S.D. Codified Laws § 51A-6A-39
All information the director generates in making an investigation or examination of a state trust company is confidential. All confidential information shall remain the property of the division and shall be furnished to the trust company for its confidential use. Under no circumstances may a trust company disclose a report or any supporting documentation to anyone, other than directors and officers of the trust company or anyone acting in a fiduciary capacity for the trust company, without written permission from the director.
The director shall give ten days' prior written notice of intent to disclose confidential information to the affected trust company. Any trust company which receives a notice may object to the disclosure of the confidential information and shall be afforded the right to a hearing in accordance with the provisions of chapter 1-26. If a trust company requests a hearing, the director may not reveal confidential information prior to the conclusion of the hearing and a ruling. Disclosure of confidential information shall be made only to formal regulatory bodies which clearly have a need for the confidential information. Prior to dissemination of any confidential information, the director shall require a written agreement not to reveal the confidential information by the party receiving the confidential information. In no event may the director disclose confidential information to the general public, any competitor, or any potential competitor of a trust company.
The submission of any information to the division in the course of any investigation or examination may not be construed as waiving, destroying, or otherwise affecting any privilege any person may claim with respect to the information under South Dakota law or federal law.
