Navigating the legal landscape in Belgium can be complex, especially since Brussels serves as the de facto capital of the European Union. Whether you are looking for local expertise or global reach, the Belgian market is home to some of the most prestigious law firms in the world.
Based on the 2026 Legal 500 and Chambers & Partners rankings, here is a look at the top 10 law firms currently leading the market in Belgium.
1. A&O Shearman
Following the historic merger of Allen & Overy and Shearman & Sterling, this firm has solidified its position at the absolute top of the Belgian market. They are renowned for handling high-stakes M&A and complex financial transactions. With deep roots in both Brussels and Antwerp, they offer a seamless bridge between Belgian law and international capital markets.
2. Linklaters
A “Magic Circle” titan, Linklaters remains a powerhouse for large-scale corporate work and cross-border litigation. Their Brussels office is particularly famous for its top-tier Competition and Antitrust practice, frequently representing global corporations before the European Commission.
3. Liedekerke
Liedekerke is arguably the premier independent Belgian law firm. Unlike the global giants, its core focus is local excellence with an international outlook. They recently secured top-tier rankings in Real Estate, Energy, and Environment, making them the go-to for complex domestic projects and regulatory matters.
4. Freshfields Bruckhaus Deringer
Freshfields is a consistent Band 1 performer in Belgium, specifically for Corporate/M&A and Tax. They are often the first choice for “blue-chip” Belgian companies and private equity houses looking for sophisticated cross-border advice.
5. Cleary Gottlieb Steen & Hamilton
Cleary Gottlieb is the “gold standard” for EU competition law. While their global reputation is immense, their Brussels office is deeply integrated into the local corporate fabric, often handling the most complex high-value M&A deals and government-related legal matters.
6. Stibbe
As one of the leading independent firms in the Benelux region, Stibbe offers a full-service approach. They are highly regarded for their administrative law, dispute resolution, and corporate expertise. They maintain a distinctively local culture while competing at the highest international level.
7. Loyens & Loeff
Specializing in the intersection of Law and Tax, Loyens & Loeff is a dominant force across the Benelux. They are particularly favored for investment fund structuring, real estate, and high-level tax litigation. If your legal needs have a heavy financial or tax component, they are often the market leader.
8. Eubelius
Eubelius is the largest independent law firm in Belgium. They have a massive footprint in the Belgian public sector and are frequently sought after for corporate governance, IPOs, and capital markets work. Their reputation for technical precision in Belgian law is virtually unmatched.
9. NautaDutilh
Another major player in the Benelux triangle (Belgium, Netherlands, Luxembourg), NautaDutilh excels in Banking and Finance. They are known for their pragmatic, business-oriented approach and are highly active in the fintech and life sciences sectors in Belgium.
10. Tiberghien
While many firms on this list are generalists, Tiberghien earns its spot as the definitive leader in Tax law. In 2026, they continue to hold a Tier 1 ranking, advising both high-net-worth individuals and multinational corporations on the intricacies of the Belgian and international tax codes.
