(a) Upon payment of the sum necessary to redeem, the auditor shall execute a certificate of redemption in triplicate, which certificate shall specify the real estate redeemed, or the interest therein, as the case may be, together with any changes in respect thereto which were made in the land book and in the record of delinquent lands, shall specify the year or years for which payment was made, and shall state that it is a receipt for the money paid and a release of the state's lien against the real estate redeemed. The original certificate shall be retained in the files in the auditor's office, one copy shall be delivered to the person redeeming and the second copy shall be mailed by the auditor to the clerk of the county commission of the county in which the real estate is situated, who, after making any necessary changes in his record of delinquent lands, shall note the fact of redemption on such record, and shall record the certificate in a separate volume provided for the purpose.
The fee for issuing the certificate of redemption shall be ten dollars or seven and one-half percent of the total taxes, interest and charges due, whichever is greater.
(b) All certificates of redemption issued by the auditor in each year shall be numbered consecutively and shall be filed by the clerk of the county commission in numerical order. Reference to the year and number of the certificate shall be included in the notation of redemption required of the clerk of the county commission. No fee shall be charged by the clerk for any recordation, filing or notation required by this section.
