SDCL § 21-22-24: Referee or accountant appointed to assist in examination of reports--Report confidential.

If the report or account or other proceeding is of such length as to require assistance for the court, the court may in its discretion appoint a disinterested referee or employ an accountant or investigator at the expense of the trust to examine the same and report to the court thereon independently. Such report may be held by the court as confidential and for its own information, if the court so elects.
