Reis, Souza, Takeishi & Arsuffi Advogados
Dispute Resolution · Brazil
Qualified in Law and Business Administration, Marcos Hokumura Reis has more than 25 years’ practice experience in arbitration and cross-border disputes. As the Founding Partner of Reis, Souza, Takeishi & Arsuffi Advogados, he primarily acts as counsel in complex domestic and international arbitrations. He is further a member of the Arbitration Advisory Committee of the Brazilian Federal Bar Association and the Miami International Arbitration Society (MIAS) – as well as author of the books Arbitragem no Agronegócio and Gestão de Conflitos no Agronegócio. He was ranked by Análise Advocacia as a leading counsel in the agribusiness sector for the period spanning 2023–2025.
Mr Hokumura Reis commented: “Our day-to-day practice focuses on international arbitration and cross-border transactions, with specific emphasis on high-value disputes involving complex contractual and regulatory frameworks. We routinely advise clients from diverse jurisdictions on dispute resolution strategies, contract negotiation and risk allocation in international commercial operations. In arbitration, we represent parties before leading institutions, both as counsel and strategic advisers.
“I believe our work is distinguished by technical precision, strategic discipline and discretion. My dual academic background in Law and Business Administration allows me to address not only legal aspects, but also the underlying commercial rationale of each case. I remain personally involved in all mandates. As such, clients rely on our ability to anticipate litigation risks and manage cross-border dynamics with efficiency and clarity.”
Reis, Souza, Takeishi & Arsuffi Advogados is notable for representing international investors, financial institutions and Brazilian corporations engaged in large-scale transactions. Most matters involve substantial financial exposure, often with multi-jurisdictional implications. Clients receive a truly results-orientated that prioritises responsiveness and clear legal positioning.
To date, the firm has advised global commodity producers, institutional investors and listed companies in disputes involving joint ventures, M&A transactions and supply agreements. It recently acted for a Brazilian company in an arbitration seated in London under the LCIA Rules, involving a dispute with a foreign SPC over a terminated commercial alliance. The case raised issues of international contract formation, parallel proceedings in Brazil, as well as procedural coordination across jurisdictions. The outcome was that the arbitral tribunal ultimately upheld the client’s key claims.
Mr Hokumura Reis added: “Another recent matter involved defending a client against tactical litigation in multiple jurisdictions designed to delay arbitration. To this end, we coordinated with foreign counsel to obtain anti-suit measures – and pursued emergency relief before the arbitral tribunal. This case was also resolved without any interruption to the client’s operations.”
