Marval O’Farrell Mairal

Marval O’Farrell Mairal is a go-to firm for support on complex, sensitive disputes and is frequently sought out by local and international clients involved in high-stakes litigation and arbitration. The team litigates before all levels of the courts in Argentina and is also well-versed in ad hoc and institutional arbitrations in commercial, investor-state and bilateral treaty matters. Constitutional and administrative matters are also covered, as is bankruptcy litigation. A team of experienced partners is led by the exceptional Ricardo Ostrower who is frequently involved in complex, politically sensitive litigation. In addition, the practice draws on the specialist expertise of a deep bench of senior talent that includes Julio César Rivera (h) (commercial litigation, international and domestic commercial arbitration, insolvency and constitutional law), Santiago Soria (energy and natural resources disputes), Rodrigo García (family law and inheritance disputes), Elias Bestani (insurance, reinsurance, maritime and aviation disputes), and Facundo Viel Temperley (consumer and product liability disputes). The team also includes a cohort of younger partners, including the arbitration and litigation-focused Fernando Alemany and Martín Vainstein, another key name for energy sector litigation and arbitration who rejoined the firm from Cleary Gottlieb Steen & Hamilton in New York. Honorary partner Julio César Rivera, a former associate judge of the Argentine Supreme Court, provides additional support and vast litigation and arbitration experience spanning more than four decades.
