Our team’s quality, tenacity, skill and experience has allowed us to achieve for our clients some of the largest and most significant awards in international arbitration and public international law. Indeed, Global Arbitration Review has remarked, “If any team has consistently brought home “the big results,” it seems to be Debevoise.”

Lawyers in the practice handle a broad range of matters, including international commercial and treaty arbitration, public international law and complex commercial litigation. Just as diverse is its industry experience, which spans energy, mining, manufacturing, pharmaceuticals, telecommunications, and many others.

Our team invests in each other to encourage an extraordinary degree of teamwork, mentorship, and support for diversity. This investment produces excellence today, and the diverse thought leaders and innovators of tomorrow.  It means our team members across generations are recognized as leaders in the major legal directories.

Debevoise lawyers also hold leadership roles with virtually every major arbitration body in the world. They do not just know today’s law; they are shaping tomorrow’s.

Flexible in approach, cost-effective and readily able to adjust resources to changing circumstances, the practice can efficiently meet the full range of client needs in high-stakes matters. Debevoise’s Protocol to Promote Efficiency in International Arbitration, first issued in 2010, has now become an industry benchmark.
