Brussels Office

Our Brussels office offers solutions-driven advice to our clients as they face an increasingly complex and evolving legal landscape in the wake of the United Kingdom’s exit from the European Union and heightened global regulation of digital and technology companies. Complementing our presence in London, our Brussels-based lawyers collaborate closely with the Firm’s broader Antitrust and Trade Regulation Practice, our Litigation Department and our transactional practices to provide clients with the local expertise of a Europe-based team combined with the comprehensive resources of a global firm. Our lawyers have advised some of the world’s most sophisticated companies across a broad range of antitrust and competition-related issues, including advising on regulatory approvals for major transactions; high-stakes litigation and investigations; and ongoing risk management and counseling.

“The team holds vast knowledge of antitrust law and global regulations, alongside valuable commercial experience.”
Chambers USA (quoting a client)
