When someone tries to ruin your reputation by spreading false statements about you, the legal term is defamation. Written or published falsehoods are called libel; spoken ones are called slander. Both are civil wrongs, which means you can sue the person responsible and ask a court for money damages or an order to stop. Whether you actually have a case depends on what was said, how it was shared, who you are, and how much harm it caused.
Libel and Slander Are the Two Forms
The split between libel and slander matters more than most people expect. Written falsehoods persist. A defamatory blog post, social media comment, text message, or news article can circulate indefinitely and reach a far larger audience than something said in conversation. Courts have historically treated libel as inherently damaging, which can mean you don’t have to prove specific financial losses to recover.
Spoken falsehoods are harder to win on. Because spoken words are fleeting, courts in most jurisdictions require you to show “special damages” for slander, meaning specific money you lost as a direct result of what was said. The major exception is “slander per se,” covering spoken falsehoods so inherently harmful that the law presumes damage. The traditional per se categories include falsely accusing someone of a crime, a serious communicable disease, incompetence in their profession, or sexual misconduct.1Legal Information Institute (LII) / Cornell Law School.

What You Have to Prove
A defamation claim has four elements. You need a false statement presented as fact, not opinion. The statement must have been shared with at least one other person besides you. The speaker must have been at least careless about whether it was true. And the statement must have actually damaged your reputation.2LII / Legal Information Institute. Defamation
The fact-versus-opinion line is where most claims get complicated. “I think John is a terrible boss” is opinion and generally protected. “John was fired from his last job for stealing” when that never happened is a false statement of fact and potentially actionable. Courts look at the full context to decide whether a reasonable person would read the statement as asserting something verifiable or just venting a viewpoint. Vague insults and rhetorical hyperbole almost always land on the protected side.
Truth is a complete defense.2LII / Legal Information Institute. Defamation If what someone said about you is accurate, you have no defamation case regardless of how much damage it caused. And the burden of proving falsity sits with you, the person bringing the claim.
Public Figures Face a Much Higher Bar
How much fault you have to prove depends on whether a court treats you as a public figure or a private individual. Private individuals generally need to show only that the speaker was negligent, meaning they failed to use reasonable care in checking the truth. The Supreme Court held in Gertz v. Robert Welch, Inc. that states can set their own standard for private-figure claims as long as they require at least some showing of fault.3Legal Information Institute (LII) / Cornell Law School. Gertz v Robert Welch Inc
Public figures and public officials have a much steeper climb. Under the “actual malice” standard from New York Times Co. v. Sullivan, they must prove the speaker either knew the statement was false or made it with reckless disregard for the truth.4Legal Information Institute (LII) / Cornell Law School. New York Times v Sullivan 1964 That is an intentionally high bar. The reasoning is that public figures have voluntarily stepped into the spotlight and typically have access to media channels to answer false claims. The First Amendment weighs especially heavily when the speech concerns public affairs.5Legal Information Institute (LII) / Cornell Law School. First Amendment
There’s a middle category too. A “limited-purpose public figure” is someone otherwise private who voluntarily injects themselves into a specific public controversy to influence the outcome. A parent leading a high-profile campaign against a school board policy, for example, might be treated as a public figure for claims tied to that campaign while remaining a private figure for everything else.
When Harm Is Presumed: Defamation Per Se
Normally you have to prove specific, measurable harm. Defamation per se is the exception. When a false statement falls into certain inherently damaging categories, the law presumes you suffered harm and lets you recover without pinning down a dollar figure.1Legal Information Institute (LII) / Cornell Law School. Libel Per Se
The four traditional categories are:
- Falsely saying someone committed a crime.
- Falsely claiming someone has a serious infectious or “loathsome” disease.
- False statements that harm someone in their trade, business, or profession.
- Falsely accusing someone of being unchaste or engaging in sexual impropriety.
The professional category is the one that drives most modern cases. A false online review claiming a doctor lost their medical license, or a social media post alleging a contractor committed fraud, can qualify. Because these statements strike at someone’s ability to earn a living, courts treat the harm as self-evident.
Related Claims When Defamation Doesn’t Quite Fit
Defamation is the most common claim when someone attacks your reputation, but it’s not the only one.
False Light
A false light claim targets statements that place you in a misleading position a reasonable person would find highly offensive. The difference from defamation is subtle: defamation focuses on damage to your reputation in the eyes of others, while false light focuses on the emotional harm of being publicly misrepresented. A statement doesn’t have to be technically false to support a false light claim; it just has to create a seriously misleading impression. Not every state recognizes false light as a separate claim.
