I agree that the bank attorney would be a great place to start. That's not to say that bank to bank, attorneys may interpret differently. Kansas also allows charities as beneficiaries, which are clearly not a "person", so it's not as cut and dry as saying a beneficiary must be a person. I was only speaking from previous experience with that same question, and here is the guidance I was going off.
What KSA 9-1215 states is that "As used in this section, "person" means any individual, individual or corporate fiduciary or nonprofit religious or charitable organization as defined by K.S.A. 79-4701, and amendments thereto."
My response was based on current KBA position, which is
"Because of the limitations on beneficiaries, a trust cannot be named as beneficiary of a POD account. The trustee, however, is an individual fiduciary, and can be named as beneficiary. Banks should simply identify the trustee as follows: "Trustee for the John Doe Family Trust" (do not need actual name, can just say "trustee"). As a practical matter, the trust will get the funds upon the owner's death, but the bank must jump through this technical documentation hoop."
Not naming a specific trustee allows for contingent trustees without the requirement to update POD contracts and account documentation
If you still need guidance, the KBA account documentation book (which was the source for this info) or the KBA itself are both great tools (along with your attorney).
