Medical Power of Attorney in New Jersey: Proxy Directives, Living Wills, and What You Need

You're sitting in a pre-surgery consultation and the hospital asks whether you have someone authorized to make medical decisions if you can't speak for yourself. In New Jersey, the document that grants that authority isn't called a "medical power of attorney" — it's called an Advance Directive, and it works differently from the financial POA most people are familiar with.

How New Jersey Structures Medical Decision-Making Authority

New Jersey recognizes three types of advance directives under N.J.S.A. 26:2H-53 et seq.:

Proxy Directive — This is the functional equivalent of a medical power of attorney. It designates a "healthcare representative" who can make medical decisions on your behalf when you lose the capacity to communicate. This person can consent to or refuse treatment, choose providers, and access your medical records.

Instruction Directive (Living Will) — This outlines your specific wishes about life-sustaining treatment, mechanical ventilation, artificial nutrition, and other medical interventions under terminal or permanently unconscious conditions. It speaks for you when nobody else can.

Combined Directive — Executes both the proxy designation and specific medical instructions in a single document. This is what most estate planners recommend because it gives your healthcare representative clear guidance about your wishes while also granting them the flexibility to handle situations you didn't anticipate.

Execution Requirements

To create a legally binding advance directive in New Jersey:

• Sign and date the document while you are a competent adult (18 or older)
• Acknowledge before either a notary public, a New Jersey attorney, or two adult witnesses

This is a key difference from financial POAs, which require notarization. For healthcare directives, two witnesses are an acceptable alternative to a notary.

Who cannot serve as a witness or healthcare representative:

• Your attending physician
• Administrators or employees of a healthcare facility where you're receiving care (unless they're closely related by blood or marriage)
• The designated healthcare representative cannot be one of the two witnesses

Who Can Be Your Healthcare Representative

You can appoint any competent adult — a spouse, adult child, sibling, close friend, or any person you trust to follow your wishes under pressure. There are no residency requirements for the representative.

Important considerations when choosing:

• Pick someone who can handle conflict. End-of-life decisions often split families. Your representative needs to advocate for your documented wishes even when other family members disagree.
• Choose someone geographically accessible. Hospitals move fast during emergencies. A representative across the country may struggle to participate in real-time decisions.
• Name an alternate. If your primary representative is unavailable, an alternate ensures someone is always authorized.

One critical rule many people miss: if you appoint your spouse as healthcare representative and later divorce, that designation is automatically revoked under New Jersey law — unless the document explicitly states it survives divorce.

What a Healthcare Representative Can and Cannot Do

They can:

• Consent to or refuse medical treatment on your behalf
• Choose doctors, hospitals, and care facilities
• Access your medical records
• Make decisions about life-sustaining treatment consistent with your instruction directive

They cannot:

• Make financial decisions (that requires a separate financial power of attorney)
• Override a clearly documented instruction directive
• Authorize treatment you've explicitly refused in writing

Why You Need Both Documents

A financial power of attorney and a healthcare directive serve completely different functions under New Jersey law. Your financial agent cannot make medical decisions, and your healthcare representative cannot access your bank accounts.

Families who only execute one document often discover the gap during a crisis — the person managing mom's bills can't talk to her doctors, and the person making medical decisions can't pay the hospital.

Getting Your Documents in Order

The New Jersey Power of Attorney Kit includes both the financial durable power of attorney and the complete healthcare advance directive — proxy designation, instruction directive, and HIPAA authorization — with New Jersey-specific execution instructions and signing requirements.
