755 ILCS 5/28-9
No person dealing with an independent representative is obliged to inquire as to the independent representative's powers under any will or court order or see to the application of any money or property paid or delivered to the independent representative. No will or court order limiting an independent representative's powers is effective as to a person with whom the independent representative deals, and such person may assume that the independent representative's act is in accordance with any applicable will or court order, unless such person has actual knowledge of the limitation. If property or a security interest therein is acquired in good faith by a purchaser or lender for value from an independent representative, the purchaser or lender takes title free of the rights of all persons having an interest in the estate and incurs no liability to the estate, whether or not the action of the independent representative was proper.
