In Regus v. Schartkoff (1957) 156 Cal. App. 2d 382, there was an appeal from a judgment of dismissal following the sustaining of a demurrer. The complaint alleged that the claims adjuster for the insurer was the agent of the insureds. The opinion assumed without discussion that the insureds might be estopped under these circumstances, but held that the plaintiffs had failed to bring the action within a reasonable time after the estoppel expired. ( Id. at p. 387.)
