Built for what’s next.

The law firm of the future, today.

Antas da Cunha Ecija is a full-service law firm prepared to respond to the complexity of a market in constant transformation.

As the first Full AI Firm in Portugal, we integrate Artificial Intelligence across all areas of our activity in a transversal, strategic and sustained way - a capability that is now embedded in how we analyse, decide and develop legal solutions for Clients and Partners.

With more than 200 professionals across Lisbon, Oporto and Braga, we bring together multidisciplinary teams that work closely and collaboratively, combining technical expertise, sector-specific knowledge and an approach tailored to the specific reality of each organisation and challenge.

The firm’s international dimension further strengthens this capability. As members of ECIJA, the largest Ibero-American law firm, we are part of a platform with 37 offices, presence across 18 jurisdictions and more than 1,200 professionals.

We continue to grow with the same ambition with which we started: to build a firm prepared to lead the future of law.
