Washington Defamation Laws: Libel, Slander & Suing (2026)

In Washington, defamation is a civil claim for libel or slander with a two-year filing deadline under RCW 4.16.100. After its earlier anti-SLAPP law was struck down in Davis v. Cox, Washington adopted the Uniform Public Expression Protection Act at Chapter 4.105 RCW. Truth is a complete defense.

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

What counts as defamation in Washington?

Washington courts have generally required a defamation plaintiff to prove four elements: a false statement, an unprivileged communication of that statement to a third party, fault by the speaker, and damages. The statement must be one of fact that can be proven true or false, because pure opinion is constitutionally protected and is not actionable. Truth is an absolute defense in Washington, so a statement that is accurate cannot support a claim no matter how harmful it is. The statement must be of and concerning the plaintiff. Because RCW 4.16.100 imposes a two-year deadline, and because Washington applies the single-publication rule, identifying the false factual assertion and acting promptly are both important first steps. Washington courts also recognize that for matters of public concern, constitutional rules limit when reputational harm may simply be presumed rather than proven.

Watch out: An honest opinion or fair comment on disclosed facts is not defamation. Courts ask whether a reasonable reader would understand the words as a verifiable fact rather than a subjective view.

Libel vs slander in Washington

Washington recognizes the traditional split between libel and slander, but both are governed by the same two-year limitation period in RCW 4.16.100. Libel is written or recorded defamation and includes newspaper articles, broadcasts, websites, social media posts, and online reviews. Slander is spoken defamation, such as a defamatory remark made aloud at a meeting or in conversation. The elements are the same for both, but the damages rules historically differed. Some spoken statements required proof of special damages unless they fell within a per se category, while written defamation that was defamatory on its face allowed presumed damages, subject to the constitutional limits Washington courts apply to speech on matters of public concern. The same two-year filing window applies to both libel and slander.

Defamation per se in Washington

Defamation per se in Washington refers to statements so inherently damaging that the law may presume harm to reputation, so the plaintiff need not prove specific economic loss to recover. Washington courts recognize four categories: falsely imputing that a person committed a crime; imputing that a person has a loathsome or communicable disease; imputing sexual misconduct or unchastity; and statements that injure a person in their business, trade, profession, or office. When a statement fits a category, damages may be presumed. Washington applies an important constitutional limit, however: general damages may be presumed in a per se case only where the speech is not on a matter of public concern, or where the plaintiff proves actual malice. That restriction reflects the U.S. Supreme Court's decision in Gertz v. Robert Welch, Inc., and it means the per se shortcut does not always relieve a plaintiff of proving harm.

The statute of limitations to sue for defamation in Washington

The statute of limitations for defamation in Washington is two years. RCW 4.16.100(1) provides that an action for libel, slander, assault, assault and battery, or false imprisonment must be brought within two years. The clock generally begins to run on the date the defamatory statement is first published to a third party, or, under the discovery rule applied in some cases, when the plaintiff through reasonable diligence should have discovered it. Washington follows the single-publication rule adopted by its Supreme Court, which means that for a book, broadcast, or online post, the period runs from the date of first publication and does not restart each time someone reads, shares, or downloads the material. Substantively revising and republishing the content to reach a new audience can restart the period. Two years is a moderate deadline, but it still runs quickly, so preserving the statement and the publication date early is important.

Watch out: The two-year clock generally runs from first publication. Do not assume that an old post that resurfaces, or that you only just discovered, automatically resets the deadline.

Washington's anti-SLAPP law

Washington has an anti-SLAPP law, but its history is unusual. The state's first anti-SLAPP statute, RCW 4.24.525, was struck down by the Washington Supreme Court in Davis v. Cox, 183 Wn.2d 269 (2015), which held it violated the state constitutional right to a jury trial by requiring judges to weigh disputed facts and dismiss nonfrivolous claims. In 2021, Washington became the first state to enact the Uniform Public Expression Protection Act (UPEPA), now codified at Chapter 4.105 RCW, which was drafted to fix that defect. Under UPEPA, a defendant sued over the exercise of the rights of speech, press, assembly, petition, or association on a matter of public concern, or over a communication in or about a governmental proceeding, may file a special motion for expedited relief under RCW 4.105.020. Filing the motion stays most proceedings, including discovery, and a prevailing movant is generally entitled to court costs and reasonable attorney fees, which deters suits aimed at silencing public-interest speech.

Public figures and actual malice

The level of fault a Washington defamation plaintiff must prove turns on who they are, and that rule comes from federal constitutional law applied identically in every state. Under New York Times Co. v. Sullivan, 376 U.S. 254 (1964), a public official suing over statements about official conduct must prove actual malice, meaning the speaker knew the statement was false or acted with reckless disregard for its truth. Gertz v. Robert Welch, Inc., 418 U.S. 323 (1974), extended actual malice to public figures and held that private plaintiffs generally need only prove negligence, although they usually must show actual injury when the speech involves a matter of public concern. Actual malice must be proven by clear and convincing evidence, a higher standard than the usual preponderance. In Washington defamation litigation, whether the plaintiff is a public official, a public figure, or a private person is frequently the decisive issue, and it also controls when presumed damages are available.

Damages you can recover in Washington

A defamation plaintiff in Washington may recover several types of damages. Special damages cover concrete economic losses, such as lost wages, lost clients, or lost business directly caused by the defamatory statement. General damages compensate for reputational harm, mental anguish, and humiliation. In a defamation per se case, damages may be presumed, but only where the speech is not on a matter of public concern or where the plaintiff proves actual malice, reflecting the constitutional limit from Gertz. Washington does not generally allow punitive damages in defamation cases, because Washington does not permit punitive damages unless a statute expressly authorizes them, so plaintiffs typically recover only compensatory damages. The anti-SLAPP statute, Chapter 4.105 RCW, can end a claim early and shift fees where the suit targets public-interest speech, so a plaintiff should weigh that risk before filing.

How to sue for defamation in Washington

Pursuing a Washington defamation claim generally follows a sequence, though the right path depends on the facts. Many plaintiffs start by preserving evidence, including the exact statement, the publication date, and the audience, because the single-publication rule ties the deadline to first publication. A cease-and-desist or retraction demand can resolve some disputes early and creates a record of the objection. A plaintiff then files a complaint in the appropriate Washington superior court within the two-year period set by RCW 4.16.100. If the suit targets speech on a matter of public concern, the defendant may file a special motion for expedited relief under the UPEPA anti-SLAPP statute, Chapter 4.105 RCW, which stays discovery and can lead to early dismissal and a fee award, so plaintiffs should be ready to show the statement was a false assertion of fact rather than protected speech. Because of the anti-SLAPP risk and the fault standards, consulting a licensed Washington attorney early is wise. This article is general information, not legal advice.
