Three Stone is a well-regarded Chancery commercial set. In recent news, Stephen Woodward joined chambers having previously worked at Withers LLP and Payne Hicks Beach where he was a partner in its private client department. The clerks are ‘approachable, commercially aware, and very responsive’. Senior clerk Justin Brown and deputy senior clerk Gary Bateman ‘never fail to deliver’. First junior Steve Anten and second junior Frank Lee are ‘standout’ clerks. ‘They are genuine team players and nothing is ever too much trouble – first class.’ Offices in: London


Three Stone is a merger between the members of highly regarded sets 13 Old Square Chambers and 3 Stone Buildings to form one set of chambers called Three Stone. The merger has been widely reported in the legal press.

The set: Three Stone has always focused on commercial chancery, with specialisms in particular in commercial actions, insurance and reinsurance, insolvency and restructuring, commercial trusts, trusts of land, property work, traditional chancery work, and taxation. Two members have developed high-quality public international law practices. Chambers also has an established IP practice and this has developed in tandem with expertise in sports, media and entertainment and has been augmented by the recruitment of competition specialists.

A highly efficient set of barristers, committed to delivering excellence to clients in accordance with the best traditions of the Bar, chambers has developed a substantial offshore reputation and practice. Two members are admitted in New York, other members have appeared regularly in Hong Kong, have been admitted ad hoc to appear in cases in the Cayman Islands, as well as in the Caribbean jurisdictions, Isle of Man, Eire and Northern Ireland. The set’s presence offshore is also growing, with connections in Guernsey and Jersey.

Chambers’ client base ranges from Magic Circle to high-street firms, with strong regional connections to the Midlands and the North West. Instructions are received directly from firms in the Channel Islands, the Caribbean, Hong Kong and New York, and in the past year the volume of work undertaken has increased significantly, requiring chambers to recruit a number of new, highly experienced members.

Types of work undertaken: Members of chambers conduct a wide range of litigious and advisory work in most offshore jurisdictions and accept instructions from foreign clients who have no established relationship with English solicitors. Members’ expertise in commercial litigation, banking and finance, insolvency, trust law and the land laws of other jurisdictions, and extensive experience of interim remedies and as trial lawyers, are particularly valuable.

All members of Three Stone are accustomed to advising and appearing in mediations and arbitrations, and individual members have been engaged in some substantial arbitrations in recent years. Three Stone’s members are all regularly retained in mediations either as advocates or mediators. The set’s involvement includes English, European and international procedures, with a substantially increasing practice in Anglo-American proceedings conducted in the US, the UK and elsewhere around the world – members also act as experts on English law in alternative dispute procedures conducted by foreign lawyers.

Three Stone is able to accept instructions across an extensive range of law, including arbitration; art (cultural property); banking and financial regulation litigation; charities; civil fraud (asset tracing and recovery); commercial disputes and litigation; company law; competition law; conflict of laws; construction; Court of Protection (powers of attorney); entertainment (media and sports); financial regulation; insolvency and restructuring; insurance/reinsurance; intellectual property; mediation and ADR; offshore; partnership; pensions; professional liability; property; public international law; regulatory; taxation; trusts (trusts of land); and wills, probate and family provision.
