Most people think of estate planning as something that kicks in after you die. You write a will, name your beneficiaries, maybe set up a trust, and you're done. But here's the uncomfortable truth: the most urgent planning you need to do isn't about what happens after death. It's about what happens while you're still alive but can't speak for yourself.
A car accident. A stroke. An unexpected surgery that goes sideways. In any of these scenarios, your will is useless. It sits in a drawer doing nothing while your family scrambles to figure out who's allowed to make decisions about your medical care, your finances, and your wishes — often with no legal authority to do any of it.
According to a systematic review published in Health Affairs, only about one in three American adults has completed any type of advance directive.[1] That means roughly two out of three people have no documented plan for what should happen if they become incapacitated. And a 2023 AARP survey found that even after COVID forced millions to confront their own mortality, a majority of older adults still hadn't completed a medical durable power of attorney or advance care directive.[2]
These aren't obscure legal technicalities. They're the documents that determine whether your family can act quickly during a crisis — or whether they end up in court.
The Three Documents That Protect You While You're Alive
Think of your incapacity plan as a three-legged stool. Remove any one leg and the whole thing collapses. Here's what each document does, why it matters, and what happens without it.
1. Healthcare Proxy (Medical Power of Attorney)
A healthcare proxy — sometimes called a medical power of attorney or durable power of attorney for healthcare — is a legal document that names a specific person to make medical decisions on your behalf when you can't make them yourself.[3]
This isn't about end-of-life care specifically (that's the living will's job). Your healthcare proxy covers the full range of medical decisions: whether to proceed with a surgery, which facility to transfer you to, whether to try an experimental treatment, which specialists to consult. It also typically grants your agent authority to access your medical records and communicate directly with your healthcare providers.
Without one: Hospitals default to a state-defined hierarchy — usually spouse, then adult children, then parents, then siblings. If you're unmarried, estranged from family, or if your family members disagree, the hospital may require a court-appointed guardian before anyone can authorize treatment. That process takes weeks or months while you lie in a hospital bed.
2. Durable Power of Attorney (Financial)
A durable power of attorney gives someone you trust the legal authority to handle your financial affairs if you become incapacitated.[4] This includes paying your bills, managing your bank accounts, filing taxes, handling insurance claims, running your business, and — in some states — making adjustments to your estate plan.
The word "durable" is critical here. A standard power of attorney expires the moment you become incapacitated — which is exactly when you need it most. A durable power of attorney explicitly survives your incapacity. Some people opt for a "springing" version that only activates upon a determination of incapacity, but many estate planners now recommend the immediately effective version because proving incapacity to trigger a springing POA can create delays during a crisis.
Without one: Your mortgage still needs to be paid. Your business still needs to be managed. Your investments may need to be rebalanced. But nobody has legal authority to touch any of it. Your family's only option is to petition a court for conservatorship or guardianship — an expensive, public, and time-consuming process that can cost thousands in legal fees and drag on for months.
3. Living Will (Advance Directive)
A living will puts your specific treatment preferences in writing for situations where you can't communicate them yourself.[5] It typically addresses questions like: Do you want to be kept on life support if you're in a persistent vegetative state? Do you want artificial nutrition and hydration? Under what circumstances do you want resuscitation attempts to stop?
This is the document that speaks for you about what you want. Your healthcare proxy decides how to execute your care day to day, but your living will draws the lines you don't want anyone to cross — or that you want them to fight to maintain.
Without one: Your family is left guessing. And when family members guess differently, the consequences can be catastrophic.
What Happens When These Documents Don't Exist
You don't have to look far for cautionary examples. Families end up in court over incapacity decisions every day. But one case became a national inflection point.
In 1990, Terri Schiavo collapsed in her Florida home and suffered severe brain damage. She was eventually diagnosed as being in a persistent vegetative state. She had no healthcare proxy, no living will, and no advance directive of any kind.
What followed was a seven-year legal battle between her husband, who believed she would not have wanted to be kept alive artificially, and her parents, who wanted to continue all life-sustaining treatment. The case eventually involved twenty different judges, the Florida legislature, the U.S. Congress, and the President of the United States.[6]
A case study published in Mayo Clinic Proceedings described it as the most volatile and litigated end-of-life case in American legal history — and the entire dispute centered on a single question that a living will could have answered in one paragraph: what did Terri want?
“The Schiavo case wasn't about medicine or politics. It was about a family torn apart because one document didn't exist. A living will — even a simple one — would have given everyone a clear answer and avoided seven years of litigation.”
The Schiavo case is extreme. But smaller versions of this story play out constantly in hospitals and courthouses across the country. Siblings who disagree about a parent's care. Unmarried partners shut out of medical decisions because they have no legal standing. Adult children unable to pay a parent's rent because no power of attorney exists. These situations are preventable. They just require paperwork that most people never get around to completing.
