Ala. Code § 6-6-392
When the garnishment is in aid of a pending action, the plaintiff, his agent or attorney must also give bond in double the amount claimed in the action, with sufficient surety, to be approved by the officer issuing the writ, with condition that the plaintiff will prosecute the garnishment to effect and pay the defendant all such damages as he may sustain from the wrongful or vexatious suing out of such garnishment; and such bond, as to actions thereon, is subject to the provisions of this code relating to actions on attachment bonds; provided, however, that the Superintendent of Banks of the State of Alabama shall not be required to give bond when garnishment is issued in aid of a pending action, which action is based on a promissory note owned by a bank in the process of liquidation. Such Superintendent of Banks or the liquidating agent of such bank in liquidation shall, however, be liable on his official bonds for damages sustained from the wrongful or vexatious suing out of a writ of garnishment. The Superintendent of Banks shall, however, be required to obtain an order from the circuit court of the county in which such bank in liquidation is located, exempting the Superintendent of Banks from giving such bonds. The order need not specify the particular case or cases, but may be general and exempt the Superintendent of Banks from giving bond in all cases to be brought by him on promissory notes owned by the bank in liquidation wherein garnishments are to issue in aid of the pending actions.
