Execution of instruments

(1) Every instrument evidencing a disposition shall be executed by all persons shown by the register to be owners of the interest affected and by all other parties to the instrument, but the Registrar may dispense with execution by any particular party, other than the proprietors of the interests affected by a disposition where he considers that such execution is unnecessary. (2) Subject to section 122 (2), an instrument shall be deemed to have been executed only– (a) by a natural person, if signed by him; or (b) by a corporation– (i) if sealed with the common seal of the corporation affixed thereto in the presence of and attested by its clerk, secretary or other permanent officer and by a member of the board of directors, council or other governing body of the corporation; or (ii) in the case of a corporation not required by law to have a common seal, if signed by such persons as are authorised in that behalf by any law or by the statute or charter of the corporation or, in the absence of any express provision, by the person duly appointed in writing for that purpose by the corporation, evidence of which appointment has been produced to the satisfaction of the Registrar. 73
