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

This bill requires insurers to send written notices of cancellation or nonrenewal for auto and homeowners insurance policies by certified mail with return receipt requested, plus regular mail with proof of mailing. Insurers must obtain a USPS date-stamped mailing receipt showing the policyholder's address and retain a copy of the notice. The notice is invalid if not sent this way, directly affecting policyholders who receive these notices and insurers who must comply. It amends existing insurance laws (P.L.1968, c.131 and c.158) to enforce this dual-mailing requirement.
