§560:6-104 Right of survivorship. (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 intention at the time the account is created. If there are two or more surviving parties, their respective ownerships during lifetime shall be in proportion to their previous ownership interests under section 560:6-103 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 payable-on-death account,
(c) If the account is a trust account,
(d) 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 decedent's estate.
(e) A right of survivorship arising from the express terms of the account or under this section, or a beneficiary designation in a trust account, or a payable-on-death payee designation, cannot be changed by will. [L 1976, c 200, pt of §1; gen ch 1985]
