740 ILCS 80/14
In all cases where a judgment has been obtained against the executor or administrator of a deceased person, on a contract or undertaking on which a joint action might have been maintained against the executor or administrator, and the heir or devisee of the deceased person, if it shall appear by a judgment of record or the return of a proper officer that there is not property of the deceased person in the hands of the executor or administrator to satisfy such judgment, it shall be lawful to bring a separate suit or action against the heir or devisee on such contract or undertaking; and the judgment against the executor or administrator, if not satisfied, shall be no bar to the suit or action against the heir or devisee.
