Your child turns 18 and, legally, becomes an adult overnight. For most families nothing seems different: same kid, same phone plan, same tuition bill. But in the eyes of doctors, colleges and banks, the parent is now an outsider. If your new adult is in an accident three states away, the hospital may not be able to tell you much, and you may have no say in decisions unless your child has put something in writing first.
This guide walks through the documents families most often look into when a child turns 18, what each one does in plain language, and how to get them done without turning it into a fight. One thing up front: rules and forms vary by state, and this is general information, not legal advice. Use your state's official forms, and talk to an attorney if your situation is complicated.
Why 18 changes things
Before 18, parents are usually the decision-makers and can generally see medical and school records. At 18, privacy rights belong to the young adult. In practice, that means:
- A hospital or doctor's office may decline to share details with you, even in a crisis.
- A college generally will not share grades, records or many other details with you without your student's written consent.
- A bank will not discuss your adult child's account with you unless you are on it or have written authority.
None of this is a problem until something goes wrong. The documents below are how a young adult can choose, in advance, who gets to help.
The five documents to look into
1. HIPAA authorization
HIPAA is the federal privacy law that protects health information. A HIPAA authorization (sometimes called a HIPAA release) is a signed form that lets health care providers share your child's health information with the people they name, such as one or both parents. It does not let anyone make decisions; it lets them be informed. Many hospitals and student health centers have their own version, and a general authorization can be drafted to cover any provider.
2. Healthcare proxy (healthcare power of attorney)
Depending on your state, this may be called a healthcare proxy, a medical power of attorney or a durable power of attorney for health care. It names someone (an "agent") to make medical decisions if your child cannot make or communicate decisions for themselves, for example if they are unconscious after an accident. Most states have a standard form, and many require witnesses, a notary or both.
3. Advance directive or living will
An advance directive records a person's wishes about medical care in situations where they can't speak for themselves. In some states it is combined with the healthcare proxy in a single form. For an 18-year-old this can feel heavy, so it's fine to treat it as optional and come back to it later. The point is to know it exists.
4. Financial power of attorney
A durable financial power of attorney lets a trusted person handle money matters on your child's behalf: paying a bill, talking to a bank, dealing with a lease or a tax issue. This is especially useful if your student is studying abroad or far from home. Requirements vary by state, and some banks have their own forms or rules about accepting them.
5. School records release (FERPA)
FERPA is the federal law that protects student education records. Once a student turns 18 or enrolls in college, those rights move to the student. Many colleges offer a FERPA release or "proxy access" form, often inside the student portal, that lets the student choose what parents can see, such as grades, billing or financial aid. Colleges may be allowed to share some information in limited situations, but you shouldn't count on it. If your student wants you to have access, the school's own form is the way to set it up.
How to get it done in one afternoon
- Talk first, sign second. Your new adult decides which documents they want and who to name. That choice is theirs, and that's the point.
- Find your state's official forms. Good places to look: your state's health department, state bar association or attorney general's website, and the college's registrar or student health office for school and campus forms. If your child lives in one state and goes to school in another, ask an attorney which state's forms make sense.
- Check signing rules. Note whether each form needs witnesses, a notary or both, and who is not allowed to be a witness (often the named agent).
- Sign together. Many banks and shipping stores offer notary services. Bring ID for everyone.
- Store copies where they will be found. Keep the originals somewhere safe, give copies to the people named, and save a scan where your student can pull it up on a phone.
The "if something happens" basics
Documents are only part of it. If your student has an emergency far from home, the people around them need quick answers. A few small things help:
- A medical ID wallet card with emergency contacts, allergies, conditions and medicines. Leave off the Social Security number.
- Medical ID on the phone. Most smartphones let you add emergency contacts and health information that can be viewed from the lock screen.
- A campus plan: the campus safety number, the student health center, the nearest hospital, a local friend or roommate's number, and how your student will reach you.
- Money basics: which bank, the last 4 digits of the account, and how to freeze a lost card. Never write full account numbers or passwords on paper.
How to have the conversation
Teenagers tune out lectures. Questions work better. Try:
- "If you ended up in the hospital, who would you want the doctors to talk to?"
- "Do you want us to be able to see your grades or your bill, or just the bill?"
- "If something happened while you were abroad, who should handle your bank and phone?"
Make it clear these documents are about helping, not checking up. Many young adults are glad to sign once they see the papers give them control over who gets involved. Plan to revisit everything once a year, or after a move, a new school or a big life change.
A simple way to keep it all together
Keep copies of the signed documents in one place and make sure your young adult knows where they are; the documents themselves should be your state's official forms. For their medical information, the Family Health Binder: Fillable + iPad Edition ($29) keeps medicines, allergies, conditions, doctors and insurance in one binder, every page in English and Spanish.
