AC & Associados

We are your business partners, with effective and complete solutions to defend your interests.

Our Origin


The project began in Portugal, extending across borders, through a succession of events and interesting coincidences, which brought together the current members of our team.


This union boosted spontaneous synergies that were consolidated and it quickly became clear the added value that a heterogeneous and international team could leverage with customers who currently represent a challenging and increasingly diversified business reality.


From the beginning we believed that we could make a difference if we accepted the mission of creating the current office.


In 2013, for strategic reasons, we decided to create AC & Associados, intending to assert ourselves as a unified law firm, with different skills, with the assumed technical competence of its lawyers and employees, always basing its conduct on scrupulous respect for ethical and deontological rules.


AC & Associados sustains their approach through preventive law and a natural interaction between Lawyers and Clients, always maintaining a close relationship with our Clients.


Our Ambition


Advising locally, growing internationally with each client.


Despite being recent, our office currently advises operations and important economic groups in several jurisdictions, with our team having a proven know-how and practical knowledge of each local reality in which it operates.


AC & Associados already has representation, through local partners, in the Azores and Madeira Archipelagos, Angola and Brazil, thus expanding its capacity to respond to its clients.



The origin of the office is intimately linked to the people who are part of it.

The reason that led a group of people, with know-how and proven experience in different areas of work and jurisdictions, coming from offices so diverse in their organizational structure, with deeply enriching and distinct experiences, to leave their comfort zone and undertake such an ambitious and innovative project is the firm conviction that, through the interaction and cooperation of our team, we could offer an innovative and high quality service, catered to the needs of each particular client.
