Helen Conybeare Williams is a solicitor advocate in London, whose practice is focused on international dispute resolution, as well as contract advice and representation prior to arbitration or litigation, in complex technical cross border disputes.

She has conducted complex international commercial arbitration matters worldwide on behalf of major multi-nationals across a broad range of industries, namely shipbuilding and offshore oil and gas (related to marine construction, drilling and exploration agreements), construction and  engineering of major capital projects (including power plants, gas and water pipelines, highways, irrigation, hydroelectric and desalination plants, ports and airports), hotels (including development, management and franchise agreements) manufacturing and supply of industrial plant and machinery, and healthcare (distribution and license agreements).

She has conducted international commercial arbitration proceedings under the rules of major arbitration institutions, in particular the International Chamber of Commerce (ICC), the London Court of International Arbitration (LCIA) and London Maritime Arbitrators Association (LMAA), as well as under UNCITRAL rules. She has conducted such disputes throughout Europe, the Middle East, and the Asia-Pacific region.

She also represents clients in litigation in the courts of England and Wales, including in arbitration appeals and enforcement issues.

Helen has advised on the selection of jurisdiction clauses and dispute resolution mechanisms, and is experienced in drafting the relevant clauses.
