It was born after its founding partners realized the need and opportunity to start a unique and revolutionary project in the law firm market in Portugal. The Antas da Cunha & Associados project is based on a perspective of sustained growth tailored to the exact needs that we feel and that are conveyed to us by our clients.
One of the characteristics at the origin of the firm was the strong academic component of the team and its founders. The experience of university teaching is reflected in the knowledge of substantive law that enables the technical consolidation to solve problems in a practical and efficient manner.
At Antas da Cunha & Associados we are aware of the need and the desire for permanent innovation in order to better adapt to the demands of our clients and the dynamics of the market.
The team at Antas da Cunha & Associados has a diverse experience in the context of the Portuguese legal practice, allowing for a global vision of the market and anticipation of client needs.
The firm is marked by a strong and deep-rooted culture of work and solidarity, guided by a deep respect for the ethical principles of the profession, but always focused on the best solution for the client and on the provision of legal services of excellence.
We are governed by values such as independence, rigor, and exceeding expectations through results. We work alongside our clients, discussing and always seeking innovative solutions.
Ecija is considered by several international directories as the best law firm in Spain in the areas of TMT (Technology, Media & Telecom), and the merger operated in 2017 is a milestone and a bet by Antas da Cunha & Associados in areas in which Ecija is a leader and that are unavoidable and critical in the lives of economic agents.
