Arbitration

MATTAR’s arbitration team comprises professionals specialized in domestic and international arbitral proceedings, with extensive experience representing leading clients in complex and strategic disputes across a wide range of sectors and industries, with a particular focus on corporate, contractual, banking, capital markets, and energy matters, including oil and gas.

Our professionals’ work spans from pre-dispute advisory through negotiations in high-value controversies, with a strong track record representing both domestic and foreign clients in arbitral proceedings seated in Brazil and abroad, administered by the world’s foremost arbitral institutions — including the International Court of Arbitration of the International Chamber of Commerce (ICC), the London Court of International Arbitration (LCIA), the Mediation and Arbitration Center of the Brazil-Canada Chamber of Commerce (CAM-CCBC), and the Market Arbitration Chamber (CAM), among others — as well as in ad hoc arbitrations conducted under the arbitration rules of the United Nations Commission on International Trade Law (UNCITRAL).

Our experience further includes ongoing advisory in highly strategic international arbitrations through partnerships with and in support of renowned foreign law firms, encompassing the preparation of memoranda, legal opinions, and analyses on specific questions of Brazilian law.
