Texas Estates Code - EST § 113.208. Liability for Payment from Convenience Account

(a) A financial institution is completely released from liability for a payment made from a convenience account before the financial institution receives notice in writing signed by a party not to make the payment in accordance with the terms of the account. After receipt of the notice from a party, the financial institution may require a party to approve any further payments from the account.

(b) A financial institution that makes a payment of the sums on deposit in a convenience account to a convenience signer after the death of the last surviving party, but before the financial institution receives written notice of the last surviving party's death, is completely released from liability for the payment.

(c) A financial institution that makes a payment of the sums on deposit in a convenience account to the personal representative of the deceased last surviving party's estate after the death of the last surviving party, but before a court order prohibiting payment is served on the financial institution, is, to the extent of the payment, released from liability to any person claiming a right to the funds. The personal representative's receipt of the funds is a complete release and discharge of the financial institution.
