Employees of financial institutions, investment firms, publicly traded companies, and other businesses in London can serve as whistleblowers under U.S. law. Similar to the United Kingdom, the United States has enacted whistleblowing legislation that allows current (and former) employees to expose financial fraud and other forms of alleged wrongdoing to the government—and potentially become eligible to receive substantial whistleblower rewards.
At Oberheiden P.C., we help whistleblowers in London and throughout the United Kingdom report wrongdoing under U.S. law. Our attorneys handle whistleblowing cases involving all forms of financial fraud, from anti-money laundering and international sanctions violations to corporate accounting violations and broker-dealer conflicts of interest. We handle cases involving bribery and corruption as well; and, in all cases, we report wrongdoing to the appropriate federal authorities directly on our client’s behalf.
Types of Cross-Border Whistleblowing Claims We Handle
Our attorneys assist with the disclosure of all forms of financial fraud under U.S. law. We represent whistleblowers in the United Kingdom and around the world who are eligible to file complaints involving allegations including (but not limited to):
- Anti-Money Laundering (AML) Violations – We represent whistleblowers who have information about anti-money laundering (AML) violations committed by their employers and other organisations. This includes (but is not limited to) violations of the federal Bank Secrecy Act (BSA).
- Bribery and Corruption – We also represent whistleblowers who have information about violations of the federal Foreign Corrupt Practices Act (FCPA) and other forms of unlawful bribery and corruption. Whistleblowers can report violations by companies, government officials, and other individuals.
- Corporate Fraud – We help whistleblowers in London report all forms of corporate fraud to U.S. governmental authorities. This includes corporate insiders as well as outside professionals who have information about accounting irregularities and other improper corporate practices.
- Gaming and Gambling Fraud – Gaming and gambling fraud are growing concerns in the United States, and the U.S. Department of Justice (DOJ) has prioritized these cases recently. If you have information about fraudulent sports betting, event contract fraud, or any other form of gaming or gambling fraud, our lawyers can explain what you need to know about the U.S. whistleblowing process.
- Fraud Against Financial Institutions – We help whistleblowers expose fraud committed against financial institutions—from loan fraud to abuse of offshore tax shelters. Our team of whistleblower attorneys has extensive experience in this area.
- Fraud By Financial Institutions – We also have extensive experience in cases involving fraud committed by financial institutions. This includes fraud perpetrated against consumers as well as fraud committed against the U.S. government.
- Government Fraud – We also help whistleblowers in London report fraud under U.S. government contracts, grants, and programs. The U.S. government relies heavily on whistleblowers to expose these forms of fraud, especially overseas, and we support whistleblowers in holding their employers and other organisations accountable.
- Investment Fraud – A significant portion of our international whistleblower practice involves reporting investment fraud to the U.S. Securities and Exchange Commission (SEC) and U.S. Commodity Futures Trading Commission (CFTC). We support whistleblowers who are eligible to file complaints in relation to fraud perpetrated by issuers, broker-dealers, and other entities.
- OFAC Sanctions Violations – We advise and represent UK whistleblowers in cases involving Office of Foreign Assets Control (OFAC) sanctions violations as well. If you have information about an OFAC sanctions violation, our attorneys can provide the advice you need to make informed decisions about your next steps.
- Tax Fraud – We also assist whistleblowers in the UK with exposing federal tax fraud to the Internal Revenue Service (IRS). While the IRS’s career revenue agents and fraud investigators have substantial expertise in all areas of U.S. tax compliance, they too rely heavily on whistleblowers to come forward.
These are just examples. If you believe that you have information about any breach of a company’s or financial institution’s obligations under U.S. law, we strongly encourage you to get in touch. Whether it makes sense for you to file a complaint with a governmental authority like the SEC or file a qui tam complaint in federal court, our London, UK whistleblower attorneys can help you make informed decisions and move forward with confidence.
Why Should You Report a Violation of U.S. Law in the United Kingdom?
If you live and work in the United Kingdom, why should you report a violation of U.S. law? Some of the most important reasons to serve as a whistleblower in this scenario include:
Protecting the Public Interest in the United Kingdom
Violations of U.S. law don’t just impact people in the United States. They also impact people on the other side of the pond and around the world.
Holding Senior Executives and Other Bad Actors Accountable
When senior executives and other bad actors engage in fraud, they deserve to be held accountable. U.S. law allows for both civil and criminal enforcement in appropriate cases.
Deterring Future Financial Fraud
Holding bad actors accountable also helps to deter financial fraud in the future. Those who are held accountable for fraud are less likely to commit fraud again.
Eligibility for U.S. Whistleblower Rewards
In many cases, individuals who come forward under U.S. whistleblowing legislation will become eligible for financial rewards. These awards can be sizable in many cases.

FAQs: Exposing Financial Fraud Under U.S. Law as a Whistleblower in the United Kingdom
What Information or Evidence Do I Need to Serve as a Financial Fraud Whistleblower Under U.S. Law?
You do not need any specific type or volume of information or evidence to serve as a financial fraud whistleblower under U.S. law. If you have credible information about a potential violation of U.S. law, we strongly encourage you to speak with one of our lawyers about coming forward.
Do I Have to Be a U.S. Citizen to Participate in U.S. Whistleblower Reward Programs?

Should I Hire a Lawyer in the U.S. or a Solicitor in the United Kingdom to File a Whistleblower Complaint Under U.S. Law?
When choosing a whistleblower lawyer to represent you, relevant experience is the most important factor. U.S. whistleblower cases are complex, and there are strict requirements you need to meet in order to qualify for protection and potentially compensation under U.S. whistleblower laws. As a result, you should focus on choosing a lawyer who has experience helping whistleblowers come forward.
Are There Any Risks Involved with Filing a Whistleblower Complaint in the U.S.?
Whistleblowers are entitled to strong protections under U.S. law, including confidentiality (or anonymity in some cases) and protection against retaliation. While it is unlikely, if you experience discrimination in the workplace, an unfair dismissal, or any other form of unfair treatment or retaliation after blowing the whistle, you will have clear legal rights.
