibility of evidence in proceedings in which financial obligations owed to the Department are not in issue.
