Ins. Code, § 10382

No alteration of any written application for any disability policy shall be made by any person other than the applicant without his written consent except that insertions may be made by the insurer, for administrative purposes only, in such manner as to indicate clearly that such insertions are not to be ascribed to the applicant. The making of any other alteration without the consent of the applicant is a misdemeanor. If such alteration is made by any officer of the insurer, or by any employee of the insurer with the insurer’s knowledge or consent, such alteration is deemed to be performed by the insurer issuing the policy upon such altered application.
