Ala. Code § 11-50-56: Giving of Notice Under Provisions of Division.

Whenever in the exercise of any power granted under this division notice is required to be given, the mayor and aldermen or other governing body may designate a person or persons to give such notice, who shall be a bonded officer of the municipality, and to make returns upon the same, and such return shall be prima facie evidence of such notice.

Personal notice to nonresidents shall not be necessary, and the mayor and aldermen or other governing body may provide and fix the character of the publication of notice to nonresidents, which shall be given by publication once a week for three weeks or by posting for the same time in three public places in said city or town where no newspaper is published therein.

Whenever any notice to a resident property owner is returned not found, the mayor and aldermen or other governing body may prescribe and issue alias notices to be served as in the case of the original notice. Two returns of “not found” as to a resident property owner shall authorize the mayor and aldermen or other governing body to proceed to give notice to such resident property owner by publication as herein required to be given to nonresidents.
