Marval O’Farrell Mairal’s blend of advisory and contentious expertise positions it as a formidable force in Argentina’s competition law landscape. The practice is co-led by María Lorena Schiariti, who advises corporates on integrity and compliance programmes, dealings with public officials, and enforcement actions, alongside Andrés O’Farrell, who stands out for his work in internal audits and white-collar crime issues, frequently involving breaches of fiduciary duties. Miguel Del Pino is regularly entrusted with sensitive antitrust investigations and regulatory proceedings, while younger partner Santiago del Rio advises clients on merger-control filings and abuse of dominance matters. The team also benefits from the involvement of senior associates Gabriela Ariel Irizar, who is well-versed in anticompetitive conduct mandates and merger control proceedings; and Brenda Madonna Ackermann who assists with regulatory issues, with a particular focus on transactional antitrust work.
