What Is Power of Attorney and Do I Need It?

If someone you love is getting older, has been diagnosed with a serious illness, or had a health scare that made you both realize you probably should have had some conversations a while ago — you've likely heard the phrase "Power of Attorney" come up. Maybe from a doctor, a financial advisor, or a well-meaning friend who's been through it.

Here's what it actually means, whether you probably need it, and what happens if you don't have it when you do.

The Basics

Power of Attorney (POA) is a legal document in which one person — the principal — gives another person — the agent, sometimes called the attorney-in-fact — the authority to make decisions on their behalf. Those decisions can cover finances, healthcare, or both, depending on how the document is drafted.

The critical word in that definition is gives. POA is a voluntary arrangement. The person granting the authority has to be mentally competent to do so — they have to understand what they're agreeing to. This is why it matters so much to set it up before a crisis rather than during one.

The Types You'll Encounter

Financial POA gives the agent authority over money matters: bank accounts, investments, bill payment, tax filings, real estate transactions. This is the type you'll need when dealing with most financial institutions.

Healthcare POA (also called a medical POA or healthcare proxy) gives the agent authority to make medical decisions — choosing doctors, consenting to procedures, directing care when the principal can't speak for themselves.

Durable POA is not a separate type, but a critical feature. A durable POA remains valid even after the principal becomes incapacitated. Without durability language, a POA can lapse at exactly the moment you need it most. Most modern POA forms are durable by default — but always confirm this explicitly.

Many families set up both financial and healthcare POA at the same time. In most states, they're separate documents.

Do You Need It?

Probably yes, if any of the following are true:

• You're managing finances or care for someone who has difficulty doing so themselves

• Your loved one has a diagnosis that's likely to affect their cognition over time

• You're already handling bills, insurance calls, or doctor appointments on their behalf

• You're managing any of this from a distance

Here's the practical reality: without POA, banks won't talk to you about someone else's account. Doctors won't share information with you. Insurance companies won't let you file claims or make changes. Government agencies — Social Security, Medicare, the IRS — have their own walls. You can be the most devoted, involved family member in the world, and institutions will still turn you away without the right documentation.

That documentation is POA.

What Happens Without It

If something happens to your loved one and no POA exists, your options narrow significantly. You may be able to get limited access to some accounts with other documentation — or you may need to pursue guardianship or conservatorship through the courts, a process that's slower, more expensive, and much more invasive than simply having a POA in place.

The families who have the hardest time are almost always the ones who knew they should have done this and kept putting it off. Not because they were negligent — because it's an uncomfortable conversation, because things felt stable enough, because there was always something more urgent on the list.

If that sounds familiar: this is the nudge. The conversation you have today is much easier than the one you'll have from a hospital waiting room.

How to Get Started

The most important step is making sure the document is legally valid in your state, covers the authority you actually need, and is properly executed — signed, witnessed, and notarized according to your state's requirements. Working with an elder law attorney is the safest approach, and it's worth every dollar.

Once you have the document, the work isn't done — you'll need to register it with banks, healthcare providers, insurance companies, and government agencies, each of which has its own process. That's what we're here to help you navigate.
