The Surveyor-General may, if the diagram of any piece of land entirely fails to represent that land or misrepresents it to such an extent that damage or loss might result to any person who acquires or may acquire any interest therein, give notice of that fact to the Registrar and to the owner thereof, after which no further registration of that piece of land or of any portion thereof or of any share therein may be effected in a deeds registry until a new diagram thereof has been approved, and the title deed thereof has been endorsed in accordance with the new diagram as prescribed by the Deeds Registries Act, 1937 (Act No. 47 of 1937), and if the Surveyor-General is unaware of the address of the owner of the piece of land, a publication of a notice in the prescribed manner shall be deemed to be sufficient notice to the owner for the purpose of this section.
