How Long Do You Have to Sue for Fraud in California, and When Does the Clock Start?

Last updated: November 2026. Reviewed by Pavel Kolmogorov, California business litigation attorney (State Bar No. 321018).

Not necessarily. The statute of limitations for fraud in California is three years, and under Code of Civil Procedure section 338, subdivision (d), the claim does not accrue until the aggrieved party discovers the facts constituting the fraud. If you learned of the falsified books only recently, the real question is whether you should have discovered them sooner. Courts start the clock when you had reason to suspect wrongdoing. Kolmogorov Law, P.C. handles newly discovered and long-past fraud claims in Orange County, Los Angeles, and across California.

The three-year rule and its discovery clause

The statute is short. An action for relief on the ground of fraud or mistake must be brought within three years. The cause of action is not deemed to have accrued until the discovery, by the aggrieved party, of the facts constituting the fraud or mistake. (Code Civ. Proc., § 338, subd. (d).)

So the date of the fraud is only the starting point of the analysis. Five years after the act can still be timely. Everything turns on what discovery means.

Inquiry notice: when you should have known

Discovery does not mean proof. It does not even mean knowledge.

Under California's discovery rule, a claim accrues when the plaintiff discovers, or has reason to discover, the cause of action. A plaintiff has reason to discover when there is reason at least to suspect a factual basis for the claim. From that point the plaintiff must investigate with reasonable diligence and is charged with knowing whatever that investigation would have revealed. (Fox v. Ethicon Endo-Surgery, Inc. (2005) 35 Cal.4th 797.)

In a business dispute, the defense looks for the first red flag. A tax document that did not match the distributions. An accountant's email questioning an entry. A bank calling about an unfamiliar account. A partner who stopped sharing monthly statements. Any of these can be argued as the moment a reasonable owner would have started asking questions.

Trust in a partner or other fiduciary counts for something, and plaintiffs often argue that it delays the duty to investigate. But the California Supreme Court has held that even a plaintiff dealing with a fiduciary must investigate once aware of facts that would make a reasonably prudent person suspicious. I would not build a case on the assumption that trust alone excuses years of silence.

What a late complaint must plead

A plaintiff who sues more than three years after the fraud cannot simply allege a recent discovery.

Where the complaint shows on its face that the claim would otherwise be barred, the plaintiff must specifically plead two things: the time and manner of discovery, and the inability to have made earlier discovery despite reasonable diligence. The burden is on the plaintiff to show diligence, and conclusory allegations will not survive a demurrer. That is the pleading rule the Supreme Court applied in Fox.

That is why I build the discovery timeline before drafting anything else. What did you receive each year? Who prepared it? What would you have had to do to find the problem, and why would a reasonable owner not have done it? If those answers are weak, the case is weak, whatever the merits of the fraud.

The same facts, different clocks

A fraud complaint rarely contains only a fraud claim, and each claim keeps its own time.

Breach of fiduciary duty generally falls under the four-year catch-all. (Code Civ. Proc., § 343.) If the gravamen of the claim is actual or constructive fraud, the three-year fraud period applies no matter how the claim is labeled. (Thomson v. Canyon (2011) 198 Cal.App.4th 594, 606-607.)
Breach of a written contract is four years. (Code Civ. Proc., § 337, subd. (a).) An oral contract is two. (Code Civ. Proc., § 339, subd. 1.) These periods usually run from the breach, not its discovery, as our page on the contract statute of limitations explains.
An action based on rescission of a written contract is four years, running from discovery where the ground is fraud. (Code Civ. Proc., § 337, subd. (c).)
Statutory claims by investors have a separate limit, covered on our investor fraud page.
Statutes that award multiple damages can draw a different clock. Courts have applied the one-year period for statutory penalties to some mandatory treble-damages claims. (Code Civ. Proc., § 340, subd. (a).) For a Penal Code 496 claim, where we pursue the civil remedy only, plan for the shortest plausible deadline.

Our overview of business lawsuit statutes of limitations lists the rest.

Extending or stopping the clock

Filing the complaint stops the clock. Short of that, the parties can agree to pause it.

California allows a written waiver of the limitations defense, signed by the person obligated. A waiver signed before the deadline can run no more than four years past it. One signed afterward lasts no more than four years from signing. Either can be renewed. (Code Civ. Proc., § 360.5.) These are usually called tolling agreements, and our page on tolling agreements covers how to draft one. They are common when former partners are negotiating and neither wants to file first.

A defendant's own conduct can also matter. Where the wrongdoer fraudulently concealed the claim, the period can be tolled, but only until a diligent plaintiff should have discovered it. That argument is fact-heavy and should be a backup, not a plan.

If you are defending an old fraud claim

The statute of limitations is your defense to raise. Raise it early.

Look first at the complaint. Suppose the dates show the claim is more than three years old and the plaintiff has not pleaded when and how the fraud was discovered. A demurrer may end the claim, or force an amendment that commits the plaintiff to specific facts.

Then collect what the plaintiff received and when: financial statements, tax returns, board packets, emails raising concerns, earlier demand letters. A single message in which the plaintiff voiced suspicion can fix the accrual date.

Be careful with requests to "preserve everyone's rights" in writing. A signed waiver can be enforced, and signing one gives up a defense that may be worth more than the settlement on offer.

Frequently asked questions

I just found out my former partner falsified the books five years ago. Is it too late to sue for fraud in California?

Probably not, if you truly had no earlier reason to suspect it. California's three-year fraud period runs from discovery of the facts, not from the date of the fraud. You will need to explain specifically when and how you found out and why reasonable diligence would not have uncovered it sooner. Other claims on the same facts may already be barred.

What is the statute of limitations for fraud in California?

Three years. Code of Civil Procedure section 338, subdivision (d), applies to actions for relief on the ground of fraud or mistake, and it provides that the claim does not accrue until the aggrieved party discovers the facts constituting the fraud. In practice the period begins when the plaintiff knew or reasonably should have suspected the wrongdoing.

What is the discovery rule for fraud?

It is the rule that delays the start of the limitations period until the plaintiff discovers, or has reason to discover, the claim. In California a plaintiff has reason to discover once there is reason to suspect wrongdoing. After that the plaintiff is expected to investigate and is treated as knowing what a reasonable investigation would have shown.

I suspected something was wrong years ago but only got proof last month. When did my three years start?

Most likely when the suspicion arose. California courts start the fraud limitations period at inquiry notice, which is reason to suspect a factual basis for the claim, not possession of proof. If you investigated diligently at the time and the facts could not reasonably be found, the start date may be later. The details of what you knew will decide it.

Is the deadline for breach of fiduciary duty different from fraud?

Usually. California applies the four-year catch-all period in Code of Civil Procedure section 343 to breach of fiduciary duty. Courts look past the label, though. If the heart of the claim is that the fiduciary deceived you, the three-year fraud statute applies instead, with its discovery rule.
