Paul was called to the Bar in 1975 and commenced practice in specialist chambers, later known as Falcon Chambers. He took silk in 1992. Throughout his career at the Bar, he specialised in property law but his practice included many connected areas of law, such as insolvency and professional negligence. His work involved a high volume of litigation and court appearances at first instance, principally in the Chancery Division and in the County Courts, but often in the Court of Appeal and on six occasions in the House of Lords. He frequently appeared as counsel in arbitrations involving the valuation of property (both rental and capital valuations) or involving agricultural land.
