S.D. Codified Laws § 27B-7-28
If a petition filed pursuant to § 27B-7-27 appears on its face to be sufficient, the chair of the county review board shall order that a psychiatric or psychological evaluation be performed and a report of the findings and recommendations be completed. The board chair shall appoint a licensed psychologist or psychiatrist within three days after receipt of the petition. The licensed psychologist or psychiatrist shall make the examination and prepare a report within five working days from receipt of the written notice from the board ordering the examination and report, containing the information required in § 27B-7-31. If it appears, based upon the foregoing evaluation, the criteria for commitment is met, a copy of the report shall be provided to Department of Human Services. The person has the right to obtain an additional examination paid for by the county that may be placed in evidence before the board, the reasonable expense of which shall be reimbursed to the county unless the person is indigent. A lien for the amount of these costs may be filed upon the person's real and personal property to ensure payment.
