Alabama Code Title 23. Highways, Roads, Bridges, and Ferries § 23-7-21

(a) Any pledge made by the bank to secure its obligations with respect to bonds or other financial assistance is valid and binding from the time the pledge is made. The revenue, money, or property pledged and received by the bank is immediately subject to the lien of the pledge without any physical delivery or further act. The lien of any pledge is valid and binding as against all parties having claims of any kind in tort, contract, or otherwise against the bank, irrespective of whether the parties have notice of the pledge.

(b) No recording or filing of the resolution authorizing the issuance of bonds or other financial assistance, the trust indenture or other financing agreement securing the bonds or other financial assistance, or any other instrument including filings under the Uniform Commercial Code is necessary to create or perfect any pledge or security interest granted by the bank to secure any bonds or other financial assistance.
