(2) If the account is a P.O.D. account:
(a) Upon the death of one of two or more original parties, the rights to any sums remaining on deposit are governed by subsection (1) of this section.
(b) Upon the death of the sole original party or the survivor of two or more original parties, any sums remaining on deposit belong to the P.O.D. payee or payees, if surviving, or to the survivor of them if one or more die before the original party. If two or more P.O.D. payees survive, there is no right of survivorship in the event of death of a P.O.D. payee thereafter unless the terms of the account or deposit agreement expressly provide for survivorship between them.
(3) If the account is a trust account:
(a) Upon the death of one of two or more trustees, the rights to any sums remaining on deposit are governed by subsection (1) of this section.
(b) Upon the death of the sole trustee or the survivor of two or more trustees, any sums remaining on deposit belong to the person or persons named as beneficiaries, if surviving, or to the survivor of them if one or more die before the trustee, unless there is clear and convincing evidence of a contrary intent. If two or more beneficiaries survive, there is no right of survivorship in the event of death of any beneficiary thereafter unless the terms of the account or deposit agreement expressly provide for survivorship between them.
(4) In other cases, the death of any party to a multiple-party account has no effect on beneficial ownership of the account, other than to transfer the rights of the decedent as part of the estate of the decedent.
(5) A right of survivorship arising under this section or from the express terms of the account, a beneficiary designation in a trust account or a P.O.D. payee designation cannot be changed by will.
(6) The rebuttable presumption under subsection (1) of this section may be overcome by evidence establishing that:
(a) The deceased party intended a different result; or
(b) The deceased party lacked capacity when the joint account was established.
(7) A credit union is not liable for distributing sums remaining on deposit at the death of a party to a joint account to a surviving party or parties in accordance with the account agreement unless, prior to distributing sums to a surviving party or parties:
(a) The credit union has received notice of an adverse claim under ORS 723.468; and
(b) The adverse claimant proceeds as required under ORS 723.468. [1999 c.185 §28; 2003 c.256 §2]
