We take pride in providing agile and practical advice to clients.

Our lawyers have been leading partners and associates in specialist practices of large national and international law firms.  Overall, we have practiced in Madrid, Barcelona, Washington D.C., London and Brussels.  We have advised some of the most representative and demanding national and international corporations in some of their most sensitive matters.

We are specialists covering four specific practice areas:

A leading practice with an extensive and widely recognized track record for competition and regulatory matters.

One of the strongest and most specialized practices within the venture capital and high growth companies landscape in Spain, acting constantly for companies and investors in early and later stage financing rounds through to successful exits by means of mergers and acquisitions.

We have first-class administrative and regulatory litigation skills both before lower courts and up to the Supreme Court and European courts; and we have also advised on selected civil litigation matters such as damages actions and complex commercial disputes.

Finally, we provide commercial and regulatory advice within the communications, media and technology sectors.

If you have a need and we feel we cannot service it, our commitment is to make available to you our extensive network of professional contacts on the ground and make sure we recommend the best suited individual to assist you, or team up with us, to tackle your particular need.  One of our strengths is our independence and absence of any commitment with any other individual or organisation: our only guiding principle is our clients’ best interest.

Our team has a remarkable international background, both in terms of legal training and business experience.  Our partners are dual qualified in Spain and England. Our lawyers are native speakers of four European languages and we have the skills to carry out our work in English, Dutch, French, German, Italian, and Spanish.
