Any trust account may be paid, on request, to any trustee. Unless the credit union has received written notice that the beneficiary has a vested interest not dependent upon the beneficiary surviving the trustee, payment may be made to the personal representative or heirs of a deceased trustee if proof of death is presented to the credit union showing that the decedent survived all other persons named on the account as either trustee or beneficiary. Payment may be made, on request, to the beneficiary upon presentation to the credit union of proof of death showing that the beneficiary or beneficiaries survived all persons named as trustees.
