Energy Disputes lawyers

International energy companies operate in complex and challenging environments. Investments in the energy sector are often high-value, high-risk transactions involving projects that rely on cutting edge technology. The progressive development of reserves and infrastructure around the globe, and the need for ongoing geographic diversification, has exposed energy companies to increased legal and political risk. Despite best business practices, in such an environment disputes may be unavoidable.

When disputes occur, energy companies expect their lawyers to be true specialists that understand the industry. The CMS Energy Disputes Team focuses entirely on advising and representing clients in the energy sector. Their experience covers all forms of dispute resolution, including international arbitration (both commercial and investor-state), litigation (either of the underlying dispute or in support of arbitral proceedings), expert determination, adjudication and mediation.

CMS is consistently ranked in the Global Arbitration Review ‘GAR30’ of the world’s busiest international arbitration practices and ranked by Legal Week in 2015 in the top 10 litigation firms by revenue. The CMS Energy Disputes Team has a recognised expertise and track record in high value and complex international arbitration and litigation in the energy sector.

As trusted advisors to numerous international energy companies, our energy disputes offering is truly global. We advise clients in the UK and across the world, from South America to the Far East, with significant recent experience in regions such as continental Europe, sub-Saharan Africa (for example, Angola, Cameroon, Congo, Madagascar, Nigeria), North Africa (including Algeria, Egypt, Morroco, Tunisia), the Russian Federation, the Middle East (including extensive experience in Iraq) and Brazil.