The Surprise Most Parents Miss: Your 18-Year-Old Needs These Too
Here's something that catches almost every parent off guard. The moment your child turns 18, you lose all legal authority over their medical and financial decisions. Completely. Overnight.[7]
It doesn't matter that you're still paying for their health insurance. It doesn't matter that they're living in your house or that you're financing their college education. Under the law, they are a legal adult, and HIPAA regulations prohibit healthcare providers from sharing their medical information with you without their explicit written consent.
Picture this: your 19-year-old is in a car accident 500 miles away at college. They're unconscious in the ICU. You rush to the hospital. And when you get there, the doctors tell you they cannot discuss your child's condition, you cannot access their medical records, and you cannot authorize treatment — because your child is a legal adult and you have no documentation granting you authority.
This isn't a hypothetical designed to scare you. It's a routine legal reality that every parent of a college-age kid needs to plan for.
Before your child leaves for college — ideally on or shortly after their 18th birthday — they should sign three documents:
- A healthcare proxy naming you (or another trusted adult) as their medical decision-maker
- A HIPAA authorization giving you access to their medical records
- A durable power of attorney allowing you to manage financial matters on their behalf in an emergency
These documents are straightforward, inexpensive to prepare, and can be completed in a single sitting with an attorney. AARP even offers free advance directive forms by state that can serve as a starting point.[5]
How These Documents Connect to Your Broader Plan
Incapacity planning doesn't exist in a vacuum. These three documents are part of a larger system that includes your will, your beneficiary designations, and your overall estate plan.
Your beneficiary designations on retirement accounts, life insurance policies, and bank accounts determine where your assets go when you die — and they override whatever your will says. If your beneficiary designations are outdated, your durable power of attorney agent may not be able to fix them while you're incapacitated.
Your will handles asset distribution after death, but your durable power of attorney handles asset management during incapacity. If these two documents name different people — or if the people they name have conflicting views about how your affairs should be managed — you're setting the stage for family conflict.
A platform like Heirloom can help you see all of these pieces in one place: your will, your advance directives, your beneficiary designations, and the people responsible for each. When everything is visible and organized, gaps become obvious and fixable.
Common Questions (and Honest Answers)
Do I need a lawyer? Technically, in most states, you can complete these documents using free forms. Practically, if your situation involves blended families, significant assets, business ownership, or complicated family dynamics, an attorney's guidance is worth the cost. The American Bar Association maintains resources to help you understand what each document requires in your state.[4]
Can one person serve as both my healthcare proxy and financial POA? Yes, and many people choose this route for simplicity. But you can also split the roles if different people are better suited to each. Just make sure both agents know about each other.
Do these documents expire? Generally, no. A durable power of attorney remains valid until you revoke it or you die. However, some healthcare directives may need to be re-executed if you move to a different state, since requirements vary. It's good practice to review all three documents every three to five years or after any major life change — marriage, divorce, a new diagnosis, or the death of a named agent.
What if my agent disagrees with my living will? Your living will takes precedence. The agent's job is to carry out your stated wishes, not to substitute their own judgment. If an agent refuses to honor a living will, healthcare providers can — and in many states, must — follow the directive directly.
What You Can Do This Week
You don't need to hire a lawyer, research every state statute, or block off a full weekend for this. Start with one step. Then take the next one.
Find out what you already have. Check with your doctor's office, your attorney (if you have one), and your own files. You may have signed an advance directive during a hospital admission and forgotten about it. Know your starting point.
Download your state's free forms. AARP provides free advance directive forms for every state, including instructions. You can complete a healthcare proxy and living will in under an hour.[5]
Have the "who" conversation. Before you fill in a name on any form, talk to the person you're considering. Being someone's healthcare proxy or financial agent is a serious responsibility. Make sure they understand what it involves, that they're willing to take it on, and that they know your values well enough to act on them.
If your child is 18 or older, put these documents on the calendar this month. Don't wait for a crisis. A healthcare proxy, HIPAA release, and durable power of attorney for a healthy young adult are simple, fast, and inexpensive — but they must be signed before something goes wrong.
Tell your people where these documents live. A healthcare proxy locked in a safe-deposit box at 2 a.m. on a Saturday is functionally useless. Give copies to your named agents, your primary care doctor, and at least one other trusted person. Store digital copies somewhere accessible.
The documents that protect you while you're alive are the ones most people skip. They're not dramatic. They don't involve dividing up assets or naming heirs. But when something goes wrong — and for most families, eventually something does — they're the difference between a crisis that gets handled and a crisis that spirals into something much worse.
