Ala. Code § 35-10-1
Where a power to sell lands is given to the grantee in any mortgage, or other conveyance intended to secure the payment of money, the power is part of the security, and may be executed by any person, or the personal representative of any person who, by assignment or otherwise, becomes entitled to the money thus secured; and a conveyance of the lands sold under such power of sale to the purchaser at the sale, executed by the mortgagee, any assignee or other person entitled to the money thus secured, his agent or attorney, or the auctioneer making the sale, vests the legal title thereto in such purchaser. Probate judges shall index foreclosure deeds by the names of the original grantor and grantee in the mortgage, and also by the names of the grantor and grantee in the foreclosure deeds.
