How to File a Qui Tam Lawsuit in California

What You Need to Know Before Filing a Qui Tam Lawsuit in California
California’s False Claims Act (CFCA), codified at Government Code sections 12650–12656 the California False Claims Act is codified in Government Code sections 12650–12656 (the full range, not just 12650 and 12656) allows a private person called a relator to sue on the state’s behalf when someone defrauds a California government program. Gov. Code § 12652(g) caps the relator’s share at no more than 33 percent of the proceeds if the state or political subdivision goes forth with the action; the 25% upper bound is the federal figure, not California’s. Gov. Code § 12652(g) caps the relator’s share at no more than 50 percent of the proceeds if the state declines to go forth; the statute states a maximum of 50% but does not fix a 25% floor for declined cases the way the article’s ranges imply.
The complaint must be filed under seal in California Superior Court, and a written disclosure of all material evidence must go to the California Attorney General simultaneously. Attorney representation is required both to proceed and to receive any share of the recovery.
What Is a Qui Tam Lawsuit Under California Law?
A qui tam lawsuit is a civil action filed by a private citizen in the name of the state of California against a person or entity that has submitted false claims to a California government program. The term comes from the Latin phrase “qui tam pro domino rege quam pro se ipso in hac parte sequitur,” meaning “who as well for the king as for himself sues in this matter.” The private citizen who brings the suit is the relator. Any private person with firsthand knowledge of the fraud can serve as a relator, not only employees. Vendors, contractors, subcontractors, and even competitors have standing under the CFCA.
The California Attorney General’s False Claims Unit receives the complaint and the accompanying disclosure, investigates, and decides whether the state will take over prosecution. Our whistleblower attorneys work exclusively on a contingency basis, meaning you pay nothing unless there is a recovery.
How the California False Claims Act Differs From the Federal Law
The CFCA is a California statute that operates independently of the federal False Claims Act (31 U.S.C. § 3730). Several features distinguish it. The CFCA does not impose a fixed-day seal period. The federal statute has a 60-day initial seal window, but no equivalent fixed period is established in the California statute; the Attorney General investigates for however long is warranted. California also has a unique inadvertent false claim provision discussed below. § 12653(b)/(c) expressly provides “two times the amount of back pay” (double back pay) along with reinstatement, interest, special damages, and where appropriate punitive damages — so a double back pay remedy IS confirmed under § 12653.
What Conduct Qualifies: The Eight Categories Under § 12651
Government Code § 12651 defines the eight categories of prohibited conduct that give rise to a qui tam action. The CFCA covers fraud against Medi-Cal, state contracts, state grants, and any California government program at the state or political subdivision level.
- Knowingly presenting a false or fraudulent claim for payment or approval to a California government program
- Knowingly making or using a false record or statement that is material to a false or fraudulent claim
- Conspiring with another person to commit any CFCA violation
- Knowingly delivering less than all public property that one has custody of
- Knowingly making a false receipt for public property
- Knowingly buying public property from a person who is not authorized to sell it
- Knowingly making a false record or statement to conceal, avoid, or decrease an obligation to pay money or property to the state or a political subdivision
- Being the beneficiary of an inadvertent false claim and failing to disclose it within a reasonable time after discovery
Common real-world examples include a Medi-Cal provider billing for services never rendered, a contractor submitting inflated invoices on a state construction project, and a grantee falsifying performance data to retain state funding.
California’s Unique Rule: Inadvertent False Claims
Most comparable statutes impose liability only on the person who knowingly submits a false claim. California goes further. Under § 12651, a person who receives a payment through an inadvertent false claim becomes liable if they later discover the error and fail to disclose it to the state within a reasonable time. This means a healthcare organization that discovers an overpayment from Medi-Cal cannot simply keep the funds and say nothing. The failure to self-report after discovery is itself a CFCA violation, independent of any intent at the time of original submission. This provision is frequently overlooked by compliance programs and is a genuine differentiator of California law.
Step-by-Step: How to File a Qui Tam Lawsuit in California
Under Government Code § 12652, the filing procedure is sequential and unforgiving. Missing a step, particularly the simultaneous disclosure requirement, can jeopardize the relator’s right to a share of the recovery. Every step below should be completed with an attorney.
The Filing Checklist: Steps in the Correct Order
- Step 1: Gather and organize your evidence. Compile all documents, records, communications, billing data, and witness information in your possession. The disclosure statement must contain substantially all material evidence you have.
- Step 2: Retain a California attorney experienced in CFCA litigation. Attorney representation is required to proceed and to receive any share of recovery. This is not optional.
- Step 3: Draft the qui tam complaint. The complaint identifies the defendant, describes the fraudulent conduct with particularity, specifies the CFCA provisions violated, and states the harm to California government funds.
