Prior Acts Coverage
Claims-made coverage for professional acts occurring before the current policy period but after the retroactive date, protecting past work.
What It Is
Prior acts coverage refers to the protection provided by a claims-made policy for acts, errors, or omissions that occurred before the current policy's inception date but after the retroactive date. It is the retrospective component of claims-made coverage that protects the insured against claims arising from past professional work.
Prior acts coverage is accumulated over time as the insured maintains continuous claims-made coverage. An insured who first purchases E&O in 2020 starts with zero prior acts (the retroactive date and policy inception are the same). By 2025, they have accumulated 5 years of prior acts coverage—the policy covers claims from acts going back to 2020.
The value of prior acts coverage increases over time and is one of the most significant barriers to switching claims-made carriers. A new carrier that will not match the existing retroactive date effectively strips away years of accumulated prior acts protection. This is why maintaining retroactive date continuity is critical.
Why It Matters for Brokers
Prior acts coverage represents a significant intangible asset for any professional firm. Years of accumulated prior acts protection cannot be easily replaced or recreated. Brokers must communicate the value of prior acts coverage to clients who are tempted to switch carriers for a small premium reduction—the potential loss of prior acts protection far outweighs marginal premium savings.
Real-World Example
A law firm has maintained E&O coverage continuously since 2012 with a retroactive date of 01/01/2012. They now have 13+ years of prior acts coverage. A malpractice claim filed in 2025 alleges an error in a 2014 transaction. Because the 2014 error is after the 2012 retroactive date, the current 2025 policy covers the claim. If the firm had switched carriers in 2020 and accepted a new retroactive date of 01/01/2020, the 2014 error would be permanently uninsured—falling in the gap between the old policy's expiration and the new policy's retroactive date.
Common Mistakes
- 1Not explaining the value of accumulated prior acts coverage to clients who want to switch carriers for premium savings.
- 2Failing to negotiate retroactive date matching when placing coverage with a new claims-made carrier.
- 3Not recognizing that purchasing a new claims-made policy with an inception-date retroactive provides zero prior acts protection—only going-forward coverage.
How brokerageaudit.com Handles This
brokerageaudit.com's Policy Checker calculates the years of accumulated prior acts coverage for each claims-made policy and displays this prominently. When a carrier change is proposed, the system models the impact on prior acts coverage and generates a comparison showing what would be lost with an advanced retroactive date versus what would be preserved with retroactive date continuity.
