Qui Tam Lawsuit: How Whistleblowers Sue for the Government - and What They Keep
A qui tam lawsuit lets a private person (the “relator”) sue a fraudster on behalf of the United States and keep 15-30% of what is recovered. In fiscal 2025 those suits drove a record $6.8 billion in False Claims Act recoveries. Here is how the process actually works, step by step.

What a Qui Tam Lawsuit Is
The False Claims Act (31 U.S.C. §§ 3729-3733) makes it unlawful to knowingly submit false claims for government money - inflated Medicare bills, defective goods sold to the military, customs evasion. Its qui tam provisions let a whistleblower with inside knowledge file suit in the government's name and share in the recovery.
Scale, per the Department of Justice's January 2026 report: over $6.8 billion recovered in FY2025 - the highest ever - with more than $5.3 billion (about 78%) coming from qui tam suits, a record 1,297 new qui tam filings, over $5.7 billion in health-care matters alone, and more than $85 billion recovered since the 1986 amendments.
Case Details
Filed in federal district court under seal: the complaint is served on the government, not the defendant, and stays sealed for at least 60 days (routinely extended, often for a year or more) while DOJ investigates and decides whether to intervene (take over) or decline (the relator may proceed alone).
What the Whistleblower Keeps - § 3730(d)
Who Can File - and the Traps
Anyone with non-public knowledge of fraud against federal programs - employees, contractors, competitors, patients. Three statutory traps decide many cases:
• First-to-file (§ 3730(b)(5)): once a qui tam action is pending, no one else may bring a related action on the same facts - speed matters
• Public-disclosure bar (§ 3730(e)): claims based on allegations already public (hearings, reports, news media) are barred unless you are an “original source” who gave the government the information first
• Retaliation protection (§ 3730(h)): employees, contractors and agents punished for FCA activity can recover reinstatement, double back pay with interest and special damages - within three years of the retaliation
Realistic Timelines - and the Constitutional Cloud
One genuine uncertainty: in U.S. ex rel. Zafirov v. Florida Medical Associates, a Florida district court held the qui tam mechanism unconstitutional under the Appointments Clause; the Eleventh Circuit heard argument December 12, 2025 and - as far as public reporting shows - had not ruled as of August 2026. The statute remains in force everywhere, but the challenge is live.
How a Qui Tam Case Moves
- 1
Counsel and Disclosure
The relator retains FCA counsel and prepares a written disclosure of material evidence for DOJ - essential to original-source status.
- 2
Sealed Filing
Complaint filed in camera; sealed for 60+ days (extensions routine); defendant not yet served.
- 3
Government Investigation
DOJ (often with the relevant agency's inspector general) investigates, may issue civil investigative demands, and interviews the relator.
- 4
Intervene or Decline
Intervention: DOJ leads and the relator gets 15-25%. Declination: the relator may litigate alone for 25-30% - or dismiss.
- 5
Resolution and Award
Most recoveries come by settlement; the relator's share is set within the statutory band based on contribution, plus fees and expenses.
Cautions
Three ways qui tam goes wrong for whistleblowers:
Going public first
Talking to the press or posting online before filing can trigger the public-disclosure bar. File under seal first; counsel will sequence disclosures.
Waiting
First-to-file means a competitor whistleblower can lock you out. Move promptly once you have evidence.
Expecting a quick check
Years, not months, is the norm - plan for that, and document retaliation from day one (three-year limit under § 3730(h)).
Qui Tam Lawsuit - FAQ
What does 'qui tam' mean?
Short for a Latin phrase meaning one who sues for the king as well as for himself - a private person suing on the government's behalf under the False Claims Act and sharing in the recovery.
How much does a whistleblower get in a qui tam lawsuit?
15-25% if the government intervenes (10% cap for cases built on public information), 25-30% if the relator litigates alone - plus fees and expenses (31 U.S.C. § 3730(d)).
How much did qui tam cases recover last year?
FY2025 (DOJ, January 2026): over $6.8 billion total FCA recoveries - a record - with more than $5.3 billion from qui tam suits and 1,297 new qui tam filings.
How long does a qui tam lawsuit take?
DOJ publishes no statistics; practitioners estimate 2-4 years typically and 5-10 for complex matters, with the sealed phase alone often 1-3 years.
Can my employer fire me for filing?
Retaliation is unlawful under § 3730(h): remedies include reinstatement, double back pay with interest and special damages; sue within three years of the retaliation.
What if someone already filed about the same fraud?
The first-to-file rule generally bars later related actions on the same facts. If you have materially different facts, counsel can assess; otherwise speed is decisive.
Is qui tam constitutional?
It has been for 160+ years, but the Zafirov challenge (Appointments Clause) is pending at the Eleventh Circuit after December 2025 argument. The statute remains in force nationwide; watch that docket.
Separate from this case: were you injured in the last 2 years?
Class-action payouts are fixed amounts through an administrator. A personal injury claim is a different case — and often worth far more. Free estimate, no obligation.
