S.D. Codified Laws § 51A-17-23
A licensee shall electronically file an advance change notice through the nationwide mortgage licensing system and registry of a proposed change of control within fifteen days after learning of the proposed change of control and request approval of the acquisition. After review of a request for approval, the director may require the licensee to provide additional information concerning the proposed persons in control of the licensee. The additional information is limited to the same types required of the licensee or persons in control of the licensee as part of its original license or renewal application. The director shall approve a request for change of control if, after investigation, the director determines that the person or group of persons requesting approval has the competence, experience, character, and general fitness to operate the licensee or person in control of the licensee in a lawful and proper manner and that the interests of the public will not be jeopardized by the change of control.
