21.—(1) This paragraph applies where any freehold estate or leasehold estate in unregistered land, being an estate (other than a mortgage) which is capable of being registered in the title register, is transferred by virtue of Article 14.
(2) Unless the transferee, or his successor in title or assign, has before the end of 6 months from the date of the transfer applied to be registered as owner of the estate, Article 14 shall be deemed never to have had effect to transfer the estate.
(3) In paragraphs (1) and (2) the expressions “freehold estate” and “leasehold estate” have the same meanings as in section 10 of the Land Registration Act (Northern Ireland) 1970.
(4) The power conferred by Part II of Schedule 2 to the Land Registration Act (Northern Ireland) 1970 (power of the Registrar of Titles to extend the period within which an application for first registration must be made) shall also apply in relation to the period mentioned in sub-paragraph (2).
(5) On an application for first registration under this paragraph, the applicant shall supply to the Registrar of Titles such information and produce to him such documents as he may require for the purpose of enabling him to deal with the application.
