S.D. Codified Laws § 54-6A-4
The lessor shall disclose to the consumer the information required by this chapter. In a transaction involving more than one lessor, only one lessor need make the disclosures, but all lessors shall be bound by such disclosures. The disclosures shall be made at or before consummation of the lease-purchase agreement. The disclosures shall be made clearly and conspicuously in writing and a copy of the lease-purchase agreement provided to the consumer. The disclosures required under § 54-6A-5 shall be made on the face of the contract above the line for the consumer's signature.
If a disclosure becomes inaccurate as the result of any act, occurrence, or agreement by the consumer after delivery of the required disclosures, the resulting inaccuracy is not a violation of this chapter.
