The Job Is Finished.
The Claim May Not Be.

Professional liability, often called errors and omissions insurance or E&O, addresses covered claims alleging errors, omissions, or negligence in professional services. The Small Business Administration lists it separately from general liability, which addresses exposures such as bodily injury and property damage claims. The service provided and the policy definition still matter. [3]

Consultants and design professionals are useful examples. A contractor providing design or other professional services may also have a professional-liability question, but having a contractor's license does not by itself establish what professional services a policy insures. Nor should every contractor assume this is the trigger used by every policy in the business's insurance programme.

Claims-made and occurrence describe coverage triggers; they are not two names for a coverage limit. In an occurrence form, the relevant covered occurrence or event must fall within the policy period. A claim may arrive later, subject to all other policy terms, including notice requirements. In a claims-made form, the first claim generally must fall within the specified period, with reporting governed by the actual wording. [1] [2]

A claims-made-and-reported form explicitly makes both the first claim and the report to the insurer important to the coverage period. Some forms allow a specified reporting window after expiry. Others have different notice provisions. The American Bar Association's professional-liability guide explains this distinction in its discussion of lawyers' policies. It is a reason to read your form—not to assume a universal reporting grace period. [2]

These dates do not decide coverage on their own. The insured business, covered services, exclusions, and any rules for related claims also require review. But recording them makes it much easier to ask the right question promptly.

Consider a second hypothetical: an alleged error occurred in June 2025. A replacement professional-liability policy begins in January 2026. The client first makes a demand in October 2026.

If the new policy has a January 2026 retroactive date, the older work may be outside its reach. If the old policy ended before the demand, the fact that it was active in June 2025 does not by itself establish protection for the later claim under a claims-made trigger. [1] [2]

Prior acts coverage addresses eligible work performed before the current policy began, subject to the policy's boundaries. It is sometimes described as “nose” coverage. Texas's insurance regulator explains prior acts and tail coverage as possible ways to address continuity when changing claims-made medical-liability insurers. That shopping guide concerns Texas medical coverage; its particular laws and pricing are not rules for a Florida consultant. [5]

For a business changing insurers, ask whether the offered policy preserves the intended retroactive date and insures the relevant earlier services and entity. The date alone does not prove that all old work follows you. The American Bar Association's guide illustrates how work performed for a former firm may be outside a new firm's insurance despite the professional continuing in the same career. [2]

Do not describe a problem as unknown if a demand or a circumstance suggesting a claim is already known. Applications and exclusions may address prior knowledge, and reporting provisions may offer a way to notify the current insurer of a potential claim. The actual wording determines whether such notice is available and sufficient. A historical Hiscox specimen demonstrates that these provisions can require specific details and insurer acceptance; it is not a description of every current policy. [6]

An extended reporting period, or ERP, is commonly called tail coverage. Subject to its terms, it permits eligible claims involving earlier covered work to be made or reported after a claims-made policy ends. It does not mean the old policy continues to insure new professional work performed after its termination. [2] [7]

That distinction matters when someone stops taking large projects but still accepts small assignments. A tail for earlier work is not automatically ongoing professional-liability insurance for those new assignments. [2]

Also distinguish two different provisions that can appear after expiry. A short automatic reporting extension may only allow additional time to report a claim already made during the policy period. An optional ERP may permit certain later first-made claims arising from earlier work. The names can sound similar while the permissions differ. [2]

Eligibility, election deadlines, payment deadlines, and duration vary. Some policies have limited automatic provisions. Some offer an optional extension for an additional premium, with conditions. Do not wait for a claim before checking whether the option is still available. The ABA guide notes that the opportunity to elect an extension can lapse if the policy's deadline is missed. [2]

A tail can extend time without replenishing the insurance limit. As an example, the historical Hiscox specimen states that its optional ERP uses the remaining limits of the cancelled or nonrenewed policy and does not create a separate additional limit. Other issued forms must be checked individually. [6]

For that reason, ask two separate questions: “How long can an eligible claim be reported?” and “What limit remains available, and how do defence costs affect it?”

Our earlier note, The Lawsuit Does Not Stop at Your Policy Limit, follows liability amounts and coverage layers. This note follows timing. A large limit does not correct a missed reporting condition, and an extended reporting period does not automatically increase the amount available.

An insurance ERP is also not a legal extension of a claimant's time to sue. Legal filing deadlines and insurance reporting requirements are separate questions. Obtain appropriate legal advice when a demand or proceeding raises those issues.

Retirement, a sale, a merger, or simply deciding to stop providing a service can change the insurance arrangement. Completing the last project does not tell you which policy will handle a later allegation about that work. The ABA's guide discusses precisely these transitions for law firms and individual lawyers; the applicable options depend on the actual business and policy. [2]

Before cancelling, identify who performed the old work, which entity is insured, and who will receive future demands. Review whether ongoing insurance includes the earlier services or whether an ERP is appropriate and available. Keep access to the old issued policies and endorsements, not just a certificate.

A certificate is useful evidence, but it is not the document that defines prior acts or creates an ERP. The Certificate Says Insured. The Endorsement Decides What That Means. explains why the controlling documents matter.

A business may want to resolve a complaint quietly before involving anyone else. With a claims-made policy, that instinct must not postpone notice required by the policy. Travelers' design-professionals guide recommends reporting as soon as the business becomes aware of a claim and letting the insurer evaluate it. It warns that delayed reporting may put all or part of the claim outside coverage. [4]

Preserve the original demand and receipt details. Keep the relevant engagement agreement and project communications available. Follow the policy's notice instructions, involve the agent promptly, and obtain acknowledgement through the required channel. A conversation about notice is not a promise that the insurer will accept coverage.

Check any notice-of-circumstances provision before renewal if a problem has emerged but no formal claim has been made. Do not assume a vague warning or a general list of unhappy clients is sufficient. The historical Hiscox specimen, for example, calls for details about the potential claimant, alleged act, dates, and other information. [6]

Use this checklist before renewal, switching insurers, or ending a service. A checked item means you have located an answer in the current documents—not that a future claim is guaranteed to be covered.
