Section 1742. Appraisal

When  the  court  deems  it  necessary  for  the
  protection of  the  interests  of  the  infant,  incompetent  person  or
  conservatee,  it  may  appoint  a  competent,  disinterested  person  as
  appraiser, who  after  taking  an  oath  fairly  to  appraise  the  real
  property,  shall  go  upon  the  premises,  and make an appraisal of the
  property and report the result thereof to the  court.  The  fee  of  the
  appraiser  shall  be  fixed by the court and be included in the costs of
  the proceedings. A transcript of the proof and the report of the referee
  or appraiser, if any, shall be filed with the final order.
