MATTAR’s arbitration team comprises lawyers 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 lawyers’ work spans pre-dispute advisory, complex negotiations, and the representation of 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).

We advise clients on the resolution of judicial and administrative disputes, acting at both the pre-litigation stage and before courts and administrative bodies. With a focus on strategic conflicts, our team is committed to delivering excellence — combining agility, technical expertise, and a drive for the best outcomes for our clients, both from a procedural-strategic and a business perspective.

Our lawyers have worked across a broad range of areas, with particular emphasis on commercial, corporate, and banking law, capital markets, financial markets, litigation finance, and regulatory matters before the Brazilian Securities and Exchange Commission (CVM), the Central Bank of Brazil (Bacen), and the National Financial System Appeals Council (CRSFN).

Having been involved in some of the most significant and complex restructurings carried out in Brazil since the enactment of Law No. 11,101/2005, our team has built extensive experience conducting contentious insolvency proceedings and structuring, negotiating, and implementing solutions for both debtors and creditors in judicial reorganizations, out-of-court restructurings, and bankruptcy proceedings. Our practice covers high-complexity litigation, the development of viable restructuring plans, and the enforcement of pre-existing or newly created security interests in connection with financings extended to companies undergoing judicial reorganization.

The MATTAR team is composed of professionals who combine deep expertise in corporate insolvency with experience in high-complexity litigation and a solid grounding in corporate law and M&A and financing transactions. This multidisciplinary profile enables us to provide precise, technically sound advice both in crafting structured solutions and in deploying the litigation strategies required to safeguard the best interests of our clients.

We advise companies, economic groups, investment funds, and entrepreneurs at every stage of corporate transactions and mergers and acquisitions — from structuring and negotiation through closing and post-transaction integration. Our practice covers acquisitions and divestitures, corporate reorganizations, joint ventures, shareholders’ agreements, and corporate governance, with experience in both domestic and highly complex cross-border transactions.

Our team combines refined legal expertise with business acumen, delivering strategic and efficient advice at each stage of the transaction. We work in close coordination with our restructuring and insolvency, capital markets, and tax teams, ensuring that the proposed solutions are legally robust and aligned with our clients’ objectives.
