Quick answer: To sue for online defamation, you need a false statement of fact, publication to a third party, fault, and documented damages. File in the appropriate jurisdiction, potentially using a "John Doe" complaint for anonymous defendants. While litigation is a last resort, it can be effective for provably defamatory content causing real, continuing harm when other removal methods fail.
To sue for online defamation you need (1) a false statement of fact (not opinion), (2) publication to a third party, (3) fault on the part of the defendant, and (4) damages you can document. File in the jurisdiction where the plaintiff lives or was harmed, using a "John Doe" complaint if the reviewer is anonymous. Typical timeline: 30 days for a cease and desist and platform notice; 60 to 120 days to file, serve, and complete initial discovery; 6 to 18 months to trial or settlement. Full-litigation cost in the US and UK runs $8,000 to $75,000 for a standard single-review case, with recovery of legal fees possible in some jurisdictions. Small-claims filings under $10,000 are faster and cheaper where they apply. About 68% of cases settle before trial once the defendant is identified and served.
Most business owners do not want to sue. They want the review gone. Litigation is the last tool on the shelf - slower, costlier, and more public than a cease and desist or a platform report. But when the review is provably defamatory, the reviewer will not remove it, the platform will not act on the standard notice, and the damage is real and continuing - litigation is the tool that works. This guide is the honest, non-lawyer-marketing walkthrough of what filing actually looks like in 2026.
Adam runs the removal desk at BGR Review; the escalation ladder below is what we run for clients when platform reporting and counsel-drafted cease and desist letters have failed. Nothing here is legal advice. It is operational context on how defamation cases actually proceed. Retain counsel in your jurisdiction before filing anything.
What qualifies as online defamation you can sue over
Every common-law jurisdiction (US, UK, Canada, Australia) requires four elements. All four must be present.
- False statement of fact. "The food was cold and inedible" is opinion. "They served me raw chicken and I got salmonella" is a factual claim. Truth is an absolute defence.
- Publication to a third party. An online review is inherently published.
- Fault. Negligence for private-figure plaintiffs; actual malice (knew it was false or reckless disregard) for public figures. Most business owners are private figures.
- Damages. Actual harm (lost revenue, cancelled bookings, reputational damage). Some US states recognise per se defamation for false claims of a crime, professional incompetence, or a loathsome disease - damages are presumed in those cases.
If any element is missing, the case will be dismissed at motion-to-dismiss or on summary judgment. Do not file over an opinion, a harsh but truthful complaint, or a review from a real customer with a genuine grievance, no matter how badly written.
Anti-SLAPP: the biggest US-side risk
Roughly 33 US states have anti-SLAPP statutes designed to protect free speech from meritless suits. If the defendant successfully argues the review is protected speech and you cannot show a "probability of prevailing", the court can dismiss and order you to pay the defendant's legal fees. In California, Texas, and DC in particular, anti-SLAPP motions are common and effective.
Practical read: filing in an anti-SLAPP state without airtight evidence is expensive. Your counsel will assess anti-SLAPP exposure before filing. In borderline cases they will often push you toward the platform report path or a demand-letter strategy rather than filing.
The escalation ladder before filing
Courts do not look favourably on plaintiffs who filed suit without trying to resolve first. Every filing we support runs through the escalation ladder in order.
- Platform in-flow report. Free. 14.3% success rate in our tracking. Takes 3 to 21 days.
- Platform legal notice via counsel. Small counsel cost. Adds meaningfully to the rate for defamation-flavour reports.
- Cease and desist to the reviewer. $600 to $1,500 through outside counsel. 41% voluntary compliance within 21 days for lawyer-signed letters.
- Second cease and desist naming jurisdiction and intent to file. Small additional counsel cost. Adds a further 5 to 10% to compliance.
- File suit. The remaining cases where none of the above worked and the review is truly defamatory.
By the time filing is the right call, you have already invested in evidence, letters, and platform reports. That work is the foundation of the complaint - all of it goes in the pleadings.
Jurisdiction: where to file
Defamation is filed in the state or country where the plaintiff resides, where the defendant resides, or where the harm was suffered. For US business owners, the practical options:
- Home state, state court. Standard route for local plaintiffs. Filing fee typically $200 to $500. Discovery rules and anti-SLAPP exposure vary state to state.
- Federal court under diversity jurisdiction. Requires plaintiff and defendant in different states and damages over $75,000. Slower and more expensive but often preferable for cross-state defendants.
- Small claims. Cap ranges $2,500 (Kentucky) to $25,000 (Tennessee). No lawyer required, no anti-SLAPP motion available in most small-claims courts, faster resolution (60 to 120 days). Best when damages are modest and the defendant is identified.
