Bregje Korthals Altes

Bregje Korthals Altes is a practical, hands-on, arbitration and litigation specialist with two decades of experience focusing on commercial disputes at the highest level. She thrives on helping clients navigate through high-stake disputes, where there are important interests at stake, whether legal, reputational, commercial and/or financial.

She has served as lead counsel and arbitrator in high profile commercial and construction arbitrations, under the ICC, UNCITRAL, NAI, CAM, and other arbitration rules. Recognized in the “Who’s Who” in the field of international arbitration for many years, Bregje’s experience spans a wide range of industries, including oil and gas, mining and minerals, civil engineering, aviation, IT and health tech.

A common theme in all her cases is that they all require a thorough understanding of  – often highly complex – technical issues, in addition to a full command of the facts and legal theories. Based on her interest of the specific dynamics in public-private relationships, Bregje has also gained broad experience in European Procurement Law and in the intense environment of public and parliamentary inquiries.

Before joining Ysquare in 2020, Bregje was partner in the litigation and arbitration group of De Brauw Blackstone Westbroek for many years. She was seconded to Schiphol National Airport and to the Ministry of Foreign Affairs in the Hague. Since 2018 she is a member of the board of the Netherlands Arbitration Institute.

Ysquare is founded on the idea that clients are best served by a team of professionals who take pleasure in delivering high quality legal services.
