An executor, administrator, guardian, receiver, or other fiduciary appointed by or acting pursuant to the authority of any chancery court may sell, assign, or transfer any note, bill of exchange, bond, stock certificate, or other negotiable paper belonging to the estate committed or entrusted to him by such court under the standard of care applicable to trustees as set forth in Section 91-8-101 et seq. If the exercise of power concerning the estate is improper, the personal representative is liable to interested persons for damage or loss resulting from breach of his fiduciary duty to the same extent as a trustee of an express trust under the Mississippi Uniform Trust Code.
