Section 13

in the case of a Brunei built ship, a builder's certificate, that is to say, a certificate signed by the builder of the ship, and containing a true account of the proper denomination and of the tonnage of the ship, as estimated by him, and of the time when and the place where she was built, and of the name of the person (if any) on whose account the ship was built, and if there has been any sale, the bill of sale under which the ship, or a share therein, has become vested in the applicant for registery;

in the case of foreign-built ship, the same evidence as in the case of a Brunei built ship, un-less the declarant who makes the declaration of ownership declares that the time and place of her building are unknown to him, or that the builder's certificate cannot be procured, in which case there shall be required only the bill of sale under which the ship, or a share therein, became vested in the applicant for registry; and

in the case of a ship condemned by any com-petent court, an official copy of the condemnation.
