What Is a Relator? Meaning in False Claims Act Cases

A relator is the private person who brings a qui tam action under the False Claims Act. The word comes from the Latin phrase describing someone who pursues a claim for the sovereign as well as for themselves.

In everyday terms, the relator is the whistleblower — often an employee, contractor, or insider who witnessed fraud against federal programs and works with counsel to file a sealed complaint.

In a typical civil lawsuit, the injured party is the plaintiff. In qui tam litigation, the United States is the real party in interest, and the relator stands in the government's shoes for purposes of the case.

If the government intervenes, it may take over primary control of litigation while the relator remains a party entitled to a share of any recovery.

Relators generally need firsthand knowledge of fraud, not mere suspicion. They must file under seal, serve the government, and comply with heightened pleading rules.

Eligibility limits apply: certain government officials, participants in the fraud, and those whose claims are barred by public disclosure or first-to-file rules may not qualify.

If the case succeeds, the relator may receive a court-approved share of the recovery — often roughly 15 to 25 percent when DOJ intervenes, or 25 to 30 percent when the government declines and the relator wins.

The relator and relator's counsel typically cooperate with government investigators during the seal period and may remain involved through settlement or trial.

If you recognize patterns described in this guide — especially repeated conduct backed by documents or witness knowledge — consider speaking with counsel experienced in False Claims Act litigation. Initial consultations are usually confidential; use personal phone or email, not employer systems.
