In First Western Bank & T. Co. v. Omizzolo (1959) 176 Cal. App. 2d 555, 1 Cal. Rptr. 758, a letter to decedent from her attorney at the time of her divorce from appellant was admissible evidence of the decedent's state of mind. The evidence was admitted to rebut appellant's argument that decedent's failure to change beneficiary on her retirement fund showed an intent to leave the fund to appellant. (176 Cal. App. 2d at p. 563.)
