Debevoise & Plimpton LLP


Debevoise & Plimpton LLP is a premier law firm with market-leading practices, a global perspective and strong New York roots. Our clients look to us to bring a distinctively high degree of quality, intensity and creativity to resolve legal challenges effectively and cost efficiently.

Approximately 650 lawyers work in nine offices across three continents, within integrated global practices, serving clients around the world.

The firm’s International Dispute Resolution Group is a global leader with an extraordinary win record that has racked up some of the largest awards in the world for its clients. The team has strong expertise in the energy sector, with a depth of experience few other firms can match. 

Debevoise has been active in international arbitration involving energy companies since the 1970s, when the firm represented two U.S. oil companies against the government of Libya resulting in a landmark award in the TOPCO case. In recent years, our team has won some of the largest awards ever issued in claims for breach of bilateral investment treaties (BITs). These include the first-ever significant BIT-related award, and the first BIT-related award in excess of $1 billion.

The group is keenly aware of and understands the varying strategies and risk appetites different clients have. That awareness and the team’s understanding of current trends in the energy sector enable it to represent a broad spectrum of clients – sovereign states, developers, public and private utilities, independent power producers, equity investors, monoline insurers, energy tech companies and lenders.
