    Our experience in Public Law and Regulation enables us to support domestic and foreign companies at every stage, from due diligence through project implementation and its full lifecycle, focusing on legal certainty and efficiency.

    Our team consists of lawyers specialized in Public Law and market regulation with extensive experience in privatization and concession projects, as well as markets regulated by the government, especially in telecommunications, media and audiovisual, civil aviation, airports, highways, mining, gaming & betting, sanitation, infrastructure, ports, defense, and public services in general.
