If you’ve heard about estate planning, you’ve probably heard the terms “power of attorney” and “advanced healthcare directive” thrown around. Sometimes they’re used like they’re the same thing, which is part of the problem. They’re not the same thing. 

Power of Attorney = you appoint someone to manage your money and legal matters. This can include paying bills, managing accounts, handling real estate, files taxes. A financial role.

Advanced Healthcare Directive = you appoint someone to manage your medical care. You’ll name someone who talks to doctors for you, and spells out what treatments you do or don’t want. A medical role.

One covers your wallet. The other covers your body. You need both.

First, a Little Context

The basic idea is this: what happens if you’re alive but unable to make your own decisions? Maybe you’re unconscious after an accident. Maybe you’re in the middle of surgery. Maybe a stroke or dementia has affected your ability to communicate your wishes. This is called incapacitation, and both a power of attorney and an advanced healthcare directive fall under this category.

In those moments, someone needs to be able to act on your behalf—and without the right estate planning documents in place, that process can become complicated, expensive, and emotionally exhausting for your family. These two documents are how you prevent that.

What Is a Power of Attorney?

A power of attorney is a legal document that gives another person the authority to act on your behalf. The person you choose is called your “agent” (sometimes called an “attorney-in-fact,” which is just a legal term and doesn’t mean they have to be an actual lawyer).

In the context of estate planning, the most common type is a durable power of attorney for finances. This gives your agent the ability to handle your financial and legal matters: paying bills, managing bank accounts, handling real estate transactions, filing taxes, running a business, and so on. The word “durable” is important—it means the document stays in effect even if you become incapacitated. A regular (non-durable) power of attorney would automatically end the moment you lose capacity, which would defeat the whole purpose.

In Kansas, a durable power of attorney is governed by the Kansas Uniform Power of Attorney Act. Your agent has a legal duty to act in your best interest, keep records of their actions, and follow your instructions. Choosing someone trustworthy for this role is very important because they’ll have significant access to your finances.

What Is an Advanced Healthcare Directive?

An advanced healthcare directive—sometimes called a living will, healthcare directive, or advance directive—is a document that addresses medical decisions, not financial ones. It has two main purposes: it tells healthcare providers what kinds of medical treatment you do or don’t want if you can’t speak for yourself, and it names someone to make medical decisions on your behalf.

In Kansas, the advanced healthcare directive typically combines two things that used to be separate documents:

1. The healthcare proxy (or healthcare power of attorney): This names a specific person (your healthcare agent) who is authorized to speak with doctors, review your medical records, and make medical decisions on your behalf when you can’t. This is the person who talks to the hospital when you’re in the ICU. Their job is to make sure your wishes are followed.

2. The living will portion: This is where you define your actual wishes. Do you want life-sustaining treatment continued if you have no reasonable chance of recovery? What are your wishes about resuscitation, mechanical ventilation, and artificial nutrition? What matters to you in terms of quality of life? These are hard questions, but writing them down means your family doesn’t have to guess and carry the stress of making those decisions on their own. You’ll be doing your family a great favor, even though the chance of the circumstance is hard to confront. 

Kansas law allows you to be as specific or as general as you like in your advance directive. Some people write detailed instructions. Others keep it broader and trust their healthcare agent to use good judgment based on their values. There’s no single right approach.

Can You Appoint The Same Person to Do Both?

Yes, absolutely. Many people name their spouse, an adult child, or a close sibling for both roles. If you have one person you trust completely (someone who is organized, level-headed, and knows you well), there’s nothing wrong with putting them in charge of both.

That said, some people split the roles intentionally. Maybe the family member who’s best at handling finances lives far away and wouldn’t be the right person to be physically present at a hospital, making medical decisions. Or maybe you have one child who’s a natural caretaker and another who’s really smart with finances. Splitting the roles can work well, just make sure both people understand their responsibilities and know where the documents are.

Why You Need Both—Not Just One

This is where a lot of people get tripped up. They create one document and think they’re covered, or they assume their spouse can automatically handle everything if something happens to them. Neither assumption is safe.

In Kansas, your spouse does not automatically have legal authority to manage your finances if you become incapacitated; instead, they would need to go through a court process called guardianship or conservatorship to get that authority, which takes time and money and adds stress on top of an already hard situation. A durable financial power of attorney prevents that.

Similarly, even a spouse doesn’t automatically have unlimited authority to make medical decisions on your behalf without a healthcare directive in place. Having your wishes written down (and naming a specific person to advocate for them) means there’s no vagueness and no family conflict about who’s in charge.

Having both documents means all the bases are covered: your finances are protected, your medical wishes are known, and the people you trust most are allowed to act without having to go to court.

What Happens If You Don’t Have These Documents?

This is the part nobody likes to think about, but it’s worth being honest about.

If you become incapacitated without a durable financial POA, someone will likely need to go to court to be appointed your conservator in order to manage your finances. This process can be slow, expensive, and public. It can also result in someone being appointed who isn’t who you would have chosen.

If you become incapacitated without a healthcare directive, medical decisions will fall to your family, but they may not agree on what you would have wanted. Hospitals and doctors, doing their best to act in your interest, may default to aggressive intervention even if that’s not what you would have chosen. Without a named healthcare agent, there can be confusion about who has the authority to speak on your behalf.

These situations create real pain for families, not because anyone did anything wrong, but because the right documents weren’t in place.

If you’ve been putting it off, now’s a good time to take that first step.
