Medical power of attorney in New Jersey: how to sign one

Updated 2026-10-18

The short answer

In New Jersey, a medical power of attorney is a proxy directive naming a health care representative. You sign it before two adult witnesses or a notary or attorney, and your representative can't be a witness. New Jersey has no law listing who decides if you name nobody, so naming someone matters more here.

The question under every medical power of attorney is a simple one. If you can't speak for yourself, who talks to the doctor?

In New Jersey, the honest answer is that the law doesn't say unless you do. This page covers what the document is called, how to sign it, who can't witness it, how a living will fits in, and what happens if you name nobody. It is part of our guides to estate planning state by state. For the basics of the role, see what a medical power of attorney is.

What is it called in New Jersey?

New Jersey uses its own words. The umbrella document is an "advance directive for health care" (N.J.S.A. 26:2H-55).

  • The part that names a person is a proxy directive. The person you name is your health care representative.
  • The part that writes down your wishes is an instruction directive. Most people would call it a living will.

You can sign one, the other, or both together. Our post on advance directives explains the general idea.

How do I sign it?

You sign and date it (or someone signs at your direction). Then you choose one of two ways to make it valid (N.J.S.A. 26:2H-56):

  • Two adult witnesses, who attest that you are of sound mind and free of duress and undue influence, or
  • Acknowledgment before a notary public, an attorney at law, or another person authorized to administer oaths.

The person you name as your health care representative can't be one of your witnesses. A neighbor and a friend from church, or a notary at your bank, work well.

New Jersey's statute doesn't include an official form. Any document that meets the signing rules works.

That is different from New Jersey's financial power of attorney, which must be acknowledged before a notary or similar officer. Our New Jersey power of attorney guide covers that document.

Who can I name?

Almost any adult with capacity: a spouse, civil union or domestic partner, adult child, parent, other relative or friend (N.J.S.A. 26:2H-58).

One group is ruled out. An operator, administrator or employee of the health care facility where you are a patient or resident can't serve, unless related to you by blood, marriage, domestic partnership, civil union or adoption. A physician can serve if they are not also your attending physician.

You can name alternates in order of priority. Do that. If your first choice is traveling or sick, the second steps in without anyone going to court. Our post on having a backup in every role explains why.

Your representative is a fiduciary: legally required to act in your interest and follow what you wrote.

Do I need a living will too?

Many people sign both. The proxy directive names a person. The instruction directive tells that person what you want, so they aren't guessing.

In New Jersey, an instruction directive can state your general treatment philosophy, your specific wishes about any care including life-sustaining treatment, or both (N.J.S.A. 26:2H-58). It is signed the same way: two adult witnesses, or a notary or attorney. It can be separate or attached to your proxy directive.

Our post on health care power of attorney vs living will explains how the two work together, and treatment preferences helps you think through what to write.

Who decides if I haven't named anyone?

Here New Jersey differs from most states. It has no default decision-maker statute, meaning no law that lists family members in order to make medical decisions for you.

The Advance Directives for Health Care Act says that not having an advance directive creates no presumption about your wishes. It also says the Act doesn't apply to people who haven't signed one (N.J.S.A. 26:2H-74). New Jersey's POLST law mentions a "patient's representative" designated by the patient "or otherwise authorized under law," without saying who that is (N.J.S.A. 26:2H-131).

SituationWho decides under New Jersey statute
You named a health care representative in a proxy directiveYour representative, then your alternates in the order you listed
You named nobodyNo statute sets a family order; a spouse, adult child or friend has no listed rank
A close friend who knows your wishesCan serve if you name them; no statute gives them a place otherwise

So whether a spouse, a grown son or your oldest friend may speak for you is not set by statute. Whatever happens in that gap, it isn't something you chose. A proxy directive is.

Most other states do have a list. Our post on medical decisions without a power of attorney compares them, and the 50-state guide to default decision-makers has each state. To see who would speak for you where you live, try our who decides for me tool.

Here is a typical case, a composite. Eleanor is 73, widowed, and lives in Princeton. Her son lives in California. Her friend Grace goes to every appointment with her and knows exactly what she would want. Eleanor names Grace as her health care representative and her son as the alternate, with two neighbors as witnesses.

How do I choose my representative?

Once the signing is done, the practical questions matter most. Is the person willing? Can they get to the hospital? Will they follow your wishes even when they'd choose differently?

A short checklist:

  • They know what you want, because you've told them.
  • They can stay calm in a hospital hallway and ask questions.
  • They live close enough, or can travel when needed.
  • You've named an alternate in case they can't.

Our post on how to choose a medical power of attorney has more questions to ask.

Some people would like a professional standing by, first or behind a friend. A Kinly membership includes a medical power of attorney written for your state, and you decide who comes first and who is the backup.

Common questions

Does a medical power of attorney need to be notarized in New Jersey?

No, not if you use witnesses. You can sign before two adult witnesses, or acknowledge it before a notary, an attorney or another officer authorized to administer oaths. Either way is valid.

Who can't witness my New Jersey advance directive?

The person you name as your health care representative can't be a witness. Witnesses must be adults who attest that you are of sound mind and free of duress and undue influence.

Who makes medical decisions in New Jersey if there's no advance directive?

No New Jersey statute sets a family order. The law says not having an advance directive creates no presumption about your wishes. Naming a health care representative is the way to decide this yourself.

Can a friend be my health care representative in New Jersey?

Yes. Any adult with capacity can serve, including a friend. The main exception is an employee or operator of the facility where you are a patient or resident, unless they are related to you.

Is there an official New Jersey form?

No form appears in the Advance Directives for Health Care Act. Any document that meets the signing rules is valid.
