'Registered land' is short-hand way of writing 'land over which there exists at least one registered title. It's a rather sloppy term, because it is the InterestInLand that is registered, not the physical land itself. This has to be the case, because the same plot of land may be subject to more than one registered title -- a Freehold and a Leasehold may exist at the same time, for example. Owing to the extension ofcompulsory registration to the whole of England and Wales, the proportion of land which is registered in now increasing rapidly. Current about 80% is registered.
