Ala. Code § 4-3-4
The certificate of incorporation of the authority shall be signed and acknowledged by the incorporators before an officer authorized by the laws of the state to take acknowledgments to deeds and shall have attached thereto a certified copy of each of the resolutions provided for in Section 4-3-2 and a certificate by the Secretary of State that the name proposed for the authority is not identical to that of any other corporation organized under the laws of the state or so nearly similar thereto as to lead to confusion and uncertainty. The certificate of incorporation of the authority, together with the documents required by the preceding sentence to be attached thereto, shall be filed for record in the office of the judge of probate of the county specified in the certificate of incorporation as the county in which the principal office of the authority shall be located. The judge of probate shall forthwith receive and record the same. When such a certificate of incorporation and attached documents have been so filed, the authority referred to therein shall come into existence and shall constitute a public corporation under the name set forth in such certificate of incorporation, whereupon the authority shall be vested with the rights and powers herein granted.
