He is regularly trusted by clients with managing the conduct and resolution of high value and strategic disputes, including through international arbitration, superior Court litigation and other forms of alternative dispute resolution.
David is highly valued for his careful and thoughtful approach to matters, along with his tireless and enthusiastic commitment to achieving the best possible outcome for his clients.
David is held in very high regard by his clients and peers, as demonstrated by him being currently listed in Legal 500, Chambers Asia Pacific and the 'Best Lawyer List' for various forms of dispute resolution (including arbitration and litigation). He receives high praise from interviewees, clients finding him "an effective communicator who is always available" and "great to work with and on top of all the issues," while another source calls him "a master of litigation warfare" who is "laser-focused on helping the client and getting the best outcome - and always delivers." (Chambers Asia Pacific, 2022); and "David Jenaway is a clear stand out. His legal skills are exemplary. He is able to combine these skills with a tenacious approach to understanding and implementing his client’s needs. He delivers on big matters and is certainly someone you want in the trenches with you." (Legal 500, 2024).
