In plain language: Offense describes the wrongful act itself, like slander or wrongful eviction, that triggers certain liability coverage. Unlike bodily injury claims, coverage attaches when the insured commits the act, not when someone gets physically hurt.
Technical definition: Offense is the coverage trigger used in the Personal and Advertising Injury section of the CGL form (Coverage B). Enumerated offenses, such as false arrest, libel, slander, and invasion of privacy, replace the occurrence trigger used in Coverage A for bodily injury and property damage.

Key Takeaways
- Offense is the trigger that activates Coverage B of a CGL policy, tying coverage to a wrongful act like libel, slander, or false arrest rather than physical injury.
- Agencies must recognize offense-based claims because they often arrive disguised as personal disputes, like a defamation lawsuit against a restaurant owner, rather than obvious liability events.
- The most common pitfall is assuming all liability claims follow the occurrence trigger, which causes CSRs to misroute Coverage B claims or overlook exclusions unique to enumerated offenses.
- A strong best practice is training staff to read the full list of enumerated offenses in the policy definitions section before telling a client that a non-physical injury claim is or is not covered.
What Is Offense in Insurance?
Offense is the mechanism that determines when Coverage B of the standard CGL form responds to a claim. The CGL policy splits liability exposure into two tracks. Coverage A uses the occurrence trigger, meaning coverage attaches when an accident causes bodily injury or property damage during the policy period. Coverage B uses the offense trigger instead, meaning coverage attaches when the insured commits one of several specifically listed wrongful acts.
The distinction exists because many legal wrongs, like slander or wrongful eviction, do not involve physical injury or property damage at all. Insurers needed separate trigger language to address these non-physical torts, which is why ISO built a distinct definitions section listing exactly which offenses qualify. The CG 00 01 form enumerates offenses including false arrest, malicious prosecution, wrongful eviction, libel, slander, and violation of a person's right of privacy.
Consider a property management company that evicts a tenant believing the lease had expired, but the tenant later proves the eviction was unlawful. The tenant sues for wrongful eviction. Coverage A would not respond, because no bodily injury or property damage occurred. Coverage B responds instead, because wrongful eviction is a listed offense that occurred during the policy period, even though the legal dispute unfolds over many months afterward.
How Does Offense Work?
- The wrongful act. The insured commits an act, such as publishing a defamatory statement or detaining a customer without cause, that falls within the policy's list of enumerated offenses.
- The timing check. The carrier confirms the offense occurred during the policy period, since Coverage B is still occurrence-triggered in the sense that the act's timing, not the claim's filing date, controls.
- The claim or suit. The injured party files a claim or lawsuit alleging one of the enumerated offenses, naming the insured as the defendant.
- The coverage review. The carrier matches the allegation against the specific offense definitions and applicable exclusions, such as the knowing violation exclusion or media-related exclusions.
- The response. The carrier accepts the claim under Coverage B, denies it if the allegation does not match an enumerated offense, or reserves rights pending further investigation.
Real Claim Examples Involving Offense
Defamation claim against a restaurant owner
A restaurant owner posted online that a former employee had stolen from the register, though no theft was ever proven. The former employee sued for slander and sought damages for reputational harm. The restaurant's CGL policy responded under Coverage B because slander is an enumerated offense, and the statement was made during the active policy period.
Wrongful detention at a retail store
A loss prevention officer detained a shopper for over an hour based on a mistaken shoplifting suspicion, and the shopper later sued for false imprisonment. The retailer's agent initially assumed general liability would not apply since no physical injury occurred. Coverage B picked up the claim because false imprisonment is a listed offense, and defense costs were covered from the point suit was filed.
Invasion of privacy by a property manager
A property management firm posted a tenant's eviction notice, including personal financial details, on a public bulletin board inside the apartment complex. The tenant sued for invasion of privacy, and the carrier accepted the claim under Coverage B after confirming the disclosure met the policy's enumerated offense definition. The claim highlighted how operational habits, not just intentional misconduct, can trigger offense-based coverage.
Offense vs. Occurrence: What Is the Difference?
Offense and occurrence are both coverage triggers within the CGL form, but they apply to different coverage parts and different types of harm. Occurrence governs Coverage A for bodily injury and property damage from an accident, while offense governs Coverage B for specifically enumerated wrongful acts like libel or false arrest.
| Comparison area | Offense | Occurrence |
|---|---|---|
| Primary use case | Non-physical torts like defamation, false arrest, wrongful eviction | Physical bodily injury or property damage from an accident |
| Coverage / concept type | Coverage B trigger (Personal and Advertising Injury) | Coverage A trigger (Bodily Injury and Property Damage) |
| Typical exclusions | Knowing violation of rights, criminal acts, contractual liability | Expected or intended injury, pollution, professional services |
| Who is most affected by errors | Media, retail, hospitality, and real estate operations | Contractors, manufacturers, and premises-based businesses |
| Common mistakes | Assuming non-physical claims are automatically excluded | Assuming all injuries need a single identifiable accident |
What Are the Most Common Mistakes With Offense?
