Launched in 2010, Wiener Soto Caparrós (WSC) set out to change the delivery of legal knowledge and services in Argentina. We brought together a highly-qualified team of almost 20 professionals admitted to practice in Argentina, the USA and Brazil to provide legal and support services to businesses, investors and individuals navigating a challenging legal environment.
We define WSC as a ‘problem-solver’ and more than a conventional law firm. One major distinguishing factor is our ability to solve multijurisdictional problems (i.e. problems involving persons from different countries and legal systems). Having foreign attorneys on our team gives us a distinctive capability to interpret and explain these problems and to create effective solutions. In addition to helping clients understand the legal and business environment in Argentina and Latin America, we facilitate their understanding of the region’s idiosyncrasy.
Through a network of associated law firms, WSC advises clients in Argentina, Brazil, Colombia, Chile and other Latin American countries. Attorneys of the firm specialise in corporate law, banking and finance law, M&A, antitrust law, litigation and dispute resolution, taxation, employment law and insolvency law. Our particular expertise is providing advice on cross-border investments and activity between common law and civil law jurisdictions.

We also offer extensive experience in privatisation and infrastructure projects involving large-scale civil works and public services, including toll roads, water & sewerage, natural gas distribution and transportation; electrical distribution, transportation and power generation.

WSC attorneys actively participate in several professional associations and academic endeavours. This involvement is driven by the firm’s desire to remain contemporary and prepared to confront the challenges that arise in the fast-changing legal-business environment. WSC maintains a pro bono commitment to bring legal services and sponsorship to sectors and persons unable to access justice.

Our approach

WSC is experienced, focused and dedicated to:

  • Providing high-quality legal and support services to help clients overcome obstacles and reach their goals.
  • Fostering long-term relationships with clients, human resources and vendors. We look to gain our stakeholders’ trust by understanding their needs and providing them sustained value.
  • Understanding the ways of the global business environment. We offer clients availability, quality and efficiency.
  • Developing and sustaining the most talented human resources. We foster teamwork, meritocracy and reward.
