You can sue someone for defamation and harassment in civil court to recover money damages, obtain a court order stopping the behavior, or both. A civil case is separate from any criminal charges, and you only have to prove your version of events is more likely true than not, a standard called preponderance of the evidence.1Legal Information Institute. Burden of Proof Whether a lawsuit is actually worth pursuing depends on what you can prove, how much time has passed, and whether the person you want to sue has anything worth collecting.
What You Have to Prove
The legal theory you use depends on what the person did. Defamation covers false statements of fact that harmed your reputation. Intentional infliction of emotional distress (IIED) and civil assault cover threatening or abusive conduct that caused you psychological harm.
Defamation
Defamation comes in two forms. Libel is written or published; slander is spoken. In either case, you generally have to prove four things: the defendant made a false statement, communicated it to at least one other person, was at fault in making it, and caused you some recognizable harm.
Some false statements are treated as so damaging on their face that you don’t need to prove specific financial loss. These “per se” categories typically include false accusations of a crime, claims that you have a serious communicable disease, attacks on your professional competence, and false allegations of sexual misconduct. If the statement falls outside those categories, you have to connect it to an actual loss — a job you didn’t get, a contract that fell through, a client who walked away.
Intentional Infliction of Emotional Distress
IIED requires extreme and outrageous conduct that intentionally or recklessly caused severe emotional suffering. The bar is high. Ordinary rudeness, insults, and even repeated annoyances usually don’t qualify. The behavior has to go so far beyond the bounds of decency that a reasonable person would call it outrageous, not just rude.
Context does a lot of work here. A stranger yelling an insult at you on the street probably isn’t enough. A supervisor who systematically humiliates a subordinate for weeks, or a debt collector who uses daily threats and obscene language, is a different story. People in positions of authority are generally held to a stricter standard because their leverage amplifies the impact.
“Severe” is the other word doing real work. Being upset isn’t enough. Courts look at the intensity and duration of the distress and how it affected your daily life. Strong evidence includes therapy records, formal diagnoses, prescriptions tied to the distress, physical symptoms like insomnia or significant weight changes, journals documenting the impact over time, and testimony from people who witnessed changes in your behavior. Some courts still require physical manifestations, though the trend has moved toward accepting well-documented psychological harm on its own.
Civil Assault
A threat of physical harm can support a civil assault claim when it creates a reasonable fear of immediate bodily injury. No actual contact is required. You have to show you were aware of the threat and had reason to believe the person could carry it out right then. Someone standing in front of you with a raised fist is the classic example. A vague text saying “you’ll regret this someday” generally doesn’t qualify because the element of immediacy is missing.
The Higher Bar for Public Figures
The fault standard in a defamation case depends on who you are. A private individual generally only has to show the defendant was careless about the truth. A public official has to meet the far tougher standard the Supreme Court set in New York Times Co. v. Sullivan: actual malice, meaning the defendant either knew the statement was false or published it with reckless disregard for whether it was true.2Legal Information Institute. New York Times v Sullivan 1964 The Court later extended that standard to public figures more broadly, including celebrities, prominent business leaders, and anyone who has voluntarily injected themselves into a public controversy.3Legal Information Institute. First Amendment – Defamation
This is where most public-figure defamation cases collapse. Reckless disregard doesn’t mean sloppy reporting or failing to double-check. It means the defendant actually entertained serious doubts about the truth and published anyway. Proving someone’s state of mind is hard, and you have to establish it with convincing clarity rather than a bare majority of the evidence.
Opinion, Fact, and Online Posts
Only false statements of fact can be defamatory. Opinions are broadly protected. The line between them isn’t always clean. In Milkovich v. Lorain Journal Co., the Supreme Court asked whether a reasonable reader would interpret the statement as asserting verifiable facts about a person.4Legal Information Institute. Milkovich v Lorain Journal Co 497 US 1 1990 Courts look at the language, the surrounding context, and whether the claim can be objectively verified. Calling someone “the worst doctor in town” in an online rant reads differently from writing in a formal article that a specific doctor misdiagnosed a specific patient. The first sounds like opinion; the second implies a factual claim.
Online defamation follows the same rules, but with one important wrinkle: you generally cannot sue the platform. Section 230 of the Communications Decency Act provides that no online service “shall be treated as the publisher or speaker of any information provided by another information content provider.”5Office of the Law Revision Counsel. 47 US Code 230 – Protection for Private Blocking and Screening of Offensive Material Facebook, X, Yelp, Reddit, and similar platforms are almost always immune from defamation claims based on user posts, even after being notified. Your target has to be the person who posted the content. When that person is anonymous, lawyers typically file against a “John Doe” defendant and use subpoena power to force the platform to identify the user.
Defenses That Can Sink Your Case
Before filing, think about what the defendant will throw back at you. Several defenses can end a case quickly and expensively.
Truth. Truth is an absolute defense to defamation. A substantially true statement cannot be defamatory, no matter how much harm it causes. The defendant doesn’t have to prove every small detail; substantial truth is enough.
Privilege. Some settings carry absolute privilege, meaning statements made there cannot form the basis of a defamation claim no matter how false or malicious. Witness testimony in court is the clearest example — a lying witness may face perjury charges but cannot be sued for defamation over that testimony. Similar protection covers statements in legislative sessions and certain executive communications. Qualified privilege, which can be lost if abused, covers things like employer references and reports to law enforcement.
Anti-SLAPP statutes. SLAPP stands for strategic lawsuit against public participation, meaning a lawsuit filed mainly to silence a critic. Roughly 40 states plus the District of Columbia have anti-SLAPP laws that let a defendant file an early motion to dismiss by showing the lawsuit targets speech on a matter of public concern. The burden then shifts to you to show you have enough evidence to potentially win. If you can’t, the case gets thrown out early and you can be ordered to pay the defendant’s attorney’s fees. This is a real risk for borderline cases.
