This commentary on tenancy presents the entire law of tenancy in a systematic, reliable and up-to-date manner and is specifically designed for the daily legal practice. Legislation, case law, particularly the case law of the high courts, and legal literature up to April 2011 have been taken into account and thoroughly assessed. The commentary focuses on residential leases, but also considers tenancy with regard to commercial property, real estate and other objects, thereby providing the reader with commentary on the entire field of private tenancy law.
