This book is a collection of papers given at the seventh biennial conference held at the University of Cambridge in March 2008, and is the fifth in the series Modern Studies in Property Law. The Property Law conference has become well-known as a unique opportunity for property lawyers to meet and confer both formally and informally. This volume is a refereed and revised selection of the papers given there. It covers a broad range of topics of immediate importance, not only in domestic law but also on a worldwide scale.
