21. Powers of attorney
(1) A person may by power of attorney in a form approved by the Registrar appoint some person to be his attorney for any purpose in relation to his interest in any stock (including an application for conversion or to receive interest or redemption money) but if the power purports to confer authority to deal on behalf of persons holding stock jointly it must be executed by all the owners of that stock.
(2) If the Registrar is satisfied that a power of attorney has been properly executed and attested and that the signatures thereto are genuine, and is of the opinion that it contains a power appropriate to the purpose, the Registrar may act upon the authority contained therein for that purpose in relation to stock.
(3) The Registrar may require a power of attorney to be left at the Registry at least 2 clear days before it is acted upon.
(4) Particulars of every power of attorney left at the Registry for notation shall be entered by the Registrar in a register.
(5) A power of attorney shall be valid and effectual for all purposes therein mentioned until notice of its revocation or of the death, bankruptcy, insolvency, or unsoundness of mind of the donor of the power has been received by the Registrar.
