This unique collection of essays, written by leading practitioners, policy makers and academics, looks at patterns of landlord and tenant law: past, present and future. Each sector is explored - commercial, long residential, housing, and agricultural - by taking a look backwards and forwards. The chapters explore the role that legislative, judicial, and policy developments, and market forces have played, and will continue to play, in shaping the law. Two chapters are devoted to the seminal case of Street v Mountford and its contemporary significance. A comparison is also made with the position in Australia and the United States. The book provides a scholarly reflection on the principles of leasehold law that will be of interest to practitioners, academics, and students of landlord and tenant law.
