Cox, who is expected to join the US firm in March, will bring the total partner headcount in the London office to five following last month’s capture of Weil Gotshal & Manges restructuring partner Tony Horspool.
The office was set up in October 2009 by former Freshfields and White & Case finance duo Maurice Allen and Mike Goetz.
Speaking about Cox’s appointment, Allen said: “He has a mixed practice acting for private equity houses and on the bank side. He’s a good fit with us and a very populr guy. Clients like him and associates like him.”
Cox had worked alongside Horspool at Weil before joining Freshfields.
Ropes & Gray is continuing to build its London offering, with the firm focusing its attention on its banking and finance practices in particular.