Retraction. Many states have retraction statutes that reduce a defendant’s exposure if they promptly publish a correction. The usual effect is to eliminate general damages (emotional distress and similar non-economic harms) and punitive damages, leaving you with only provable financial losses. Some statutes require you to demand a retraction before filing, and skipping that step can limit what you can recover.
What You Can Recover
Winning produces three possible categories of recovery, each with a different standard of proof.
Compensatory damages are meant to make you whole. Special damages cover economic losses: lost income, diminished earning capacity, lost business, and out-of-pocket costs like therapy, content removal, or relocation. These require documentation — tax returns, pay stubs, receipts. General damages cover non-economic losses: emotional distress, humiliation, anxiety, depression, sleep disruption, loss of enjoyment of life. These are harder to quantify, and some states limit them in slander cases unless the statement is defamatory per se.
Punitive damages exist to punish and deter rather than to compensate. Courts typically require evidence that the defendant acted intentionally and knew the conduct was likely to cause injury. The Supreme Court has indicated punitive awards should bear a reasonable relationship to compensatory damages, with the focus on how reprehensible the conduct was.6Legal Information Institute. Punitive Damages In practice, punitive damages are uncommon in defamation cases unless the behavior was egregious, and retraction statutes often eliminate them.
Injunctive relief. Money isn’t always what you need most. When harassment or threats are ongoing, a court can order the behavior to stop. A temporary restraining order can be issued without even notifying the defendant if you show through specific facts that immediate and irreparable harm will happen before they can be heard. A TRO issued without notice expires within 14 days unless the court extends it for good cause.7Legal Information Institute. Federal Rules of Civil Procedure Rule 65 – Injunctions and Restraining Orders After the TRO, the court schedules a preliminary injunction hearing where the defendant can respond. If you win at trial, the court can issue a permanent injunction. State courts have parallel procedures, and many states offer streamlined civil harassment restraining orders that move faster than full litigation. If threats are active, pursuing a TRO or restraining order should come first, even before the broader lawsuit is ready.
Deadlines to File
Every civil claim has a filing deadline, and missing it ends the case before it starts. Defamation deadlines range from as little as six months to three years depending on the state. The clock generally starts on the date the statement was first published, not when you discovered it, though some states apply a discovery rule that delays the start until you knew or reasonably should have known.
Most states follow the single publication rule, which means the limitations period runs from the original publication date and doesn’t reset every time the content is re-shared. IIED and civil assault deadlines also vary by state and typically run between one and three years. The clock can be paused in limited circumstances — if the defendant leaves the state, for example, or if you were a minor when the harm occurred. Given how short some of these windows are, getting legal advice early matters.
Evidence to Preserve Now
A case lives or dies on documentation, and the time to start is the moment the conduct begins, not when you decide to file.
Identify the defendant by full legal name and address. You cannot serve someone you cannot find. Build a chronological log of every incident with the date, time, location, what was said or done, and who else was present. This log becomes the backbone of your complaint and keeps your memory sharp as the case drags on.
Preserve statements in their original format. Print emails with full headers. Screenshot social media posts showing the date, the poster’s profile, and any comments or shares. Export text messages rather than relying on phone screenshots that can be lost if the device breaks. For threats, save voicemails, photograph written notes, and keep copies of any police reports you’ve filed.
Identify witnesses early. Anyone who saw the conduct, heard the statement, or watched the impact on you is potentially useful. Get full names and current contact information. Your evidence and witness list will form the core of the “Parties” and “Statement of Claim” sections of your complaint.8United States Courts. Complaint for a Civil Case
The Filing Process and Its Costs
Once your evidence is organized, the mechanics follow a predictable path.
You file the complaint with the clerk of court in the appropriate jurisdiction. Filing fees vary by court and the amount of damages sought. If you can’t afford the fee, federal courts allow you to request a waiver by filing to proceed in forma pauperis under 28 U.S.C. § 1915, which requires an affidavit showing you can’t pay.9Office of the Law Revision Counsel. 28 USC 1915 – Proceedings in Forma Pauperis State courts have similar waiver processes.
After the clerk assigns a case number, you have to formally deliver the summons and complaint to the defendant. That usually means a professional process server or the local sheriff. You cannot serve the papers yourself. Service generally costs between $20 and $100, with higher fees for rush requests or hard-to-locate defendants.
In federal court, the defendant has 21 days after being served to answer.10United States Courts. Federal Rules of Civil Procedure State deadlines commonly range from 20 to 30 days. If the defendant ignores the lawsuit and the deadline passes, you can ask for a default judgment.11United States District Court Middle District of Florida. Civil Case Flowchart A default looks like winning, but collecting on it is often difficult — a defendant who ignores a lawsuit tends to ignore a judgment too.
If the defendant does respond, the case moves into discovery, the formal exchange of information before trial. The main tools are interrogatories (written questions answered under oath), depositions (in-person questioning under oath, recorded by a court reporter), and document requests. Subpoenas can also compel third parties, like internet providers or social media companies, to produce records. Discovery is where cases get expensive. Both sides have to respond to the other’s requests, and the process can drag on for months. It’s also where many cases settle, because once both sides see the actual evidence, the likely outcome becomes clearer.
A practical note on fees: defamation and harassment cases are usually not taken on contingency. Most attorneys in this space bill hourly, which means you carry the financial risk throughout. Before filing, be honest with yourself about whether the likely recovery justifies the cost. A defendant with no assets or income may not be worth suing even when the case is strong. That’s a hard conversation to have, but it saves real money and real frustration.
