(b) Should any person entitled to serve as trustee under an inter vivos or testamentary instrument die, decline to serve or resign and if:

(c) Upon motion of the personal representative, an interested party, or upon the court's own motion, the probate court or chancery court may appoint the public receiver to determine the need for a temporary or permanent receiver. The public receiver must submit a report of its recommendations to the court, which report must be served via United States mail to the personal representative and all known interested parties. The report is subject to the same review as a report of a special master. Upon a hearing, the court may appoint a receiver with such powers as are necessary, consistent with those extended to receivers in absentees’ estates.
