Ala. Code § 40-10-133
When application is made to the Land Commissioner by any person to purchase lands in which such person had no interest, the Land Commissioner shall mail a notice in writing to the owner, or some person having an interest in such land, if his place of residence is known, or, if not known, then to the judge of probate of the county in which such lands are situated, informing him that such application has been made and fixing a reasonable time within which such owner or such other person having an interest in the lands may redeem the same. The judge of probate shall cause the notice to be posted at the courthouse, and he shall mail a copy of said notice to the owner, if known to him; and if such lands are not redeemed within the time so fixed, the same shall be sold to the applicant or any other person desiring to purchase the same without other or further notice to such owner or persons having an interest in the lands. If such lands are redeemed within the time so fixed, the judge of probate must, without delay, report the same to the Land Commissioner and pay over the redemption money as required by law.
