Section 381. Survey, map or plan to be filed

There shall be filed with the
  registrar a survey, map or plan of the land the title to which is sought
  to be registered, which shall be made by a competent surveyor and  shall
  be  subject  to  the approval of the court, and which shall clearly show
  the exact boundaries of the land and its connection with adjacent  lands
  and  any adjoining or neighboring streets and avenues, and the distances
  from  such  adjoining  or  neighboring  streets  or  avenues,  and   all
  encroachments,  if  any,  and all other facts which are usually shown by
  accurate surveys. If any adjacent land is already registered, the survey
  must properly connect and harmonize with the survey of  such  previously
  registered  land.  There  shall be attached to such survey, map or plan,
  and filed with it, an affidavit of the surveyor by  whom  it  was  made,
  that  it  was  made by him personally or under his immediate supervision
  and direction; that it  is  a  survey,  map  or  plan  of  the  property
  described  in  the  petition or the official examiner's report of title,
  and that according to the best of his knowledge and belief said property
  is included in the boundaries shown on such survey, map or plan, without
  any encroachments or improper erections, except as  follows:    (stating
  and  describing  any  encroachments  or improper locations of buildings,
  fences or other structures). After  the  original  registration  of  any
  parcel  of  land,  a  new  survey,  map  or  plan  of the same showing a
  subdivision thereof into lots may be  filed  with  the  registrar  after
  compliance  with the provisions of section three hundred thirty-four and
  section three hundred thirty-five of the real property law, as  amended,
  and  chapter  six  hundred  twenty  of  the  laws  of  nineteen  hundred
  twenty-six. The filing of such a new survey, map or plan  shall  outline
  the  registered portion of the property, shall be noted as a memorial on
  the certificate of title to which it relates, and thereafter the land or
  any interest therein shall be transferred or encumbered by reference  to
  it;  in  the event that the old description is used, reference must also
  be made to the new map.
