Ins. Code, § 10173.2

When a policy of life insurance is, after the effective date of this section, assigned in writing as security for an indebtedness, the insurer shall, in any case in which it has received written notice of the name and address of the assignee, mail to the assignee a written notice, postage prepaid and addressed to the assignee’s address filed with the insurer, not less than 30 days prior to the final lapse of the policy, each time the policy owner has failed or refused to transmit a premium payment to the insurer before the commencement of the policy’s grace period or before the notice is mailed. The insurer shall give that notice to the assignee in the proper case while the assignment remains in effect, unless the assignee has notified the insurer in writing that the notice is waived. The insurer shall be permitted to charge the policy owner directly or against the policy the reasonable cost of complying with this section, but in no event to exceed two dollars and fifty cents ($2.50) for each notice.

As used in this section, “final lapse of the policy” means the date after which the policy will not be reinstated by the insurer without requiring evidence of insurability or written application.
