Arbitration Chambers welcomes Marie Berard as our latest member with effect from 1 January 2027.

Marie joins following a distinguished 26-year career at Clifford Chance, where she led the firm’s London International Commercial Arbitration Group.

Widely respected, Marie has earned praise from peers and clients alike as a “massively experienced arbitration lawyer” and a “true expert in international arbitration”. She is particularly recognised for her work on high-value, complex international disputes across the energy, oil and gas, construction and financial services sectors.

Over nearly three decades in practice, Marie has built a formidable reputation, acting in arbitrations conducted under all major institutional rules and across a broad range of jurisdictions.

Marie has made a significant contribution to the international arbitration community and to the promotion of London as a leading arbitration centre. She sits on the LCIA Board of Directors and previously served as a member of the LCIA Court and as Vice President of the LCIA European Users’ Council.

Marie’s arrival follows the recent addition of Benjamin Hughes and further strengthens Arbitration Chambers’ position as the leading chambers for specialist international arbitration practitioners.

Welcoming Marie to Arbitration Chambers, Gavin Denton, Head of Chambers, said:

“Marie is widely recognised as one of the leading international arbitration practitioners in the UK and Europe, with an exceptional reputation built over nearly three decades. Marie brings a wealth of experience, sound judgement and a deep understanding of complex international disputes. She will be a wonderful addition to Chambers, and we are thrilled to have her join us.”

Marie will practice from Arbitration Chambers’ offices in London.
