Timothy Lyons QC

The early years of Timothy's career were spent doing general chancery work. He then spent a considerable time in revenue chambers and now deals with a wide range of public and commercial law matters. Particular areas of interest include:

  • Direct and indirect tax disputes (VAT, excise duty, national insurance) – including EU and international aspects;
  • Arbitrations under double tax and bilateral investment treaties.
  • EU customs duties; anti-dumping and countervailing duties;
  • Trade and WTO law – disputes and arbitrations;
  • General EU law – internal market (fundamental freedoms, state aid, public procurement); environment; external relations;
  • Private client – trusts, succession, conflict of laws, and taxation.

Timothy’s interest in international matters has led to him advising foreign governments as well as businesses and high net wealth individuals. He represents in court, and advises, trustees of both domestic and international trusts on a wide range of issues and is a member of STEP’s Cross-Border Estates Group and its EU Committee.

Timothy has been called to the  Bar of the Republic of Ireland (1998) and is also a member of the London Court of International Arbitration.
