Competition

Una superficie reflejante juega con las sombras de la luz que entra por una ventana.

We stay one step ahead of the competitive trends that affect your business.

In an increasingly complex and dynamic regulatory environment, ECIJA has established itself as a leading firm in competition and antitrust law in Ibero-America. Our approach combines legal excellence, economic analysis and technological expertise, offering innovative solutions that enable our clients to stay ahead of regulatory changes and minimise financial and reputational risks.

Competition investigations, mergers and antitrust litigation are now more sophisticated, with authorities using digital tools and artificial intelligence to detect restrictive behaviour more quickly.

In this context, it is essential to have a team with an international reach and in-depth local knowledge, capable of devising robust defences and preventative strategies across multiple jurisdictions.


Our multidisciplinary team, comprising specialists in competition law, the digital economy and technology regulation, advises global companies across the full spectrum of antitrust matters: merger control, investigations into restrictive practices, compliance programmes and complex litigation.


Our mission is clear: to protect our clients’ market freedom and give them the confidence they need to compete in a global landscape characterised by scrutiny and innovation.

"The team has incredible expertise and knowledge in the field of competition law. They take a very practical approach and are a pleasure to work with."
