Ins. Code, § 771.02

(a) When a lender or purchaser of a mortgage on real property has required and obtained a copy of the insurance policy covering that real property, it shall be responsible for providing a copy of that insurance policy or other evidence of insurance acceptable to the purchaser to a subsequent purchaser of the mortgage, servicing agent, or insurance tracking service with whom the lender or purchaser of the mortgage subsequently contracts. A copy of the policy or other evidence of insurance shall be provided so that the subsequent purchaser, servicing agent, or insurance tracking service may verify that the borrower has obtained or is maintaining insurance required by the mortgage. This section does not abrogate the responsibility of an insurer, agent, or broker to provide annually, if requested, a copy of the insurance policy directly to the lender or purchaser of the mortgage named as an additional loss payee or lienholder at an address provided by the lender or purchaser of the mortgage.

(b) A copy of the insurance policy or other evidence of insurance acceptable to the purchaser may be provided electronically to the subsequent purchaser of the mortgage, servicing agent, or insurance tracking service with whom the lender or purchaser of the mortgage subsequently contracts, if that party agrees to electronic service.
