We are present wherever our clients need us: with our own offices in Portugal (Lisbon, Porto and Braga), Spain (Madrid, Barcelona and Valencia), the USA (Miami), Chile (Santiago), in the Caribbean, in Central America (Costa Rica, Dominican Republic, Panama, Guatemala, El Salvador, Honduras and Nicaragua) and in South America (Brazil, Ecuador and Argentina).
To go even further together, we created strategic alliances with renowned law firms in other countries around the world, allowing us to expand our global reach and offer integrated support in multiple jurisdictions. This ensures that we can recommend high quality services, both at home and abroad - always at the level of excellence that our clients deserve, expect and trust us to deliver, thus facilitating international projects with confidence and efficiency.
We keep our contact with the world alive through international events and associations, such as the International Bar Association, of which we are proud members. Since May 2017, we are the exclusive representative for Portugal in the Interact Law network (and the same is true for Spain), a network that covers all types of legal needs, from private clients to large corporations. It is our way of embracing internationalisation and growing alongside those who trust us.
