The office adopted a corporate structure on May 29, 1992, having as its 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.
