Whistleblower FAQs

Obtaining Legal Representation

Frequently Asked Questions

A whistleblower lawyer is an attorney who represents individuals who report fraud, corruption, or legal violations to government agencies. Whistleblower lawyers advise clients on their rights under laws like the False Claims Act, SEC Whistleblower Program, and Dodd-Frank Act — and pursue financial rewards and anti-retaliation protections on their behalf.

A qui tam lawsuit is a legal action filed under the False Claims Act by a whistleblower — known as a relator — on behalf of the U.S. government against an entity committing fraud against federal programs. The whistleblower receives 15–30% of funds the government recovers. KKC’s qui tam lawyers have recovered hundreds of millions under the FCA.

Blowing the whistle is serious business. Your job, reputation, and career may be on the line. Your first priority should be to find a whistleblower lawyer. Not all whistleblower disclosures are lawful or protected. You need to know how to blow the whistle and protect yourself. Moreover, many whistleblower laws permit you to obtain a financial reward. It is essential that when you blow the whistle, you understand your rights.

The three founding partners of our firm have exclusively represented whistleblowers since 1984 (Stephen Kohn), 1985 (Michael Kohn) and 1988 (David Colapinto). Our managing partner, Mary Jane Wilmoth, joined the firm in 1993.

The firm’s record on winning whistleblower cases is second to none. We obtained the largest award ever given to an individual whistleblower, won numerous reward and retaliation cases, and have worked with Congress and executive agencies in drafting the laws and rules governing whistleblowers.

Our partners have written the most books published on whistleblower laws. In 1988 the firm’s partners helped to found the National Whistleblower Center, and they are highly committed to advocating pro bono for whistleblowers. We’ve successfully established many of the whistleblower laws, regulation, and legal precedents that now benefit all whistleblowers.

In the United States, many whistleblower attorneys work for a “contingency” fee. If the whistleblower loses his or her case, the whistleblower does not have to pay the attorney any money. But if the whistleblower wins the case, their attorney will generally obtain a contingency fee of between 30-40%. Additionally, many whistleblower laws have “statutory fee” provisions. Under these provisions, if the whistleblower wins, the company must pay all “reasonable” attorney fees incurred on behalf of the client.

Finally, although many whistleblowers have a “contingency fee” arrangement, many firms will charge a whistleblower an hourly fee. There are many reasons that firms charge such a rate. Having to pay an attorney a fee is not a good reason to reject retaining legal representation. It is Kohn, Kohn and Colapinto’s general practice to represent whistleblowers on a contingency fee basis.

Outside of the United States, most attorneys charge their clients fees. However, the United States has a different pay-model based on a contingency fee (see above). Thus, international whistleblowers who retain attorneys in the United States often do not have to pay any up-front attorney fees. For more information about attorney fees, please refer to our standard whistleblower attorney fees resource page.

The whistleblower lawyers of the law firm of Kohn, Kohn and Colapinto all have over 30 years of experience representing whistleblowers. If KKC agrees to represent you, one of our partners will manage your case. This hands-on approach by KKC partners makes it very difficult for the law firm to represent all of the whistleblowers who contact our firm. A founding partner does review every intake form received through the contact form on our website.
