Q&A

My practice sits at the intersection of high-value commercial litigation and appellate work. I take cases from first instance through to the Supreme Court, which means every claim is built from day one with the appeal in mind. Much of my work involves complex financial products and mass claims, where I combine procedural strategy with economic analysis and, increasingly, with technology, including the use of artificial intelligence in litigation management.

Clients usually ask whether their case is worth pursuing and how long it will take. My answer is always a candid assessment of the merits, the realistic timeline (including possible appeals) and the costs, so they can make an informed decision. Many also ask about litigation funding, which can allow strong claims to go forward without the client bearing the full financial risk.

A multi-currency mortgage case against Bankinter, in which the Court of First Instance No. 25 bis of Valencia ruled that the bank had failed to provide sufficient pre-contractual information on the currency risk. Following the judgment and a supplementary order in July 2026, the bank paid our client €91,543.59 in September 2026. The case shows that, years after the first wave of litigation, well-founded multi-currency claims can still succeed, and it was featured in an interview in Economist & Jurist.

Appellate and Supreme Court work leaves little room for error: cassation appeals are subject to strict admissibility requirements, and a case can be lost on form before its merits are even considered. In financial litigation, the challenge is translating highly technical products into clear legal arguments that a court can apply.

I have been inspired by Napoleon Hill, Carnegie and Nick Bostrom, and by the great creators who anticipated the future. Today that inspiration takes the form of an AI-first vision of the legal profession: a new kind of hybrid lawyer who combines legal judgment with the integration of AI tools to multiply his capabilities many times over.
