What is defamation of character?

What defamation of character means

The phrase is not a separate legal claim. Courts and statutes say defamation, and split it into two branches: libel for statements in fixed form, slander for spoken ones. That split is covered on libel vs slander. Everything below applies to both.

Cornell Law's definition of defamation states the core of it in a sentence and is worth reading before any summary, including this one. The claim protects reputation, which means it protects the accuracy of what other people believe about you. It does not protect you from being disliked, criticised, or accurately described.

The four elements of a defamation of character claim

Element	What it means	Where claims usually fail
A false statement of fact	Something capable of being proved true or false, that is in fact false	The statement turns out to be opinion, or substantially true
Publication	Communicated to at least one person other than the claimant	Nobody else saw or heard it
Fault	Negligence, or actual malice if the claimant is a public figure	The speaker had reasonable grounds to believe it
Harm	Reputational or financial damage traceable to the statement	No provable loss, and no per se category applies

Some states add or phrase these differently, and a real claim also has to be filed inside a limitation period that is short for defamation, commonly one to three years depending on the state.

False statement of fact is the hard part

A statement is only actionable if it asserts something that could be checked. "This contractor took a deposit and never returned" is a factual assertion. "This contractor is the worst in town" is not, because there is no test that would prove it false.

Two related doctrines matter here. The statement has to be of and concerning the claimant, meaning a reader would understand it to be about that specific person. And it has to be materially false: under the substantial truth doctrine, a statement with small inaccuracies is still treated as true if its gist is accurate. A report that says you were charged with three offences when it was two does not usually become defamatory because of the count.

The fault standard depends on who you are

This is where American defamation law diverges most sharply from other countries. A public official or a public figure has to prove actual malice, the standard set in New York Times Co. v. Sullivan and explained in the First Amendment Encyclopedia's account of the actual malice standard set in New York Times Co. v. Sullivan. A private individual generally has to prove only that the speaker was negligent, though a later Supreme Court decision limits presumed and punitive damages for private claimants unless actual malice is shown.

There is also a middle category. A person can become a limited purpose public figure by entering a particular public controversy, which raises their burden for statements about that controversy only. A business owner who campaigns publicly on a local issue can end up in this position without ever intending to.

Damages, and the per se shortcut

Most claimants have to show actual harm: lost work, lost customers, a withdrawn offer, treatment for the effect on them. Certain categories, historically called defamation per se, allow damage to be presumed because the accusation is so obviously injurious: imputing a serious crime, a loathsome disease, sexual misconduct, or conduct incompatible with a person's trade or profession. The constitutional limits on presumed damages still apply, so per se is a shortcut rather than a bypass.

The opinion defence, and the others

There is a widespread belief that labelling something an opinion makes it safe. That is not the law. In Milkovich v. Lorain Journal the Supreme Court declined to recognise a separate constitutional privilege for opinion and held instead that the question is whether a statement implies an assertion of objective fact that can be proved false. "In my opinion, Jones perjured himself" implies a checkable fact and is not protected by its opening words.

The defences that do work are these:

• Truth. Complete, in every state. A true statement is never defamatory, however damaging.
• Genuine opinion. Protected where it implies no provably false fact. Reviews of taste, quality and experience usually sit here.
• Privilege. Absolute for statements made in court and legislative proceedings. Qualified in other settings, such as certain employer references, unless abused.
• Fair report. An accurate account of an official proceeding or public record is protected even if the underlying allegation is false.
• Anti-SLAPP. Most states now have a statute allowing early dismissal of a claim aimed at protected speech, often with the claimant paying the other side's legal fees.

What is not defamation of character

• A truthful statement, no matter how much damage it causes.
• An insult with no factual content.
• A negative review that expresses a genuine opinion about a service.
• An accurate report of a court record or an official proceeding.
• Criticism of a company's product, which is a separate tort called trade libel or product disparagement rather than personal defamation.

People also ask whether damaging a reputation is illegal. In almost every case it is a civil wrong rather than a crime. A small number of states retain criminal defamation statutes, and they are rarely enforced. That question is covered further on is it illegal to damage someone's reputation.

What to do about a statement you think is defamatory

Preserve it before anything else, with the URL and the date. Separate the factual assertions from the opinion. Then check the faster door: Google's process for reporting an inappropriate review handles policy violations without any legal theory, and most platforms have an equivalent. If the statement is a false assertion of fact and the harm is real, speak to a defamation lawyer in your state, and read what is online defamation and how to prove online defamation first so you arrive with the right question.

Nothing here is legal advice. The statute, the case law and the agency guidance are linked above so you can read the primary sources yourself. Sorting which parts of your situation are legal and which are simply search results is most of the work, and it is the first thing a reputation audit establishes.
