How many days must an insurer provide written notice before cancelling a policy for nonpayment of premium?

In California, if an insurer chooses to cancel a policy due to nonpayment of premium, they are required to provide a written notice at least 10 days prior to the cancellation. This requirement is in place to ensure that policyholders have adequate time to make the necessary payments or address any issues that may have led to the nonpayment. It emphasizes the importance of giving policyholders a chance to rectify their situation before the termination of their coverage, which is a critical factor in maintaining customer trust and ensuring clear communication from insurance providers. The 10-day notice period reflects the balance between the insurer's need to manage risk and the policyholder's right to be informed about their coverage status.
