Requires notice of cancellation or nonrenewal of automobile and homeowners insurance policies to be sent by certified mail, return receipt requested.

This bill requires insurance companies in New Jersey to send written notices of policy cancellation or nonrenewal (for both auto and homeowners insurance) via certified mail with a return receipt requested, plus regular mail with a date-stamped proof of mailing from the post office. It directly affects insurers (who must follow this process) and policyholders (who receive the notice). The key provision mandates that notices sent without certified mail and proof of mailing will not be valid, meaning the insurance policy remains in effect. This ensures policyholders receive verifiable notice of potential coverage changes.
