Prior Acts Coverage Explained: Protecting Your Firm's History

Prior acts coverage, also known as retroactive coverage, is a provision in claims-made legal malpractice policies that extends protection to alleged errors or omissions that occurred before the current policy's inception date. Without it, a firm could face a gap in protection for work performed in prior years, even if the claim is first made during the current policy period.

How Claims-Made Policies Work

To understand prior acts coverage, you first need to understand the claims-made policy structure that dominates legal malpractice insurance. Unlike occurrence policies that cover events happening during the policy period regardless of when the claim is filed, claims-made policies cover claims first reported during the policy period for acts that occurred after a specified retroactive date. The retroactive date is the key to prior acts coverage.

The Retroactive Date

The retroactive date is the earliest date from which covered acts are protected under your policy. If your retroactive date is January 1, 2020, any alleged malpractice that occurred on or after that date is covered, provided the claim is first made and reported during the current policy period. An act that occurred on December 31, 2019 would not be covered. The ideal scenario for any firm is a retroactive date that goes back to the firm's inception or to when the individual attorney first began practicing, often referred to as full prior acts coverage.

Why Prior Acts Coverage Matters

Legal malpractice claims often arise years after the underlying legal work was performed. Statutes of limitations for malpractice vary by state but can extend three years or more from the date the client knew or should have known about the alleged error. In estate planning, real estate, and corporate work, errors may not surface for a decade or longer. Without prior acts coverage reaching back far enough, a firm could discover that the very claim it is facing falls into an unprotected gap.

Maintaining Continuous Coverage

The single most important thing a firm can do to preserve its prior acts protection is maintain continuous, uninterrupted malpractice coverage. When you switch carriers, your new insurer will typically honor your existing retroactive date as long as there has been no lapse in coverage. If coverage lapses, even briefly, the new carrier may set a new retroactive date at the new policy's inception, effectively erasing years of prior acts protection.

Negotiating Prior Acts With a New Carrier

When shopping for a new policy or switching carriers, always confirm that the new carrier will match your existing retroactive date. Provide the new insurer with your current declarations page showing the retroactive date and a complete claims history. Some carriers may attempt to set a later retroactive date if they perceive elevated risk in the firm's history; this is a negotiation point where an experienced broker can add significant value.

Prior Acts and Firm Changes

Prior acts coverage becomes particularly important during firm transitions such as mergers, dissolutions, and partner departures. When firms merge, the surviving entity needs to ensure that acts performed by both predecessor firms are covered. When a firm dissolves, attorneys joining new firms need to verify that their prior acts are protected either through tail coverage on the old policy or prior acts coverage on the new policy.

Understanding and protecting your retroactive date is one of the most consequential insurance decisions a law firm can make. Review your declarations page annually and discuss your retroactive date with your broker at every renewal.
