Ask a lawyer what their malpractice policy covers and they’ll name the limit. Ask them their retroactive date and most will need to look it up. Yet in a claim, the retro date is often the first thing that matters — it decides whether the policy responds at all.
The short answer
Your retroactive date (or prior acts date) is the earliest date of work your claims-made policy will cover. A claim filed today for work done before that date isn’t covered — by anyone. The date is set when you first buy coverage and carried forward at each renewal or carrier change, as long as coverage stays continuous. The two events that destroy it: a lapse in coverage, and a new policy issued with a fresh retro date. Both are silent — nothing feels different until a claim reaches back and finds nothing there.
How the retro date actually works
Claims-made coverage has two clocks. The policy period decides when a claim can be made; the retro date decides how far back the covered work extends. A lawyer insured continuously since 2015 has a 2015 retro date on a 2026 policy — eleven years of practice under today’s limits. That accumulated history is the real asset you’re paying premium on, and it’s why year-one policies are cheap: there’s almost no history to insure yet.
The three ways lawyers lose it
1. The lapse. Miss a renewal — cash-flow crunch, an application that stalls, a firm dissolution handled loosely — and continuity breaks. Reinstating coverage later usually means a new retro date: your history is gone, not suspended.
2. The cheap switch. A new carrier quotes a number hundreds of dollars lower — because the quote carries a current retro date instead of matching your old one. The discount is real; it’s buying less. Always compare retro dates before comparing premiums.
3. The move handled wrong. Changing firms? Your protection should continue via the new firm’s policy endorsing your original prior-acts date. Relying on your old firm to keep renewing its policy — forever, on your behalf, after you’ve left — is hope, not coverage. (When you actually need tail instead.)
Questions to ask before signing anything
- What retroactive date will appear on the new policy — matched to my current one, in writing?
- Does the quote provide full prior acts or a specific date? (“Full prior acts” — no retro limitation — is the strongest form.)
- If I’m joining your firm: will I be endorsed with my original date?
- If we’re switching carriers: show me the retro date on the binder, not the proposal.
This is precisely the review a specialist does before anything binds — it takes minutes and it’s included in every LawPAK suite. If you’re contemplating any policy change, have an advisor check your continuity first. It’s the cheapest insurance decision you’ll ever make.
FAQ
What is a retroactive date in malpractice insurance?
The earliest date of professional work your claims-made policy covers. Claims arising from work before that date aren’t covered regardless of when they’re filed.
What resets a retroactive date?
A lapse in continuous coverage, or accepting a new policy written with a new (later) retro date — common in bargain quotes.
What is full prior acts coverage?
A policy with no retroactive limitation — all your past professional work is covered for claims made during the policy period. It’s the strongest continuity position.
Does switching carriers reset my prior acts?
It shouldn’t — a properly placed replacement policy matches your existing retro date. Confirm it on the binder before the old policy ends.
