Dentons was founded in March 2013 by the merger of SNR Denton, Fraser Milner Casgrain and Salans. Following its merger with Chinese law firm Dacheng in November 2015, Dentons became the largest law firm in the world by number of lawyers and has the most offices of any law firm in the world.
As of April 2023, Dentons operated in 80+ countries and had 160+ offices. The firm has no headquarters, although the firm’s senior leadership are primarily based in London and Washington, D.C. Dentons is structured as a Swiss Verein called Dentons Group, which does not itself provide legal services.
