Trust and reliability are the foundation of a strong partnership. That is why we listen to your needs, are available when you need us, and provide legal expertise and strategic advice of the highest quality and integrity.

For ten consecutive years, Thommessen has been recognized as the Norwegian law firm with the best legal expertise by the business community (Kantar Prospera 2024). This recognition forms a solid foundation as we help your business navigate complex legal landscapes, always considering the bigger picture—from commercial and societal needs to political and global perspectives.

Just as important as solving challenges is identifying opportunities. To provide you with the best strategic advice, we stay ahead by continuously improving our services, embracing innovation, and driving digital transformation. This ensures you receive solutions that create value and strengthen your competitive edge.

Since 2014, we have been at the forefront of project management in the legal industry, setting new standards along the way. By tailoring our team to your project and leveraging our collective expertise and capacity across the firm, we go beyond delivering legal advice. We are a strategic partner who helps you reach your goals in the best possible way. With Thommessen, you benefit from efficient work processes, optimal resource allocation, and cost predictability—while we maintain the highest standards of quality.
