Real Property Act 1886

In any such case, if only a portion of the land comprised in any certificate has been sold, and the whole of the arrears of rates, interest, and costs appear to be satisfied by the sale of the land transferred, a statement to that effect shall be appended to the transfer, signed by the Master or other officer of the Court acting in that behalf; and thereupon the Registrar-General shall make an entry on the partially cancelled certificate in the Register Book, discharging the memorial of the order entered thereon.
