Subject to Section 5040: (a) Sums remaining on deposit at the death of a party to a joint account belong to the surviving party or parties as against the estate of the decedent unless there is clear and convincing evidence of a different intent. If there are two or more surviving parties, their respective ownerships during lifetime are in proportion to their previous ownership interests under Section 5301 augmented by an equal share for each survivor of any interest the decedent may have owned in the account immediately before the decedent’s death; and the right of survivorship continues between the surviving parties. (b) If the account is a P.O.D. account: (1) On death of one of two or more parties, the rights to any sums remaining on deposit are governed by subdivision (a). (2) On death of the sole party or of the survivor of two or more parties, (A) 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 party, (B) if two or more P.O.D. payees survive, any sums remaining on deposit belong to them in equal and undivided shares unless the terms of the account or deposit agreement expressly provide for different shares, and (C) 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. (c) If the account is a Totten trust account: (1) On death of one of two or more trustees, the rights to any sums remaining on deposit are governed by subdivision (a). (2) On death of the sole trustee or the survivor of two or more trustees, (A) 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 different intent, (B) if two or more beneficiaries survive, any sums remaining on deposit belong to them in equal and undivided shares unless the terms of the account or deposit agreement expressly provide for different shares, and (C) if two or more beneficiaries survive, there is no right of survivorship in event of death of any beneficiary thereafter unless the terms of the account or deposit agreement expressly provide for survivorship between them. (d) In other cases, the death of any party to a multiparty account has no effect on beneficial ownership of the account other than to transfer the rights of the decedent as part of the decedent’s estate. (e) A right of survivorship arising from the express terms of the account or under this section, a beneficiary designation in a Totten trust account, or a P.O.D. payee designation, cannot be changed by will.
