UK Land Registration Act 2002 27: Dispositions required to be completed by registration

What does 27 require?

A transfer, the grant of a lease for more than seven years (or a reversionary or discontinuous lease and the other leases listed), the express grant or reservation of an easement or profit, a rentcharge, a right of entry, and the grant of a legal charge do not operate at law until the registration requirements in Schedule 2 are met: the disponee (or the chargee) must be entered as proprietor, and notices and entries for appurtenant rights must be made. Until registration the disposition takes effect in equity only.
