Stephen Sampson, EMEA head of the Litigation Practice Group, said: “Our firm has a deep and broad bench of disputes lawyers in four continents across the globe. Lorena is a talented lawyer with experience in many high-profile cases, and we are very pleased that she has chosen us as the firm to join on leaving the State Attorney's Office. She joins a strong practice in Madrid headed by Javier Izquierdo, and I know will stand ready to serve clients, on both domestic and international work including through our deep connections in Latin America.”
Teresa Zueco, managing partner of the Madrid office, added: “We’re delighted to have Lorena join us. She has an excellent reputation and many years’ experience at the top of her field. As our business has grown, with lawyer numbers increasing by a quarter in the past three years, we have been focused on making Madrid a full-service office with both specialist expertise that clients need and real strength in depth in core areas. Litigation has been a strategic focus and under the leadership of Javier Izquierdo we have built a team in Spain to be rightly proud of.”
Lorena Fatás is a highly experienced arbitration and litigation lawyer. Before becoming a State Attorney in the Special Department for Economy, Energy and Environmental Law within the State Attorney Office, she served for more than five years in the Spanish government’s International Arbitration Department, where she became the Deputy Head in 2021. During this time, she advised and represented the Kingdom of Spain in complex investor-state disputes, particularly under the Energy Charter Treaty (ECT) and bilateral investment treaties (BITs).
Lorena’s expertise includes investment and commercial disputes, representation of sovereign states, and advisory work in sectors such as banking, energy, infrastructure, and state-owned enterprises.
