ECIJA is distinguished by its capabilities in cross-border matters, benefitting from the firm’s presence in multiple jurisdictions in Latin America and its recent alliance with Taylor Wessing LLP, which has strengthened its ability to advise key players in the digital economy. The team has an excellent record of advising prominent multinationals on M&A deals and the launch and reorganisation of their operations in the region, in addition to providing support with compliance issues and free trade zone matters. Practice head Guillermo Zúñiga, who is praised for his ‘in-depth knowledge of his field’, with complementary expertise in the real estate and renewable energy sectors, is a go-to adviser to foreign investors in Costa Rica. He is ably supported by energy sector specialist Mariela Hernández, Monserrat Soto Roig, who was promoted to partner in September 2024 and is skilled in the coordination of multi-jurisdictional projects, and senior associate Warren Corrales. Clients also benefit from the firm’s ECIJA Tech offering, which provides customised project management tools. The firm further strengthened its presence in Costa Rica in March 2025 through the incorporation of local boutique Acacia Legal, with experienced corporate practitioners Evelyn Galán and Elissa Stoffels joining as senior counsel.
