New Jersey § 3a:2a-83

§ 3a:2a-83.

a. A surviving spouse, heir or devisee who intentionally kills the decedent is not

entitled to any benefits under a testate or intestate estate and the estate of decedent

passes as if the killer had predeceased the decedent. Property appointed by the will of the decedent to or for the benefit of the killer

passes as if the killer had predeceased the decedent. b. Any joint tenant who intentionally kills another joint tenant thereby effects a

severance of the interest of the decedent so that the share of the decedent passes

as his property and the killer has no rights by survivorship. This provision applies to joint tenancies and tenancies by the entirety, joint accounts

in banks, savings and loan associations, credit unions and other institutions, and

any other form of coownership with survivorship incidents. c. A named beneficiary of a bond, life insurance policy, or other contractual arrangement

who intentionally kills the principal obligee or the person upon whose life the policy

is issued is not entitled to any benefit under the bond, policy or other contractual

arrangement, and it becomes payable as though the killer had predeceased the decedent. d. Any other acquisition of property or interest by the killer shall be treated in

accordance with the principles of this section. e. A final judgment of conviction of intentional killing is conclusive for purposes

of this section. In the absence of a conviction of intentional killing the court may determine by

a preponderance of evidence whether the killing was intentional for purposes of this

section. f. This section does not affect the rights of any person who, before rights under

this section have been adjudicated, purchases from the killer for value and without

notice property which the killer would have acquired except for this section, but

the killer is liable for the amount of the proceeds or the value of the property. Any insurance company, bank, or other obligor making payment according to the terms

of its policy or obligation is not liable by reason of this section unless prior to

payment it has received at its home office or principal address written notice of

a claim under this section.
