Who we are
Seven Summits Arbitration (7SA) is a disputes specialist firm dedicated to international arbitration. The collective experience of our partners covers all major industry sectors and the entire arbitral process. They have acted as counsel in high-stake disputes, served as arbitrator and tribunal assistant, and headed a team at the ICC International Court of Arbitration, the world’s leading arbitral institution.

After additional years with leading dispute resolution practices in Germany, they reunited in Munich in 2017 to establish 7SA—a modern firm offering high quality legal services at competitive rates.
7SA combines the expertise and cross-border track-record clients expect from a leading international law firm with the flexibility and efficiency of a boutique practice. Passion and perseverance are the core values of 7SA, and our lawyers excel at responding to your needs.
