Vinson & Elkins Opens Brussels Office with Hire of Antitrust Partner May Lyn Yuen

An experienced competition lawyer based in Brussels for over a decade, Yuen will expand the firm’s Antitrust transactional and dispute practices.

Vinson & Elkins today announced that it has opened an office in Brussels, led by Antitrust Partner May Lyn Yuen.

Qualified in both the EU and England & Wales, Yuen advises on multi-jurisdictional transactions and complex competition matters. She has significant experience leading global merger control strategies and represents clients in cartel, antitrust and EU Foreign Subsidies Regulation Investigations. She also regularly counsels clients on distribution issues and competitor collaborations.

“Our antitrust practice has earned a reputation for helping clients navigate their most consequential competition matters. Adding capability in Brussels reflects our commitment to both our cross-border investigations and transactional practices,” said Vinson & Elkins Chair Keith Fullenweider.

“May Lyn is highly recommended by some of our top clients and also highly endorsed by our partners who have worked with her in the past,” said Partner Hill Wellford, co-head of the Vinson & Elkins’ Antitrust group “Her deep experience and collaborative approach strengthen our ability to deliver practical, strategic counsel to clients facing complex competition issues, including major transactions and European Commission investigations of market conduct.”  

Brussels is home to the European Commission, one of the most influential competition authorities in the world, responsible for defining EU competition law policy and enforcing it across antitrust, mergers and State aid, as well as implementing the Digital Markets Act and the Foreign Subsidies Regulation. Vinson & Elkins’ new office is located in the heart of the city’s European Quarter and steps away from the European Commission.

Yuen joins Vinson & Elkins from Hogan Lovells, where she was a Brussels-based partner in the firm’s Antitrust and Competition practice. Before moving to Brussels over a decade ago, Yuen practiced in London. In addition to being registered as an EU lawyer with the Brussels Bar, Yuen is admitted as a Solicitor of England & Wales and serves as the Chair of the Law Society’s Competition Section Advisory Committee.  She has been recognized in Global Competition Review’s “Women in Antitrust” (2025) and Lexology’s Client Choice – Competition (2026). 

“Competition and regulatory scrutiny are increasingly global and complex, especially for companies operating across multiple jurisdictions,” Yuen said. “This is an exciting opportunity to help build the firm’s European presence from Brussels in collaboration with Vinson & Elkins’ well-established London office. I look forward to developing a transatlantic antitrust platform that reflects the firm’s excellence and ambition.”  

For more than 50 years, Vinson & Elkins’ Antitrust practice has guided clients through their most challenging competition law issues. The firm is ranked among the leading Antitrust and Cartel practices by Chambers Global (2019-2026); Chambers USA (Nationwide, 2025); and The Legal 500 US (Antitrust – Merger Control, 2018-2025).
