S.D. Codified Laws § 32-3-27
Except as provided in § 32-3-26 for licensed dealers, if the application for certificate of title is presented more than forty-five days after date of assignment of the certificate of title or the manufacturer's certificate of origin of the motor vehicle, trailer, or semitrailer to the purchaser, the officer receiving the application shall collect, in addition to the fee established in § 32-3-18, a late fee of one dollar for each week or fraction thereof beyond the forty-five day limitation for twenty-five weeks and a late fee of fifty dollars for twenty-six weeks or more. Any person applying for a title more than ninety days after the date of assignment is guilty of a Class 2 misdemeanor. If the purchaser of a vehicle fails to comply with the provisions of § 32-3-26 to transfer the title within forty-five days, and the seller files a written complaint attesting to the facts, the purchaser is guilty of a Class 2 misdemeanor.
