Our team of over 100 lawyers in our Brussels and Antwerp offices provides a full legal service to leading local and international corporations, financial institutions and public entities.

Belgian Law Firm of the Year (Chambers Europe award 2022)

Having been in the market for more than 40 years, our Belgian clients appreciate our natural understanding of their industry and background. International clients come to us for our knowledge of the 'ins and outs' of doing business in Belgium.

The majority of our work is complex, large scale, urgent and international in nature. Unlike the majority of law firms in Belgium we provide clients with a full service covering: corporate, M&A, finance, litigation, commercial contracts, employment and benefits, intellectual property, IT, outsourcing, real estate, tax, environment, EU and competition and public law, and are consistently ranked first tier across most of these areas. This means our clients receive relevant, commercial advice with all perspectives integrated, without the need to piece together a jigsaw puzzle of input from different law firms.

Clients benefit from our seamless integration across legal practice areas and into Allen & Overy's international network, ensuring the sharing of knowledge, information, technology systems, processes and skills.
