Adverse possession and registered land are unlikely bedfellows—the one originating in the common law idea that a freehold estate results from possession and the other premised upon registration validating title. Indeed, when registration of title was introduced into England and Wales in the nineteenth century, acquisition of title to registered land by adverse possession was prohibited—see section 21 of the Land Transfer Act 1875. However, a more pragmatic approach then ensued, and the Land Registration Act 1925, s. 75, expansively provided that the Limitation Acts should apply to registered land in the same manner and to the same extent as those Acts applied to unregistered land. But technically, of course, this was impossible, and the section detailed a special trust mechanism for registered land alone. Section 75 thus clearly illustrates the inherent difficulties in trying to retain the substantive law of unregistered land within a registered context. Tensions are inevitable, because of the very different conceptual bases of the two systems. In Central London Commercial Estates Ltd. v. Kato Kagaku Ltd., The Times, 27 July 1998, Sedley J. was directly faced with such tension, as he strove to determine the effect of section 75.
