Angeline Welsh KC

Angeline Welsh is a well-known and highly regarded arbitration expert having specialised in this field for well over a decade; described as “One of the leading arbitration focused juniors at the Bar” and “She is excellent on matters related to arbitration…”. Angeline is recognised as a Global Leader for Arbitration by Who’s Who Legal, having been recommended for some time as both a Thought Leader and Leading Junior at the English Bar for arbitration. In 2021 she was named by Chambers as International Arbitration Junior of the Year, and was previously named by Legal Week as a ‘Star at the Bar’ in recognition of her “excellent judgement and leadership qualities” and not being frightened to tackle novel and difficult areas of law, or “to deal head-on with the more complicated aspects of a case”.

Prior to moving to the English Bar at the end of 2015, Angeline was Counsel and Solicitor Advocate in the International Arbitration Group of a major international law firm, spending more than a decade in their London office, some of which was spent on secondment to the Hong Kong office and the LCIA Secretariat. She has worked with counsel in a wide range of jurisdictions including India, Myanmar, Indonesia, Belize, Hong Kong, Turks & Caicos Islands, Singapore, United States, Kazakhstan, Rwanda and various European states and on arbitrations (both commercial and investment treaty) under a broad range of institutional rules (ICSID, LCIA, ICC, HKIAC, UNCITRAL) and on an ad hoc basis. She is also admitted to the bars of Belize and the British Virgin Islands.

Angeline is currently Vice Chair of the IBA Arbitration Committee and serves on the ICC UK Selections Subcommittee. She regularly speaks and writes on the subject to arbitration law and procedure and is currently editing the 25th Ed of Russell on Arbitration, the leading textbook on English arbitration law.

Angeline actively accepts arbitral appointments. Since 2016, she has been appointed in over 20 arbitrations as sole, co-arbitrator or presiding arbitrator.
