About Our Brussels Office

Established in 2003 and now home to more than 30 professionals, Sidley's Brussels office is a leader in helping companies, industry associations and governments navigate and shape EU rules. Our lawyers apply innovative strategies to help clients achieve their competitive business objectives. Sidley’s strength in the three cornerstones of EU law critical to global business – competition, international trade and EU regulatory law – allows us to craft solutions tailored to our clients’ legal and policy concerns.

“Sidley consistently provides us with strong advice across multiple jurisdictions.”
Chambers Europe-wide 2023, EU Competition

Our Brussels office lawyers offer a rare combination of private- and public-sector experience and have a sophisticated understanding of EU institutions and policies. We represent clients on a wide variety of matters before the European Commission, the European Parliament, the Council of Ministers, EU Member State authorities and the European Courts.

“They're very hands-on, they have a very good knowledge of the legal landscape and they are very smart lawyers with good ability to capture the technical complexity of legal issues.”
Chambers Europe-wide 2023, International Trade/WTO

Clients served by the Brussels office include global companies and trade associations active in the aviation/aerospace, biotechnology, chemicals, consumer electronics, cosmetics, energy, financial services, food, forestry products, media and broadcasting, medical devices, metal and minerals, motor vehicles, pharmaceuticals, telecommunications, and transportation sectors.  We have also represented many governments, including the European Commission, on a wide variety of matters.

“Sidley’s team is outstanding not only in terms of knowledge of EU (e.g. clinical trials, marketing authorizations, orphan designation) and national (e.g. pricing and reimbursement) regulatory matters, but also for their ability to deliver clear, pragmatic and fast advice on very complex affairs.
Legal 500 Belgium 2023, EU Regulatory: Pharma, Medical Devices and Biotech

Located in the heart of Brussels' "European Quarter," the office is home to a diverse group of international lawyers who are able to communicate with clients in a multitude of languages.
