Siqueira Castro Advogados

During our 70 years of history, we have played a main role in the evolution of the legal sector in Brazil. Today, we are one of the largest firms in Latin America, with a team of more than 2,500 members in 18 Brazilian cities. Always focused on innovation, we have expanded our services to all areas of business law and evolved to offer our clients more than legal work. We render strategic consultation with legal intelligence.

This intelligence is our greatest asset. Providing the full range of legal services is just the start for us. It is through deep and multidisciplinary knowledge – inside and outside the legal universe – that we are able to aggregate expertise to all our business solutions. We are more than full service. We are a full solution firm. We are more than lawyers. We are business advisers with legal training.

From the solution of highly complex problems to managing routine daily challenges, we advise our clients regarding the strategic conduction of business, the maximisation of opportunities and the anticipation/mitigation of risks. All this is achieved through continuous investment in technology, people and processes. 

Our structure is solid. We are present in all regions of Brazil. We believe that the diversity of Brazil is its greatest strength. Therefore, we are present wherever business is done, wealth is generated and our clients need our assistance. For every mission. For every project.

International alliances and partnerships give us insight into global trends and allow us to be part of the growth and affirmation of our country and our companies in the scenario of a highly globalised economy. It also makes our firm a safe and reliable access door for foreign companies that intend to invest in Brazil.

A strong culture of collaboration and partnership guarantees the integration of our different offices and generates efficiency, proximity and flexibility to the relationships with our clients.

The impact of SiqueiraCastro in the legal and business worlds, besides being known by clients and by the market in general, is regularly recognised by specialist publications, in Brazil and abroad. Year after year, we are repeatedly awarded in every different areas of business law.

The sum of all these different aspects define SiqueiraCastro: global scope with local flavour, always offering outstanding business consulting with legal intelligence. Throughout Brazil and abroad.

Social responsibility and pro bono

We are specially focused in initiatives that bring a positive impact on society. We support social assistance actions to improve the quality of life of needy and disabled people. We also provide pro bono legal services through long-term working arrangements with charitable and philanthropic institutions in many Brazilian states.

We have a Pro Bono Committee, organically implemented since the 1990s to support our efforts throughout Brazil. We now concentrate our social responsibility and pro bono activities through the Maria Clara Institute, which channels all our initiatives in the country with funds from our firm. At the present moment, our pro bono programme assists, on a permanent basis, 80 charitable institutions throughout Brazil. 

In recognition of our social work and pro bono activities, we received from the important British publication Latin Lawyer the title of “Best Pro Bono Firm in Latin America in 2007” and “Pro Bono Leading Light” in 2012, 2013, 2014, 2015, 2016, 2017 and 2018.
