Tail Coverage When a Practice Closes

A claims-made policy protects against claims first made and reported while it is in force. When it ends, that protection ends with it, and it ends for every year of work the professional ever performed, not merely for the year just closed. The extended reporting endorsement exists to address that outcome. It is bought at the end of the relationship with the insurer, on a short timetable, and it is the last opportunity to insure a career's worth of completed work.

What the endorsement actually does

The endorsement extends the time within which a claim may be reported. It does not extend the policy period, does not cover work performed after termination, and in its standard form does not add a new limit. A claim reported during the extension must still arise from work performed before termination and after the retroactive date. What the endorsement removes is the requirement that the claim be made while the policy was in force.

Understanding that the limit is shared matters for pricing decisions. A professional buying a long extension is buying reporting time, not additional capacity, and if the aggregate limit has been consumed the extension preserves nothing. Some insurers offer a reinstated limit for the extension period at a substantially higher premium. That option is negotiated at inception or renewal, since after termination the insured has no leverage and often no alternative market.

The window to elect it

The right to purchase is time-limited and the limit is short. Policies commonly require written election within thirty or sixty days after termination, together with payment of the endorsement premium within the same period or shortly after. The window runs from termination of the policy however it occurred, including cancellation and non-renewal by either side. It does not run from the date the practice actually closed, which can be considerably earlier or later.

The failure pattern is consistent and avoidable. A practice winds down over months, the policy lapses at renewal during that process, and the election period expires unnoticed while the professional is occupied with transferring files and notifying clients. Those closure obligations are themselves regulated, requiring steps reasonably practicable to protect client interests and, where a practice is sold, notice to affected clients. Adding the insurance election to that checklist costs nothing and cannot be done retrospectively.

Partial closures create the same problem in a less visible form. A professional who leaves a firm is covered for work done there only if the firm maintains its own policy or buys run-off cover for the entity, since the departing individual's new policy will not usually reach back to a predecessor firm. A firm that dissolves leaves every former partner exposed unless someone pays for the entity's extension. Responsibility for that payment is a term of the dissolution agreement, and it is one of the terms most often left unaddressed.

Pricing and the alternatives

Endorsement premium is customarily quoted as a percentage of the expiring annual premium, rising with the length of the reporting window. A one-year extension sits well below the annual premium; a multi-year or unlimited extension commonly exceeds it, sometimes by a substantial multiple. The figure is set by the policy or by a schedule attached to it, so it can be established before it is needed rather than discovered at termination.

The principal alternative is prior acts cover under a successor policy. A professional joining another firm may find that the firm's policy will accept the earlier work if the retroactive date is set appropriately, which achieves the same protection at no separate cost. The arrangement must be confirmed in writing, because a policy that covers the individual for work performed at the firm does not necessarily cover work performed at a predecessor practice, and because the former entity may remain a defendant in its own right.

A third route, available mainly to entities, is a dedicated run-off policy naming the dissolved practice as insured for a fixed multi-year term. It behaves much like an endorsement but is underwritten separately and can carry its own limit. Availability narrows sharply once a wind-down is announced, and insurers price it against the practice's claims history and the nature of the work performed rather than against its former revenue. As with every other option, it must be arranged while the practice still has a policy in force.

Deciding how long a window to buy

The right length is a function of the limitation and repose regime governing the work. Where claims may be brought years after the engagement ends, a one-year reporting window closes long before the exposure does. The relevant periods are those described in when the limitation period starts to run, extended by any tolling, and capped by the outer bar that runs regardless of discovery. A window shorter than the outer bar leaves a period during which claims remain viable and cover does not exist.

Two further factors bear on the decision. Work with long-latency exposure, such as instruments that will not be relied on for years, argues for the longest available window. So does a practice whose clients are institutions with the resources and the record-keeping to bring a late claim. Against that, a professional whose engagements were short and whose files closed cleanly may reasonably buy less. Whatever length is chosen, the reporting mechanics remain those set out in claims-made insurance and the reporting trap, and the endorsement does nothing to relax them.
