In the following pages the Who's Who Legal team draws upon a decade of independent research to highlight the world's 70 leading law practices. Selection for the Who's Who Legal '70' was based on law firms' overall performance in the research. While our focus throughout was on individual lawyers, we have used the results to assess each firm's performance across all areas of work and across all offices. Of over 2,000 firms listed in this publication, only 70 have the required depth and breadth of talent to be featured here. We list firms alphabetically with an explanation of how they came to be selected - we commend them all for assembling remarkable teams of legal talent.
