Choosing a healthcare decision maker—also called your healthcare power of attorney—is one of the most important decisions in your advance care plan.
But for many families, it’s also one of the hardest.
Should it be your spouse? Your oldest child? The one who lives closest? The one who “knows you best”?
The truth is, the right choice isn’t always the obvious one.
What Does a Healthcare Decision Maker Actually Do?
Your healthcare agent is responsible for making medical decisions on your behalf if you’re unable to do so.
This can include:
- Communicating with doctors
- Evaluating treatment options
- Making urgent or end-of-life decisions
- Advocating for your wishes, even under pressure
This role isn’t symbolic. It’s active, emotional, and sometimes very difficult.
The Most Common Mistake Families Make
Many people choose their decision maker based on:
- Birth order
- Proximity
- Avoiding hurt feelings
But this decision shouldn’t be about fairness, it should be about capability.
Choosing the wrong person can lead to:
- Delays in care decisions
- Conflict among family members
- Decisions that don’t reflect your wishes
What to Look for in the Right Person
The best healthcare decision maker is someone who:
✔ Can Stay Calm Under Pressure
Medical situations can be fast-moving and emotionally charged. You need someone who can think clearly in stressful moments.
✔ Will Advocate for Your Wishes (Not Theirs)
This person must be able to set aside their own opinions and honor what you want, even if it’s difficult.
✔ Communicates Well
They’ll be speaking with doctors, nurses, and potentially other family members. Clear communication is essential.
✔ Is Willing to Take on the Role
Not everyone is comfortable making medical decisions. This should be a conversation, not a surprise.
Should You Choose More Than One Person?
In Missouri, you can name:
- A primary decision maker
- One or more backup (successor) agents
Naming co-agents (multiple people at the same level) can sometimes create complications if they disagree.
In most cases, it’s best to:
- Choose one primary person
- Name backups in case your first choice is unavailable

What If Your Family Might Disagree?
Family dynamics matter.
If there’s potential for conflict, your choice becomes even more important.
A strong decision maker can:
- Reduce confusion
- Prevent disputes
- Provide clarity during stressful situations

This Decision Works Together With Your Documents
Choosing the right person is only half of the equation.
They also need:
- Clear legal authority (power of attorney)
- Guidance on your wishes (healthcare directive)

This Is Part of a Bigger Plan
A healthcare decision maker plays a critical role, but they shouldn’t be navigating everything alone.
A complete plan includes:
- Legal documents
- Care coordination
- Long-term planning
- Ongoing support for your family

Frequently Asked Questions
Who should I choose as my healthcare power of attorney in Missouri?
You should choose someone you trust to make medical decisions on your behalf if you’re unable to communicate. This person should be able to stay calm under pressure, understand complex situations, and advocate for your wishes with doctors and care providers.
In Missouri, your healthcare power of attorney has legal authority to make decisions based on what you would want—not what others think is best. Choosing someone who respects your values and can handle difficult conversations is critical to ensuring your wishes are followed.
Can I choose more than one healthcare decision maker?
In Missouri, you can name a primary healthcare decision-maker and one or more backup agents. This allows someone else to step in if your first choice is unavailable or unable to serve.
However, naming multiple people to act at the same time can lead to disagreements and delays in decision-making. For this reason, it’s usually best to choose one primary person and designate backups to avoid confusion or conflict.
Does my healthcare decision maker need to live nearby?
No, your healthcare decision-maker does not need to live nearby, although proximity can sometimes make communication easier during emergencies. What matters most is that the person can be reached quickly and is willing to stay involved.
Many decisions can be handled remotely, especially with modern communication tools. In Missouri, the most important factors are trust, judgment, and the ability to communicate clearly—not physical location.
What happens if my family disagrees with my decision maker?
If you have a valid healthcare power of attorney in Missouri, the person you named has legal authority to make medical decisions—even if other family members disagree. This helps prevent confusion and ensures that one person can act without delay.
Disagreements can still happen, especially during emotional situations. That’s why it’s important to communicate your wishes in advance and choose someone who can confidently advocate for you, even if others have different opinions.
Should I talk to the person before naming them?
Yes, you should always talk to the person before naming them as your healthcare power of attorney. This ensures they understand your wishes and are willing to take on the responsibility.
These conversations also help prepare them to make decisions under pressure. Discussing your values, preferences, and priorities ahead of time makes it much easier for your chosen decision-maker to act with confidence if the situation arises.
