In plain language: Defamation happens when someone makes a false statement about a person or business that damages their reputation. It can be spoken (slander) or written (libel). Businesses get sued for defamation when employees, marketing content, or online reviews spread false claims about competitors, customers, or former employees.
Technical definition: Defamation is a false statement of fact communicated to a third party that injures another's reputation, giving rise to tort liability. Under commercial general liability policies, defamation falls within the "personal and advertising injury" coverage grant, defined in ISO form CG 00 01, separate from bodily injury and property damage.

Key Takeaways
- Defamation is a false statement, spoken or written, that damages a person's or business's reputation and can trigger liability coverage.
- Agencies need to understand defamation because it is one of the most litigated offenses under the personal and advertising injury section of a CGL policy, not bodily injury or property damage.
- The most common misunderstanding is assuming defamation claims are automatically covered; many CGL policies carry exclusions for knowing violation of rights, employment-related statements, or content posted on the insured's own website or social media.
- A quick win for agencies is confirming whether a client's CGL form includes the employment-related practices exclusion (CG 21 06), since HR-driven defamation claims, like false statements in reference checks, are a frequent and often uninsured exposure.
What Is Defamation in Insurance?
Defamation is a civil wrong, or tort, that occurs when a false statement of fact is communicated to someone other than the person it's about and causes reputational harm. Insurance treats defamation not as bodily injury or property damage but as a distinct category called personal and advertising injury. This distinction exists because defamation damages intangible interests, reputation and standing in the community, rather than physical harm or damaged property.
Carriers built this coverage because businesses face real exposure from everyday communications: employee reference letters, marketing claims about competitors, online reviews, and social media posts. A single careless statement can trigger a lawsuit with significant defense costs even when the underlying claim has little merit. The coverage grant exists to protect businesses from the financial fallout of these disputes, not to encourage false statements.
Consider a landscaping company owner who tells a potential customer that a competitor "steals from clients and does shoddy work," based on nothing but rumor. The competitor sues for slander, alleging lost business and reputational harm. If the landscaping company carries CGL coverage with personal and advertising injury protection, the insurer typically defends the suit and pays covered damages, subject to policy exclusions and limits.
How Does Defamation Work?
- The statement. An individual or business makes a false statement of fact about another party, either verbally (slander) or in writing (libel), and communicates it to a third party.
- The harm. The statement causes measurable damage to the subject's reputation, business relationships, or earning capacity, which the injured party must typically prove.
- The claim. The injured party files a lawsuit or sends a demand letter alleging defamation and seeking damages for reputational and financial harm.
- The tender. The insured business notifies its liability carrier and tenders the claim under the personal and advertising injury section of its CGL policy.
- The coverage determination. The insurer reviews the claim against policy exclusions, such as the employment-related practices exclusion or knowing falsity exclusion, then decides whether to defend, settle, or deny.
Real Claim Examples Involving Defamation
Former employee reference check gone wrong
A regional staffing agency's HR manager told a prospective employer that a former employee "was fired for theft," when the employee had actually resigned voluntarily. The former employee sued for slander after losing the new job offer. Because the agency's CGL policy included the employment-related practices exclusion (CG 21 06), the carrier denied coverage, leaving the agency to fund its own defense and settlement.
Online review dispute between competing contractors
A roofing contractor posted a Google review under a fake name claiming a rival contractor "used illegal labor and faked inspections." The rival sued for libel and traced the post back to the contractor's IP address. The CGL carrier initially reserved rights due to a possible knowing-violation exclusion but ultimately defended the claim since the statement, while reckless, wasn't proven to be a deliberate lie at the time of posting.
Retail manager's public accusation of shoplifting
A retail store manager loudly accused a customer of shoplifting in front of other shoppers, though the customer had paid for the item and simply forgotten to remove a security tag. The customer sued for slander and emotional distress. The store's CGL policy covered the defense and eventual settlement under personal and advertising injury, since the incident arose from store operations and wasn't excluded employment-related conduct.
Defamation vs. Product Disparagement: What Is the Difference?
Defamation involves false statements that harm a person's or business's general reputation, while product disparagement specifically targets false statements about the quality or value of a company's goods or services. Both fall under the personal and advertising injury coverage grant in a standard CGL policy, but they arise from different fact patterns and often require different proof.
| Comparison area | Defamation | Product Disparagement |
|---|---|---|
| Primary use case | False statements about a person or company's character or conduct | False statements about the quality, safety, or value of a specific product |
| Coverage / concept type | Personal and advertising injury under CGL | Personal and advertising injury under CGL, sometimes called trade libel |
| Typical exclusions | Employment-related practices, knowing falsity, insured's own website content | Same exclusions, plus exclusions tied to advertising activities the insured controls |
| Who is most affected by errors | HR departments, executives, sales staff making unverified claims | Marketing and sales teams making comparative advertising claims |
| Common mistakes | Assuming truth is irrelevant; failing to document factual basis for statements | Confusing disparagement with legitimate competitive advertising |
What Are the Most Common Mistakes With Defamation?
