About

Provided by AUREN

Auren’s Litigation and Dispute Resolution practice is one of the firm’s most consolidated and dynamic areas, with a strong presence across the Spanish jurisdiction and a long-standing track record advising both national and international clients. The department is particularly recognised for its ability to manage high-volume litigation portfolios with consistency, technical rigor and a strategic approach adapted to each sector.

The team regularly advises leading players in the financial sector—including CaixaBank, Banco Santander, Banco Cooperativo Español, Cajaviva, Globalcaja, Caja Rural Salamanca, Caja Rural Granada and Unicaja Group (Unicorp Vida)—handling complex litigation related to financial instruments (such as swaps), collective actions, and mass claims involving mortgage and consumer contracts. Many of these cases are pending before the Supreme Court or are expected to escalate to the European courts due to their legal and social impact.
