Slander is spoken defamation; libel is defamation fixed in a durable medium like writing, print, or a recording. That’s the textbook answer to slander vs. libel, and it’s accurate, but the distinction matters less in daily life than it used to. Almost everything people communicate now — texts, emails, social media posts, reviews, voicemails — is recorded, so most modern defamation disputes are libel disputes. What actually decides whether you have a case, or whether you’re exposed to one, is whether someone made a provably false statement of fact, shared it with another person, and caused real harm to your reputation.
The Core Difference
Slander covers statements that disappear the moment they’re made. A false accusation at a dinner party, a lie whispered in a hallway, a defamatory remark on a live phone call. Nothing fixes the words in place. The audience is whoever happened to be within earshot, and the only evidence afterward is memory.
Libel covers defamatory statements captured in a durable format: newspaper articles, books, photographs, emails, text messages, online reviews, social media posts. The defining feature is permanence. The statement can be read, forwarded, screenshotted, and archived indefinitely. Its potential audience is effectively unlimited, and its capacity to keep damaging someone’s reputation is far greater than a fleeting remark.
So the format question is really a permanence question. If the words still exist somewhere a stranger could find them tomorrow, you’re in libel territory. If they vanished into the air, you’re in slander territory.
Where Online Speech Fits
If you’re wondering whether a defamatory tweet, Facebook post, or Yelp review counts as slander or libel, it’s almost always libel. Courts generally treat social media content as libel because the text is typed, published, and stored in a retrievable format, even when the tone feels conversational. The same reasoning covers emails, text messages, voicemails (which are recorded), and comments posted on websites.
That classification usually helps the person suing. Social media posts can be shared, screenshotted, and indexed by search engines, so the reach of a defamatory post dwarfs what a spoken remark could manage. A single false review or viral post can trail someone for years, surfacing every time an employer, client, or anyone else searches their name.
One boundary worth knowing before you start drafting a lawsuit: federal law shields online platforms from liability for what their users post. Under Section 230 of the Communications Decency Act, “no provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider.”1Office of the Law Revision Counsel. 47 USC 230 – Protection for Private Blocking and Screening of Offensive Material If someone defames you in a Facebook comment, your claim runs against the person who typed it, not against Facebook.
Why the Distinction Actually Matters: Damages
The real bite of the slander/libel line shows up in what you have to prove. Under traditional common law, a libel plaintiff could recover general damages — compensation for reputational harm — without having to put a dollar figure on the loss. A slander plaintiff generally had to prove “special damages,” meaning concrete economic losses like a lost job or a canceled contract, unless the statement fell into one of the per se categories below.
General damages compensate for reputational harm and personal distress. Courts presume these flow from certain kinds of defamatory statements, particularly libel and defamation per se. You don’t produce a receipt showing what your reputation was worth before and after. The jury weighs the severity of the falsehood, how widely it spread, and the effect on your standing, then sets a figure.
Special damages are different. They’re proven economic losses: a job you lost, a contract that collapsed, clients who dropped you, revenue that disappeared. They require documentation, pay stubs, invoices, correspondence showing the line between the false statement and the financial hit. In most slander cases that don’t qualify as per se, this is the only damages path, and failing to prove them sinks the case. That’s the single biggest reason slander claims are harder to bring than libel claims.
Defamation Per Se: When the Damages Burden Disappears
Some false statements are considered so inherently damaging that courts presume harm without requiring proof of a specific financial loss. That doctrine — defamation per se — effectively erases the special damages hurdle for both slander and libel. Four traditional categories qualify:
- Falsely accusing someone of a serious crime.
- Falsely claiming someone has a loathsome, communicable disease that would cause others to avoid them.
- Falsely attacking someone’s competence, honesty, or integrity in their business, trade, or profession.
- Falsely accusing someone of serious sexual misconduct.
The professional category is the one that comes up most in practice, especially in workplace disputes. Telling a colleague’s clients that the colleague committed fraud, when that’s false, would likely qualify. The loathsome disease category has shrunk considerably as social attitudes have shifted, but it’s still on the books. When a statement fits any of these categories, the plaintiff can recover general damages without tracing specific lost dollars back to the statement.
What Every Defamation Claim Requires
Whether the claim is for slander or libel, the underlying elements are the same. The Restatement (Second) of Torts § 558 sets out four:
- A false and defamatory statement. True statements, however embarrassing, are not defamation.
- Publication to a third party. The statement has to reach at least one person other than the target. An insult delivered only to the person it’s about is just an insult.
- Fault. The speaker must have been at least negligent about the truth. How much more than negligent depends on who the plaintiff is.
- Damages. Either presumed (libel and per se) or proven financial loss (most slander).
