Cal. Bus. & Prof. Code § 10158

When a real estate license is issued to a corporation, if it desires any of its officers other than the officer designated by it pursuant to Section 10211, to act under its license as a real estate broker, it shall procure an additional license to retain each of those additional officers. In the event of death or incapacity of a sole designated broker-officer, a corporation may operate as a licensee without interruption under its existing license if notice of the death or incapacity and an application for a new designated officer is filed with the department before midnight of the 10th business day after the event.
