The principal part of Barry Denyer-Green's practice concerns compulsory purchase and compensation; his book on the subject, widely used by practitioners, is now in its ninth edition. He regularly appears in the Lands Tribunal, and has appeared in the Court of Appeal, the House of Lords and the Privy Council on cases concerning compensation issues.
He was chairman of the Compulsory Purchase Association in 2008-2009. His practice also includes other local government and public highways matters, as well as those concerning landlord and tenant, restrictive covenants, easements, common land, village greens, development agreements, and other aspects of land law and conveyancing.
