New Jersey Statutes Title 26. Health and Vital Statistics 26 § 2H-58

(1) An adult who has mental capacity, including, but not limited to, a declarant's spouse, partner in a civil union as defined in section 2 of P.L.2006, c. 103 (C.37:1-29), domestic partner as defined in section 3 of P.L.2003, c. 246 (C.26:8A-3), adult child, parent, or other family member, friend, religious or spiritual advisor, or other person of the declarant's choosing, may be designated as a health care representative.

(2) An operator, administrator, or employee of a health care institution in which the declarant is a patient or resident shall not serve as the declarant's health care representative unless the operator, administrator, or employee is related to the declarant by blood, marriage, domestic partnership, civil union, or adoption.

This restriction does not apply to a physician, if the physician does not serve as the patient's attending physician and the patient's health care representative at the same time.

(3) A declarant may designate one or more alternate health care representatives, listed in order of priority.  In the event the primary designee is unavailable, unable, or unwilling to serve as health care representative, or is disqualified from such service pursuant to this section or any other law, the next designated alternate shall serve as health care representative.  In the event the primary designee subsequently becomes available and able to serve as health care representative, the primary designee may, insofar as then practicable, serve as health care representative.

(4) A declarant may direct the health care representative to consult with specified individuals, including alternate designees, family members, and friends, in the course of the decision making process.

(5) A declarant shall state the limitations, if any, to be placed upon the authority of the health care representative including the limitations, if any, which may be applicable if the declarant is pregnant.
