Defamation and Online Harassment Laws in Kansas

In Kansas, defamation is mainly a civil claim under common law. You must show a false and defamatory statement that was communicated to someone else and actually harmed your reputation, and a lawsuit generally has to be filed within one year of publication. Kansas has abolished defamation per se, so reputational harm is never presumed; the state also has an anti-SLAPP law, and knowingly false defamatory statements can be prosecuted as a misdemeanor.

01Defamation law in Kansas

Where the law comes from

Defamation in Kansas is a common law tort shaped by the courts, and a single tort covers both libel (written) and slander (spoken). A plaintiff must prove false and defamatory words, communicated to a third person, that harmed the plaintiff's reputation.

Is defamation a crime?

Kansas has a criminal statute called criminal false communication. It covers telling anyone information you know is false that tends to expose a living person to public hatred, contempt or ridicule, or to degrade the memory of someone who has died, and it is a class A nonperson misdemeanor; truth is a defense. Federal courts rejected constitutional challenges to the earlier version of this law in 1995 and 2005, reading it to require actual malice (in 1995, for statements on matters of public concern).

Statute of limitations

A lawsuit for libel or slander must be brought within one year. Courts applying Kansas law have generally started the clock when the statement is published or spoken, not when the person learns of it, although one older federal decision involving a credit report started it at discovery.

Defamation per se

Kansas has abolished defamation per se and presumed damages in all cases, which the Kansas Supreme Court acknowledged puts the state in the minority. Even a statement accusing someone of a crime or attacking their fitness for their profession requires evidence of actual harm to reputation, and without that harm no other damages can be recovered. The court confirmed this in 2023 in a case about negative online reviews of a surgeon.

Anti-SLAPP protection

The Public Speech Protection Act, enacted in 2016, lets a person sued over speech, petitioning or association on a public issue file a motion to strike, normally within 60 days of service of the most recent complaint. If the defendant makes that initial showing, the plaintiff must present substantial competent evidence of a prima facie case; discovery is generally paused, a defendant who wins recovers attorney fees and costs, and a denial can be appealed right away. Some claims are excluded, such as many claims against businesses over statements made to sell their goods or services.

Defenses and public figures

Truth is an absolute defense, judged as of the time the statement was published. Kansas also recognizes qualified privileges, including one for good-faith news reporting based on official information, which a plaintiff must overcome with proof of fault such as actual malice. Under the First Amendment, public officials suing over statements about their official conduct must prove actual malice, meaning knowledge of falsity or reckless disregard for the truth.

02Online harassment, cyberstalking and doxxing in Kansas

Cyberstalking

Kansas's stalking law covers a course of conduct of two or more acts aimed at a specific person that places them in fear for their own or their family's safety, and any act of communication, including electronic messages sent by computer, can be part of that conduct. A first offense is usually a class A person misdemeanor; repeat offenses, violations of a protective order and conduct aimed at a child under 14 are felonies.

Source9K.S.A. 21-5427

Online harassment

Harassment by telecommunication device makes it a crime to use a phone or other electronic communication device to send comments, images or text with intent to abuse, threaten or harass the recipient, or to knowingly send obscene or indecent content. It is a class A nonperson misdemeanor.

Source10K.S.A. 21-6206

Doxxing

Kansas makes it a crime to knowingly make a judge's or a judge's immediate family member's personal information available, such as a home address, personal phone number, personal email or photos, when sharing it poses an imminent and serious threat to their safety. This is a class A person misdemeanor, or a felony on a repeat conviction. For other people, doxxing may fall under the stalking or harassment laws when the conduct meets their elements.

Intimate images shared without consent

Breach of privacy includes sharing a nude or sexual image of an identifiable adult who had a reasonable expectation of privacy, without consent and with intent to harass, threaten or intimidate them. It also covers images created or altered by artificial intelligence or other digital means to depict the person. This is a felony, and online services are not liable under this law for content that other people post.

03How to remove defamatory content in Kansas

How to remove defamatory content in Kansas

A lawsuit is one route, but it is slow, costly and public. Much harmful content can come down sooner through the platform’s own reporting process, a legal notice to the site owner or host, or a removal request to search engines. The right route depends on where the content lives and on the law that applies to it.

Media Removal reviews each case and recommends the fastest route that fits it. Removal always depends on each platform and, where relevant, the courts.

04Frequently asked questions about defamation in Kansas

How long do you have to sue for defamation in Kansas?

Libel and slander claims in Kansas must be filed within one year. Courts have generally started that clock when the statement is published, not when you find out about it, so it is wise to act quickly.

Is defamation a crime in Kansas?

It can be. Kansas's criminal false communication statute makes it a class A nonperson misdemeanor to communicate information you know is false that tends to expose a living person to public hatred, contempt or ridicule, and truth is a defense. Most defamation disputes, however, are handled as civil lawsuits.

Do you have to prove damages for defamation in Kansas?

Yes. Kansas abolished defamation per se, so harm to your reputation is never presumed. You need evidence of actual reputational harm, such as declining revenue or fewer professional opportunities, before any damages can be awarded.

Can you sue over a fake online review in Kansas?

A false online review can support a defamation claim, but you must show it actually harmed your reputation, which the Kansas Supreme Court found missing in a 2023 case about negative reviews of a surgeon. Because the anti-SLAPP law treats goods and services in the marketplace as a public issue, the reviewer may also be able to ask the court to strike the claim early.

Does Kansas have an anti-SLAPP law?

Yes. The Public Speech Protection Act lets people sued over speech on public issues ask the court to strike the claim early. Discovery is generally paused while the motion is pending, and defendants who win the motion recover attorney fees and costs.