In the UK, defamation claims go through the High Court or, where damages are modest, the county court. The Defamation Act 2013 requires "serious harm" for corporate claimants - "serious financial loss" specifically. Bring documentation.
Suing an anonymous reviewer: the John Doe path
Most negative online reviews are pseudonymous. You cannot serve a lawsuit on "AmazonReviewer_842". The John Doe path handles this.
- File the complaint against "John Doe 1" (and John Doe 2, 3 if there are multiple linked accounts).
- After filing, request expedited discovery from the court - a court order allowing you to subpoena the platform for the account holder's registration information (email, phone, IP).
- Serve the subpoena on Google, Yelp, Booking.com, Meta, Reddit, or the relevant platform's designated legal contact.
- Platform notifies the account holder that a subpoena has been served - the account holder has typically 21 days to object. If they do not object, the platform releases the information.
- Amend the complaint to name the real defendant and serve them personally.
This process typically takes 60 to 120 days before you have a named, served defendant. Costs run $3,000 to $12,000 in counsel time depending on how many objections and how many platforms are involved. Some reviewers move quickly to voluntary settlement once they realise they have been unmasked - roughly 30% in our observation.
Damages: what you can actually recover
Defamation damages come in three categories in most jurisdictions:
- Special damages. Provable, quantifiable losses. Cancelled bookings, dropped contracts, revenue variance vs the trailing 12-week baseline, PR and remediation costs. Bring receipts.
- General damages. Reputational and emotional harm. Awarded at the fact-finder's discretion, typically in the range of $5,000 to $75,000 for a single-review case involving a small business, higher for larger cases and per-se defamation.
- Punitive damages. Awarded when the defendant acted with actual malice or was part of a coordinated campaign. Cap varies by state and country; some jurisdictions do not allow them.
Some jurisdictions also allow legal-fee recovery when defamation is proven - the UK's costs-follow-the-event rule and certain US anti-SLAPP fee provisions in reverse. Ask counsel about fee shifting when scoping the case.
Realistic cost and timeline
| Stage | US typical cost | UK typical cost | Time |
|---|---|---|---|
| Complaint drafting and filing | $3,000 to $8,000 | £3,000 to £7,000 | 2 to 4 weeks |
| John Doe discovery and unmasking | $3,000 to $12,000 | £4,000 to £10,000 | 60 to 120 days |
| Initial discovery (interrogatories, docs) | $5,000 to $15,000 | £5,000 to £12,000 | 60 to 90 days |
| Anti-SLAPP or motion to dismiss defence | $5,000 to $20,000 (US only, when raised) | N/A | 60 to 120 days |
| Settlement negotiation | $2,000 to $8,000 | £2,000 to £6,000 | 30 to 90 days |
| Trial (if not settled) | $25,000 to $75,000+ | £30,000 to £120,000+ | 6 to 18 months from filing |
About 68% of defamation cases in our observation settle before trial once the defendant is unmasked and served. Most settlements combine removal of the post, a written retraction, and modest damages (typically $2,000 to $15,000). Trials are rare because they are expensive on both sides and the outcome is uncertain.
By the time a business owner is ready to file, they usually want two things: the review gone and an apology. Damages are third. Court knows this, and most settlements resolve on the first two with a nominal payment on the third. - Adam, Head of Review Removal, BGR Review.
What you need before calling a defamation lawyer
- Full-browser screenshots of the review, dated, with URL bar visible.
- archive.org captures at the review URL taken as soon as possible.
- Booking system, POS, CCTV, or PMS records that disprove the specific factual claim.
- Customer database export showing the reviewer name/email was not a customer, if that is the theory.
- Revenue variance for the 12 weeks before and after the review posted.
- Cancellation logs and any direct customer feedback naming the review.
- All prior correspondence: platform report receipts, cease and desist letters, reviewer responses.
Counsel will thank you. Every hour of paralegal time you save with an organised evidence packet is $150 to $400 off the bill.
When suing is the wrong tool
- The review is true. Even ugly-true. Litigation loses. Focus on operational fix and response.
- The review is opinion. "Worst service ever" is protected speech. No court will award damages.
- The defendant is judgment-proof. Winning a $30,000 judgment against someone with no assets is a paper victory. Small-claims may still be worth it for the removal leverage, but full litigation is not.
- Damages are under $2,000 and platform paths still exist. Small-claims may fit; full litigation does not.
- You are a public figure or public official. The "actual malice" standard is very hard to meet, and losing is expensive. Retain specialist counsel and be honest about the win probability.
