Recording of deed executed under a power of attorney

Where a deed is executed under a power of attorney, it shall be incumbent on the person who produces such deed for registration also to produce the power of attorney by the authority of which the deed produced purports to have been executed, and the Registrar shall not record the deed without recording the power of attorney, unless such power is already recorded at the time, and the execution of such power of attorney shall be proved in like manner as any other deed. 45
