The certificate of incorporation may at any time and from time to time be amended so as to make any changes therein and add any provisions thereto which might have been included in the certificate of incorporation in the first instance.

Such an amendment shall be effected in the following manner: The board of the authority shall file with the governing body of each authorizing subdivision a resolution seeking permission to amend the certificate of incorporation, specifying in such resolution the amendment proposed to be made. The governing body of each authorizing subdivision shall consider such resolution and, if each of them shall by appropriate resolution duly find and determine that it is wise, expedient, necessary, or advisable that the proposed amendment be made and shall authorize the same to be made and shall approve the form of the proposed amendment, then the authority shall cause to be executed an instrument embodying the proposed amendment and shall file the same with the judge of probate of the county in which the certificate of incorporation was originally filed. The proposed amendment shall be subscribed and acknowledged by its president or vice president before an officer authorized by the laws of Alabama to take acknowledgments to deeds. Such judge of probate shall thereupon examine the proposed amendment and, if he finds that the requirements of this section have been complied with and the proposed amendment is within the scope of what might be included in an original certificate of incorporation, he shall approve the amendment and record it in an appropriate book in his office. When such amendment has been so made, approved, and filed, it shall thereupon become effective and the certificate of incorporation shall thereupon be amended to the extent provided in the amendment. No certificate of incorporation shall be amended except in the manner provided in this section. The recording of the amendment shall be conclusive evidence that the requisite findings and approvals have been made.
