Prior acts coverage is a feature in claims-made E&O insurance that protects you from claims that arise during your current policy period but stem from work you did before the policy started. This coverage only applies to incidents that happened after your policy's retroactive date.
Think of prior acts coverage as a safety net for your past work. Without it, you'd only be covered for incidents that happen after your current policy begins, leaving a potentially dangerous gap in protection.
For example, if you provided advice to a client two years ago and they sue you today claiming that advice was flawed, prior acts coverage would protect you (assuming the incident occurred after your retroactive date).
In professional services, claims often emerge long after the work is completed. A tax filing error might not be discovered until an audit years later. A design flaw might only become apparent after a building is constructed.
This delay between service and claim makes prior acts coverage especially important for E&O insurance. Without it, professionals face significant exposure for past work.
Consider what happens when switching insurance carriers: if your new policy lacks prior acts coverage, you could be unprotected for all work done before the new policy started even if you've maintained continuous insurance.
The stakes are particularly high in fields with long-tail risks like legal services, accounting, and healthcare, where claims can surface years after services are provided.
Prior acts and tail coverage address different timing challenges in claims-made policies, but many professionals confuse these important protections.
Prior acts coverage looks backward, protecting you from claims made today for incidents that happened in the past. Tail coverage looks forward, allowing you to report claims in the future for incidents that happened while your policy was active.
Both are critical components of a complete risk management strategy. Without prior acts coverage, your past work remains exposed. Without tail coverage, you lose the ability to report claims after your policy ends.
The retroactive date is the earliest point from which your claims-made policy will cover incidents. This date appears on your policy declarations page and serves as a clear boundary: incidents before this date aren't covered, while those after it potentially are.
When you first purchase a claims-made policy, the retroactive date is typically set to the policy's start date. As you renew your policy or switch carriers, this date should remain unchanged—preserving your coverage for past work.
If your coverage lapses even briefly, your retroactive date may reset to the new policy's start date—effectively erasing protection for all work done before the lapse.
Finding your retroactive date is straightforward: look at your policy's declarations page or coverage summary. This date defines how far back your coverage extends.
When you receive new policy documents, always verify that this date matches your original policy start date (or your earliest continuous coverage date). If the date has changed or is missing, contact your broker immediately.
Coverage gaps occur when there's a break in your insurance protection. These gaps can happen when:
The consequences of these gaps can be severe: you may have no coverage for claims related to work done during or before the gap period. Always confirm continuous coverage when changing policies or carriers.
Policy renewal is a critical time to protect your retroactive date and coverage continuity. Start the renewal process early at least 60 days before expiration to avoid last-minute problems that could create gaps.
During renewal, carefully review your new policy documents to ensure the retroactive date remains unchanged. If you're switching carriers, confirm that your new policy includes prior acts coverage that maintains your original retroactive date.
Keep records of all policy documents, including declarations pages showing retroactive dates. These records provide proof of continuous coverage if questions arise later.
Tail coverage (also called an Extended Reporting Period or ERP) extends the time you have to report claims after your policy ends. Unlike prior acts coverage, which protects past work during an active policy, tail coverage allows you to report claims after your policy terminates.
This coverage becomes important in several specific situations:
When you retire or close your business, your E&O policy will eventually end, but your liability for past work doesn't. Tail coverage allows you to report claims that arise after your policy terminates.
The appropriate length of tail coverage depends on the statute of limitations for your profession and location. Some professionals need tail coverage for just a few years, while others may need it for a decade or more.
Without tail coverage, you could face uncovered claims during retirement potentially putting your personal assets at risk long after you've stopped practicing.
When changing insurance carriers, you face a critical decision: secure prior acts coverage from your new insurer or purchase tail coverage from your old one.
If your new policy includes prior acts coverage back to your original retroactive date, you may not need tail coverage. However, if your new policy excludes prior acts or sets a new retroactive date, tail coverage from your previous insurer becomes essential.
Always clarify these coverage details before terminating your existing policy. Once a policy ends, the option to purchase tail coverage may expire quickly.
Some professions face "long-tail" risk situations where claims may emerge many years after services are provided. These risks make tail coverage particularly important.
In these fields, errors may not become apparent for years or even decades. Tail coverage provides protection against these delayed claims, giving professionals peace of mind even after they've stopped practicing.
Full prior acts coverage means your policy covers all your past professional services without a specific retroactive date limitation. This coverage is the most comprehensive form of prior acts protection, but it's not without limitations.
Even with full prior acts coverage, most policies exclude:
These exclusions can create unexpected gaps even in policies with full prior acts endorsements. Understanding these limitations helps you identify potential vulnerabilities in your coverage.
When changing carriers, pay particular attention to how your new policy addresses prior acts. Some insurers may offer full prior acts coverage only if you've maintained continuous insurance with no coverage gaps.
Maintaining comprehensive E&O protection requires attention to detail and regular policy reviews. Here's how to ensure your coverage remains intact:
