Law Firm Incorporation

Year of its foundation – the firm was established as Remelgado, Sousa, Nogueira, with Fátima Remelgado, Antónia Leite de Sousa and José A. Nogueira as its founding partners. Since its Foundation the firm aims to be focus on companies and entrepreneurs.

New designation

In February 2007, Antónia Leite de Sousa left the firm and a new designation was adopted: “RSN – Remelgado, Silva Nogueira & Associados – Sociedade de Advogados R.L”. These have been years of a strong growth, both in terms of turnover, scale and operations’ complexity.

New premisses

Opening of the new office on Avenida da Boavista (Oceanus Building). The firm entered a new phase in which personalised service forms the cornerstone of its work, with the lawyer-client relationship playing an increasingly central role. The specialisation and the increasing standards required of the professionals that integrate the firm, become key pillars of this project.

Vision for the Future

The firm embraces the present with one foot firmly planted in modernity (offering its clients transparency, technological tools and productivity solutions) and the other in a rigorous and wholly independent approach to the legal profession, grounded in a deep strategic alignment with clients and the essential pillars of the profession, whilst maintaining its autonomy in the face of multidisciplinary models.
