Living Wills vs. Medical Power of Attorney: Which One Should You Choose?

Bochnewich Law Offices July 28, 2025

Planning ahead for your medical care may not be the most comfortable topic, but it’s one of the most important things you can do to protect your wishes. When you're no longer able to speak for yourself, having clear legal documents in place makes all the difference. Two of the most commonly used tools in this situation are the living will and the medical power of attorney.

While both are designed to guide your medical care when you're incapacitated, they work in different ways and serve different purposes. Here at Bochnewich Law Offices in Palm Desert, California, our probate attorneys help individuals and families create clear estate plans, including living wills and medical powers of attorney, to protect their wishes.

What Is a Living Will?

A living will is a written legal document that outlines your preferences for medical treatment if you become unable to make those decisions yourself. It's not about passing assets through probate or managing finances—it's strictly about your healthcare choices.

People usually use a living will to state their wishes regarding life-sustaining treatment, such as:

  • Resuscitation if your heart stops

  • Use of ventilators if you're unable to breathe on your own

  • Tube feeding and hydration

  • Palliative care or pain management

  • Organ and tissue donation preferences

These instructions help guide doctors and hospitals when you can't give them direct input. They're particularly useful in situations involving terminal illness or irreversible coma.

What Is a Medical Power of Attorney?

A medical power of attorney (also known as a healthcare proxy) allows you to appoint someone to make healthcare decisions on your behalf if you're incapacitated. Unlike a living will, which gives specific instructions, a medical power of attorney gives someone the authority to make real-time decisions based on your current medical situation.

Here are some of the things your appointed agent can do:

  • Talk with doctors and review medical records

  • Choose between treatment options

  • Approve or decline surgical procedures

  • Decide whether to move you to a different care facility

  • Follow your known wishes or make a judgment call if no prior direction was given

This document becomes active only when you can't speak for yourself, and it ends once you're able to make your own decisions again.

Key Differences Between the Two

Although both documents are used in healthcare planning, there are several important distinctions between a living will and a medical power of attorney.

Differences to consider:

  • Scope: A living will outlines specific treatments you do or don't want; a medical power of attorney gives decision-making authority to someone else.

  • Flexibility: A medical power of attorney allows your agent to respond to unexpected medical developments. A living will can't adapt to new situations unless explicitly stated.

  • Timing: A living will is used primarily in end-of-life care or when recovery isn't likely. A medical power of attorney covers a broader range of scenarios.

  • Personal interaction: A living will is static and silent. A healthcare proxy can speak with doctors and advocate for you.

Understanding these differences helps highlight how these documents can either work alone or complement each other. One doesn't necessarily replace the other.

Situations Where You Might Want a Living Will

If you have strong preferences about specific treatments and want them honored without question, a living will can give you peace of mind. It's particularly helpful in circumstances where there may not be time for a proxy to make an informed decision or where family members might disagree.

A living will might be right for you if:

  • You've been diagnosed with a terminal illness and have already decided what treatments you do or don't want

  • You're concerned about being kept alive artificially

  • You want to spare your family the stress of making life-or-death decisions

  • You're worried about potential disagreements among loved ones

That said, a living will doesn't cover every possible medical situation. It's most effective when combined with other forms of planning.

Situations Where You Might Prefer a Medical Power of Attorney

Sometimes, it's hard to predict exactly what kind of care you'll want or need. That's when appointing someone you trust as your healthcare agent can be incredibly valuable. They can consider your values, your past conversations, and the medical facts at hand.

A medical power of attorney may be a better fit if:

  • You trust someone deeply to make thoughtful decisions for you

  • You want someone to communicate with doctors in real-time

  • You believe flexibility is important in unpredictable medical situations

  • Your treatment preferences depend on context and might change

This is especially true for people who don't have specific treatment instructions but want their wishes represented.

Why Many People Choose Both

You don’t necessarily have to pick between a living will and a medical power of attorney. Many attorneys who work with probate and estate planning in California recommend creating both documents. This approach gives you the benefit of clearly stated wishes along with a trusted voice to advocate for you.

Benefits of having both documents:

  • Combining the clarity of written instructions with the adaptability of a proxy

  • Reduces the risk of disputes among family members

  • Strengthens your overall healthcare plan

  • Supports your probate plan by minimizing stress during a crisis

By taking both steps, you're providing more complete guidance and reducing ambiguity during already difficult times.

How These Documents Fit Into the Probate Process

Even though living wills and medical powers of attorney don't directly affect the probate process, they still play a big role in your broader estate plan. Probate in California can be time-consuming and emotionally draining for families, especially if there are disagreements or gaps in legal planning.

Here's how healthcare documents help reduce stress during probate:

  • They provide clarity on your wishes, which can prevent disputes

  • They make it easier for loved ones to follow your plan without going to court

  • They support a smoother transition from medical to legal decision-making after death

Taking the time to prepare these documents can reduce the emotional toll on your family and complement the rest of your probate documents, like wills and trusts.

Choosing the Right Person for Medical Power of Attorney

If you decide to assign a healthcare agent, choosing the right person is crucial. This person may need to make life-changing decisions under pressure, so they should be someone who understands your values and can handle emotional conversations.

Qualities to look for in a healthcare agent:

  • Emotionally steady in difficult situations

  • Capable of making decisions under pressure

  • Familiar with your healthcare values

  • Willing to speak up to doctors and family members

  • Lives nearby or is easy to reach in an emergency

It's also a good idea to discuss your wishes with this person in advance. You can use your living will as a guide to discuss what matters to you and why. For more information, contact Attorney Peter M. Bochnewich at our office today. 

Keeping Your Documents Up to Date

Life changes, and so should your legal documents. Whether it's a change in your health, your relationships, or your priorities, it's important to review your living will and medical power of attorney periodically.

When you should consider an update:

  • After a major health diagnosis

  • If your chosen agent is no longer available

  • Following a marriage, divorce, or other major life event

  • When you change your mind about specific treatments

Keeping your documents current helps make sure they still reflect your wishes and align with your broader probate plan.

Talking With Family About Your Choices

Talking about serious medical issues can be uncomfortable, but it's often necessary. A calm conversation now can save your family a lot of stress later.

Tips for a productive discussion:

  • Choose a quiet, private setting

  • Explain why you've made your choices

  • Listen to your family’s questions and concerns

  • Share a copy of your documents

  • Reassure them that your goal is to make things easier, not harder

Having this discussion can bring your family together and help avoid tension during medical emergencies or probate proceedings.
