California Civil Code 1710: Deceit, Damages, and Defenses

California Civil Code Section 1710 defines “deceit” for purposes of a civil fraud claim, and it recognizes four separate kinds: intentional misrepresentation, negligent misrepresentation, concealment, and false promise.¹ It works alongside Section 1709, which makes anyone who willfully deceives another person into changing position to their detriment liable for the resulting harm.² Section 1709 supplies the liability rule; Section 1710 tells you what conduct counts.

The Four Kinds of Deceit

Each category targets a different kind of dishonesty, and each carries its own proof requirements. Figuring out which one fits your situation matters, because it changes what you have to show and what you can recover.

Intentional Misrepresentation

The first category is the classic lie: someone states a fact while knowing it is false.¹ A seller who tells you a car has never been in a wreck, knowing it was totaled and rebuilt, has committed intentional misrepresentation. The defining feature is the speaker’s own belief at the moment they spoke. This is the most serious form of deceit under the statute and the one that most readily supports punitive damages on top of ordinary compensation.

Negligent Misrepresentation

The second category catches people who make factual assertions with no reasonable basis for believing them.¹ The speaker may not have meant to lie, but they had no business making the claim. A real estate agent who assures you a house has no structural problems without ever looking, when a basic inspection would have shown foundation damage, fits here. You do not have to prove the person knew they were lying. You have to show they had no reasonable grounds for the statement. Because there is no intentional wrongdoing, recovery is generally limited to compensatory damages.

Concealment

The third category targets silence rather than speech. It applies when someone with a duty to share information deliberately withholds it, or shares some facts while omitting others in a way that misleads.¹ A home seller who mentions a recent renovation but hides that the work was done without permits is the textbook example.

Not every relationship carries a duty to speak up. California courts have recognized the duty in several situations: when someone makes partial statements that become misleading without the omitted facts, when the facts are accessible only to one party and that party knows the other side cannot reasonably discover them, and when someone actively prevents the other party from learning the truth.³ Fiduciary relationships, such as those involving trustees, financial advisors, and business partners, carry the broadest disclosure obligations.

False Promise

The fourth category covers a promise made with no intention of keeping it.¹ This is not about plans that later fall apart or promises broken because circumstances changed. The fraud lives in the promisor’s state of mind at the moment they made the promise. Someone who promises to deliver goods next month while already planning to take your deposit and disappear has made a false promise.

Proving it is notoriously hard. You need evidence of what someone was thinking, and people rarely announce that they intend not to perform. Courts look at circumstantial signals: whether the person had any ability to perform, whether they took any steps toward performance, whether they immediately did something inconsistent with what they had promised. A pattern of similar broken promises to other people can be powerful evidence too.

What a Plaintiff Has to Prove

Whichever category applies, a California fraud claim requires five elements: a false representation, concealment, or broken promise; the defendant’s knowledge that the statement was false, or a lack of reasonable grounds for believing it true; an intent that the plaintiff rely on it; the plaintiff’s actual and justifiable reliance; and resulting damage.⁴

Justifiable reliance is where plaintiffs most often stumble. If the false statement was obviously absurd, or if you had easy access to the truth and ignored it, a court may decide your reliance was not justified. California does not require you to have independently investigated every claim the other side made. The question is whether a reasonable person in your position, knowing what you knew, would have relied.

Pleading With Specificity

Fraud complaints face a stricter pleading standard than ordinary civil complaints. You have to identify who made the false statement, what they said, when and where they said it, and how it was communicated. Vague allegations that someone “acted fraudulently” will get the case dismissed at the door. When a company is the defendant, you typically need to name the specific person inside the organization who made or authorized the misrepresentation. Fraud is a serious accusation, and defendants are entitled to enough detail to defend against it.

What You Can Recover

California uses the “out-of-pocket” rule for fraud in property transactions. Damages are the difference between what you actually gave up and the actual value of what you received. That contrasts with the “benefit-of-the-bargain” measure used in many other states, which compares what you got against what the property was represented to be worth. California’s statute explicitly rejects the benefit-of-the-bargain measure.⁵

On top of the difference in value, you can recover other losses flowing from the fraud: money you reasonably spent in reliance on the false statements, lost use and enjoyment of property, and lost profits you would have earned had the property been what the other party claimed.⁵

Punitive Damages

When the fraud is intentional, California allows punitive damages meant to punish the wrongdoer and deter similar conduct. You have to prove by clear and convincing evidence that the defendant acted with oppression, fraud, or malice. In this context, “fraud” means intentional misrepresentation, deceit, or concealment of a material fact with intent to deprive someone of property, legal rights, or otherwise cause injury.⁶ That is a higher standard than the “preponderance” bar that applies to the underlying claim.

Undoing the Deal

Money is not always the right fix. California also allows equitable remedies. Rescission unwinds the contract entirely, returning both parties to where they started: you give back what you received, and the other side returns what they got from you. Restitution, a related remedy, forces the dishonest party to disgorge whatever benefit they gained from the fraud. These are useful when the fraud infected the whole transaction and you would rather walk away than try to quantify losses.

Common Defenses

Defendants have several ways to defeat or narrow a Section 1710 claim, and which ones work depends on the category of deceit alleged.

No intent to deceive. For intentional misrepresentation and false promise, the defendant can argue they genuinely believed the statement was true, or genuinely intended to perform the promise when it was made. Both categories hinge on state of mind, so honest belief defeats them.¹ This defense does nothing against a negligent misrepresentation claim, where intent is beside the point.

Puffery or opinion, not fact. A defendant can also argue that no reasonable person would treat the statement as a fact. Sales puffery and expressions of opinion generally cannot support a fraud claim. A used car dealer calling a vehicle “a great value” is offering an opinion. Telling you the odometer reading is accurate is stating a fact. Courts draw the line by asking whether the listener got a concrete assertion or a subjective judgment.

Statute of limitations. Fraud claims in California must be brought within three years, but the clock does not start when the fraud happens. It starts when you discover the fraud, or when a reasonably diligent person in your position would have discovered it.⁷ A defendant raising this defense has to show you either knew, or should have known, more than three years before filing.

How Section 1710 Fits With Related Statutes

Section 1710 does not stand alone. Section 1709 supplies the liability rule: anyone who willfully deceives another person into changing position to their detriment is liable for the resulting harm.² Section 1710 defines what “deceit” means for that rule.

Section 1572 covers similar ground but applies specifically to fraud in the making of a contract. It shares the same four categories and adds a fifth catch-all: “any other act fitted to deceive.”⁸ That broader language gives courts more room when a fraudster’s conduct does not fit neatly into the four named types. If the fraud induced you to enter a contract, Section 1572 may provide an additional or alternative basis for the claim.
