A healthcare proxy is one of the most important people you will ever designate — and one of the most overlooked documents in estate planning. Without one, your medical decisions fall to whoever the hospital can reach, in whatever order state law specifies, regardless of who actually knows and would honor your wishes.
What a Healthcare Proxy Does
Your healthcare proxy (also called a healthcare agent or healthcare power of attorney) is the person you designate to make medical decisions on your behalf when you are unable to make or communicate them yourself — due to incapacity, unconsciousness, severe illness, or cognitive impairment.
The proxy steps in to:
- Consent to or refuse medical treatments, procedures, and medications
- Make decisions about life-sustaining treatment
- Communicate your wishes to medical teams under pressure
- Handle situations your living will didn't specifically anticipate
- Access your medical records and speak with your healthcare providers
- Transfer you between facilities or discharge you from care
The proxy doesn't replace your wishes — they carry them out. Their job is to make decisions based on what you would have wanted, not what they would want for you.
Healthcare Proxy vs. Living Will: You Need Both
These documents work together:
- Your living will (advance directive) records your specific wishes in writing — what treatments you want or don't want under specific circumstances
- Your healthcare proxy is a person empowered to apply those wishes and make decisions in situations the document couldn't have anticipated
A living will without a proxy: your written wishes exist but may not be applied correctly in complex situations, and no one has clear authority to speak for you.
A proxy without a living will: a trusted person has authority but may not know your wishes clearly and may have to make guesses under pressure.
Both together: your wishes are documented, your proxy is informed, and there's a clear chain of authority for any situation that arises.
Choosing Your Healthcare Proxy
The ideal qualities
- Knows your values and wishes. Not just that you don't want "extraordinary measures" — the specific conversations you've had, the things you've said about how you want to live and die.
- Will honor your wishes, not substitute their own. The hardest part of being a proxy is sometimes allowing someone you love to die rather than demanding every possible intervention. The proxy must be able to do this.
- Can communicate clearly under pressure. Medical teams are busy and sometimes make assumptions. Your proxy may need to firmly and repeatedly state your position.
- Is accessible. Can be reached quickly in a crisis; can be physically present if needed.
- Is emotionally capable of the role. Not so overwhelmed by grief that they can't function; can hold steady in the moments when the decision is hardest.
The conversation you must have
Before naming someone, have a real conversation. Cover:
- Are you willing to take on this role?
- Here's what I want in various scenarios (quality of life thresholds, specific fears, what "living" means to me)
- Here's what I don't want — specific interventions, specific situations
- I need you to honor my wishes even if it's different from what you would choose for yourself
Many people choose a spouse or adult child. But closeness to the person doesn't mean the right person — sometimes the spouse will be too overwhelmed; sometimes an adult child who lives nearby and has a clear head is better. Be honest with yourself about who can carry this role.
How to Formalize the Designation
The healthcare proxy designation is part of your advance directive or healthcare power of attorney document. Requirements vary by state — most require the document to be signed and witnessed, with some states requiring notarization. An estate planning attorney can prepare the document as part of a complete estate plan; online services (Trust & Will, Nolo) also generate these documents.
Once signed, give copies to:
- Your proxy and any alternate proxy
- Your primary care physician
- Any specialists involved in your regular care
- Your local hospital (many maintain patient preference files)
- Your estate attorney
Keep the original in your FinalKeepSake vault or another secure, accessible location — not in a safe deposit box that can't be accessed in an emergency.
