Mark is recognised as a leading arbitration practitioner, having appeared as counsel or arbitrator in over 100 cases around the world and across the Asia-Pacific. Many of the cases have been ground-breaking; have often raised novel and complex issues requiring innovative solutions; and routinely involve some of the world’s leading corporations, sovereign governments, and state-owned entities.  After having practiced arbitration with leading international law firms for over 20 years, Mark was a founding partner of Lindsay Francis & Mangan (LFM) in early 2024. 

Mark has been engaged as counsel on disputes across a broad range of industries, under the laws of both common and civil law countries, on cases seated in many of the leading centres of arbitration (including Paris, London, Geneva, Stockholm, New York, Hong Kong, Tokyo and Singapore), and often with co-counsel.  Mark also regularly sits as an arbitrator.  He is a current member of the ICC International Court of Arbitration; an author of a leading treatise on Singapore arbitration published by Oxford University Press (3rd edition forthcoming); an author/co-editor of a book on investment treaty arbitration published by Global Arbitration Review (GAR) (3rd edition, 2025); and author of over 50 published articles, chapters and case commentaries on international commercial arbitration, investment treaty disputes and sports arbitration.

Chambers Asia Pacific has reported one client attesting: ‘He is brilliant and always finds the best solutions instantly', while Legal 500 has noted: 'The intellect of the team is unrivalled. They are trusted by clients with some of the largest disputes arbitrated in Asia.’  Mark's team was awarded International Arbitration Team of the Year in Southeast Asia by Legal 500 for 2020 and 2021. Mark has also been recognized twice in the Financial Times Innovative Lawyer Awards Asia Pacific (2017 and 2019); once in the GAR Awards (2023) for an article on how to reduce the environmental impact of arbitration; as a Who's Who Legal (now Lexology) Thought Leader since 2017; among Singapore's Best Lawyers since 2020; and as a Litigation star by Benchmark Litigation Asia Pacific (2026).  At firm level, LFM was awarded Asia Pacific Boutique Law Firm of the Year by the Benchmark Litigation 2024 in its first year of operation, while it was shortlisted in the Asia Legal Awards 2025 and in the 2026 GAR Awards in the 'Asian Practice that impressed' category.  LFM was added to the GAR 100 leading arbitration practices in the world in 2026.

  Legal 500 and Chambers have reported (based on interviews with clients and peers) that Mark is ‘a super cross-examiner’, 'incredibly hard working', 'a great advocate', ‘brilliant’, ‘a great strategist’, 'has an ability to assimilate a large amount of highly complex data', ‘always finds the best solutions’, 'remains cool under pressure', is ‘exceptional’, 'brilliant at tactics', ‘extremely sharp’ and 'excels at formulating and executing winning legal strategy consistent with the client's needs and objectives'. Mark is also described in these publications as 'superb', 'highly astute', 'innovative', 'hands-on', 'on top of things', ‘is really proactive as a thinker’, and 'has an encyclopedic knowledge of the SIAC rules and Singapore arbitration practice'.

  Legal 500 (2022) notes that: ‘Mark Mangan comes across as the hardest working lawyer in the business, he is just so incredibly well prepared. No stone is left unturned, even if only to be able to explain why an issue is irrelevant or a red herring. An exceptional lawyer. It adds: ‘The intellect of the team is unrivalled. They are trusted by clients with some of the largest disputes arbitrated in Asia.’

  Chambers (2022) reports that: ‘Clients find him to be “an extremely sharp and commercially minded lawyer who has excellent judgement and is very knowledgeable on Asian oil and gas disputes.”’ Similarly, Chambers (2023) records one observer saying: ‘They are extremely brilliant lawyers who have a thorough understanding of how arbitrations work, and the sort of things that tribunals value.’ It added in 2024: ‘He is brilliant and always finds the best solutions instantly.’
