Latin America



Allen & Overy’s dedicated Latin America team combines our strength in project finance, general finance, corporate/M&A, capital markets and international dispute resolution with cultural familiarity and language skills to provide clients with highly effective service on Latin America transactions and dispute resolution and investigative matters.

The core of our team is based in New York, São Paulo and Washington, D.C., and we also draw on the talents of our outstanding group of lawyers in Tokyo, Seoul, Paris, Madrid, London and several other European and Asian cities.  We have many lawyers who are fluent in Spanish and Portuguese as well as lawyers qualified in New York, England and a number of other civil law jurisdictions.

Our practice focuses on finance, including banking,  projects, capital markets, derivatives, securitizations and structured finance more generally, as well as corporate matters, such as mergers and acquisitions, restructurings and insolvencies.  We advise our clients on transactions involving a variety of key sectors, including energy, oil and gas, other natural resources, infrastructure and telecommunications (including satellites). On the dispute resolution side, we focus on commercial and foreign investment arbitration as well as complex transnational litigation.

The breadth of our practice reflects the needs of our client base, which includes major financial institutions, sovereigns and regional and multinational corporations in Latin America, the United States, Europe and Asia.  Our multi-disciplinary and multi-jurisdictional capability ideally positions us to represent our clients in major cross-border investments and finance transactions in Latin America, as well as in major international disputes involving Latin American parties or that arise from transactions in the region.

Local knowledge

Our in-depth knowledge of the financial markets, different industry sectors and business environments throughout Latin America enables us to tailor our services to meet the needs of our clients and to manage each project swiftly and in a cost-effective manner. When necessary, we work with local law firms across the region.  We have developed close relationships with the leading law firms in each country where we do not have our own office and work seamlessly with these law firms.

International associates program

Allen & Overy's international associates program draws on our relationships with leading local law firms and companies throughout the region, allowing selected attorneys to spend ten to twelve months in the New York or Washington, D.C. office as fully integrated members of our team. We typically have at least two, and at times more, international attorneys with us in New York and Washington, D.C.  In recent years, our team has included international associates from Argentina, Brazil, Chile, Colombia, Mexico, Panama, Peru and Uruguay.

Our culture

Allen & Overy operates as a fully integrated firm and our one-firm ethos binds together all our lawyers, offices and practice groups. Allen & Overy’s integrated-team approach has won us a number of awards and continues to be key to our success. Allen & Overy stands by the values of understanding our clients’ businesses, anticipating their needs and working with them to facilitate and guarantee innovative and successful transactions. We take pride in treating every transaction as a top priority and are dedicated to providing clients with outstanding strategic legal advice.
