Section 420. Enforcement of mortgages, charges, liens and incumbrances

All
  charges, liens and  incumbrances  on  registered  property,  or  on  any
  estate,  right  or  interest  in the same, and all rights therein may be
  enforced as now allowed by law; and  all  laws  with  reference  to  the
  foreclosure,  release  or  satisfaction  of  mortgages  shall  apply  to
  mortgages on registered property or on any  estate,  right  or  interest
  therein,  except  as  herein  otherwise  provided, and except that until
  notice of the pendency of any suit to  enforce  such  mortgage,  charge,
  lien  or  incumbrance  is filed in the registrar's office and a memorial
  thereof entered on the certificate in the title book,  the  pendency  of
  such  suit shall not be notice to the registrar or to any person dealing
  with the property or any right or interest therein. Upon the sale  under
  foreclosure  or  other  action  or proceeding directing the sale of real
  property, the title to which is then a registered title, it shall be the
  duty of the officer making the sale to report such sale to  the  justice
  assigned  to  the  "title part" of the special term, who shall thereupon
  designate an official examiner of title to examine into  the  action  or
  proceeding  or  any other fact or circumstance affecting the title since
  the last registration thereof. The examiner of title shall  prepare  his
  report  immediately  and  shall file one copy with the court designating
  him and one copy with the officer making the sale.  The  officer  making
  the  sale  shall  not  deliver  a  deed  of  the property sold until the
  examiner's report is filed with him showing the regularity of  the  acts
  and  proceedings  subsequent  to  the  last  registration  of title. The
  justice of the "title part" shall upon the production of the  deed  from
  the  officer making the sale and upon the report of the examiner approve
  said deed and make an order directing  the  registrar  to  register  the
  title  accordingly.  The  fees for the services of the official examiner
  under this section shall not exceed the sum of five  dollars  unless  an
  additional allowance is directed by the justice of the "title part."
