Healthcare Proxy: How to Choose One for Your Aging Parent

When your parent is lying unconscious in the ICU, a doctor will turn to someone in the family and say: "We need to make a decision about treatment. Who has the authority to decide?"

If your parent has named a healthcare proxy, the answer is clear. If they haven't, the family is suddenly navigating a medical crisis and a legal ambiguity at the same time — often with siblings who disagree about what to do.

A healthcare proxy is the single most important end-of-life document your parent can create. Here's how to choose the right person and set it up properly.

What a healthcare proxy does

A healthcare proxy (also called a medical power of attorney or health care agent) is a person your parent designates to make medical decisions on their behalf when they can't make decisions for themselves.

The proxy steps in when two conditions are met:

1. Your parent is unable to communicate their own wishes (due to unconsciousness, severe cognitive impairment, sedation, or other incapacity)
2. A medical decision needs to be made

The proxy's role is not to impose their own beliefs. It's to represent the patient's values and wishes as faithfully as possible — using the living will as a guide, their personal knowledge of the patient to fill gaps, and their best judgment for situations no one anticipated.

How to choose the right person

Not every family member is suited for this role. The right healthcare proxy is someone who:

Can stay calm under pressure

Medical crises are chaotic. Doctors deliver information quickly, decisions have deadlines, and emotions are running high. The proxy needs to be someone who can process information, ask questions, and make decisions without freezing, panicking, or deferring out of fear.

Knows your parent's values

Not just their medical preferences — their core values. Does your parent value independence over longevity? Is faith a factor in their medical decisions? How do they define "quality of life"? The proxy needs to understand these values deeply enough to extrapolate decisions for scenarios the living will didn't cover.

Will follow your parent's wishes, even when they disagree personally

This is the hardest criterion. If your parent doesn't want CPR but the proxy believes everything should be done to save a life, the proxy may override the patient's wishes under emotional pressure. The proxy must be someone who can separate their own feelings from their responsibility.

Is geographically accessible

In a medical emergency, the proxy may need to be reachable within hours, not days. A sibling who lives across the country may be the best choice emotionally, but if they can't be physically present or available by phone during critical decision windows, their role becomes harder to fulfill.

Is willing to serve

Being named as a healthcare proxy is a significant responsibility. Ask the person before designating them. Explain what it involves. Give them the opportunity to say no — better to know now than to discover reluctance during a crisis.

Who should NOT be the proxy

The person most likely to be too emotionally overwhelmed. If one of your parent's children cannot handle medical stress — they faint at blood, they freeze during emergencies, or they've expressed that they "can't deal with this" — that person should not be the proxy, regardless of birth order.

The person who will fight with siblings. If naming one sibling as proxy will trigger an immediate family war, consider whether there's an alternative — a different family member, a trusted friend, or even a professional patient advocate — who can serve without igniting conflict.

The person your parent doesn't trust with this decision. It sounds obvious, but family dynamics sometimes lead to the "wrong" person being named because they're the oldest, the closest, or the loudest. The proxy should be the person your parent trusts most, full stop.

Setting up the healthcare proxy

The legal process

1. Obtain the form. Each state has its own healthcare proxy form, available free from the state health department website. The Five Wishes document also includes a proxy designation and is valid in most states.

2. Your parent completes and signs the form. They must be mentally competent at the time of signing. Most states require witnesses — typically two adults who are not the named proxy and who are not likely to inherit from the patient.

3. Name a backup. The form should designate an alternate proxy in case the primary person is unavailable, unwilling, or unable to serve when needed.

4. Distribute copies. Give copies to: the named proxy, the alternate proxy, your parent's primary care doctor, the local hospital, and close family members.

5. Tell the proxy what your parent wants. The form alone isn't enough. The proxy needs to understand your parent's medical preferences, values, and the reasoning behind their choices. Have a detailed conversation — ideally with your parent present.

Pair it with a living will

A healthcare proxy without a living will puts the proxy in a difficult position: they have the authority to decide but no documented guidance about what the patient wants. A living will without a proxy is equally incomplete: the document states preferences but there's no designated person to interpret and enforce them.

Together, these two documents form a complete advance directive. The living will provides the roadmap. The proxy navigates when the road isn't on the map.

Common questions

Does the proxy make financial decisions? No. A healthcare proxy covers medical decisions only. Financial decisions require a separate financial power of attorney. The same person can hold both, but they're separate legal documents.

Can the proxy override the living will? Generally, no. The proxy's job is to follow the patient's documented wishes. If the living will clearly addresses a situation, the proxy should honor it. The proxy's judgment comes into play for scenarios the living will didn't address.

Can my parent change their proxy? Yes, at any time, as long as they're mentally competent. Simply complete a new form and notify everyone who had the old one.

Does the proxy designation expire? In most states, no — it remains in effect until revoked. But it should be reviewed regularly to ensure the named person is still appropriate and willing.

Does it work across state lines? This varies. Some states honor out-of-state proxy designations, others don't. If your parent divides time between states, consider having forms completed for each state.

Don't put this off

Most families don't think about healthcare proxies until a parent is already in the hospital. By then, it may be too late — the parent must be mentally competent to designate a proxy. If they're already incapacitated, the family must petition the court for guardianship, which is expensive, slow, and disempowering.

Set up the healthcare proxy while your parent is healthy and clear-headed. It takes 20 minutes and costs nothing. The protection it provides is immeasurable.
