SRS Advogados is a full-service, multi-practice law firm advising clients on all aspects of national and international law.

Our lawyers are focused on their clients' business and have acquired knowledge and experience by advising large national and international corporate groups and financial institutions over the last 30 years.

Through the creation of SRS Global (Angola, Brazil, Macau, Malta, Mozambique, Portugal and Singapore), as well the creation of a strong network of international relationships with third parties, we aim to extend our experience, expertise and services globally so as to ensure that we can respond efficiently to complex issues with global implications.  


Established in 1992, SRS was the first Portuguese law firm to have a formal international association, forming part of Grupo Legal Português, a group comprised of Simmons & Simmons, J&A Garrigues, Pinheiro Neto.

All its members belonged to a broader network, Club de Abogados, which comprised members from all principal European and Latin American countries.

Founded with a strong focus on internationalisation, specialisation and institutionalisation, SRS Advogados was one of the first firms to offer a career plan plus a strategic framework, and lead its peers in terms of both internal and external dynamic.


In addition to an existing civil and commercial law practice, in 1993 a new finance practice was developed under the leadership of Pedro Rebelo de Sousa. Pedro's career had been intrinsically linked with the world of finance having worked for Citibank in Brazil (from 1976 to 1985) and then New York (from 1985 to 1989). From 1989 to 1991 Pedro was chairman of the Portuguese state owned bank, Banco Fonsecas & Burnay, which was under his leadership re-structured and privatised in 1991. This new department at SRS Advogados was focused on banking and capital markets, as well as M&A, corporate finance and project finance.

In 1994, the firm had moved from a small office in Rua Fialho de Almeida to two floors in a modern building on Rua Castilho.



From 1995 to 2000, the firm co-ordinated and advised the arrangers/underwriters on the five phases of the privatisation of Portugal Telecom (at the time the only telecommunications company in Portugal), in what was a groundbreaking first IPO of shares in a Portuguese company.

From 1993 to 1996, the firm was heavily involved in advising on World Bank and EU projects aimed at standardising international legislation, and in this context drafted legislation on banking, investment, and tax for countries such as Belarus, Russia and the Ukraine. At this time, the firm was also increasingly involved in international and domestic capital markets transactions and acted on (and structured) the first ever securitization in Portugal in 1997.

In 1996, J&A Garrigues in Spain merged with the auditing firm Arthur Andersen. As a result of this merger, the Spanish firm left the joint venture. Shortly thereafter, and due to conflict issues, Pinheiro Neto also left the joint venture. Further to the departure of Pinheiro Neto, SRS Advogados established a joint venture with leading Brazilian law firm Veirano Advogados, with offices in São Paulo, Rio de Janeiro, Brasília and Porto Alegre.




In 1997, the firm adopted a policy of social responsibility and took up pro bono work.

The firm opened an office in Madeira in 1998 and its Oporto office in 1999.

 In 1999, the firm occupied seven floors of the building in Rua Castilho, occupied by over one hundred employees.



Between 1995 and 2000, the firm was a pioneer in developing products for the financial sector (derivatives, securitisations, structured products, etc.) and took part in numerous privatisation, project finance and corporate financetransactions in Portugal, Angola, Mozambique and Macau.

In addition to its leading position in the financial sector, the firm also developed a reputation for excellence in the telecommunications sector, and in particular was involved with the launch of four new telecommunications operators in Portugal.


In 2001, as a part of its increasing alignment with Simmons & Simmons, the firm merged with Simmons & Simmons and changed its name to Simmons & Simmons Rebelo de Sousa.


In the 2000's, the integration with Simmons & Simmons took shape. A number of Partners such as Pedro Rebelo de Sousa, William Smithson, Octávio Castelo Paulo, César Sá Esteves, Alexandra Valente and José Luís Moreira da Silva became Partners of Simmons & Simmons. Additionally, Pedro Rebelo de Sousa was a member of the Simmons & Simmons Management Board for two terms (eight years), and Octávio Castelo Paulo was appointed head of the Simmons & Simmons international TMT sector group, which he successfully lead for 6 years.
In 2005, SRS Advogados became the first Portuguese law firm to have its accounts audited by an international auditor.
Also in 2005, the firm moved its head office and took over an iconic 1970s building just off Rua Castilho, the symbol of an era and the former headquarters of Readers' Digest.


In 2009, with a view to creating greater strategic freedom, SRS Advogados went independent and ceased to be a part of Simmons & Simmons, while at the same time remaining good friends with Simmons & Simmons.

As a result of its greater strategic freedom, SRS developed its first international offices in Africa. In 2009 an agreement was concluded with an Angolan law firm in Luanda and in 2010 with a Mozambican firm with offices in Maputo.

The firm believes strongly in developing new practice areas (e.g. employment, immigration, European and competition) and has an innovative matrix focusing on specific sectors, such as Energy, Infrastructure and Life Sciences, in addition to its existing TMT and Financial Institutions sector focus.


In 2010, a merger was concluded with boutique litigation firm Soares Machado & Associados, headed by José Carlos Soares Machado (former chair of the Lisbon District Council of the Portuguese Bar Association), which provided considerable impetus to the Litigation and Arbitration practice at SRS Advogados.


Twenty years on from its inception, the vitality of the SRS Advogados project was indisputable. It had 19 partners (over 30% of whom were women) and a personal development plan for employees. Innovation has been, and always will be, present and the firm was a pioneer in Portugal in the context of administrative support structures for the legal profession.



In 2014, SRS Advogados launched SRS Global, with a network of international offices in Angola, Brazil, Macau and Mozambique.


SRS is clearly and definitively classified by its clients, as well as international directories, as one of "go to" Portuguese law firms in all practice areas. Recognition of its worth has been reflected in countless distinctions, which are not only a source of pride but also of motivation to maintain the high standard of service provided.

The firm was voted the "Best Company to Work for" in Portugal for several years running and in 2016 was nominated "Healthiest Company" by IMS Health, placing it amongst the top three highest ranking companies in Portugal. 

SRS Global was further enhanced in 2016 with the establishment of a Malta office.  


In 2017 SRS Advogados opened an office in Singapore - yet another first for a Portuguese law firm - and celebrated 25 years of leadership in law in Portugal.

In the same year, the firm was shortlisted in The Lawyer European Awards for "Law Firm of the Year: Iberia", "Global Strategic Initiative of the Year", and "European Energy and Infrastructure Deal of the Year" and was shortlisted in the Chambers European Awards for "Portugal Law Firm of the Year".

SRS Advogados also won European Competition/Antitrust deal of the year at The Lawyer European Awards.


In 2010, SRS Advogados merged by way of incorporation of AAA Advogados into SRS Advogados, with recognized notoriety in the Portuguese business and financial market.

This integration results from the SRS strengthening strategy defined at the end of 2019.
