New Hampshire Defamation Laws: Libel & Slander (2026)

In New Hampshire, defamation is a civil claim for a false statement of fact that harms your reputation, and you have three years to sue under RSA 508:4. New Hampshire stands out because it has no general anti-SLAPP statute and prohibits punitive damages by law, two features that shape how a defamation case is fought and what it is worth.

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

What counts as defamation in New Hampshire?

Defamation in New Hampshire is a false statement of fact, published to a third party, that is of and concerning the plaintiff and tends to lower the plaintiff in the estimation of the community. New Hampshire courts have generally required a false and defamatory statement about the plaintiff, an unprivileged communication to a third person, and fault amounting at least to negligence. Publication to someone other than the plaintiff is essential, and in Independent Mechanical Contractors, Inc. v. Gordon T. Burke & Sons, Inc., 138 N.H. 110 (1993), the absence of any third-party recipient defeated the claim. Truth is a complete defense, because a substantially true statement cannot be defamatory. Pure opinion that cannot be proven true or false is protected, a point the New Hampshire Supreme Court applied when it held that calling a company a patent troll was non-actionable opinion in Automated Transactions, LLC v. American Bankers Association (2019). The statement must be one a reasonable reader or listener would take as a factual assertion about the plaintiff.

Libel vs slander in New Hampshire

New Hampshire recognizes both libel and slander, and RSA 508:4 sets the same three-year deadline for each. Libel is defamation in a fixed or permanent form, such as a newspaper article, a letter, an email, a social media post, or a broadcast script. Slander is spoken defamation that exists only at the moment it is uttered. The distinction historically affected damages, because slander outside the recognized per se categories generally required proof of special damages while libel did not. That division still matters in New Hampshire, because the state recognizes defamation per se with presumed damages, so whether a statement is libel or slander and whether it fits a per se category together shape what the plaintiff must prove. Internet defamation, including a false online review or a defamatory social media post, is treated as libel because the statement exists in a fixed, lasting form.

Defamation per se in New Hampshire

New Hampshire recognizes defamation per se, statements so inherently damaging that the law presumes injury without proof of specific monetary loss. The traditional categories are statements that falsely charge a crime, impute a loathsome or infectious disease, or tend to injure a person in their trade, business, or profession, with imputing unchastity as the historical fourth category. When a statement is defamatory per se, general damages may be presumed. When it is not, the plaintiff must plead and prove special damages, meaning actual, quantifiable economic harm. The category a statement falls into therefore drives the entire case, because it decides whether the plaintiff can recover without itemizing a dollar loss.

Watch out: Not every harsh statement is per se. If the words do not clearly fit a recognized category, New Hampshire requires proof of special damages, which is much harder to establish than presumed harm.

The statute of limitations to sue for defamation in New Hampshire

The statute of limitations for defamation in New Hampshire is three years, set by RSA 508:4, the state's general personal-action statute. That statute applies a discovery rule to most personal actions, but it expressly excepts slander and libel, so a defamation cause of action runs from the date the statement is published rather than from when the plaintiff discovers it. Plaintiffs therefore cannot count on a delayed start to the clock. It is worth noting historically that New Hampshire once allowed a six-year window for libel, which is why the United States Supreme Court heard Keeton v. Hustler Magazine, Inc., 465 U.S. 770 (1984), a case filed in New Hampshire because it was the only state where the claim was not time-barred. The current period is three years. The single-publication rule, under which one edition or posting counts as a single publication rather than a fresh one each time it is read, has not been squarely adopted by the New Hampshire Supreme Court. The Keeton opinion discussed the rule but reserved the question, saying its actual applicability "is a matter of substantive law, not personal jurisdiction." Plan on the three-year clock running from first publication, and ask a New Hampshire attorney how it applies to a statement that stays online.

Watch out: Because RSA 508:4 excepts libel and slander from the discovery rule, the three-year clock runs from publication. Waiting to sue until you learn of the statement does not reliably extend your deadline.

New Hampshire's anti-SLAPP law

New Hampshire does not have a general anti-SLAPP statute, which puts it in a minority of states with no such law. Anti-SLAPP laws, where they exist, let a defendant who is sued over protected speech file an early motion to dismiss, pause discovery, and often recover attorney fees if the suit is thrown out. New Hampshire tried to create such a procedure, but in Opinion of the Justices (SLAPP Suit Procedure), 138 N.H. 445 (1994), the New Hampshire Supreme Court advised that the proposed special-motion mechanism was unconstitutional because it would let a court resolve disputed facts on the pleadings and affidavits, infringing the state constitutional right to a jury trial. As a result, a defendant facing a defamation suit in New Hampshire must defend the case through the ordinary litigation process, using motions to dismiss and motions for summary judgment rather than a dedicated speech-protective procedure. Defendants still keep their core defenses, including truth, opinion, and privilege, along with the constitutional actual-malice protections for speech about public figures, and a court may impose sanctions for frivolous filings.

