The owner, or any persons for him with his consent, or any person interested in the land sold for taxes, may redeem the same, or any part of it, where it is separable by legal subdivisions of not less than forty (40) acres, or any undivided interest in it, at any time within two (2) years after the day of sale, by paying to the chancery clerk, regardless of the amount of the purchaser's bid at the tax sale, the amount of all taxes for which the land was sold, with all costs incident to the sale, and five percent (5%) damages on the amount of taxes for which the land was sold, and interest on all such taxes and costs at the rate of one and one-half percent (1-1/2%) per month, or any fractional part thereof, from the date of such sale, and all costs that have accrued on the land since the sale, with interest thereon from the date such costs shall have accrued, at the rate of one and one-half percent (1-1/2%) per month, or any fractional part thereof; saving only to infants who have or may hereafter inherit or acquire land by will and persons of unsound mind whose land may be sold for taxes, the right to redeem the same within two (2) years after attaining full age or being restored to sanity, from the state or any purchaser thereof, on the terms herein prescribed, and on their paying the value of any permanent improvements on the land made after the expiration of two (2) years from the date of the sale of the lands for taxes. Upon such payment to the chancery clerk as hereinabove provided, he shall execute to the person redeeming the land a release of all claim or title of the state or purchaser to such land, which said release shall be attested by the seal of the chancery clerk and shall be entitled to be recorded without acknowledgment, as deeds are recorded. Said release when so executed and attested shall operate as a quitclaim on the part of the state or purchaser of any right or title under said tax sale.