- Assuming all defamation claims are covered under CGL, when many policies exclude employment-related statements through endorsements like CG 21 06, leaving HR-driven claims uninsured.
- Failing to recognize that truth is an absolute defense to defamation, so agents should remind clients that documented, factual statements carry far less legal risk than unverified accusations.
- Overlooking that social media and online review posts by employees or owners can trigger the same personal and advertising injury exposure as traditional print or broadcast statements.
- Believing personal lines homeowners policies automatically cover defamation claims, when many personal liability sections either exclude it or cap coverage well below commercial limits.
- Missing that some CGL forms exclude injury arising from statements made with knowledge of their falsity, which can gut coverage in cases involving malicious intent.
- Neglecting to explain to clients that defense costs for defamation suits often exceed eventual settlement amounts, making the duty-to-defend provision the most valuable part of the coverage.
How to Explain Defamation to a Client
Explaining defamation to a personal lines client
Defamation means saying or writing something false about someone that damages their reputation, and yes, it can happen from a heated social media post or a bad-mouthing comment to a neighbor. Your homeowners policy may offer limited personal liability coverage for this, but it's not automatic and often has lower limits than you'd expect. If you're active on social media or run a side business from home, we should talk about whether you need additional protection.
Explaining defamation to a small business owner
Defamation coverage protects your business if an employee, a manager, or even you make a false statement that damages someone's reputation, like accusing a customer of theft or badmouthing a competitor. It falls under the personal and advertising injury part of your general liability policy, not your standard bodily injury or property damage coverage. One important gap to know about: statements related to hiring, firing, or employee references are often excluded, so if that's a real risk for your business, we should discuss employment practices liability insurance separately.
Explaining defamation to a CFO or risk manager
Your CGL policy's personal and advertising injury coverage responds to defamation claims, but the scope depends heavily on the exclusions attached to your specific form, particularly around employment-related practices and knowing violations of rights. Given your industry's exposure to public statements, whether through marketing, customer service interactions, or executive commentary, I'd recommend we review your current exclusions endorsement against your actual risk profile. We should also evaluate whether a media liability or EPLI policy makes sense to close gaps the standard CGL leaves open.
Frequently Asked Questions About Defamation
Does general liability insurance cover defamation claims?
Standard commercial general liability policies typically cover defamation under the personal and advertising injury section, subject to exclusions. Coverage can be limited or eliminated entirely if the statement relates to employment practices, was made with knowledge of its falsity, or was posted on the insured's own website, depending on the specific endorsements attached to the policy.
What's the difference between libel and slander?
Libel refers to defamation in written or published form, such as a social media post, article, or email. Slander refers to spoken defamation, like a verbal accusation made in person or over the phone. Both fall under the broader personal and advertising injury coverage grant in most liability policies.
Can a business be sued for a negative online review?
A business generally cannot be sued for simply receiving a negative review, but the business itself can be sued if it or its employees post false statements about a competitor or customer online. Courts have consistently held that opinions are protected speech, while false statements of fact are not, which is why the specific wording of a review or post matters in any defamation claim.
Is truth a defense against a defamation claim?
Truth is generally an absolute defense against defamation claims in the United States, meaning a true statement cannot be defamatory no matter how damaging it is to someone's reputation. This is why documentation matters so much for businesses, especially in employment situations where accurate records can prevent a defamation claim from succeeding.
Does homeowners insurance cover defamation lawsuits?
Many homeowners policies include limited personal liability coverage that can respond to defamation claims arising from personal, non-business activities. Coverage terms vary significantly by carrier, and some policies exclude defamation entirely or cap it well below the standard liability limit, so agents should confirm the specific policy language rather than assume coverage exists.
Why would an insurer deny a defamation claim?
Insurers commonly deny defamation claims when the statement falls under an employment-related practices exclusion, when the insured knew the statement was false at the time it was made, or when the claim arises from content posted on the insured's own website or app, which many CGL forms specifically exclude. Reviewing the exact exclusionary language on a client's policy before a claim happens is the best way to avoid a surprise denial.