- Step 4: Prepare the written disclosure statement simultaneously. This document must contain substantially all material evidence and information in the relator’s possession. It is delivered directly to the California Attorney General, not filed with the court.
- Step 5: File the complaint under seal in California Superior Court. The complaint is sealed on filing. The defendant is not served and has no notice of the lawsuit at this stage.
- Step 6: Deliver the disclosure statement to the Attorney General simultaneously with filing. Timing matters. The disclosure goes to the AG at the same time the complaint is filed with the court.
- Step 7: Wait while the government investigates. The AG or appropriate local prosecuting authority reviews the disclosure and investigates to determine whether to intervene.
- Step 8: Government decision: intervention or declination. The state notifies the court and the relator whether it will take over prosecution (intervene) or leave the relator to proceed independently (decline).
Once filed, the action may be dismissed only with the written consent of both the court and the Attorney General or prosecuting authority. A relator cannot simply walk away without that approval.
The Written Disclosure Statement: What It Is and Why It Matters
The disclosure statement is separate from the complaint and serves a distinct function. It gives the government a complete factual picture of the fraud before the case becomes public. It must contain substantially all material evidence in the relator’s possession at the time of filing. Courts have treated deficient disclosure statements as a ground to challenge a relator’s right to a share of the recovery. The statutory text places the public-disclosure bar at § 12652(d)(3)(B) and DEFINES ‘original source’ at § 12652(d)(3)(C); the definition of original source lives in subparagraph (C), not (B).
What Happens After Filing: Government Intervention or Declination
If the state intervenes, it assumes primary responsibility for prosecuting the action. The relator remains a full party and retains the right to participate in the litigation, though the government leads. If the state seeks to dismiss the case after intervention, it must notify the relator, who has the right to oppose the motion and present evidence at a hearing before the court rules. If the state declines to intervene, the relator may proceed independently, but the recovery is harder to achieve and the financial exposure falls entirely on the relator’s legal team.
The trade-off is a higher potential relator share — Gov. Code § 12652(g) caps the relator’s share at no more than 50 percent of the proceeds if the state declines to go forth; the statute states a maximum of 50% but does not fix a 25% floor for declined cases the way the article’s ranges imply — compared to the intervention scenario — Gov. Code § 12652(g) caps the relator’s share at no more than 33 percent of the proceeds if the state or political subdivision goes forth with the action; the 25% upper bound is the federal figure, not California’s.
Understanding how this process compares to other California enforcement mechanisms, such as the Private Attorneys General Act, can help you decide which path fits your situation. See our guide on how to file a PAGA lawsuit in California for a detailed comparison of that parallel system.
How Much Can a Qui Tam Relator Recover in California?
| Scenario | Relator’s Share of Recovery | Who Leads Prosecution |
|---|---|---|
| State intervenes and the case succeeds | Gov. Code § 12652(g) caps the relator’s share at no more than 33 percent of the proceeds if the state or political subdivision goes forth with the action; the 25% upper bound is the federal figure, not California’s | California AG or local prosecuting authority |
| State declines and the relator wins independently | Gov. Code § 12652(g) caps the relator’s share at no more than 50 percent of the proceeds if the state declines to go forth; the statute states a maximum of 50% but does not fix a 25% floor for declined cases the way the article’s ranges imply | Relator’s own legal team |
In addition to the relator’s share, defendant employers are required to pay the relator’s reasonable attorney fees and litigation costs if the case succeeds. Recoveries are deposited into the False Claims Act Fund in the State Treasury under § 12652(j), which is then used to fund future CFCA investigations and prosecutions.
Treble Damages and Per-Claim Penalties Explained
The CFCA imposes liability at three times the government’s actual loss, a multiplier called treble damages. On top of that, the court may impose civil penalties of $5,500 to $11,000 per individual false claim submitted. Those two figures are additive and apply claim by claim. In a Medi-Cal billing fraud case involving thousands of false submissions over multiple years, the per-claim penalties alone can exceed the base damages figure. A relator’s share is calculated as a percentage of the total recovery, which includes both the treble damages and all per-claim penalties collected.
Consider this illustrative scenario: a durable medical equipment company submits 2,000 false Medi-Cal claims over three years, each overstated by $500, for a total overbilling of $1,000,000. Treble damages would be $3,000,000. Civil penalties at $5,500 per claim would add another $11,000,000. Total potential liability: $14,000,000. At a 20% relator share in an intervention case, the relator would recover $2,800,000 before attorney fees. This is an illustrative example only, not a prediction of any specific outcome.
How Long Do You Have to File: Statute of Limitations Under § 12654
Under Government Code § 12654, three limitation periods apply, and the case must be filed before whichever of the first two occurs last, subject to the absolute outer limit of the third.
- Six-year rule: The action must be filed no more than six years after the date the § 12651 violation occurred.
