California Code, Insurance Code - INS § 10295.8

(a) An applicant for an accelerated death benefit shall have the right to return the accelerated death benefit policy or certificate by first-class United States mail within 30 days of its delivery and to have the premium refunded if, after examination of the policy or certificate, the applicant is not satisfied for any reason. If the accelerated death benefit is purchased as an endorsement or rider at the same time as the base life insurance policy, then the endorsement or rider may be returned within 30 days. The underlying life insurance policy shall be otherwise subject to this code.

(b) The return of a life insurance policy or certificate that contains an accelerated death benefit, or the return of an accelerated death benefit rider or endorsement, shall void the life insurance policy, certificate, rider, or endorsement from the beginning, and the parties shall be in the same position as if no policy, certificate, rider, or endorsement had been issued. All premiums paid and any policy fee paid for the accelerated death benefit shall be fully refunded directly to the applicant by the insurer within 30 days after the policy, rider, endorsement, or certificate is returned.

(c) Policies, certificates, riders, or endorsements to which this section applies shall have a notice prominently printed, or attached thereto, stating in substance the conditions described in subdivisions (a) and (b).
