Belgium is a central hub for European law, with Brussels serving as the base for major international institutions. The legal market is a sophisticated blend of “Magic Circle” global giants, powerhouse US firms, and prestigious independent Belgian firms.
Based on the 2026 Legal 500 and Chambers & Partners rankings, here are the top 10 law firms currently leading the Belgian market.
1. A&O Shearman
Following the landmark 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. 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.
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. Liedekerke
Liedekerke is arguably the premier independent Belgian law firm. Its core focus is local excellence with an international outlook. They are highly regarded for Commercial Litigation and Real Estate, making them the go-to for complex domestic projects and regulatory matters.

As one of the leading independent firms in the Benelux region, Stibbe offers a full-service approach. They are highly regarded for their Public Law, dispute resolution, and corporate expertise. They maintain a distinctively local culture while competing at the highest international level.
7. 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 Public Law work. Their reputation for technical precision in Belgian law is virtually unmatched.
8. 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 component, they are often the market leader.
9. Van Bael & Bellis
A dominant independent firm based in Brussels, Van Bael & Bellis is world-renowned for its expertise in EU Competition, Trade, and Regulatory Law. While they have a strong transactions practice, they are the specialized choice for matters involving international trade disputes.
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 from the Legal 500, advising both high-net-worth individuals and multinational corporations on the intricacies of the Belgian tax code.
