(a)
(1) Payment made pursuant to this subchapter in accordance with an agency account discharges the bank from all claims for amounts so paid, whether or not the payment is consistent with the beneficial ownership of the account as between parties, beneficiaries, or their successors.
(2) Payment may be made whether or not a party, beneficiary, or agent is disabled, incapacitated, or deceased when payment is requested, received, or made.
(b)
(1) Protection under this section does not extend to payments made after a bank has received written notice from a party, or from the personal representative, surviving spouse, or heir or devisee of a deceased party, to the effect that payments in accordance with the terms of the agency account should not be permitted and the bank has had a reasonable opportunity to act on it when payment is made.
(2) Unless the notice is withdrawn by the person giving it, the successor of any deceased party must concur in a request for payment if the bank is to be protected under this section.
(3) Unless a bank has been served with process in an action or proceeding, no other notice or other information shown to have been available to the bank affects its right to protection under this section.
(c) A bank that receives written notice pursuant to this section or otherwise that has reason to believe that a dispute exists as to the rights of the parties may refuse, without liability, to make payments in accordance with the terms of the agency account.
(d) Protection of a bank under this section does not affect the rights of parties in disputes between themselves or their successors concerning the beneficial ownership of sums on deposit in agency accounts or payments made from agency accounts.