- Agencies sometimes tell clients that a defamation or false arrest claim is not covered simply because no physical injury occurred, overlooking that Coverage B exists precisely for these situations.
- CSRs frequently fail to check whether the alleged offense matches the exact enumerated list in the policy, which creates false assurances when the claim actually falls outside the definition.
- Employment-related claims, like wrongful termination framed as defamation, often trigger the Employment-Related Practices Exclusion (CG 21 47), and missing this endorsement leads to coverage surprises.
- Documentation gaps around when the alleged offense actually occurred can delay claims, since the offense trigger still depends on precise timing within the policy period.
- Some producers assume Coverage B sublimits match the general aggregate, when many policies carry separate, lower limits for personal and advertising injury that clients are never told about.
How to Explain Offense to a Client
Explaining Offense to a personal lines client
Think of offense as the part of your policy that protects you if someone sues you for something you said or did, not for a physical injury. If a neighbor claims you damaged their reputation or wrongly accused them of something, this is the type of coverage that could respond. It is a narrower, more specific list than general bodily injury coverage.
Explaining Offense to a small business owner
Your general liability policy has two tracks: one for physical injuries and property damage, and one for specific wrongful acts like false arrest, libel, or wrongful eviction. That second track is triggered by offense, meaning the covered event is the act itself, not an injury. If an employee's actions lead to a defamation or privacy lawsuit, this is usually where your policy responds.
Explaining Offense to a CFO or risk manager
Coverage B operates on an offense trigger, meaning the enumerated wrongful act must occur within the policy period, independent of when the claim is filed or when damages manifest. This matters for program design because the sublimits, exclusions, and definitions for Coverage B often diverge materially from Coverage A, particularly around employment practices, media content, and contractual relationships. Any gap analysis should treat offense-triggered exposures as a distinct underwriting conversation, not an afterthought folded into the general liability review.
Frequently Asked Questions About Offense
What counts as an enumerated offense under a CGL policy?
Enumerated offenses typically include false arrest, detention, or imprisonment, malicious prosecution, wrongful eviction, wrongful entry, libel, slander, and violation of a person's right of privacy. The exact list appears in the policy's Personal and Advertising Injury definitions section, and insurers can modify it through endorsement. Agencies should always confirm the specific wording in the policy they are placing rather than assuming a standard list applies.
Does offense coverage require physical injury to occur?
No, offense coverage does not require physical injury. Coverage B exists specifically to address wrongful acts like defamation or wrongful eviction that cause reputational, emotional, or dignitary harm without any physical injury component. This is the key distinction between the offense trigger and the occurrence trigger used for bodily injury and property damage claims.
Can an offense claim and an occurrence claim arise from the same incident?
Yes, a single incident can sometimes trigger both coverage parts if it involves both a physical injury and an enumerated wrongful act. For example, a wrongful detention that escalates into a physical altercation could generate both a false imprisonment allegation under Coverage B and a bodily injury claim under Coverage A. Carriers evaluate each allegation separately against its respective trigger and exclusions.
Why do employment-related offense claims often get denied?
Many CGL policies carry the Employment-Related Practices Exclusion, often added through an endorsement like CG 21 47, which bars coverage for claims arising from the employment relationship, including wrongful termination, discrimination, and harassment. Even though these claims might otherwise resemble enumerated offenses like defamation, the exclusion removes them from Coverage B entirely. Agencies should recommend a standalone Employment Practices Liability policy to close this gap.
Is the offense trigger the same as a claims-made trigger?
No, offense and claims-made describe different concepts entirely. Offense refers to what kind of wrongful act triggers coverage, while claims-made refers to when a claim must be reported relative to the policy period. A policy can combine an offense-based coverage part with either an occurrence form or a claims-made form, though standard CGL policies typically use occurrence form for both Coverage A and Coverage B.
Related Insurance Terms
- Occurrence: The coverage trigger used for Coverage A of a CGL policy, requiring an accident causing bodily injury or property damage during the policy period, distinct from the wrongful-act basis of offense.
- Personal and Advertising Injury: The broader coverage category, labeled Coverage B, under which offense-based claims like libel and false arrest are evaluated and paid.
- Claims-Made Trigger: A policy structure requiring both the wrongful act and the claim to occur within the policy period or an extended reporting period, often used alongside offense-based definitions in professional and media liability forms.
- Enumerated Peril: A listed, specifically named cause of loss in property insurance, conceptually similar to how enumerated offenses function as a defined list rather than an open-ended trigger.
- Bodily Injury: The physical harm requirement that triggers Coverage A under the occurrence trigger, standing in direct contrast to the non-physical wrongful acts that trigger offense-based Coverage B.
- Employment-Related Practices Exclusion: A common CGL endorsement that removes coverage for employment-based claims, frequently colliding with offense-triggered allegations like defamation arising from workplace disputes.
