The Firm
Knowledge, Technology and Individualized Service
Bruno Salles Ribeiro, Leonardo Palazzi and Marco Antonio Chies Martins have almost 20 years' experience in criminal and corporate law, having worked in specialised and full-service law firms, where they gained experience in the most varied branches of criminal law, serving individuals and companies with availability, proximity and discretion.
In response to demand from our clients, the firm has also started to offer legal services in civil litigation, focusing on the areas of Obligations and Contracts, Banking Law and Civil Liability, Consumer Law and Family Law, Administrative Improbity and the Anti-Corruption Law. New demands and new challenges, from virtual fraud, breach of data secrecy, civil liability related to environmental damage, fake news, among other issues that are in evidence, have become the object of the firm's work.
We understand that there are no criminal cases that can be considered trivial. Whether it is due to the need for defense or having been a victim of a crime, those seeking assistance in criminal matters face a significant challenge. That is why we are here: to ensure the best possible resolution for the case, with the lowest possible cost for the client.

Litigation scope
In the business sector, our work always seeks to outperform the individual case in which it operates so that it can understand mechanisms for improvement that avoid or mitigate the incidence of criminal law on the clients’ activities.
In the advisory and litigation scope, our specialized services cover all and every matter that falls within the legal-criminal scope, developed throughout the national territory and in various cases with transnational reflexes.
Our team has extensive experience both in the scope of classical criminal law - those crimes provided for in the Criminal Code which aim to protect life, heritage, intangible property, organization of work, religious and dead feelings, sexual dignity, family, physical safety, public peace, public faith and public administration – and in the context of economic criminal law – criminal offenses provided for in autonomous laws and usually aim at guaranteeing the protection of specific subjects, such as the environment, the financial system, and the tax system.
