For nearly two centuries, Curtis has represented Latin American-based clients, as well as international clients doing business in the region. Established in 1991, Curtis’ Mexico City office was one of the first to be opened by an international firm in Mexico. Buenos Aires followed in 2011. Curtis’ Latin America practice is among the largest of any international law firm and is highly developed. It has an enviable track record of helping clients, including governments, state-owned entities, corporates and private individuals, achieve successful results in their transactions and disputes. The firm’s Latin America practice is particularly well known for its oil and gas, corporate, and arbitration focus.

The firm: Curtis, Mallet-Prevost, Colt & Mosle LLP, founded in New York in 1830, was one of the first US law firms to develop a truly international practice. The firm has always had an international outlook and a pioneering spirit: it remains the only US-headquartered firm licensed to operate in Oman and is the only law firm with offices in Turkmenistan. With 17 offices across the Americas, Europe, the Middle East and Central and East Asia, this internationalist tradition continues today.

Main areas of practice: Curtis represents Latin American governments and state-owned companies and advises internationally based clients on acquisitions and dispositions of assets and equity interests throughout Latin America. Its clients in the region operate across a broad range of industries, including oil and gas, metals, water, energy, industrial and consumer products, agriculture and food products, telecommunications, transportation, finance, media and tourism. The Latin America team has counseled on transactions in virtually every country in the region. All Curtis lawyers in Mexico City are bilingual and many hold law degrees from Latin American jurisdictions, placing Curtis in a unique position among international law firms. Its attorneys have intimate and first-hand knowledge of the region combined with experience advising on some of the largest transactions in Latin America. Curtis’ Mexico City office routinely draws upon the firm’s international network to provide full-service representation to clients in Latin America. The firm’s international arbitration practice is particularly strong in Mexico City precisely because Curtis utilizes this integrated team approach.

The Buenos Aires office advises clients on local and international matters in the fields of banking and financial services, agribusiness, real estate, project finance and infrastructure, joint ventures, mergers and acquisitions, investment management, venture capital, restructuring and litigation. Clients include domestic and foreign companies and individuals, commercial and investment banks, as well as governments and multilateral agencies.
