Aziz & Kaye Business Law

Competition and antitrust Tier 3

Founding partner Luis Aziz, a seasoned practitioner with over 20 years' experience, heads the practice at Aziz & Kaye Abogados, which is held in high regard by many clients for its offering and services in this sector. Indeed, it has a strong track record, with past matters including involvement in major cases such as advising Monsanto on its merger with Bayer, Grupo Financiero on its merger with Banorte, and Bardahl on its acquisition by Repsol Downstream. Former senior associate Ismael Henestrosa's election to the partnership in January 2020 will allow the firm to further grow its capacity in the sector; he is particularly strong in the antitrust segment, especially on investigations, and is praised for his ‘focus on business and excellent customer service’. 

Practice head(s):


HIgh ethical standards; about 20 years’ experience in the field; and a top three team. Also, full time availability, and the immediate identification of issues and solutions. I note Luis Aziz and Ismael Henestrosa.

Experience and focus on business. Despite handling one of the most complex and strict matters (competition and antitrust), the firm always maintains a business focus. I have worked with other renowned firms on these types of matters and Aziz & Kaye is the best firm in Mexico for these types of matters.

A business focus and excellent customer service: Luiz Aziz and Ismael Henestrosa.