Intentional Infliction of Emotional Distress
When someone’s conduct goes beyond spreading falsehoods and crosses into truly outrageous behavior, you may have a claim for intentional infliction of emotional distress. The bar is deliberately high. The conduct must be so extreme that no reasonable person would consider it acceptable, and it must cause severe emotional suffering.6Legal Information Institute (LII) / Cornell Law School. Intentional Infliction of Emotional Distress A single rude comment almost never qualifies.
Business Disparagement
If the false statements target your business, products, or services rather than you personally, the claim is business disparagement, sometimes called trade libel. It requires you to prove actual financial losses, like lost sales or canceled contracts, caused by the false statement, and you generally need to show the speaker acted with malice or reckless disregard for the truth. Personal defamation protects your individual reputation; business disparagement protects your economic interests.
What the Other Side Will Argue
Before you file anything, know the defenses the other side will raise. They can end a case quickly.
Truth
Truth is absolute. If the statement is substantially true, the claim fails regardless of how much damage it did or how malicious the intent was.2LII / Legal Information Institute. Defamation The statement doesn’t need to be true in every minor detail; substantial truth is enough.
Opinion
Pure opinion is constitutionally protected. The complication is that people often package factual assertions as opinions. “In my opinion, that restaurant poisons its customers” contains an implied factual claim and could still be actionable. Courts look past the label and ask whether a reasonable person would understand the statement as implying verifiable facts.
Privilege
Some speakers are immune because of the setting in which they speak. Absolute privilege protects statements made by judges, attorneys, witnesses, and parties during judicial proceedings, and by legislators during legislative proceedings.7Legal Information Institute (LII) / Cornell Law School. Absolute Privilege That protection applies even if the statements are knowingly false. A fair reporting privilege also protects people who accurately summarize official proceedings or public records, even if the underlying statements being reported were defamatory.
Anti-SLAPP Laws
Anti-SLAPP statutes protect people from being sued simply for exercising free speech. A “SLAPP” is a Strategic Lawsuit Against Public Participation, filed primarily to silence a critic rather than to vindicate a legitimate claim.8LII / Legal Information Institute. SLAPP Suit As of early 2026, roughly 40 states have these laws. They let a defendant file an early motion to dismiss, and in many states a successful motion lets the defendant recover attorney’s fees from you. A weak case can leave you paying the other side’s legal costs, so this is worth taking seriously before filing.
If the Statements Are Online
A defamatory social media post can reach millions of people within hours, and digital content tends to resurface in search results long after it’s posted. Two legal realities shape what you can do about it.
The first is Section 230 of the Communications Decency Act. It provides that no internet platform or service provider can be treated as the publisher of content created by its users.9Office of the Law Revision Counsel. 47 USC 230 – Protection for Private Blocking and Screening of Offensive Material If someone posts a defamatory review about you on a platform, you can sue the person who wrote it, but the platform itself is generally shielded. Your realistic target is the individual poster.
The second reality is that posters are often anonymous. Identifying who is behind an account typically requires filing a “John Doe” lawsuit and then subpoenaing the platform or internet service provider for records that might reveal the person. Courts balance your right to pursue a claim against the poster’s First Amendment interest in anonymous speech, and many require you to show your underlying claim has enough merit before ordering disclosure. Service providers increasingly notify users when a subpoena hits, giving the poster a chance to fight it.
You Have Less Time Than You Think
Defamation claims have short statutes of limitations compared to most civil claims. Deadlines across the country typically range from one to three years from the date of publication, with one year being the most common. Some states set different deadlines for libel and slander. Missing the window almost always ends your claim permanently, no matter how strong it would otherwise be. The clock usually starts when the statement is first published or spoken, not when you discover it, though a few jurisdictions apply a discovery rule in limited circumstances.
What to Do Right Now
If someone is spreading falsehoods about you, the first days and weeks matter more than most people realize.
Preserve everything immediately. Screenshot every defamatory post, review, or message, but don’t rely on screenshots alone. Save the full URL with any unique post identifiers, capture the full page context including the poster’s profile and timestamps, and use a web archiving service like the Wayback Machine to create a time-stamped record. Assume the content could be deleted by tomorrow.
Send a cease-and-desist letter. A formal demand letter from an attorney asking the person to stop and remove existing content is a standard first step. It puts the other side on notice, which can matter later if you need to prove they kept making false statements after being told they were harmful. Sometimes the letter alone resolves the problem.
Check your state’s retraction rules. Roughly two-thirds of states have retraction statutes that may require you to formally demand a correction before filing suit. In some states, failing to send a timely retraction demand limits the damages you can recover or blocks the claim entirely.
Talk to an attorney early. Between the short filing deadlines, the evidentiary requirements, the anti-SLAPP risk, and the possibility that filing a lawsuit will amplify the very statements you want buried, these cases involve real strategic choices. Many defamation attorneys offer initial consultations to tell you whether your facts support a viable claim before you commit to the cost and public exposure of litigation.
