Ala. Code § 45-49A-84.05

When a nuisance lien is made against a lot or parcel of land, a subsequent redemption by a person authorized to redeem or sale of the lot or parcel by the state shall not operate to discharge, or in any manner affect, the nuisance lien of the city. A redemptioner or purchaser of any lot or parcel of land upon which a nuisance lien has been made shall take the lot or parcel subject to the nuisance lien, regardless of whether the redemption or purchase was before or after a sale to the state for the nonpayment of taxes.
