Dispute Resolution

Disputes present challenges for both the individuals and businesses involved. It is crucial to limit the dispute's impact on the day-to-day operations of the business, and to resolve the dispute without unnecessary strain on the relationships between the parties involved. With more than thirty lawyers, who plead a large number of cases before the courts and arbitral tribunals annually, our dispute resolution team commands a leading position on the Norwegian litigation and arbitration scene.

We have significant experience in resolving disputes both within and outside the judicial system. In our view, effective project management and strategic team selection are key to success. One of Thommessen's strengths is our extensive expertise across various fields. Our litigation specialists regularly work closely with industry and market experts, and you can be assured that we always engage the right expertise internally on the matter. Our goal is to achieve the best possible outcome, but the resources used must be proportionate to the case. Necessary expertise is therefore involved at the right time in the process. We take no shortcuts, but also no detours.

At Thommessen, we have around twenty lawyers admitted to litigate before the Supreme Court, and we regularly litigate before our nation's highest court. Several of our lawyers have also litigated cases before the EFTA Court and the European Court of Human Rights.

Our lawyers also have extensive experience in arbitration, both in Norway and internationally, and are often used as legal representatives and judges in international commercial disputes. We have experience from a range of arbitration institutes, including OCC, SCC, DIA, DIS, and ICC. Additionally, we have litigated and served as arbitrators in numerous ad hoc arbitrations, including under the arbitration rules of NOMA.

The law firm has a strong team of lawyers who are experienced in large and complex disputes. It is one of the largest law firms in Norway and can put together a team with the depth and breadth required. Client
