Turning eighteen comes with a lot of exciting milestones.
You can vote. You can sign contracts. You can make your own medical decisions. You can open accounts, start a career, move away for college, or begin building a life that is entirely your own.
But there is one adult decision that most eighteen-year-olds never think about:
Who gets to speak for me if I can’t speak for myself?
That question can feel far away when your biggest concern is passing your next exam, figuring out your first apartment, or deciding what to do after graduation.
But legally, turning 18 changes something important.
Your parents no longer automatically have the authority they once had to make decisions for you.
And if you haven’t decided who should step in when you can’t?
The law has.
“But I’m Their Parent.”
We hear this all the time.
A parent finds out their 18-year-old child has been in an accident, is unconscious, and needs medical care.
They expect to walk into the hospital, speak with the doctors, access information, and make decisions.
After all, they’re Mom or Dad.
But legally, that relationship changes when a child becomes an adult.
Parents don’t automatically retain the same authority they had when their child was a minor.
Medical providers may be restricted in what information they can share. Financial institutions may refuse to provide access. And if an important decision needs to be made, the family may discover that being someone’s parent isn’t the same thing as having legal authority to act on their behalf.
That’s when a simple question becomes a very complicated problem:
“Who is legally allowed to make this decision?”
The Documents That Answer the Question
This is why young adults need basic legal planning of their own.
For most young adults, that doesn’t mean creating an elaborate estate plan with dozens of documents.
It means putting a few critical protections in place.
1. Advance Health Care Directive
An Advance Health Care Directive allows a young adult to designate someone they trust to make medical decisions for them if they are unable to do so.
That person could be a parent.
It could be a sibling.
It could be a spouse or another trusted individual.
The important part is that the young adult gets to choose.
2. HIPAA Authorization
A HIPAA authorization can allow designated people to receive protected health information.
That can be incredibly important when a family is trying to understand what is happening medically.
Without appropriate authorization, loved ones may find themselves standing outside the circle of information, even when they are desperately trying to help.
3. Durable Power of Attorney
Health care isn’t the only area where things can go wrong.
What happens if your 19-year-old is hospitalized and someone needs to handle financial or legal matters on their behalf?
A Durable Power of Attorney allows a young adult to designate someone they trust to act for them in certain financial and legal matters if they become unable to do so.
Again, the key is choice.
Instead of leaving the question to the law, they can decide who they want in their corner.
The College Student Scenario
Imagine your child leaves for college.
They’re 18.
They’re healthy.
They’re independent.
They’re busy.
Estate planning is probably somewhere near the bottom of their priority list.
Then, completely unexpectedly, there’s an accident.
Your child is unable to communicate.
You are hundreds of miles away.
You get on a plane and head to the hospital.
And then someone asks:
“Do you have legal authority to make decisions for your child?”
That is not a question any parent wants to encounter in the middle of a crisis.
The good news?
It doesn’t take a crisis to solve it.
It takes a conversation beforehand.
This Isn’t About Expecting Something Bad to Happen
Sometimes parents hesitate to bring up estate planning with their young adult because they don’t want to scare them.
We understand.
Nobody wants to sit their 18-year-old down and say, “Let’s talk about what happens if you’re incapacitated.”
But that’s not really what this planning is about.
It’s about recognizing that adulthood comes with both freedom and responsibility.
At 18, your child gets to make their own decisions.
Estate planning simply helps make sure their wishes—and the people they trust—are legally recognized when they can’t make those decisions themselves.
It’s not about expecting the worst.
It’s about being prepared for the unexpected.
Let Them Make the Decision
The biggest mistake isn’t necessarily failing to create a complicated estate plan.
It’s assuming that “someone will be able to figure it out.”
Maybe they will.
But maybe they won’t.
And if your young adult hasn’t made the decision, a judge, a statute, a hospital policy, or another legal process may end up determining what happens next.
That’s a decision worth making before you need it.
Turning 18 is about becoming an adult.
One of the first adult decisions they should make is simple:
Who do I trust to speak for me when I can’t?
Don’t leave that answer to the law.
Make the decision while you can.