Public figures and actual malice

The plaintiff's status as a public or private figure sets the fault standard, and this is federal constitutional law that applies the same way in New Hampshire. 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 defendant published with knowledge that the statement was false or with 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, people who have achieved general fame or who have voluntarily entered a particular public controversy. Private individuals receive more protection. New Hampshire courts generally require a private plaintiff to prove only that the defendant was at least negligent regarding the truth of the statement, a lower bar than actual malice. Because the fault standard can decide the outcome, whether the plaintiff is a public or private figure is often the pivotal question in a New Hampshire defamation case.

Damages you can recover in New Hampshire

Damages in a New Hampshire defamation case fall into a few categories, with one notable limit. Special damages are specific, provable economic losses, such as lost income, lost clients, or lost contracts, and they must be pleaded and proven when the statement is not defamatory per se. General or presumed damages compensate for harm to reputation and emotional distress and may be presumed in defamation per se cases without proof of a precise dollar figure. New Hampshire is distinctive because RSA 507:16 prohibits punitive damages in any action unless another statute provides otherwise. Instead, New Hampshire allows enhanced compensatory damages, which let a jury award liberal compensatory damages when the defendant's conduct was wanton, malicious, or oppressive, but these are still compensatory in nature rather than a separate punitive award. Because the availability of presumed damages depends on the per se analysis, the category of the statement drives both liability and the size of any recovery.

How to sue for defamation in New Hampshire

Filing a defamation suit in New Hampshire generally follows a sequence, though every situation differs and this is general information, not legal advice. A common first step is a cease-and-desist or retraction demand letter that identifies the false statement, explains why it is false, and asks for removal or correction, even though New Hampshire has no statute that rewards a retraction. Preserving evidence is critical: save the statement, the publication date, the URLs, screenshots, and the names of anyone who saw or heard it, because that proof supports the publication element and any special damages. The plaintiff then files a civil complaint in the appropriate New Hampshire superior court before the three-year deadline in RSA 508:4 expires, naming the speaker or publisher and stating the false statements, the harm, and the basis for the court's jurisdiction. Because New Hampshire has no anti-SLAPP statute to weed out weak suits early and bars punitive damages, many plaintiffs and defendants consult a licensed New Hampshire attorney early to evaluate whether the statement is a provable false fact and what the realistic recovery looks like.

How to Sue for Defamation of Character in New Hampshire

To sue for defamation of character in New Hampshire, a plaintiff generally must file within three years of when the cause of action accrued, under RSA 508:4, which sets a three-year limit for personal actions including slander and libel. Most defamation cases are filed in the New Hampshire Superior Court; a smaller claim may be brought in the Circuit Court's small-claims division, which handles disputes up to $10,000. The elements you must prove, and the defenses the speaker can raise, track the same national rules: a false statement of fact about you, communicated to a third party, made with at least negligence, that damages your reputation.

• Statute of limitations: 3 years (RSA 508:4)
• Where to file: New Hampshire Superior Court (Circuit Court small claims for disputes up to $10,000)
• Damages: No statutory cap on compensatory defamation damages
• Anti-SLAPP: None. New Hampshire has no general anti-SLAPP statute, so a defendant facing a weak speech-based suit cannot use a special early-dismissal motion and must defend through the ordinary litigation process.

Is defamation a crime in New Hampshire? Yes. RSA 644:11 makes it a class B misdemeanor to purposely communicate information you know to be false and know will tend to expose another living person to public hatred, contempt, or ridicule. The statute is still in force. In Frese v. Formella, No. 21-1068 (1st Cir. Nov. 8, 2022), the First Circuit affirmed the dismissal of a constitutional challenge to it, holding that Garrison v. Louisiana forecloses the First Amendment attack and that the statute is not unconstitutionally vague. Prosecutions are uncommon, and the court noted that criminal defamation is rarely prosecuted in New Hampshire, but they do happen: the plaintiff in that case had twice been charged under section 644:11. Most defamation disputes are still resolved through civil lawsuits.
