International Arbitration

In today’s globalised economy, international arbitration has become one of the most effective tools to resolve international business disputes. Rely on our multidisciplinary team to offer you tailor-made advice and guide you through the entire international arbitration process.

Tailor-made advice

Our wide range of legal expertise allows us to put together a team that is highly tailored to the needs of your business dispute, taking into account local and international laws, language prerequisites, and any required industry-specific expertise. You can be assured that, throughout the entire arbitration process, we will always keep your business interests in mind.

International focus

We are specialised in the resolution of disputes under the laws of our four home markets: the Netherlands, Belgium, Luxembourg and Switzerland. To offer our international clients the best possible advice, we can also rely on our extensive global network through our offices in London, New York, Paris, Hong-Kong, Singapore and Tokyo, our dedicated region teams, and our network of top-tier local advisers.

Our international arbitration lawyers routinely act in (commercial or investment-treaty) international arbitration proceedings, either ad hoc or under the auspices of all major arbitral institutions (ICC, ICSID, LCIA, SIAC, NAI, Swiss Chambers, Cepani, etc.).

Our track record

Many of our clients are internationally active companies, states or sovereign entities, or private or public investors with substantial and growing cross-border activity. They rely on us for all types of arbitration-related proceedings (injunctive relief, setting aside, enforcement) brought before the State courts of our four home jurisdictions (the Netherlands, Belgium, Luxembourg and Switzerland). Our team has acted in many high-profile international arbitration cases, setting aside proceedings, and enforcement proceedings, and is praised by both peers and clients.
