(1) The registration under this Act of the ownership of any estate or interest in land shall, on and after the date of registration, exempt that estate or interest from the provisions of the enactments relating to the Registry of Deeds; and a deed or other document relating to that estate or interest and executed or coming into operation on or after that date shall not, unless it also relates to unregistered land, require to be registered in the Registry of Deeds. The registration of such ownership shall not, however, have the effect of exempting from registration in the Registry of Deeds any deed or document relating to the title to any other estate or interest in the land other than a deed or document creating such estate or interest.

(2) Where the ownership of any estate or interest in land is registered under this Act, the Authority shall cause a record of the registration, in the prescribed form, to be registered in the Registry of Deeds free of any fee or duty.  

(3) When the registration in the Registry of Deeds of any deed or other document within a certain period or otherwise is required by any enactment, registration of the title under such deed or other document (within the same period, where registration within a certain period is required) shall be a compliance with the provisions of that enactment.
