Latin America/Caribbean

Haynes and Boone has one of the largest Latin America/Caribbean practices in the country and has been recognized by some of the leading market observers such as Chambers and Latin Lawyer for its work in the region. Approximately 50 lawyers comprise the firm’s Americas Practice Group working in Dallas, Houston, Mexico City, New York and Washington, D.C. Lawyers in the Americas Practice Group are native speakers or fluent in English, Spanish, Portuguese, and French and are comfortable working with civil law and international law concepts. As part of its Americas Practice Group, Haynes and Boone has formed a Cuba Team focused on international regulatory, transactional and dispute related areas to help clients monitor and prepare for new opportunities related to trade with Cuba.

Mexico City Office

Haynes and Boone, SC, the firm’s fully-integrated Mexico City office, was formed in 1994, and consists of approximately 20 lawyers and law clerks (including one U.S. expatriate partner and a senior counsel from Argentina). It employs the same technological resources as the U.S. offices of the firm. The firm is unique in having permanent senior Mexican lawyers based in its U.S. offices and conversely having an American expatriate working in its Mexico City office, thereby providing integrated working teams from both its U.S. and Mexican platforms.

The lawyers in Haynes and Boone's Mexico City office have unique experience which they apply on behalf of their clients. One partner formerly worked as lead Mexican counsel for the Mexico’s Bank Advisory Group during the Mexican debt restructuring of the 1980s. Another partner worked in the Pemex Legal Department working on financing matters in the energy sector. The U.S. expatriate partner is one of the few attorneys working in Mexico with international exploration and production experience. The Argentine senior counsel worked as in-house counsel at a major U.S. airline. Substantially all of the lawyers in the Mexico City office are bilingual and many of them have obtained post-graduate degrees in the U.S. and/or worked in the United States with a U.S. law firm (two are licensed to practice in the State of New York and one in the State of Texas). One of the firm’s first assignments in Mexico was advising the Mexican Government on the privatization of the downstream natural gas sector, an area of substantial sensitivity in Mexico.

Brazil Practice Group

Haynes and Boone has extensive experience in advising clients in cross-border matters involving Brazil, and in particular advising foreign companies investing in Brazil and in cross-border lending. We also have excellent experience advising Brazilian clients, as evidenced by our representation of MMX Mineração e Metálicos S.A. (MMX) in connection with the financing of an integrated iron-ore mining and infrastructure logistics project relating to MMX's Amapá mining facility, which was selected 2008 “Latin American Deal of the Year” by Trade Finance Magazine. In addition, leading industry publications such as Chambers Latin America 2013 and Latin Lawyer 250 (2011) have cited the Firm’s experience in Brazil. We have worked with a large number of the leading law firms in Brazil as part of our service to our clients and have had Brazilian foreign associates from several of these leading firms work with us in our offices.

Costa Rica Work

Haynes and Boone has been extremely active in Costa Rica in recent years. We have advised several important U.S. companies including American Airlines, Sabre, Hillwood, and a major oil and gas company in their investments in Costa Rica, having worked on more than a dozen projects in the country in recent years. The firm has been notably active in the Costa Rican real estate sector, particularly in the State of Guanacaste. We have also advised clients in acquisitions, joint ventures, financings, foreign direct investment, tax planning, real estate, litigation, technology contracts, and other matters. Haynes and Boone has worked with many of Costa Rica’s major law and accounting firms, and has been cited by both Latin Lawyer and Chambers Latin America for its work in the country. The firm has also been very active from an industry sector, having advised clients in the real estate, aviation, energy, and infrastructure areas, among others.

Experience in Other Areas of Latin America and the Caribbean 

In addition to its strong Mexican and Brazilian practices, the firm distinguishes itself with a strong presence in Central America, South America, and the Caribbean, having worked in over thirty jurisdictions in the region and through such work has developed a strong network of Latin American law firms. The firm is also a member of the multidisciplinary World Services Group, which has a strong network of Latin American law firms and other professional service providers, and Techlaw, an international network of law firms with strong technology practices. Haynes and Boone is frequently called upon to advise in complex multi-jurisdictional work in the region and leverages these relationships (in conjunction with its internal resources) well on behalf of its clients.

Latin American Attorneys on Staff in U.S. Offices

The firm has an active foreign associate program for leading Latin American and Spanish lawyers. The firm has hosted foreign associates from Argentina, Brazil, Colombia, Mexico, Peru, Spain, and Venezuela to work in its U.S. offices. In addition, we have a regular training program that provides an opportunity for our Mexican lawyers to work in one of our U.S. offices (typically Dallas or Houston) for up to one year. Finally, we regularly arrange for younger foreign lawyers to study on scholarship with the Center for American and International Law (formerly the Southwestern Legal Foundation) in Dallas, Texas, for an intensive six-week conference. The effect of these collective efforts is a dedicated and extensive international network of Latin American lawyers with whom we collaborate on projects in the region on behalf of our clients.


We actively write on important legal developments in the region. For instance, we publish the annual update on South American energy for the Matthew Bender Energy Law and Transaction treatise, and have published English and Spanish versions of Doing Business in Texas, a publication of the International Law Section of the State Bar of Texas focusing on in-bound considerations for foreign investors investing in Texas and the United States at large.
