Our practitioners possess specialized expertise in orchestrating these proceedings, ensuring that our clients' legal interests remain robustly protected throughout every stage of the negotiation process.

Our practice encompasses complex contractual disputes, investment conflicts, shareholder litigation, and controversies arising from operational agreements within heavily regulated sectors. We possess distinguished expertise in arbitrations concerning Mining, Oil & Gas, and Port Logistics, where substantial amounts in controversy and technical intricacies necessitate counsel with profound legal and sector-specific acumen. By serving as both party representatives and appointed arbitrators, our firm offers a comprehensive and strategic perspective throughout the entire arbitral process.
Our permanent legal advisory service provides corporations with continuous, sophisticated support for both daily operations and high-stakes strategic decision-making. We operate as an elite external legal department, delivering comprehensive coverage across all practice areas impacting the corporate sphere: commercial contracts, regulatory compliance, labor relations, corporate governance, and tax law. We assist our clients in structuring complex transactions, implementing proactive risk management protocols, and ensuring strict adherence to industry-specific regulatory frameworks, with a core focus on the Mining, Oil & Gas, and Port Logistics sectors. Our mission is preventively oriented, identifying and mitigating legal exposure before it escalates into formal litigation. Providing meticulous counsel, we ensure your business remains legally resilient in a dynamic market.
We regularly assist international corporations entering the Argentine market, providing full legal support from initial investment structuring and regulatory approvals through to the ongoing management of their local operations.
