What Martinez de Hoz & Rueda does

Martinez de Hoz & Rueda (MHR) is a full-service Argentine law firm founded in 2018, headquartered in Buenos Aires at Torre Fortabat, Bouchard 680, Piso 19, with additional offices in Neuquen (Patagonia) and Montevideo (Uruguay). The firm is led by founding partners José Martínez de Hoz and Pablo Rueda and operates as a private partnership with 16 partners, 3 counsel, and approximately 43 associates — 62+ legal professionals in total. MHR positions itself as the #1 energy practice in Argentina, anchored by on-the-ground presence in the Vaca Muerta hydrocarbon region, and complements this with top-tier corporate/M&A, litigation, tax, banking and capital markets, compliance, mining, infrastructure, public law, arbitration, and maritime law capabilities.

The firm's service offering is delivered through partner-led, enterprise-focused engagement with large corporates, multinationals, energy and natural resources companies (oil and gas, mining, renewables), and financial institutions requiring sophisticated legal representation in Argentina and the broader LATAM region. The firm is a bilingual (English/Spanish) practice with a dedicated LATAM regional portal (mhrlatam.com) and operates across three jurisdictions. Client-facing deliverables include regularly published newsletters covering energy, corporate law, tax, compliance, and banking/finance, alongside thought leadership contributions to Lexology Getting The Deal Through, Latin Lawyer, and arbitration reviews.

MHR's revenue model is professional services-based, generating income through fees on legal mandates across multiple practice areas, with pricing not publicly disclosed and engagements typically structured on hourly or quote-based terms. The firm has accumulated recognition across Chambers Global 2026, Legal 500 Latin America 2025 (Top Tier), IFLR1000 (Top Tier Firm), Leaders League, GTDT, World Tax, ITR, Latin Lawyer, Who's Who Legal, LACCA, and Global 100. Recent strategic activity includes a February 2026 major expansion announcement, a 2023 corporate governance restructuring, and ongoing 2026 associate and paralegal hiring, signaling an offensive scaling posture.