- Three-year discovery rule: The action must be filed no more than three years after the date the Attorney General or appropriate prosecuting authority knew or reasonably should have known the material facts.
- Ten-year absolute ceiling: In no event may the action be filed more than ten years after the date of the violation, regardless of when anyone learned of it.
The ten-year ceiling is not an invitation to delay. Evidence goes stale, witnesses become unavailable, and the disclosure statement must reflect what you know now. § 12654 also provides that if a criminal proceeding produces a guilty verdict (whether after trial or on a guilty plea) charging false statements or fraud arising from the same transaction, the defendant is estopped from denying the essential elements of that offense in a subsequent CFCA civil action. This criminal estoppel provision can significantly simplify the civil case when a parallel criminal prosecution has already succeeded.
Whistleblower Protections: What Happens If Your Employer Retaliates?
Government Code § 12653 prohibits employers from retaliating against any employee, contractor, or agent because of lawful acts taken in furtherance of a CFCA action or in reporting potential CFCA violations. § 12653(b)/(c) expressly provides ‘two times the amount of back pay’ (double back pay) along with reinstatement, interest, special damages, and where appropriate punitive damages so a double back pay remedy IS confirmed under § 12653 [source]. If you were fired, demoted, suspended, harassed, or otherwise discriminated against because you reported fraud or assisted in a CFCA investigation, § 12653 provides a separate cause of action independent of the qui tam suit itself. For a broader overview of protections available to workers who report illegal conduct, see our article on what to know about a class action lawsuit in California for context on how coordinated claims can sometimes work alongside individual whistleblower actions.
A common employer tactic is to characterize the termination as a performance-based or restructuring decision with no connection to the employee’s reporting activity. The statutory protection applies to the protected conduct, not merely to formal qui tam filings, so internal reports and informal disclosures to supervisors or compliance departments can qualify as protected activity if they were taken in furtherance of a CFCA action.
Do You Need an Attorney to File a Qui Tam Lawsuit in California?
Yes, without exception. The California Attorney General’s office confirms that attorney representation is required both to proceed with a CFCA action and to receive any share of the recovery. A relator who attempts to file pro se cannot collect a relator’s share even if the case ultimately succeeds. Beyond the legal requirement, the disclosure statement, the seal procedure, the preservation of original-source status the statutory text places the public-disclosure bar at § 12652(d)(3)(B) and DEFINES ‘original source’ at § 12652(d)(3)(C); the definition of original source lives in subparagraph (C), not (B) and the anti-retaliation protections under § 12653 all require precise execution. A procedural error at the filing stage can permanently forfeit the relator’s right to participate in the recovery.
What This Means If You Witnessed Fraud Against a California Program
If you have firsthand knowledge of false claims submitted to Medi-Cal, a state contract, or any California government program, the clock under § 12654 is already running from the date of each violation. Your most urgent task is not to report internally or confront the employer but to consult a California attorney who can assess whether your evidence satisfies the disclosure standard and preserve your original-source status before someone else files first on the same conduct. If your employer has already retaliated against you for raising concerns, § 12653 gives you a separate claim that can proceed alongside the qui tam case. The financial stakes in a successful CFCA action are substantial, and the procedural requirements are precise enough that a misstep at the filing stage can eliminate rights that cannot be recovered later.
Frequently Asked Questions
Can I file a qui tam lawsuit anonymously?
The complaint is filed under seal, so the defendant does not know about the lawsuit during the investigation phase. However, your identity is disclosed to the California Attorney General through the disclosure statement from the beginning. If the case proceeds to litigation after the seal is lifted, your identity as the relator becomes part of the court record.
What if someone else has already filed a qui tam lawsuit about the same fraud?
Government Code § 12652 contains a first-to-file rule. If a related action is already pending when you attempt to file, the court may bar your case. This is another reason to consult an attorney immediately rather than waiting to gather more evidence.
Does the CFCA cover fraud against federal programs administered by California agencies?
The CFCA covers fraud against California state or political subdivision funds. Fraud against purely federal programs, such as Medicare (as opposed to Medi-Cal), falls under the federal False Claims Act rather than the CFCA. Many healthcare fraud cases involve both state and federal funds simultaneously, and a California attorney can assess which statute applies to the specific conduct you witnessed.
How long does a qui tam case typically take?
The bundle does not contain verified data on average case duration, and stating a specific timeline would not be accurate. Government investigations vary significantly in length depending on the complexity of the fraud, the volume of evidence, and the AG’s current caseload. Cases that proceed to full litigation after intervention can take several years to resolve.
What is the False Claims Act Fund?
Under § 12652(j), proceeds recovered by the California Attorney General through CFCA actions and settlements are deposited into the False Claims Act Fund in the State Treasury. Upon legislative appropriation, those funds are used to support the ongoing investigation and prosecution of false claims against California government programs.
