Who’s Who Legal Asset Recovery: Lawyers

James Maton is exceptional — a genuine standout and one of the most capable lawyers we have worked with. He combines first-rate technical command with complete control over the process: nothing slips, nothing is left to chance, and he is always several moves ahead. He is calm under pressure, precise in his advice, and unfailingly professional in how he handles both us and the other side. What we value most is his judgment. He knows when to push and when to hold, and he gives a clear, confident steer at exactly the moments that matter. He commands real respect — from clients and opponents alike — and he sets the standard for the rest of the team. He is, in every sense, a true professional at the top of his game.
