TELLES’s Growth

Due to TELLES's growth in terms of practices covered and to the integration of a substancial number of new lawyers and support staff members, TELLES has, during 2018, moved to new offices both in Lisbon and in Porto, oriented to increase the comfort of our team and of our clients as well as to promote a greater efficiency of our services.


TELLES in Lisbon

In January 2008, TELLES open its office in Lisbon, consolidating its nationwide presence.


Change of facilities in Porto

In 2002, we moved from our former facilities at Rua de Sá da Bandeira to Rua da Restauração, gaining state-of-the-art facilities in one of the most emblematic parts of the city of Porto.


Telles de Abreu, Delgado, Lucena e Associados

The office adopted a corporate structure on May 29, 1992, having as main founding partners, Luis Telles de Abreu, Rui Delgado and Carlos Lucena.



TELLES has its routes in an office that was founded in 1936 by Dr. Artur Santos Silva and has, since then, established itself as one of the most prestigious corporate legal firms in Portugal and a reference for corporate clients.

"Our lawyers believe that their role in the community includes involvement in civic responsibility initiatives, namely by ensuring access to the law through pro bono work."
