Sorainen stands out for its breadth of arbitration expertise. The team 'combines strong technical expertise with strategic thinking and practical execution' and has an excellent reputation for appearing in high-profile investment arbitration cases, especially Maria Pihlak, who clients praise as 'a true international arbitration practitioner in Estonia'. Contentious matters are also prominent in the group's workload; Kadri Härginen routinely acts on public procurement disputes, Triin Toom handles corporate and financial litigation, and Carri Ginter and Mari Agarmaa-Jentson assist with bankruptcy disputes. Cross-border energy disputes are another key area of instruction for the team. Pihlak, Härginen, and Ginter co-head the practice with Allar Jõks and Norman Aas.
