815 ILCS 390/13
A licensee may surrender any license by delivering to the Comptroller written notice that he thereby surrenders such license but such surrender shall not affect such licensee's civil or criminal liability for acts committed prior to such surrender, or affect his bond. The Comptroller shall not permit a license to be surrendered by licensee unless and until the trust funds of such licensee have been transferred to a successor licensee who shall be licensed by the Comptroller in conformity with the provisions of this Act. Any purported transfer of trust funds without compliance with this Section is void and the Comptroller shall have the right to petition for the appointment of a receiver to administer the business of the licensee.
