Prior Acts coverage refers to how far back in time your professional liability (E&O) insurance policy covers you for services you rendered to clients.
The Prior Acts date is the inception (first) date of uninterrupted coverage. A policyholder needs to maintain continuous Errors and Omissions coverage from that date — and be sure the current policy covers ALL services the policyholder has ever been involved with. With continuous E&O coverage for all the types of services you’ve ever been involved with, the E&O policy in place at the time the incident is reported would be responsible for paying any covered claims.
