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, SIAC UNCITRAL and CAS. 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.

I am always very happy with Lenz & Staehelin's top-notch advice. They are the best lawyers in Switzerland to deal with these issues.

Chambers & Partners, 2025

Add incredible value, extremely engaged and really fight for their clients and able to offer pragmatic and win-win solutions. Result-oriented. Able to advise on very sensitive, complex and large matters and to deliver under time pressure.

The Legal 500, 2025

I have been very impressed by the technical strength of the team at all levels. The quality of the associates in the team supporting us day-to-day has been a standout.

The Legal 500, 2025

The team stands out for its convincing, well-thought out and innovative strategic thinking in complex arbitrations. It performs incredibly well even under pressure.

The Legal 500, 2025

L&S's litigation practice team is at the top of the food chain. They always add value through highly professional and efficient basic litigation work combined with innovative strategic and clever ideas. In addition, they have a deep technical and industry understanding. This combination leads to the best results without any additional burden on the in-house teams.

The Legal 500, 2025

Lenz & Staehelin offers a unique combination of a highly specialised, boutique-esque arbitration practice backed with the resources of a large, full-service firm. They have a truly global outlook and do not back down from cross-border challenges. A key capability is the ability to quickly learn the ropes of any industry, and employ that knowledge to build a pre-dispute and dispute strategy suited to the individual case.

The Legal 500, 2024

Very high quality work. Excellent reachability. Reliable and practical legal advice.
