S.D. Codified Laws § 51A-6A-47
A person acquiring control through direct or indirect ownership by an owner or an affiliated group of owners shall give the director at least sixty days prior written notice of any proposed trust company acquisition. If the director does not issue an order disapproving the proposed acquisition within that time or extend the period during which a disapproval may be issued, the proposed acquisition is approved. The period for disapproval shall be thirty days after notice is received by the director and may be further extended only if the director determines that any acquiring person has not furnished all the information required under § 51A-6A-48 or if in the director's judgment, any material information submitted is substantially inaccurate. An acquisition may be made prior to expiration of the disapproval period if the director issues written notice of the director's intent not to disapprove the action.
If the director disapproves an acquisition, the director shall serve the acquiring person with an order of disapproval. The order shall provide a statement of the basis for the disapproval. Within thirty days after service of an order of disapproval, the acquiring person may request a hearing on the proposed acquisition with the commission. Upon receipt of a timely request, the commission shall conduct a hearing in accordance with the provisions of chapter 1-26. Any disapproval by the commission of a proposed acquisition is subject to review in accordance with chapter 1-26.
Actual expenses incurred by the director or commission in carrying out any investigation that may be necessary or required by statute shall be paid by the person submitting the proposed acquisition.
