In a trust case in which a wife agreed to hold funds in trust for her husband's elderly stepmother, and after her husband's death, the wife changed the form of the accounts and used the funds for her own purpose, the trial court's judgment in favor of wife-defendant under Code of Civil Procedure section 631.8 is reversed where, despite the form of the bank accounts, when clear and convincing evidence shows funds were transferred to an account owner to hold in an irrevocable trust for a third party beneficiary and the trustee repudiates the trust, a constructive trust may be imposed on the funds for the beneficiary's estate to prevent unjust enrichment.
