Expert witness discovery is governed by South Dakota’s Rules of Civil Procedure, § 15-6-26(b). S.D. Codified Laws § 15-6-26(b) (2017). This rule allows discovery of the fees and expenses associated with an expert’s testimony upon motion by a party. Id. Case law does not specifically discuss other financial information regarding experts, but it does note that the trial court is given discretion to determine whether to grant discovery requests. State v. Buchholz, 598 N.W.2d 899 (S.D.1999). Additionally, the discovery rules should be interpreted to provide for liberal discovery. Bean v. Best, 80 N.W.2d 565 (S.D. 1957).
