Registrar, as the case may be, a statutory declaration, in the form in the Third Schedule, stating the date of the bill of sale and of the last registration thereof, the names, residences and occupations of the parties thereto as stated therein, the names, residences and occupations of the parties to each transfer or assignment, and that such bill of sale is still a subsisting security, and shall also produce at the same time to the Registrar or Assistant Registrar, as the case may be, such transfer or assignment; otherwise such transfer or assignment shall be void.
