225 ILCS 447/40-30
A person who delivers a check or other payment to the Department that is returned to the Department unpaid by the financial institution upon which it was drawn shall pay to the Department, in addition to the amount already owed, a penalty of $50. The Department shall notify the person by first class mail that the person's check or payment was returned and that the person shall pay to the Department by certified check or money order the amount of the returned check plus a $50 penalty within 30 calendar days after the date of the notification. If, after the expiration of 30 calendar days of the notification, the person has failed to remit the necessary funds and penalty, the Department shall automatically terminate the license or deny the application without a hearing. If the returned check or other payment was for issuance of a license under this Act and that person practices as a licensee, that person may be subject to discipline for unlicensed practice as provided in this Act. If, after termination or denial, the person seeks a license, the person shall petition the Department for restoration and the person may be subject to additional discipline or fines. The Secretary may waive the penalties or fines due under this Section in individual cases where the Secretary finds that the penalties or fines would be unreasonable or unnecessarily burdensome.
