Quick answer

Legal malpractice insurance is written on a claims-made basis. When you switch carriers, the new policy must honor your existing retroactive date. If the retroactive date is reset to inception, the firm instantly loses all protection for legal work performed in the past. Ask for the proposed retroactive date in writing, compare it to the current declarations page, and price tail coverage before the old policy expires. Background: prior acts coverage and retroactive dates.

The claims-made trap every law firm must avoid

Lawyers professional liability (LPL) insurance protects your reputation and assets, but it operates under a strict claims-made framework. The policy that handles a claim is the one active the day the claim is reported, not the policy that was active when the legal work was actually performed.

Because malpractice claims often emerge months or years after a case closes, any gap in your timeline can leave your historical liabilities completely exposed. When you evaluate a new carrier, three components decide whether the switch is safe:

  • The retroactive date. This is the baseline calendar date from which continuous coverage began. The new policy must match this date to preserve prior acts protection.
  • The danger of a reset. A cheaper premium that comes with a new retroactive date at policy inception is not a bargain. Every matter the firm closed before that date becomes uninsured.
  • Extended reporting periods, or tail coverage. If a carrier will not match your retroactive date, you need a tail from the expiring carrier to shield past work. Tail pricing is commonly a percentage of expiring premium and, bought on a permanent basis, can run to roughly one to three times annual premium depending on carrier and practice area. Get the number before the expiration date, not after.

The 60-day renewal timeline for competitive quotes

To get leverage with A-rated legal malpractice underwriters, structure the renewal around a disciplined timeline:

1. 60 days out. Pull the current policy declarations page to confirm the official retroactive date, and compile a five-year claims loss run history.

2. 30 days out. Compare quotes side by side. Require each carrier to confirm its proposed retroactive date in writing, so prior acts coverage stays intact.

3. Bind date. The new policy should start the exact same day the old one expires. Even a 24-hour gap breaks the continuous coverage chain.

Questions to ask before you sign

1. What retroactive date will you offer, and will you honor prior acts back to the firm's first claims-made policy?

2. Are there prior acts exclusions or known-acts wording in the form?

3. Is defense inside or outside the limit?

4. Does the policy name the firm entity, every attorney, and of counsel?

5. What is the tail premium if we leave in a future year?

6. How is work performed in other states the firm is admitted in handled?

If the answers are vague, ask for the declarations page and the exclusions section in writing. Verbal assurances do not survive a claim.

Claims history is not a reason to stay trapped

A firm with a claim or two can usually still move. Carriers price prior claims rather than rejecting the firm outright, and some markets specialize in firms with a history. What ends a renewal is not the claim itself but an application that does not disclose it, because a misrepresentation gives the carrier grounds to rescind.

Multi-state firms

Firms admitted in more than one state should schedule every state on the new policy, the same way the old one did. If the firm added an office or an attorney admitted elsewhere during the year, this is the moment to correct the schedule.
