O’Farrell has a longstanding disputes practice with notable depth in civil and commercial litigation, class actions, regulatory conflicts, and arbitration. The team is particularly active for clients in the automotive, transport, pharma, and industrial sectors. The practice is driven by Francisco Astolfi, who is at the forefront of heavyweight civil and commercial disputes for multinational companies and clients in regulated sectors. He is supported by a strong team that includes Federico Daurat, who specialises in commercial judicial and arbitral proceedings, particularly in contractual claims; the deeply experienced Juan Matienzo, who -as he celebrates 30 years at the firm- is regularly involved in significant commercial and regulatory disputes; and senior counsel María Fortuna, who works at the intersection of constitutional, public, environmental and energy sector conflicts. Former associate María Fernanda Derudder left the firm for the Buenos Aires judiciary in February 2026.
