N.J. Stat. § 30:13-6
A nursing home resident may arrange for the resident's own discharge from a nursing home upon presentation of a written release and, if the resident is adjudicated incapacitated, upon the written consent of the resident's guardian. In this case, the nursing home is free from any responsibility for the resident upon the resident's release. When a nursing home wishes to transfer or discharge on a nonemergency basis a resident who has mental capacity or a resident who is adjudicated incapacitated, the nursing home may do so for medical reasons or for the person's welfare or for that of other residents upon receiving a written order from the attending physician, or for nonpayment, except as prohibited by Title XVIII or Title XIX of the Social Security Act, as amended, and the action shall be recorded in the resident's medical record. When a transfer or discharge on a nonemergency basis of a resident is requested by a nursing home, the resident or, in the case of a resident who is adjudicated incapacitated, the guardian, shall be given at least 30 days' advance notice of the transfer or discharge.
