Section 705.06 - Protection of financial institutions(1) In accordance with the terms of an account, and subject to this subchapter, ch. 112 and the duties prescribed for personal representatives in ch. 72 and unless otherwise ordered by a court of competent jurisdiction: (a) A financial institution may on request pay any sums on deposit in the account to any party or agent; and the financial institution shall not be required to look into the source of funds received for deposit or the proposed application of any funds withdrawn or requested to be withdrawn.(b) Any sums in a joint account may be paid, on request, to any party without regard to whether any other party is under legal disability or is deceased at the time the payment is requested.(c) Any sums in a P.O.D. account may be paid, on request, to the P.O.D. beneficiary upon presentation to the financial institution of proof of death showing that the P.O.D. beneficiary survived all persons named as original payees of the account. If more than one P.O.D. beneficiary is named and at least one of them is predeceased, sums in the account may be paid to the surviving P.O.D. beneficiary or beneficiaries upon presentation of proof of death of the other beneficiary, without regard to claims by the issue of a predeceased beneficiary under s. 705.04(2) (d). If none of the named beneficiaries survive, the sums in the account may be paid to the estate of the deceased sole owner or the estate of the owner who was the last to die of multiple owners, without regard to claims by the issue of a predeceased beneficiary under s. 705.04(2) (d). If the P.O.D. account is a marital account, this paragraph applies only to the 50 percent of the account not owned by the surviving spouse named as a party on the account.(d) Any sums in a marital account may be paid, on request, to either party without regard to whether the other party is under legal disability or is deceased, unless the financial institution receives actual notice that the other party is deceased. After receipt of actual notice of the death of one party to a marital account, the financial institution may pay on request not more than 50 percent of the sums on deposit to the surviving party, and 50 percent of that amount to the personal representative of the deceased party or if applicable to any P.O.D. beneficiary of the deceased party's interest, unless before payment is made the financial institution receives a verified statement under s. 865.201 or a certified copy of a certificate or recorded application concerning survivorship rights under s. 867.046, in which case the financial institution shall make payment as provided in that document.(2) Payment made under this subchapter discharges the financial institution from all claims for amounts so withdrawn. If the institution has reason to believe that a dispute exists as to the rights of the parties to an account or their successors it may, but shall not be required to, refuse to pay funds in the account to any persons pending instructions from a court, or it may pay the proceeds to a court. An institution may but need not recognize the authority of an agent, other than one with continuing authority under s. 705.05(3), until it knows of the fact of death or adjudication of incompetence of all parties appointing such agent and has reasonable opportunity to act.(3) The protection provided by this section shall have no bearing on the rights of parties or their successors in disputes concerning the beneficial ownership of funds in or withdrawn from an account.1973 c. 291; 1983 a. 186; 1987 a. 27; 1989 a. 331; 2005 a. 216. A personal representative is not a "party" to an account held as a "joint account" by the decedent and another who survives; a bank who disburses the funds of the joint account to the personal representative is not entitled to immunity under this section.
