If your professional liability policy has an agreed-upon retroactive date or full prior-acts coverage, biBerk may help cover the costs associated with claims that are filed after coverage begins even if the error, unfulfilled duty, or negligent act happened before coverage was effective. For example, let’s say your professional liability policy began on June 30, with a retroactive date of January 1. On July 15, a former client claims you made a mistake on their taxes in March, which you were unaware of when you purchased the policy. Since the occurrence causing the claim took place during the retroactive coverage period (between January 1 and June 29) and the claim is made during your regular coverage period, you’ll likely be covered. With full prior-acts coverage, you’ll have professional liability coverage for all services provided before the policy period. If you haven't bought a policy before, claims will only be covered if the error, promise, or negligent act happens during the policy period.
