Aziz & Kaye Business Law

Mexico > Competition and antitrust Tier 4

Aziz & Kaye Business Law has an established track record in competition and antitrust matters. Founding partner Luis Alberto Aziz, a seasoned practitioner with over 20 years' experience, heads a practice that has been involved in numerous significant merger notifications and investigations carried out by the COFECE; it also has a solid track record designing and implementing legal audits and compliance programs. The expertise of Ismael Henestrosa (promoted to the partnership in 2020) has allowed the practice to further bolster its capacity in the sector; he is particularly strong in the antitrust segment, primarily regarding investigations. Moreover, the practice was further strengthened with the arrival of senior associate Mauricio Marín -a former deputy director general of contentious affairs at COFECE- who specialises in antitrust litigation.

The trajectory we have built, together with the knowledge and prestige of our founders, Luis Alberto Aziz Checa, Allan Kaye Trueba, and our partner Ismael Henestrosa Pérez, represent a strategic formula, which is strengthened by the work and knowledge of our associates and trainees, who today are at the disposal of our clients.

More than 30 years of experience behind us.

Corporate law, mergers and acquisitions, antitrust, administrative law.

Our firm is well-known for its different, practical approach to our clients’ needs and projects.

The foundation of the success of Aziz & Kaye Business Law is the advice we offer to our clients, proposing efficient solutions based on solid legal knowledge and our combined experience and vision in the field of business. Our clients recognize us as consultants and advisors that bring added value to the growth of their business. Our corporate, competition and antitrust teams honor that approach and go beyond legal advice, offering advice on business strategies.

We advise some of the largest domestic and global companies on their most strategic and transformative projects in Mexico. Our corporate, competition and antitrust teams are highly specialized and very active in the market. In the competition and antitrust areas, we have been involved in various important mergers notifications and investigations carried out by the Federal Economic Competition Commission (COFECE). Our mergers and acquisitions team have successfully closed several high-value transactions of local and international relevance, and our corporate team provides advice as well as useful tools to our clients in their everyday affairs.

In addition, our deep knowledge of the law, and affinity and understanding of our clients’ businesses has allowed us to proactively and successfully advise them in their daily operations, as well as design and implement legal audits and compliance programs to detect, prevent and minimize legal risks in areas such as corporate, data protection and competition matters. We believe this extensive involvement differentiates us from most of our competitors.

The Mexican competition authority recognizes our high ethical and professional standards, which has allowed us to represent and advise companies in leniency programs in cartel investigations, and early closure programs in abuse of dominance and unlawful concentration investigations, both conducted by COFECE. Our corporate team’s thorough execution has been acknowledged by our clients, awarding some of our members with positions on their boards and continuous post-closing engagement.

Partners have been recognized by Chambers magazine, The Legal 500, LACCA, Best Lawyers, The Lawyer Network, the Expert Guides, Latin Lawyers and Lexology, among others.