How BGR Review supports the pre-litigation phase
Our removal desk does not litigate. What we do is run the escalation ladder up to and including counsel-drafted cease and desist letters and platform legal notices - the steps that resolve 60 to 70% of defamation cases before filing is necessary. When filing is the right call, we hand the evidence packet and the paper trail to your defamation counsel and step back. The service is pay-after-success on the removal itself - $0 upfront, $449 per successfully removed review across the pre-litigation ladder. Details on the Google review removal service page.
Suing for online defamation FAQ
Can I sue for a bad online review?
Only when the review contains a provably false factual claim (not opinion), you can document actual harm, and the defendant is identifiable or unmaskable via platform subpoena. Truthful reviews, opinion, and rhetorical hyperbole are all protected. Try platform reporting and a lawyer-drafted cease and desist first - full litigation is the last tool.
How much does it cost to sue for online defamation?
Standard single-review cases run $8,000 to $75,000 in the US and £10,000 to £120,000 in the UK, depending on whether the case settles or reaches trial and whether an anti-SLAPP motion is filed. Small-claims filings under the state cap are faster and cheaper ($100 to $500 in filing fees, no lawyer required). About 68% of cases settle before trial.
Can I sue an anonymous reviewer?
Yes, via a "John Doe" complaint. You file against John Doe 1, get court-ordered expedited discovery, subpoena the platform for account holder information, wait through the platform's user-objection window (typically 21 days), then amend the complaint to name the real defendant. This unmasking phase takes 60 to 120 days and costs $3,000 to $12,000 in counsel time.
What is anti-SLAPP and does it apply to my case?
Anti-SLAPP statutes exist in about 33 US states and are designed to dismiss meritless suits that chill free speech. If the defendant successfully argues the review is protected speech and you cannot show probability of prevailing, the court can dismiss and order you to pay the defendant's legal fees. California, Texas, and DC have the strongest anti-SLAPP regimes. UK does not have anti-SLAPP but has its own free-expression defences under the Defamation Act 2013.
How long does a defamation lawsuit take?
From filing to settlement, typically 6 to 12 months. From filing to trial, 12 to 24 months. Small-claims resolves faster (60 to 120 days). Unmasking an anonymous defendant adds 60 to 120 days before named-defendant discovery can begin. Most cases settle after unmasking and initial discovery reveals the strength of both sides' evidence.
Will I actually get money if I win?
Sometimes. Special damages (documented lost revenue, cancelled bookings) recover most reliably. General damages for a small-business single-review case typically range $5,000 to $75,000 when awarded. Punitive damages are rare. Collectability depends on the defendant's assets - a paper judgment against a judgment-proof defendant is worth nothing beyond the removal leverage.
Should I try a cease and desist letter before suing?
Yes, in almost every case. Lawyer-drafted cease and desist letters resolve about 41% of defamation cases within 21 days at a fraction of litigation cost. Courts also look more favourably on plaintiffs who tried to resolve the dispute first. Skip the letter and file directly only when the reviewer is fully anonymous (John Doe filing is the mechanism to unmask them) or when there is an ongoing coordinated attack requiring emergency injunctive relief.
Frequently Asked Questions
What qualifies as online defamation I can sue over?
To win a defamation case, four elements must be present: a false statement of fact (not opinion), publication to a third party, fault on the part of the defendant (negligence or actual malice), and documentable damages. If any element is missing, the case is likely to be dismissed. Do not sue over opinions or truthful, albeit harsh, complaints.
Can I sue for defamation if the reviewer is anonymous?
Yes, you can initiate a lawsuit against an anonymous reviewer. This typically involves filing a "John Doe" complaint and then using legal discovery processes, such as subpoenas, to compel platforms or internet service providers to disclose the reviewer's identity. This step allows you to properly serve the defendant and proceed with the case.
How long does an online defamation lawsuit take?
The timeline varies significantly. After an initial cease and desist and platform notice (around 30 days), filing, serving, and initial discovery can take 60 to 120 days. A full lawsuit, including trial or settlement, can range from 6 to 18 months. Small claims cases are generally faster, while complex cases take longer.
What are the typical costs associated with suing for online defamation?
In the US and UK, standard single-review defamation cases can cost $8,000 to $75,000 for full litigation. These costs include attorney fees, court fees, and discovery expenses. Recovery of legal fees is possible in some jurisdictions. Small claims court offers a less expensive option for eligible cases.
What is anti-SLAPP legislation, and how does it affect defamation suits?
Anti-SLAPP (Strategic Lawsuit Against Public Participation) laws exist in roughly 33 US states to protect free speech. If a defendant successfully argues the defamatory statement is protected speech, and you cannot show a "probability of prevailing," the court may dismiss your case and order you to pay the defendant's legal fees. This strongly influences filing decisions.
