Litigation and Arbitration

Turning disputes into success

We combine decades of experience with creative thinking that’s forensically thorough. It’s the foundation for the civil, administrative and criminal litigation, international arbitration and high-profile corporate investigations that have made us a market leader. Whatever your sector or challenge, our talented team of over 50 dispute resolution lawyers can work both across the firm and borders delivering cost-effective, target-focused case handling.

Recognised as one of Switzerland’s leading M&A, takeover and shareholders’ litigators, we also act in banking and finance litigation for major corporations and individuals, as well as advise private clients on wealth management and inheritance disputes. And our Swiss footprint is large. It means we can defend our clients’ interests in all German- and French-speaking Cantons – also regularly delivering client success before the Swiss federal courts and administrative authorities, including Swiss Federal Supreme Court appeals.

Our experience in increasingly complex international arbitration is unique. It’s seen us involved in several hundred cases, acting either as counsel or arbitrators, conducted under all major arbitration rules including the ICC, Swiss Arbitration Centre, LCIA, UNCITRAL and SIAC. Our multilingual team can conduct cases in English, French, German, Italian and Spanish. Most of our lawyers have qualifications or practical experience in common law jurisdictions. A number of lawyers are also qualified to practise in foreign jurisdictions, including the US.
