We offer comprehensive legal services relating to the resolution of business disputes through arbitration, domestic litigation and alternative dispute settlement mechanisms. We also advise on cross-border transactions with a focus on international and domestic trade and corporate law, as well as on international investment law and public international law.

Alternative Dispute Resolution

Alternative Dispute Resolution (ADR) refers to methods and processes for resolving legal disputes outside of traditional litigation through the court system and outside of arbitration. ADR methods include a range of different techniques, such as mediation, conciliation, and negotiation, and offer several advantages, including cost savings, quicker resolutions, and more control over the outcome.

Our Experience

We have been assisting our clients as counsel in commercial, corporate, and investor-State disputes through various ADR processes, including negotiation, mediation, conciliation, and expert proceedings. These ADR processes can be ad hoc or conducted under the rules of an institution, such as the ICC, DIS, or ICSID. Our industry experience includes international sales and distribution, real estate, new technologies, banking & finance, and transportation.

One of the partners of the firm, Philipp Wagner, is a certified mediator and regularly serves as mediator with a focus on corporate and commercial conflicts.

Our Offer

Our ADR services include:

  • Identifying possible ADR options for a specific dispute
  • Coordination with third party funders (if required)
  • Representation in ADR processes
