Who We Are

Founded in 1992 by José María Baño León, tenured professor at the Universidad Complutense of Madrid

We are a law firm specialising in administrative law and its related fields, including urban planning, environmental law, regulatory law, and competition law.

With over 30 years of experience, we are recognised for providing independent, rigorous, and high-quality legal advice.

Our practice is guided by a strong academic commitment that continues to shape our approach. From our senior partners to our newest lawyers, we blend the study of law with its application, regularly engaging with the University and its postgraduate lectures, seminars, and other forums to share and advance expertise in administrative law.

Our work is endorsed by prestigious legal rankings and, above all, by the trust of our clients, inspiring us to improve and continue learning every day.
