(1) The register shall be conclusive evidence of the title of the owner to the land as appearing on the register and of any right, privilege, appurtenance or burden as appearing thereon; and such title shall not, in the absence of actual fraud, be in any way affected in consequence of such owner having notice of any deed, document, or matter relating to the land; but nothing in this Act shall interfere with the jurisdiction of any court of competent jurisdiction based on the ground of actual fraud or mistake, and the court may upon such ground make an order directing the register to be rectified in such manner and on such terms as it thinks just.

(2) The validity of registration of ownership of unregistered land shall not be affected by reason that the person thereby shown to be registered as owner was then dead and any person who proves to the satisfaction of the Authority that he is entitled to the land may be registered as owner thereof.
