Latin America: International firms > International arbitration

Foley Hoag LLP has an impressive background in defending Latin American states and state-owned entities in international arbitration proceedings, including state-to-state cases, investment arbitration and commercial disputes. The firm has a significant market share of sovereign state engagements in the arbitral sphere and it continues to gain and represent new Latin American sovereign clients in the area. It is also noted for its expertise in public international law. The firm launched its dedicated Latin America practice in 2021 with Clara Brillembourg (‘a brilliant leader’, ‘very effective and persuasive’) and Kenneth Figueroa (‘truly exceptional’) at the helm; both have extensive connections to Latin American states and outstanding track records in big-ticket cases. The team also includes an array of fluent Spanish and Portuguese speakers, some of whom were trained and qualified in Latin American jurisdictions. An ‘indispensable member of the teamChristina Beharry has ‘a deep mastery of quantum and damages issues’; she, along with dual-qualified (Nicaragua/New York) Ofilio Mayorga, who is based in New York and was raised to the partnership in August 2022; and counsel Gisela Paris (who is admitted in Argentina, New York and Washington DC), are all key figures in the Latin America focused arbitration practice group. Paris-based global co-chair of international litigation and arbitration Diana Paraguacuto-Mahéo provides further senior-level support; while head of the firm’s Africa arbitration practice, Tafadzwa Pasipanodya, also works on Latin America where clients highlight her ‘formidable legal mind’. All named individuals are based in Washington DC unless stated otherwise.

Foley Hoag for me is one of the or the best International Arbitration law firm that one can count on. A few years ago I had the opportunity to work with them in litigation and the truth is that their dedication, teamwork, attention to detail and, above all, analytical capacity to propose all the strategies in the case were beyond any standard. Lawyers like Ofilio Mayorga, Ken Figueroa are truly exceptional.

The team makes you feel that every case is unique. That your case is unique and that they are 1000% committed to its success although they may also be working on other cases, they make you feel like a unique client and that gives a lot of peace of mind as a client. In addition, the ability to coordinate and process information from different experts who are part of the team is extraordinary.

It’s a little excellent team, always pro active. They have extensive litigation experience, including cross-border lawsuits.

Foley Hoag specialises in representing respondent states in international arbitrations. This allows them to follow consistent and well-thought approaches, unlike other firms who may argue a certain position in one case and the completely opposite position in another case. Keeping a consistent approach across cases makes Foley Hoag a highly credible team who is well-respected by tribunals. Foley Hoag has obtained great outcomes for their clients, including complete victories for Uruguay, Nicaragua and Japan, among others. I highly recommend Foley Hoag to any States facing international arbitrations against them.

Clara Brillembourg is a brilliant leader at Foley Hoag. She is very effective and persuasive.

Christina Beharry has a deep mastery of quantum and damages issues and is an indispensable member of the Foley Hoag team.

Tafadzwa Pasipanodya is a formidable legal mind with a mastery of both the facts of the case and the applicable law.
