CGM is an independent law firm located in São Paulo, Brazil, founded in September 2014 by an experienced group of partners who have worked together for more than two decades and other partners who joined the team along the years coming from reputable law firms.

With strong client and market recognition in their respective areas and in important international publications and rankings, CGM’s focus is to solve the issues of the clients and in a timely and business-oriented manner, with technical expertise and creativity.

The firm has a team of professionals graduated from leading law schools in Brazil. Many of them have obtained master degrees and other qualifications abroad and have worked out of Brazil. The result is, above all, a close, integrated and multilingual staff with shared perceptions, principles and objectives, prepared to offer their professional experience to our daily activities. Our tightknit network of partnerships allow us to provide services in Brazil and coordinate multijurisdictional projects in Latin America.

CGM’s team works at a very fast pace and has in-depth knowledge of the law and of the business of our clients. We represent our clients very assertively, with a high orientation to detail and an appetite for the development of creative approaches for the protection of our clients’ interests. In addition, our long-term experience working with international clients results in the ability to explain the Brazilian legal system to foreigners in a very practical way and be sensible to cultural aspects in the development of business with them.
