About us

Antas da Cunha Ecija & Associados is a project born from its founding partners’ realisation that there was a need and a great opportunity to start an unparalleled and revolutionary project in the Portuguese legal market. Antas da Cunha Ecija & Associados is built on a perspective of sustained growth tailored to address the needs felt by us and that our Clients bring to us. The solid academic background of our team and of two of our founding partners was the stepping-stone for this project. Over ten years of university lecturing experience provide in-depth knowledge of substantive law, which in turn results in the consolidation of all knowledge to solve problems in a practical and efficient manner.

We are, however, well aware of the constant need to innovate. Innovation is the driving force behind our daily work, enabling us to be better equipped to meet our clients’ requirements and stay in step with market dynamics. Made up of people with very different backgrounds – from sole practitioners to members of a top Portuguese law firm – our team has a very rich and diversified experience in Portuguese law, allowing for a global view of the market and of our clients’ needs. Our whole culture is client-oriented and built on legal services of excellence provided by a young and dynamic team that has worked together during the last ten years. A decade thinking of you!

Values such as independence, thoroughness, exceeding clients’ expectations, seeking innovative solutions, working side by side with our clients, guiding them in their search for the best solution, are values that have been acknowledged by our Clients and national and international opinion leaders alike, who have distinguished our team in their fields of practice.

ECIJA is considered to be one of the best law firms in the areas of TMT (Technology, Media & Telecom) by several international directories. Our 2017 merger with ECIJA represents a milestone in our history and a new commitment of Antas da Cunha & Associados to the areas where ECIJA is a leader and that are of the utmost importance in the day to day activities of business.
