Squire Patton Boggs strengthens its Litigation practice in Spain with the appointment of former State Attorney Lorena Fatás

Squire Patton Boggs has announced the appointment of Lorena Fatás as partner in its Litigation Practice Group in Madrid. Formerly a State Attorney in the Special Department for Economy, Energy and Environmental Law within Spain’s State Attorney Office, Fatás is widely recognised for her experience handling complex litigation, arbitration, and regulatory disputes.

Stephen Sampson, EMEA head of the Litigation Practice Group at Squire Patton Boggs, commented: “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.”

Before joining Squire Patton Boggs, Lorena Fatás spent more than five years in the Spanish government’s International Arbitration Department, where she became Deputy Head in 2021. During that period, 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).

Her practice focuses on investment and commercial disputes, sovereign state representation, and advisory work in sectors including banking, energy, infrastructure, and state-owned enterprises. She also has extensive experience in the recognition and enforcement of arbitral awards across multiple jurisdictions, as well as in proceedings before institutions such as ICSID and SCC. Her work in international arbitration has additionally been recognised by UNCITRAL, where she participated in one of its working groups on ISDS reform.

Commenting on her appointment, Lorena Fatás said: “I’m very pleased to be joining Squire Patton Boggs. In dispute resolution work it operates at the highest level with impressive clients around the world. The firm’s presence in Spain is also a great success story and I look forward to working with the talented team there.”
