Provisions in policies mandating that insurers are to provide advance notice of
cancellation or nonrenewal of a policy. Most commonly, the required
cancellation notice period is 30 days, although state amendatory endorsements
frequently extend this period to 60 days. Additionally, most policies require
that the insurer provide advance notice of nonrenewal with the notice
requirement ranging from 10 to 75 days depending on jurisdiction and
circumstances surrounding the nonrenewal.
