Qui Tam Lawsuits in Plain English: What a Relator Actually Does

“Qui tam” is Latin shorthand for a phrase that translates roughly to “he who sues for the king as well as for himself,” and that translation is a better plain-English definition than most law firm websites offer. You are not filing a complaint with a regulator and waiting. You are suing on the government’s own behalf, in the government’s name, with your own name attached, and if the case succeeds you keep a slice of what it recovers. Fiscal year 2025 set records on both ends: whistleblowers filed 1,297 qui tam suits, the most in the statute’s history, and settlements and judgments hit $6.8 billion. Since Congress strengthened the law in 1986, total recoveries now top $85 billion. Here is what a relator actually does, day one to payout.

What a relator is, and why you cannot do this alone

A relator is the private citizen bringing the suit, and anyone with knowledge of fraud against a federal program can be one, even without having personally lost a dollar. But you cannot file this yourself. Courts have consistently held that a relator must be represented by an attorney, since you are asserting the government’s claim as well as your own, and a non-lawyer cannot represent another party’s interest in federal court. That rule holds whether you plan to stay quiet about the case or not; there is no do-it-yourself track here, full stop.

Two doctrines can end a case before it starts, and both matter more than most first-time relators expect. The first-to-file bar means once one relator files on a given set of facts, no later relator can bring a related case on the same facts, even with stronger evidence. The public disclosure bar requires dismissal of a case based on allegations already publicly disclosed, through a government report, hearing, audit, or news coverage, unless you qualify as an original source: someone with independent knowledge that materially adds to what was already public, who gave that information to the government before filing. Build a case entirely out of news articles and court records you did not generate, and the public disclosure bar can end it regardless of how solid the underlying fraud looks.

Filing under seal: the part that surprises people

Once your attorney files, the complaint goes into the court in camera and under seal, alongside a confidential written disclosure statement laying out substantially all the material evidence you have. That disclosure statement never gets filed publicly and never goes to the defendant. Instead, a copy goes only to the U.S. Attorney for that district and to the Attorney General in Washington. The company you are suing does not receive the complaint, and does not know the case exists.

The seal has to last at least 60 days while the government investigates, but in practice the government routinely asks for, and gets, extensions for good cause, so cases regularly stay sealed far longer than two months. While it is sealed, you generally cannot discuss the case publicly, not with coworkers, not with family, not with the press, because doing so can jeopardize the case and your own position in it.

The decision that sets your math: intervene or decline

At the end of the seal period, the government makes a call that determines both how the case gets litigated and what you eventually collect if it wins.

If the government intervenes, it takes over as the lead plaintiff, brings its own investigative and litigation resources, and your relator’s share settles into 15% to 25% of whatever the government recovers.

If the government declines, your attorney can still pursue the case alone, without government resources, and your potential share rises to 25% to 30% of the recovery if you win. A court can also cap the share at 10% regardless of which path you are on if the case rests mainly on information that was already publicly disclosed, even for a relator who otherwise qualifies as an original source. This same 15% to 30% range, with the same 10% cap, is what the qui tam / False Claims Act program page lists as the official reward structure.

A decline is not a verdict on the merits of your case. It usually reflects the government’s own capacity and priorities as much as anything about your evidence. But it changes the odds meaningfully, because your attorney now has to build and prove the case without a U.S. Attorney’s subpoena power behind it, and declined cases settle or win less often as a result. Treating a declined case as automatically lost is a mistake, but so is assuming a decline changes nothing about your path forward.

Realistic outcomes: most declined cases do not pay

The honest version of the math looks like this: the government intervenes in a minority of the qui tam suits filed each year, and the large majority of the recoveries reported each fiscal year, including most of the $6.8 billion in fiscal 2025, comes from cases the government chose to run itself or settle with its own leverage behind the relator. When the government declines, most of those cases do not go on to produce a recovery at all. Your attorney is asking a defendant, or a court, to pay out serious money without the credibility of a federal prosecutor standing behind the claim, and a large share of declined cases are eventually dismissed, settled for far less than hoped, or simply abandoned when the evidence will not carry the case alone.

None of this means a declined case is worthless. It means you should walk in with a realistic sense of the odds rather than assuming every qui tam filing that survives the seal turns into a payout. Ask your attorney directly, before you file, how they assess the odds if the government declines, and what the case looks like if you are the one carrying it.

What actually gets paid, and the liability driving it

The underlying exposure is steep by design: three times the government’s actual damages, plus a per-claim civil penalty currently running $14,308 to $28,619, applied separately to every individual false claim submitted. In a case built on thousands of billing submissions, the penalty stack alone can dwarf the actual damages, which is part of why healthcare fraud dominates the numbers. Of the $6.8 billion recovered in fiscal 2025, more than $5.7 billion involved health care fraud, chiefly Medicare, Medicaid, and TRICARE billing.

Your relator’s share is calculated against what the government actually recovers, not the headline liability number, and a successful relator is also typically entitled to reasonable expenses, litigation costs, and attorney’s fees, paid separately by the defendant rather than carved out of your own percentage. See how much whistleblowers actually get paid for how this compares to the SEC and CFTC’s reward programs.

Timeline reality

There is no fixed post-decision claim deadline the way the SEC and CFTC give you 90 days to file after a Notice of Covered Action. Instead, the whole front end is open-ended: the seal period alone commonly runs well past a year once extensions are factored in, then investigation, then a decision to intervene or decline, then litigation or settlement, then a court determining your exact percentage inside the statutory range. Three to six years from filing to resolution is common, and complex health care or defense-contracting cases can run longer.

Common mistakes

Waiting to find a lawyer. You cannot file this yourself, and the strength of the disclosure statement built before filing matters more than speed.

Talking about the case while sealed. This can tip off the defendant or jeopardize the case entirely.

Assuming you have time. The first-to-file bar shuts out every later relator the moment someone else files on the same facts.

Building the case only on public records. The public disclosure bar can end a strong-looking case unless you can show you are an original source with material, independent knowledge.

Bringing tax fraud here. The False Claims Act explicitly excludes claims made under the Internal Revenue Code. If the underlying wrongdoing is tax underpayment rather than false billing to a federal program, use the IRS whistleblower program and Form 211 instead.

If your employer also retaliated against you for raising any of this internally, that runs on its own separate clock and its own remedies. Read whistleblower retaliation protections explained for the three-year window that applies specifically to qui tam retaliation, and do you need a whistleblower lawyer before you approach one, since the attorney requirement here is not optional.
