New Jersey Statutes Title 3B. Administration of Estates Decedents and Others 3B § 28-3

a. During life every married individual shall be entitled to joint possession with his spouse of any real property which they occupy jointly as their principal matrimonial residence and to which neither dower nor curtesy applies. One who acquires an estate or interest in real property from an individual whose spouse is entitled to joint possession thereof does so subject to such right of possession, unless such right of possession has been released, extinguished or subordinated by such spouse or has been terminated by order or judgment of a court of competent jurisdiction or otherwise.

b. Nothing contained herein shall be construed to prevent the release, subordination or extinguishment of the right of joint possession by either spouse, by premarital agreement, separation agreement or other written instrument.

c. The right of joint possession shall be extinguished by the consent of both parties, by the death of either spouse, by judgment of divorce, separation or annulment, by other order or judgment which extinguishes same, or by voluntary abandonment of the principal matrimonial residence.
