What Is a Health Care Proxy and How Does It Work?

February 5, 2025

A health care proxy is a legal document appointing someone to make medical decisions for you if you’re incapacitated.

Having a health care proxy ensures that your medical wishes are followed—even if you’re unable to communicate them yourself. This legal document gives someone you trust the power to make medical decisions on your behalf. Without it, your loved ones may face confusion, stress, and even legal obstacles during critical moments.

What is a health care proxy?

A health care proxy is a legal document that allows you to designate someone—often called an agent or proxy—to make medical decisions for you if you become unable to do so. This could happen due to illness, injury, or unconsciousness.

An Important Decision

Choosing a proxy is an important decision. The person you select should understand your values and be willing to advocate for the care you want. Most people choose a close family member or friend, but you can name anyone you trust to carry out your wishes.

Once you establish a health care proxy, it becomes active only if you’re unable to make medical decisions yourself. As long as you can communicate your preferences, doctors will follow your instructions directly. However, if you are incapacitated, your proxy steps in and works with medical professionals to ensure you receive the treatment you would have chosen.

How It Works in Real Life

Consider this scenario: Emma, a 68-year-old woman, suffers a severe stroke that leaves her unable to speak. Before the stroke, she named her daughter, Sarah, as her health care proxy. When doctors recommend treatments, Sarah can make informed decisions based on what her mother previously expressed. Sarah can act without delays or legal complications because her mother named her as a legally recognized health care proxy. 

In another case, David, a 45-year-old father, is in a car accident that puts him in a coma. His wife, Maria, assumes she has the right to make medical decisions for him, but the hospital requires legal documentation. Because David never set up a health care proxy, his family has to go through the courts to determine who can act on his behalf. This causes unnecessary delays and stress during an already emotional time.

What Happens Without a Health Care Proxy?

If you don’t have one, your loved ones may not have the authority to make medical decisions for you. In many states, doctors will turn to the closest legal relative, but if family members disagree, the situation can become complicated. In some cases, a court may need to appoint a legal guardian, delaying critical medical decisions.

Not having a designated proxy can also lead to confusion about your wishes. Without clear guidance, family members might struggle to make the right choice, leading to guilt and uncertainty about whether they honored your preferences.

How to Set One Up

Setting up a health care proxy is a straightforward process. Start by choosing someone who understands your values and will respect your decisions. Discuss your medical preferences with them so they feel confident advocating for your wishes.

Next, complete a health care proxy form, which varies by state. Most states require your signature and either witness signatures or notarization. Once the document is final, share copies with your proxy, your doctors, and close family members to ensure everyone is aware of your choice.

A Health Care Proxy Means Control

Advance health care directives like a health care proxy gives you control over your medical care—even when you can’t speak for yourself. By naming someone you trust, you can prevent confusion, delays, and legal hurdles in times of crisis. Preparing now ensures that your health care decisions align with your wishes, making things easier on your loved ones.
