(1) If the Registrar in his or her discretion considers it desirable to indicate on a filed plan, or otherwise to define in the register, the precise position of the boundaries of a parcel or any parts thereof, or if any interested person makes application to the Registrar, the Registrar shall give notice to the owners and occupiers of the land adjoining the boundaries in question of the intention to ascertain and fix the boundaries.
(2) The Registrar shall, after giving all persons appearing by the register to be affected an opportunity of being heard, cause to be defined by a survey the precise position of the boundaries in question, file a plan containing the necessary particulars and make a note in the register that the boundaries have been fixed, and thereupon the plan shall be deemed to define accurately the boundaries of the parcel.
