Ala. Code § 11-70-6
If the municipality is unable to identify the names and addresses of interested parties, or is unable to provide notice under Section 11-70-5, the municipality shall apply to the circuit court for an order to allow notice by publication. If so ordered, the municipality shall publish a notice once each week for three consecutive weeks in a newspaper of general circulation in the county in which the property is located. If no newspaper is published in that county, publication shall be made in a newspaper of general circulation in an adjoining county. This publication shall substitute for notice under subdivision (1) of subsection (a) of Section 11-70-5. The published notice shall include the information listed in subsection (b) of Section 11-70-5. If the municipality discovers the name and address of an interested party following publication, it shall notify that party of the expedited quiet title and foreclosure action in accordance with subdivision (1) of subsection (a) of Section 11-70-5 as soon as practicable, in which case notice shall be brought to the attention of the court which shall postpone the hearing for a period of time sufficient to give such notice to the newly discovered party.
