ยง  251. Authority for committee or conservator to compromise claims. A
  court exercising jurisdiction over the  property  of  a  person  with  a
  mental  illness,  or  conservatee  may,  upon  the  application  of  the
  committee of the property of such incompetent person or the  conservator
  of  the  conservatee,  and for good and sufficient cause shown, and upon
  such terms as it may direct, authorize the committee or  conservator  to
  sell,  compromise  or compound any claim or debt belonging to the estate
  of the incompetent person or conservatee. But such authority  shall  not
  prevent  any party interested in the trust estate, from showing upon the
  final accounting of such committee or  conservator  that  such  debt  or
  claim  was  fraudulently or negligently sold, compounded or compromised.
  The sale of any debt or claim heretofore made in good faith by any  such
  committee  or  conservator,  shall  be  valid,  subject, however, to the
  approval of the court, and the committee or conservator shall be charged
  with and liable for, as a part of the trust fund, any sum which might or
  ought to have been collected by him.
