Claims-Made Coverage Explained: Retroactive Dates and Tail Coverage for Attorneys

The Coverage Most Attorneys Don't Realize They Have

Lawyers professional liability is almost always written on a claims-made basis. That means the policy that responds to a claim is the one in force when the claim is made — not the one in force when the work was performed.

This is different from occurrence-based coverage (like most general liability), and the difference creates traps that catch attorneys at predictable moments: changing firms, retiring, or switching carriers. Understanding three terms — policy period, retroactive date, and tail coverage — prevents nearly all of them.

The Three Terms That Matter

Policy Period

The window during which a claim must be made and reported for the policy to respond. A claim arising from 2022 work can hit your 2027 policy — and it's the 2027 policy that responds, provided the right conditions below are met.

Retroactive Date (Prior Acts Date)

The date that separates covered past work from uncovered past work. Your policy covers claims arising from work performed after the retro date. If your retro date is continuous back to 2015, your 2015-and-later work is protected. If it resets to this year, everything before is exposed.

The single most important rule of claims-made coverage: never let your retroactive date reset. A reset quietly converts a decade of practice into uninsured history.

Tail Coverage (Extended Reporting Period)

An endorsement that keeps a expired claims-made policy alive for claims reported later, arising from work done during the policy period. Tails commonly run one year to unlimited, and typically cost a multiple of the final annual premium. You need one when your claims-made policy ends and no successor policy picks up prior acts — the classic cases being retirement and leaving a firm whose policy you weren't an insured under.

Where Attorneys Actually Get Burned

Moving between firms. You're covered as an attorney under Firm A's policy. You join Firm B. Claims from your Firm A work now need to be picked up by Firm B's policy (with your prior acts honored) or a tail on Firm A's policy. If neither happens, your past work is uninsured from your first day at the new firm.

Switching carriers at renewal. The new carrier must provide a retroactive date matching your continuity. If a quote comes back with a new retro date, the "cheaper" premium reflects less coverage — prior acts are being excluded.

Retiring or winding down. The last policy in force is the last coverage you'll ever have unless you buy a tail. Claims from your career can surface years after your last client. Retirement without tail coverage is the most common catastrophic gap we see.

Letting a policy lapse "temporarily." Even a short lapse can reset the retro date with a new carrier. As we cover in our article on repairing prior acts gaps, some carriers can restore continuity after a lapse — but it's underwriting-dependent and far easier to prevent.

The Practical Checklist

1. Know your retroactive date. It's on your policy declarations. If you can't find it, ask.

2. When changing firms, ask both firms' carriers in writing how your prior acts will be handled — before your last day.

3. When comparing quotes, compare retroactive dates, not just premiums. Same limit, different retro date = different coverage.

4. Before retiring, price tail coverage early. It's cheaper while your policy is active than negotiated after the fact.

5. Report potential claims before the policy ends. If you're aware of a circumstance that could become a claim, reporting it to your current carrier preserves coverage under that policy.
