S.D. Codified Laws § 43-30 app. A-01
The purpose of the examination of title and of objections, if any, shall be to secure for the examiner's client a title which is in fact marketable and which is shown by the record to be marketable, subject to no other encumbrances than those expressly provided for by the client's contract. Objections and requirements should be made only when the irregularities or defects reasonably can be expected to expose the purchaser or lender to the hazard of adverse claims or litigation.
When an examiner finds a situation which he believes creates a question as to marketable title and has knowledge that another attorney handled the questionable proceeding or has passed the title as marketable, the examining attorney before writing an opinion, should communicate, if feasible, with the other attorney and afford an opportunity for discussion.
