The Guide recognizes Curtis as a Leading Firm in Dispute Resolution and Corporate and M&A, both internationally and in Argentina and Mexico, alongside numerous individual recognitions for Curtis attorneys across jurisdictions and practice areas.

Latin America: International Firms - International Arbitration

Curtis' market-leading arbitration practice is known for representing states and state-owned entities in investment treaty and commercial arbitrations.

They have a knack for building close and trusting relationships with their clients."

Partner Elisa Botero is individually ranked in the Guide for her cross-border Latin America corporate practice; "Elisa knows how to handle Colombian idiosyncrasies well and mix them with the rigor of the U.S."

Argentina - Corporate and M&A

Based in Buenos Aires, Curtis has a significant Argentine presence, with a highly regarded corporate practice when it comes to advising buyers and sellers on complex transactions, joint ventures, and strategic alliances, among other corporate matters.

Partners Luis María Ayarragaray and Esteban Daireaux are Recommended Lawyers in the Guide. 

Client testimonials: 

  • "They excel in their specific knowledge of industry players, their active participation in various chambers of commerce and associations, and the close and constant dialogue between the firm's partners and clients. They facilitate direct access and coordination with the partners, enabling them to address and resolve issues quickly and effectively."
  • "Their strengths include commercial law and contracts, support in M&A processes, insolvency proceedings, and regulatory aspects of foreign trade and exchange controls. This practice requires in-depth knowledge of the industry in which they specialize; an area in which they have proven experience, serving large and well-known clients. It is essential not only to understand their clients but also their counterparties in a dynamic market with few players."
  • "Curtis, Mallet-Prevost, Colt & Mosle LLP in Argentina has extensive experience in agribusiness."
  • "They are people you can easily reach. It's easy to talk to them, and they're practically always available. You can tell they're interested in the topics and are prepared to provide support every step of the way."