The “statement of fact” part catches a lot of would-be claims. If a reasonable reader or listener would hear the remark as subjective opinion rather than a verifiable fact, it generally isn’t actionable. The Supreme Court addressed this in Milkovich v. Lorain Journal Co., holding that there is no blanket “opinion privilege” under the First Amendment, but a statement must imply provable facts to be actionable.2Legal Information Institute. Milkovich v. Lorain Journal Co., 497 US 1 (1990) “I think that contractor does shoddy work” leans toward opinion. “That contractor used substandard materials on the Johnson project” asserts a verifiable fact and could support a claim if false.
Public Figures Face a Much Higher Bar
Not everyone sues from the same starting line. The First Amendment imposes different fault requirements depending on who the plaintiff is, and that difference often decides whether a case is winnable.
In New York Times Co. v. Sullivan, the Supreme Court held that a public official can’t recover damages for a defamatory falsehood about their official conduct unless they prove “actual malice” — that the statement “was made with knowledge of its falsity or with reckless disregard of whether it was true or false.”3Justia. New York Times Co. v. Sullivan, 376 US 254 (1964) The standard was later extended to public figures generally: celebrities, prominent business leaders, and people who voluntarily step into a public controversy.
Actual malice is brutally hard to meet. Carelessness isn’t enough. The plaintiff has to show the defendant either knew the statement was false or seriously doubted its truth and published anyway. Most defamation claims by public figures die at this stage, which is exactly what the Court intended — the goal was to keep lawsuit anxiety from chilling public debate.4United States Courts. New York Times v. Sullivan
Private individuals have a lower bar. In Gertz v. Robert Welch, Inc., the Supreme Court held that states may set their own fault standards for private-figure plaintiffs but must require at least negligence.5Legal Information Institute. Gertz v. Robert Welch, Inc., 418 US 323 (1974) Negligence means the defendant didn’t take reasonable care to check the truth before speaking. If a neighbor spreads a false rumor about you, you likely only need to show they didn’t bother to verify it. If a newspaper runs a false story about a senator, the senator has to prove the paper knew it was false or recklessly ignored the truth.
Defenses That End Most Claims
Knowing the defenses matters as much as knowing the elements, whether you’re thinking of filing or worried about being sued.
Truth
Truth is an absolute defense. If the statement is substantially true, the claim fails regardless of how damaging or mean-spirited it was. “Substantially true” means the gist is accurate; minor errors in irrelevant details won’t rescue a claim when the core accusation checks out. Truth kills more defamation claims than any other defense, and it’s the first thing any attorney evaluates.
Opinion
Pure opinion is protected by the First Amendment, but the protection is narrower than people assume. A statement framed as opinion can still be actionable if it implies specific, verifiable facts. Prefacing an accusation with “I think” doesn’t launder it into an opinion when the sentence that follows asserts something provably true or false.2Legal Information Institute. Milkovich v. Lorain Journal Co., 497 US 1 (1990)
Absolute Privilege
Certain settings carry complete immunity, regardless of whether the statement was false or malicious. Statements by judges, lawyers, parties, and witnesses during judicial proceedings are absolutely privileged. The same protection extends to lawmakers during legislative proceedings and to certain official government communications. Courts and legislatures can’t function if every word risks a lawsuit.
Qualified Privilege
Qualified privilege protects good-faith statements made on a matter of shared interest. The classic example is an employer reference. A former employer who honestly tells a prospective employer that a candidate was fired for poor performance is generally protected, even if the assessment turns out to be wrong, as long as it wasn’t driven by malice. The privilege can be lost through ill will, by going beyond the scope of the occasion, or by sharing the information with people who had no legitimate reason to hear it.
Section 230
Section 230 of the Communications Decency Act generally bars defamation claims against online platforms for user-posted content.1Office of the Law Revision Counsel. 47 USC 230 – Protection for Private Blocking and Screening of Offensive Material Social media companies, review sites, and forums fall within it. The author of the content does not.
Deadlines Are Short
Every state imposes a filing deadline for defamation, and the windows are short compared to most civil claims. Statutes of limitations range from one to three years depending on the state. Miss the deadline and the claim is gone no matter how strong it was.
For online content, the “single publication rule” determines when the clock starts. The limitations period begins when the defamatory material is first published, not each time a new reader stumbles on it. A blog post from January 2024 starts the clock in January 2024, even if someone finds it in 2026. That prevents indefinite liability for archived content, and it also means you can lose the right to sue before you ever discover the material.
Retractions
Many states require a defamation plaintiff to request a retraction before filing suit, particularly for claims involving media outlets. A timely, prominent correction can significantly reduce the damages available, and in some states eliminates everything except proven financial losses. A buried or halfhearted retraction carries far less weight.
Even where retraction isn’t legally required, asking for one is useful. It creates a record showing the publisher was put on notice that the statement was false. A refusal to correct can be used later as evidence of fault or malice. A prompt, genuine retraction cuts the other way, making punitive damages much harder to recover.
