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

This bill requires New Jersey insurance companies to send written notices of policy cancellation or nonrenewal for auto and homeowners insurance via certified mail (with return receipt requested) and regular mail, including proof of mailing from the U.S. Postal Service. It directly affects homeowners and auto policyholders in New Jersey, as insurers must now follow this specific delivery method to make cancellations or nonrenewals effective. The key provision mandates that notices sent without certified mail plus proof of regular mail delivery will not take effect, keeping the policy active. This replaces prior rules that allowed different mailing methods for these notices. The law takes effect 60 days after enactment.
