A disposition of a registered estate (i.e. an estate in registered land) or registered charge that is required to be completed by registration under the Land Registration Act 2002 s 27. Such dispositions include transfers of the estate (e.g. a sale), the grant of a lease out of the estate for more than seven years, and the grant of a legal charge over the estate. If the registrable disposition is not registered as required, it fails to take effect at law - that is, the interest granted takes effect as an equitable interest only. Once a registrable disposition is registered, it is a registered disposition.
