Banking & Finance Disputes

We represent clients in all types of banking and financial market disputes, including regulatory enforcement proceedings before FINMA. We are also called as experts on Swiss law in financial market disputes before foreign courts. Our experience further includes assisting Swiss clients in relation to foreign financial market proceedings, including the instruction of foreign local counsel and the coordination of legal work in different jurisdictions. In addition, we represent clients in employment disputes between financial services companies and their directors, officers and employees. 

Our approach to banking & finance disputes

Our main focus is the representation of customers against the major Swiss banks. Further, we act for private banks and other financial institutions  as well as their directors, officers and employees. We know the strengths and weaknesses of all players and elaborate the most effective strategy for each case.

We regularly act for individuals in regulatory proceedings and have successfully defended such individuals before FINMA, the Swiss Federal Administrative Court and the Swiss Federal Supreme Court.

Our teams are designed to be lean and effective, with our partners actively involved at every stage, ensuring our clients receive top-tier service.

We are independent and conflict-free

As an independent law firm based in Switzerland, we have the liberty to collaborate with any advisor globally and serve as the central coordinator for all legal representatives involved in a strategy that spans multiple jurisdictions. Our lack of affiliation with any international networks or global offices allows us to partner with the most suitable lawyers for each specific dispute and work alongside our clients' existing advisors worldwide.

Our firm's independence and focus solely on dispute resolution enable us to take on cases that many other firms cannot, due to conflicts of interest. We are a preferred firm for conflict referral work, trusted by some of the world's largest law firms to protect their clients' interests. This trust cements our status as premier specialists in banking and finance disputes.
