Except as otherwise provided in Section 21-375, any property forfeited to the county may be redeemed or sold in the following manner:
When property has been forfeited for delinquent general taxes, the person desiring to redeem shall apply to the county clerk who shall order the county collector to receive from the person the amount of the forfeited general taxes, statutory costs, interest prior to forfeiture, printer's fees due thereon and, in addition, forfeiture interest at a rate of 12% per year or fraction thereof. Upon presentation of the county clerk's order to the county collector, the collector shall receive the amount due on account of forfeited general taxes and give the person duplicate receipts, setting forth a description of the property and amount received. One of the receipts shall be countersigned by the county clerk and, when so countersigned, shall be evidence of the redemption of the property. The receipt shall not be valid until it is countersigned by the county clerk. The other receipt shall be filed by the county clerk in his or her office, and the clerk shall make a proper entry of the redemption of the property on the appropriate books in his or her office and charge the amount of the redemption to the county collector.
In counties with 3,000,000 or more inhabitants, when property has been forfeited because of the nonpayment of delinquent special assessments, the county clerk shall collect from the person desiring to redeem the amount due on the delinquent special assessment, together with the interest, costs and penalties fixed by law, and shall issue a receipt therefor setting forth a description of the property and the amount received. The receipt shall be evidence of the redemption of the property therein described. In addition, the city comptroller or other officer designated and authorized by the city council, board of trustees or other governing body of any municipal corporation which levied any special assessment shall have power to collect the amounts due on properties which have been forfeited, and the interest and penalties due thereon, based upon an estimate of the cost of redemption computed by the county clerk and at a rate to be fixed by the city council, board of trustees or other governing body as to the interest and penalties due thereon and shall issue a receipt therefor. The person receiving the receipt shall file with the county clerk the receipt of the municipal officer that such special assessments and interest and penalties have been paid. Upon the presentation of the receipt the county clerk shall issue to the person a certificate of cancellation setting forth a description of the property, the special assessment warrant and installment, and the amount received by the municipal officer. The certificate of cancellation shall be evidence of the redemption of the property therein described. The city council, board of trustees, or other governing body may authorize the municipal officer to waive penalties for the first year in excess of 7%. The form of the receipt of redemption for filing with the county clerk shall be as prescribed by law.
In counties with less than 3,000,000 inhabitants, when property has been forfeited in whole or in part for the non-payment of delinquent special assessments, the person desiring to redeem shall apply to the municipal collector who shall receive the amount due on the delinquent special assessment, together with the interest, costs and penalties fixed by law, and issue a certificate therefor. The recipient shall file the certificate of the municipal collector that the special assessments and the costs, interest and penalties thereon have been paid with the county clerk. The municipal collector's certificate of payment shall be filed by the county clerk in his or her office and the clerk shall make a proper entry of the redemption on the books in his or her office.
This Section 21-370 does not apply to any forfeiture that occurs on or after January 1, 2024.
