Lima, 1 October 2026. Rubio Leguía Normand announced the addition of Renato Vásquez Armas as a partner and Ángel Rodríguez as a consultant in its Dispute Prevention and Resolution Practice. With their arrival, the firm integrates the practice of Armas Abogados, a boutique specialising in strategic litigation, risk prevention and management, regulatory defence and crisis management. These additions strengthen an approach to disputes that begins with understanding their impact beyond court proceedings. The team combines a litigator’s experience, the perspective of someone who has managed risks and made decisions within a business, and legal research capabilities that are particularly relevant to highly complex disputes. Rubio Leguía Normand partners Bruno Marchese, head of the Dispute Prevention and Resolution Practice, and Giancarlo Celis, who together lead the practice, commented: “Our work does not begin when a dispute reaches the courts. We seek to understand what is at stake for the client, anticipate risks and determine the most appropriate strategy before, during and after a dispute. Renato and Ángel strengthen this approach: they bring business experience, strategic insight and in-depth legal knowledge that will be particularly valuable in the most complex matters. They also expand our litigation capabilities in sophisticated and complex cases involving family law, family assets and the best interests of children.” Renato Vásquez Armas advises and represents domestic and international companies in constitutional, administrative, civil, family and corporate disputes, as well as in dispute prevention, compliance and the management of legal and reputational crises. After working at Benites, Forno & Ugaz, he led the legal and corporate affairs functions at AB InBev Peru and served as head of legal at Grupo AJE. These roles gave him first-hand insight into how disputes affect business operations, reputation and decision-making. In 2017, he founded Armas Abogados, where he developed a practice focused on strategic litigation, risk management and regulatory defence. Renato said: “As head of legal, I learned that a dispute is, above all, a business decision. My role is to help the client determine when to prevent a dispute, when to negotiate and when to litigate, and to implement that decision with full procedural rigour. At Rubio Leguía Normand, we have found the capabilities and reach to apply this approach to disputes of greater scale and complexity.” Ángel Rodríguez joins as a consultant, bringing more than 25 years dedicated to the study, systematic analysis and publication of Peruvian law. His experience in legal research and legal philosophy will reinforce the practice’s strategy in constitutional litigation, civil litigation involving property and non-property rights, and parliamentary law, including representation before investigative committees of the Peruvian Congress. Ángel commented: “In a complex dispute, legal research must be part of the strategy from day one. Understanding the opposing party’s arguments, the court’s previous approach and the legal grounds that best support our position enables us to build a much stronger defence. That will be my contribution to the team.” With these additions, Rubio Leguía Normand builds on the sustained growth of its Dispute Prevention and Resolution Practice over the past four years, expanding its ability to support clients throughout the full lifecycle of a dispute: anticipating risks, preventing conflicts, defining strategies, negotiating and, where necessary, litigating, while combining business experience, litigation strategy and in-depth legal analysis.

Rubio Leguía Normand has strengthened its Banking & Finance and Corporate/M&A practices with the appointment of Juan José Hopkins as Partner. Juan José brings broad experience in financial transactions, M&A, venture capital, fintech and trust structures. He has advised companies, financial institutions and emerging businesses on financings, corporate transactions, investment rounds, fiduciary arrangements and digital business needs. His arrival strengthens Rubio’s ability to support clients across traditional finance, corporate transactions and fast-growing areas such as fintech, venture capital and startup financing.
