Land law, with its interlocking complexities and an abundance of technical terms, has always been one of the most difficult subjects for law students. From the first, the aim of this boo has been to explain the law in language that is as clear and direct as the subject permits. Originally written while these difficulties were still fresh in mind, the book now has the advantage of nearly fifty years in the practice of the law, coupled with Professor Thompson's wide experience of teaching and writing about the subject. In general scope and outline the book remains unchanged. Yet the whole of it has been reconsidered, and many improvements have been made in its balance, organization, layout and style. Much important new material generated by Parliament and the courts has been included, and over half the book has been rewritten or newly written, includingg a new chapter on licences and proprietary estoppel. The basic aim of directness and clarity remains unchanged.
