(1) Interests appearing in the register shall have priority according to the order in which the instruments which led to their registration were presented to the registry, irrespective of the dates of the instruments and although the actual entry in the register may be delayed.
However, where an instrument is prepared in the Registry it shall be deemed to have been presented on the date on which application for its preparation was made to the Registrar.
(2) Instruments sent by post or under cover and received during the hours of business shall be deemed to be presented simultaneously immediately before the closing of the office for business on that day, and instruments so sent but received between the time of closing and the next opening of the office for business shall be deemed to be presented simultaneously immediately after such opening.
(3) Where more than one instrument or application are presented on the same day, or on different days but at so short an interval from each other that in the opinion of the Registrar there is doubt as to their order of priority, the Registrar may refuse registration until he or she has heard and determined the rights of the parties interested thereunder.
