Americas Practice Group Overview

An overview of Haynes and Boone's Americas Practice Group - its lawyers, practices, experience and accolades. >>


Haynes and Boone, SC, the firm’s fully integrated Mexico City office, was formed in 1994, and consists of approximately 20 attorneys 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 attorneys in the Mexico City office of Haynes and Boone 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 attorneys 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 (with two of them being 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.
