An Illinois Order Appointing Administrator is a legal document issued by the probate court in the state of Illinois. It grants authority to a person or persons to handle the affairs of an estate of someone who has passed away without a will. Depending on the particular circumstances, there are two types of Illinois Order Appointing Administrators: Letters of Office or Letters of Administration. Letters of Office are issued when someone has died with a will and appointed an executor in their will. Letters of Administration are issued when someone has died intestate (without a will). The administrator is responsible for collecting and managing the deceased’s assets, filing any necessary taxes, and distributing the assets according to the law. The administrator is also responsible for filing periodic reports to the court concerning the estate’s assets and liabilities.
