What Is a Qui Tam Lawsuit?

A qui tam lawsuit is a legal action brought by a private citizen — known as a relator — on behalf of the United States government against a person or company that has defrauded the government. The term "qui tam" comes from the Latin phrase "qui tam pro domino rege quam pro se ipso in hac parte sequitur," meaning "he who sues in this matter for the king as well as for himself."

Under the False Claims Act (FCA), codified at 31 U.S.C. §§ 3729–3733, private citizens who discover fraud against the federal government can file a lawsuit and, if successful, receive a significant portion of the recovered funds — typically 15% to 30% of the total recovery.

Since 1986, qui tam lawsuits have recovered over $72 billion for the federal government, making them the single most effective tool for combating government fraud.


How Does the False Claims Act Work?

The False Claims Act is the federal government's primary weapon against fraud. It prohibits:

  1. Knowingly presenting false claims for payment to the government (§ 3729(a)(1)(A))
  2. Making false statements material to a false claim (§ 3729(a)(1)(B))
  3. Conspiring to violate the False Claims Act (§ 3729(a)(1)(C))
  4. Reverse false claims — avoiding an obligation to pay the government (§ 3729(a)(1)(G))

The word "knowingly" is key. Under the FCA, a person acts knowingly if they:

No specific intent to defraud is required. This lower standard means that companies cannot hide behind claims of ignorance when they should have known about fraud occurring within their operations.

Penalties Under the False Claims Act

Violators face significant financial penalties:

For large government contracts, these penalties can reach into the hundreds of millions or even billions of dollars.


Who Can File a Qui Tam Lawsuit?

Almost anyone can file a qui tam lawsuit, including:

Key Requirements

To file a successful qui tam lawsuit, you generally need:

  1. Original information — You must have knowledge of fraud that hasn't already been publicly disclosed
  2. Federal government involvement — The fraud must involve federal funds (Medicare, defense contracts, federal grants, etc.)
  3. Specificity — You need enough detail to demonstrate that false claims were submitted
  4. Timeliness — The statute of limitations is 6 years from the violation, or 3 years from when the government knew or should have known (up to 10 years total)

Who Cannot File?

There are limited exceptions. You typically cannot file if:


The Qui Tam Process: Step by Step

Step 1: Gather Evidence

Before filing, it's critical to document the fraud thoroughly:

Step 2: Consult a Qui Tam Attorney

Qui tam cases are complex. An experienced False Claims Act attorney will:

Most qui tam attorneys work on contingency — they don't charge upfront fees but take a percentage of the recovery.

Step 3: File Under Seal

The complaint is filed in federal court under seal, meaning it remains secret. You also provide a disclosure statement with all relevant evidence to the Department of Justice (DOJ).

The seal period typically lasts 60 days but is almost always extended — sometimes for years — while the government investigates.

Step 4: Government Investigation

During the seal period, the DOJ investigates the allegations. This may include:

Step 5: Government Decision

After investigating, the DOJ makes a critical decision:

Step 6: Resolution

Cases can resolve through:


Whistleblower Rewards: How Much Can You Receive?

The False Claims Act provides significant financial incentives:

ScenarioRelator's Share
Government intervenes15% to 25% of the recovery
Government declines, relator proceeds25% to 30% of the recovery

Real Examples of Whistleblower Awards

The average qui tam recovery in cases where the government intervenes is approximately $4.8 million, though amounts vary enormously based on the scope of the fraud.

Frequently Asked Questions

How long does a qui tam case take?

Most cases take 2 to 7 years from filing to resolution. The seal period alone can last 1-3 years while the government investigates.

Can I file anonymously?

The complaint is filed under seal, so the defendant does not learn your identity during the investigation phase. However, your identity will eventually be disclosed if the case proceeds.

Do I need a lawyer?

While technically you can file without an attorney, it is strongly recommended to work with an experienced qui tam lawyer. The legal process is complex, and attorneys work on contingency so there's typically no upfront cost.

What if my employer fires me for reporting fraud?

The False Claims Act includes strong anti-retaliation provisions. You may be entitled to reinstatement, double back pay, and compensation for damages.

Can I file a qui tam case about state government fraud?

Many states have their own False Claims Acts. Currently, 31 states plus the District of Columbia have state-level qui tam statutes. QuitamAI primarily focuses on federal cases, but the analysis tools can help identify state-level fraud as well.

What if the government declines to intervene?

You can still pursue the case independently. While success rates are lower without government intervention, many relators have achieved significant recoveries on their own.

How is the qui tam reward calculated?

The reward is based on the total amount recovered by the government — including settlements, judgments, and penalties. The percentage (15-30%) depends on whether the government intervened and the significance of your contribution.
