Eldy Roché helps clients resolve high-stakes international arbitration disputes spanning multiple borders, legal systems, and languages. Drawing on her dual civil- and common-law training, she advises on cross-border disputes involving energy, mining, and infrastructure claims. She represents clients in Investor-State disputes (ICSID, UNCITRAL) and commercial arbitrations (ICC, ICDR, UNCITRAL) bridging legal traditions to deliver strategic, results-oriented advocacy at every stage of the arbitral process.

Eldy’s practice centers on helping clients protect their investments and resolve complex disputes in heavily regulated industries. She regularly represents multinational corporations, and private investors in arbitration proceedings arising from energy concessions, mining operations, and large-scale infrastructure projects. Her work often involves multibillion-dollar claims where the legal, technical, and political dimensions intersect.

Clients rely on Eldy for her ability to operate seamlessly across legal traditions. Having grown up in Honduras, where she earned her Abogado degree, and later obtaining a Juris Doctor and an LLM in Comparative Law in the United States, she brings firsthand cultural understanding of the region and a practical command of how different legal frameworks shape strategy—particularly in disputes governed by the laws of jurisdictions across Latin America and other civil law jurisdictions in Europe and Asia. She conducts arbitrations in both English and Spanish, which allows her to work directly with witnesses, counsel, and tribunals without the friction of translation.

Eldy is especially valued for her collaborative approach to technically demanding cases. She works closely with industry consultants on issues such as reservoir engineering, the decommissioning of oil and gas installations, environmental remediation, and telecommunications infrastructure—translating complex technical evidence into clear, persuasive legal arguments.

In addition to her arbitration practice, Eldy serves as an Adjunct Professor at the University of Miami School of Law, where she teaches in the International Arbitration Program. Her academic engagement keeps her at the forefront of developments in the field and reflects her commitment to advancing the practice of international dispute resolution.
