How to Choose a Healthcare Proxy For Your Needs
December 09, 2025
Making healthcare decisions is straightforward when you're able to communicate your wishes. But what happens if you become unable to speak for yourself due to illness or injury? A healthcare proxy (also called a medical power of attorney) ensures someone you trust can make medical decisions based on your values and preferences. As an expert in this field, I'll guide you through the process of understanding, selecting, and legally appointing a healthcare proxy across Australia, the UK, and the US.
Understanding Healthcare Proxies
A healthcare proxy is a person legally authorized to make medical decisions on your behalf when you're unable to do so. This role goes by different names in various regions:
Australia:
- Medical Treatment Decision Maker
- Substitute Decision-Maker
- Enduring Guardian (for healthcare decisions)
United Kingdom:
- Health and Welfare Attorney
- Personal Welfare Attorney
- Healthcare Proxy
United States:
- Healthcare Agent
- Medical Power of Attorney
- Healthcare Surrogate
- Healthcare Representative
"The healthcare proxy role is one of the most important designations in advance care planning," explains advance care planning. "This person becomes your voice when you cannot speak for yourself."

Why Everyone Should Assign a Healthcare Proxy
Healthcare proxies aren't just for the elderly or those with chronic conditions. Consider these scenarios:
- A 25-year-old in a serious car accident needing emergency surgery
- A 35-year-old experiencing complications during childbirth
- A 45-year-old suffering an unexpected stroke
- A 60-year-old developing sudden cognitive impairment
- Anyone undergoing general anesthesia for a procedure
Without a designated proxy, medical decisions might be made by:
- Healthcare providers who don't know your values
- Family members who may disagree about your care
- Courts appointing someone unfamiliar with your wishes
- Default decision-makers under state/regional laws
"Every adult should have a healthcare proxy—medical emergencies don't discriminate by age or health status," advises online will writing.
Legal Authority and Limitations
The specific powers granted to healthcare proxies vary by jurisdiction:
Australia
- Authority begins only when you lose decision-making capacity
- Proxy must consider your known preferences and values
- Different forms required in different states/territories
- Some treatments may require tribunal approval despite proxy appointment
- Authority typically continues until capacity is regained or death
United Kingdom
- Authority granted through Lasting Power of Attorney for Health and Welfare
- Only applies when you lack mental capacity
- Can include authority for life-sustaining treatment decisions (if specified)
- Must be registered with the Office of the Public Guardian to be valid
- Different systems exist in England/Wales, Scotland, and Northern Ireland
United States
- Authority and requirements vary by state
- Generally begins when physicians certify lack of decision-making capacity
- Some states require specific language for life-sustaining treatment authority
- Authority typically ends if you regain capacity
- HIPAA authorization often included to access medical records
"Understanding the scope and limitations of proxy authority in your jurisdiction is essential for effective planning," notes experts in healthcare decision maker roles.
Who Should Have a Healthcare Proxy?
The simple answer is: every adult. However, it's particularly crucial for:
Young Adults (18-30)
- Those living away from family
- College students
- Military personnel
- Anyone with chronic health conditions
- Individuals with strong treatment preferences
- Those in high-risk professions or activities
Middle-Aged Adults (30-60)

"Even with an advance care directive in place, a healthcare proxy is essential for interpreting your wishes in unanticipated situations," explains family legacy planning.
Qualities of an Effective Healthcare Proxy
When selecting someone to assign health proxy responsibilities, look for these characteristics:
Essential Qualities

- People who avoid difficult conversations or decisions

"Choosing the wrong proxy can be worse than not designating one at all," cautions experts in healthcare proxy assignment.
