California Defamation Laws: Libel & Slander (2026)

In California, defamation is a civil claim divided into libel (written) and slander (spoken), and you generally have one year to sue from the date the statement was first published, under Code of Civil Procedure section 340(c). California also has one of the strongest anti-SLAPP statutes in the country.

This guide is part of our Defamation Laws by State series. For the underlying concept, see what defamation of character means.

What counts as defamation in California?

Defamation in California is a false statement of fact, published to at least one third party, that is of and concerning the plaintiff and causes reputational harm. Civil Code sections 44 through 46 supply the framework: section 44 names the two forms, libel and slander, while sections 45 and 46 define each. A plaintiff must show the statement was false, unprivileged, communicated to someone other than the plaintiff, and made with the required level of fault. Private plaintiffs generally need to prove at least negligence as to falsity, and public plaintiffs must prove actual malice. Opinion that cannot be proven true or false is not actionable, and truth is a complete defense under California law. The statement must also be reasonably understood as referring to the plaintiff. Damages flow from the type of defamation and whether the statement qualifies as defamation per se under section 45a or 46.

Watch out: A statement framed as opinion can still be defamatory if it implies undisclosed false facts. California courts look at the full context, not just the label "in my opinion."

Libel vs slander in California

California separates defamation into libel and slander, and the distinction controls how damages are proven. Libel, under Civil Code section 45, is a false and unprivileged publication by writing, printing, picture, effigy, or other fixed representation to the eye that exposes a person to hatred, contempt, ridicule, or obloquy, or injures them in their occupation. Slander, under Civil Code section 46, is a false and unprivileged oral statement (or one communicated by radio or any mechanical means). Online posts, emails, and social media generally fall under libel because they are fixed. Under section 45a, libel that is defamatory on its face is libel per se and supports presumed damages, while libel requiring explanatory facts requires proof of special damages. Slander per se under section 46 likewise supports damages without proof of special harm.

Defamation per se in California

Defamation per se in California is a statement so inherently damaging that the law presumes injury without proof of actual loss. For slander, Civil Code section 46 lists four categories: charging a person with a crime or with having been indicted, convicted, or punished for one; imputing the present existence of an infectious, contagious, or loathsome disease; tending directly to injure the person in respect to their office, profession, trade, or business; and imputing impotence or a want of chastity. A fifth catch-all covers statements that by natural consequence cause actual damage. For written statements, libel per se under section 45a applies when the words are defamatory on their face without needing explanatory matter. When a statement is per se, the plaintiff need not plead or prove special damages to recover general damages. Statements that require extrinsic facts to be understood as defamatory are treated as per quod and require proof of special damages.

The statute of limitations to sue for defamation in California

The statute of limitations for libel and slander in California is one year, set by Code of Civil Procedure section 340(c). The clock generally starts when the statement is first published, not when the plaintiff happens to read it. California follows the single-publication rule under Civil Code section 3425.3, meaning a single edition of a newspaper, book, or broadcast (and, by extension, a single online posting) counts as one publication that triggers the one-year period once. Reposting the same content in the same form does not restart the clock, although a substantial modification aimed at a new audience can. In narrow circumstances involving concealed defamation, courts have applied a discovery rule that delays accrual until the plaintiff reasonably should have learned of the statement. Because one year is short, missing the deadline almost always bars the claim regardless of merit.

Watch out: The single-publication rule means an old online post that you discover years later may already be time-barred. The clock runs from the original posting, not your discovery.

California's anti-SLAPP law

California's anti-SLAPP statute, Code of Civil Procedure section 425.16, is among the strongest in the nation and is frequently used in defamation cases. It lets a defendant file a special motion to strike a claim that arises from an act in furtherance of the right of petition or free speech in connection with a public issue. The analysis has two steps: the defendant first shows the claim targets protected activity, then the burden shifts to the plaintiff to show a probability of prevailing on the merits. Filing the motion automatically stays discovery under section 425.16(g) until the court rules. If the defendant wins, section 425.16(c) makes an award of attorney fees and costs mandatory, which gives the statute real teeth. The law is to be construed broadly, and it covers speech on public issues such as reviews, reporting, and commentary on matters of public interest.

Public figures and actual malice

Whether a plaintiff is a public or private figure changes the fault standard, and this rule comes from federal constitutional law that applies the same way in every state. Under New York Times Co. v. Sullivan, 376 U.S. 254 (1964), a public official must prove the statement was made with actual malice, meaning knowledge that it was false or reckless disregard for whether it was true. Gertz v. Robert Welch, Inc., 418 U.S. 323 (1974) extended the actual-malice requirement to public figures and held that private plaintiffs need prove only fault (generally negligence) to recover actual damages, but must show actual malice to recover presumed or punitive damages on matters of public concern. California courts apply these standards directly. A person can be a general-purpose public figure or a limited-purpose public figure who has voluntarily entered a particular public controversy.

Damages you can recover in California

California recognizes special, general, and punitive damages in defamation cases, with availability tied to the type of statement and the plaintiff's status. Special damages are out-of-pocket economic losses, such as lost business or income, that the plaintiff must prove with specifics. General damages compensate for reputational harm, emotional distress, and similar injury; these are presumed when the statement is defamation per se under Civil Code sections 45a and 46, so the plaintiff need not itemize loss. Punitive damages may be available under Civil Code section 3294 where the plaintiff proves oppression, fraud, or malice by clear and convincing evidence. Civil Code section 48a limits recovery against newspapers, broadcasters, and similar media to special damages unless the plaintiff serves a written correction demand within 20 days of learning of the publication and the outlet fails to publish a correction. On matters of public concern, federal law requires actual malice before presumed or punitive damages are available.

How to sue for defamation in California

Suing for defamation in California generally follows a sequence, and the steps below describe the typical process rather than advice for any specific situation. First, plaintiffs often send a cease-and-desist or retraction demand; for media defendants, a written correction demand within 20 days is required under Civil Code section 48a to preserve general damages. Second, preserve evidence: capture the exact statement, the date and place it appeared, screenshots with URLs, and proof it reached a third party. Third, evaluate the one-year deadline under Code of Civil Procedure section 340(c) and the likelihood of an anti-SLAPP motion under section 425.16, which can shift fees against a losing plaintiff. Fourth, the complaint is filed in the appropriate California superior court, identifying the statement, its falsity, publication, and resulting harm. Because the deadlines are short and anti-SLAPP exposure is real, consulting a lawyer licensed in California is the prudent course.
