N.J. Stat. § 17:16I-14: Effect of transfer by right of survivorship

Any transfers resulting from the application of section 5 are effective by reason of the account contracts involved and this act, and are not to be considered as testamentary. The right of any surviving party to a joint account, or of any beneficiary, or of any P.O.D. payee, to the sums on deposit on the death of any party to a multiple-party account maintained in any financial institution, shall not be denied, abridged or in anywise affected because such right has not been created by a writing executed in accordance with the laws of this State prescribing the requirements to effect a valid testamentary disposition of property.
