Ala. Code § 11-53B-8
If the property owner fails to pay the assessment lien within 30 days, or having elected to make installment payments, fails to make any installment payment when due, the whole assessment lien shall immediately become due and payable, and the officer designated by the municipality to collect the assessment lien shall proceed to sell the property against which the assessment lien is made to the highest bidder for cash, but in no event less than the amount of the lien plus interest through the date of default. Prior to the sale, notice shall be given by publication once a week for three consecutive weeks in a newspaper published in the municipality or of general circulation therein, setting forth the date and time of the sale and the purpose for which the same is made, together with a description of the property to be sold. If the officer shall fail to advertise and sell any property on which the payments are past due, any taxpayer of the issuing municipality shall have the right to apply for a writ of mandamus requiring the official to take such action to any court of competent jurisdiction, and the court shall, on proof, issue and enforce the writ.
