US-Based Litigation Law Firm in São Paulo

Experienced US Litigation Counsel Serving Clients in São Paulo

Dr. Nick Oberheiden
Attorney Nick OberheidenBrazilian Companies and Executives
Litigation Team Lead

Oberheiden P.C. is a US-based law firm that represents international clients in complex civil and governmental litigation across the United States. We represent Brazilian businesses and other Brazilian clients based in São Paulo in a broad range of cross-border disputes, from commercial disputes between private parties to disputes with the US government.

If you are looking for a US-based litigation law firm in São Paulo, we invite you to get in touch to discuss how we can help. We provide strategic advice and representation for complex and high-stakes legal matters in the US, and we work with clients throughout Latin America and around the world. We handle international litigation and arbitration in jurisdictions across the country—from Miami to New York and from Los Angeles to Washington DC—and our lawyers are available to provide representation on an emergency basis when necessary.

Matters We Handle for Clients in Latin America

Within our Latin America practice, we represent clients in São Paulo (SP), Brazil in all types of litigation in the United States. This includes, but is not limited to, representing Brazilian companies, financial institutions, investors, and other clients in disputes involving:

Capital Markets

We represent clients in disputes involving capital markets offerings in the United States and Brazil. This includes defending Brazilian issuers of capital markets offerings against claims from US parties and representing Brazilian clients as plaintiffs in capital markets litigation. We have advised lenders and corporate clients in connection with a wide range of capital markets transactions, and we leverage this experience as litigation counsel.

International Financing

We handle all types of international financing litigation in jurisdictions across the United States. While we may not have the global footprint of the world’s largest law firms, we have a strong presence and reputation in the United States, and we rely on our lawyers’ deep experience to provide strategic, efficient, and effective legal representation.

Mergers and Acquisitions

Our lawyers represent Brazilian clients in US litigation involving cross-border mergers and acquisitions (M&A). We handle disputes arising at all stages of the M&A process and involving all parties. Whether your company is facing a dispute that is local to our Houston headquarters or anywhere else in the United States, we have the resources and capabilities required to assist.

Private Equity Disputes

Our lawyers also represent Brazilian clients in US litigation involving cross-border private equity disputes. This includes representing Brazilian investors and representing Brazilian companies with US investors in contract disputes, corporate governance disputes, takeover litigation, and other types of litigation involving private equity transactions.

Project Finance

We handle project finance litigation in the US on behalf of Brazilian companies in São Paulo as well. From fund formation through project execution, we handle litigation at all stages of the project finance lifecycle; and, here too, we rely on deep experience to strategically and efficiently pursue favorable outcomes that protect our clients’ financial and business interests going forward.

Other Business Transactions and Investments

We also handle litigation in the US involving all other types of business transactions and investments. From restructuring transactions to large corporate partnerships and joint ventures, our law firm is able to serve as US litigation counsel for Brazilian companies, banking institutions, and other clients facing transaction-related disputes with US counterparts across the United States.

Other Business Disputes

Along with litigation involving business transactions and investments, we handle litigation involving all other types of business disputes as well. This includes, but is not limited to:

  • Artificial intelligence litigation
  • Intellectual property litigation
  • Real estate litigation
  • Trade and counterfeiting litigation
  • Judgment enforcement litigation

Again, these are just examples. If your company is facing any type of business dispute in the US, we can provide effective legal representation in court. We also handle pre-litigation dispute resolution negotiations, and we rely on our experience to help our clients target resolutions that preserve business relationships and avoid courtroom litigation when warranted. We handle international mediation and arbitration involving complex business disputes as well.

Government Investigations

Beyond commercial litigation, we also have substantial experience representing domestic and foreign clients in litigation arising out of government investigations. This includes, but is not limited to:

  • Anti-bribery and corruption litigation
  • Antitrust and securities litigation
  • Import-export litigation
  • OFAC sanctions litigation
  • Tax litigation

Government investigations can present substantial risks. The US government leverages its substantial resources and relationships with international law enforcement partners to aggressively target entities and individuals suspected of violating US law. Defending clients during government investigations and enforcement proceedings is a substantial portion of our practice, and our team includes former federal prosecutors and federal agents who have first-hand knowledge of the government’s investigative and litigation tactics, strategies, and priorities.

Why Choose Oberheiden P.C. for Complex Litigation in the US?

Litigating complex disputes with private parties or the US government requires highly skilled and knowledgeable legal counsel. It also requires legal counsel with the ability to communicate clearly and effectively, and with a commitment to securing favorable results in extremely high-stakes scenarios. Here are some of the reasons why Brazilian clients choose Oberheiden P.C.:

  • Fluent in Portuguese – We have attorneys, including Founding Attorney Nick Oberheiden, PhD, who are fluent in Portuguese. As a result, we are able to communicate clearly and effectively with our Brazilian clients and their São Paulo-based lawyers, and we are able to translate complex legal and financial matters across borders.
  • Knowledgeable About Brazilian Law – Founding Attorney Nick Oberheiden, PhD is also knowledgeable about Brazilian law, and he relies on this knowledge when advising clients from São Paulo, Rio de Janeiro, and elsewhere. Dr. Oberheiden served as a visiting lawyer at the Supreme Court of Brazil and has made academic visits to São Paulo and Rio de Janeiro as well.
  • Deep Experience in US Litigation – We have deep experience in US litigation involving all of the types of disputes discussed above. We focus our practice on litigating complex disputes in federal court, and our experience spans an extremely broad range of disputes, industries, and clients.  
  • Recognized Authorities in the Field – Several of our senior attorneys are recognized authorities in the field of complex federal litigation. This includes Dr. Oberheiden, who has been featured by national media outlets including Forbes Magazine and The Wall Street Journal, among many others.
  • Team of Senior-Level Attorneys – Unlike many large international law firms that employ teams of junior associates, all of our attorneys have senior-level experience. All of our attorneys have represented clients in a wide range of industries, and many of our attorneys come from backgrounds working for the US Department of Justice (DOJ).
