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.
