Ala. Code § 43-2-842
A person who, in good faith, either assists a personal representative or deals with the personal representative for value is protected as if the personal representative properly exercised the power. The fact that a person knowingly deals with a personal representative does not alone require the person to inquire into the existence of a power or the propriety of its exercise. Except for restrictions on powers of personal representatives which are endorsed on the letters, no provision in any will or order of court purporting to limit the power of a personal representative is effective except as to persons with actual knowledge thereof. A person is not bound to see to the proper application of estate assets paid or delivered to a personal representative. The protection here expressed extends to instances in which some procedural irregularity or jurisdictional defect occurred in proceedings leading to the issuance of letters, including a case in which the alleged decedent is found to be alive. The protection here expressed is not by substitution for that provided by comparable provisions of the laws relating to commercial transactions and laws simplifying transfers of securities by fiduciaries.
