Wrongful Act
A wrongful act is the actual or alleged error, omission, misstatement, or breach of duty that triggers coverage under a management or professional liability policy. The exact definition is written into each policy and varies by coverage type.

How a wrongful act works
Liability policies respond to claims that arise from a defined event. In management and professional liability, that event is the wrongful act. The definition differs by policy type:
- Directors and officers (D&O): commonly an actual or alleged act, error, omission, misstatement, misleading statement, neglect, or breach of duty by an insured person in their insured capacity.
- Errors and omissions (E&O): an act, error, or omission in the course of performing professional services, often as those services are defined in the policy.
The words "actual or alleged" mean a claim can trigger the policy based on what is asserted, before anything is proven. Most professional and management policies are also claims-made: the claim must be made during the policy period, and any retroactive date requires the wrongful act to have occurred on or after it.
Wording such as "actual or alleged" cuts both ways. It helps trigger a defense, but insurers still assess whether the allegations fall within coverage, and they may reserve rights while a claim is pending.
Wrongful act vs. related terms
- Wrongful act vs. claim. The wrongful act is the alleged conduct. A claim is the demand, lawsuit or proceeding that arises from it. Under a claims-made policy, both timing and the claim itself matter.
- Wrongful act vs. occurrence. General liability policies are typically triggered by an occurrence, an event causing injury or damage. Management and professional liability policies are triggered by wrongful acts.
- Wrongful act vs. professional services. In E&O, the act has to arise out of services defined in the policy. In D&O, the act has to be committed in an insured capacity.
- Wrongful act vs. loss. The wrongful act is the cause, and the loss is the money the policy may pay, such as defense costs, settlements or judgments, as defined in the policy.
Example
An investor in a hypothetical startup sues, alleging the CFO made misleading statements in a fundraising presentation. The allegation is a wrongful act in an officer's capacity, so the D&O policy may respond to defense costs. If a court later finds intentional fraud, a conduct exclusion may apply under the policy's terms.
A second example
A hypothetical payments software vendor is sued by several customers who each allege that the same integration error duplicated payments. Each customer alleges an error in the performance of technology services, which the E&O policy may treat as a wrongful act. Because the claims share the same underlying defect, the policy may treat them as interrelated and apply a single limit and policy period. Whether the services fall within the policy's definition and how interrelated acts are treated are both set by the wording.
What to watch for
- Capacity. Coverage typically applies only to acts in an insured capacity, such as a director or officer, not personal or unrelated conduct.
- Intentional conduct. Deliberate fraud and criminal acts are typically excluded, and policies generally address when defense costs are paid before a final ruling.
- Interrelated acts. Related wrongful acts may be treated as a single claim, sharing one limit and one policy period.
- Definitions. A narrow "professional services" definition in E&O can leave an activity outside the trigger.
Questions to ask your broker or underwriter
- How does the policy define wrongful act, and does it use the phrase actual or alleged?
- Does the definition include employment practices or fiduciary acts, or are those covered elsewhere?
- Are subsidiaries and outside directorships covered, and in what capacity?
- How does the policy define interrelated wrongful acts?
- Does the policy advance defense costs before a final adjudication, and when can the insurer reserve rights?
- What is the retroactive date, and what notice of circumstances provisions apply?
Common mistakes
- Assuming conduct outside the insured's role is covered.
- Assuming D&O and E&O use the same definition.
- Not reporting related matters together, which can complicate which policy period applies.
- Ignoring a reservation of rights letter instead of asking what it means.
Why it matters for technology, AI, fintech and digital-asset companies
For a technology company, E&O coverage depends on how the services are described. If the policy definition does not match what the company actually sells, a claim can fall outside the trigger. Allegations about AI outputs or platform failures usually turn on that definition. See errors and omissions and directors and officers coverage.
Startups raise money, make public statements and ship products quickly, and each of those activities can produce allegations of misstatement, mismanagement or a failed service. AI companies may face claims that model outputs caused harm, while fintech and digital-asset companies may face allegations about how customer funds, custody or risks were described. Wrongful act wording determines which of these allegations can trigger a policy.

Frequently asked questions
What is a wrongful act in insurance?
A wrongful act is the actual or alleged error, omission, misstatement, or breach of duty that triggers coverage under a management or professional liability policy. The exact definition is written into each policy and varies by coverage type.
Does a wrongful act have to be proven for coverage?
Generally no. Many policies use the phrase actual or alleged, so an allegation can trigger a claim and a defense obligation. Whether damages are ultimately covered depends on the outcome, the policy terms, and exclusions such as those for intentional misconduct.
Are intentional acts wrongful acts?
They can be alleged, but policies typically exclude deliberate fraud, dishonesty, and criminal conduct. Many policies still advance defense costs until a final adjudication, subject to the wording. Review the conduct exclusion and how it is triggered, such as by final judgment.
What is an interrelated wrongful act?
It is a set of wrongful acts that are logically or causally connected. Many policies treat them as a single claim first made when the earliest was made, which can mean one limit and one policy period apply. The definition and its effect are in the policy wording.
What is an example of a wrongful act?
In D&O, examples include an alleged misstatement to investors or a breach of fiduciary duty by a director. In E&O, examples include an alleged error in delivering a software service. The policy wording defines what counts.
What is the difference between a wrongful act and a claim?
A wrongful act is the alleged conduct, such as an error or breach of duty. A claim is the demand, suit or proceeding that arises from it. Coverage generally requires both a wrongful act and a claim within the policy terms.
Who is covered for a wrongful act under a D&O policy?
Typically directors and officers, and often other employees, for acts in their insured capacity. Entity coverage may also protect the company for certain claims, depending on the form.
What happens if the wrongful act occurred before the policy started?
It depends on the retroactive date and any prior knowledge conditions. Many claims-made policies cover only acts on or after the retroactive date, and exclude matters the insured knew about when applying.
