When Your Child Turns 18: The Legal Documents Parents Often Need Before College

There’s a strange moment many parents feel before college. You’re still buying the sheets, checking the dorm list, reminding them to take medicine, and helping them think through meal plans. But legally, something has changed: your child is now an adult.

That doesn’t mean your role disappears, just that the way you support them may need to be documented. Before college begins, a few legal documents can help your family stay calm, clear, and prepared.

Why turning 18 changes what parents can do

In California, a minor is someone under 18. Once your child turns 18, they’re legally treated as an adult in many important ways. That can surprise loving, involved parents.

You may still be paying tuition, be listed as the emergency contact, and your child may still call you first when something goes wrong, but legal authority doesn’t always follow the emotional reality of the relationship. If your child is injured, hospitalized, overwhelmed by a financial issue, or unable to manage an urgent matter, you may need written authority to step in smoothly.

The goal is to give your adult child the ability to choose who can help if help is needed.

The health care documents to discuss before college

The first conversation is usually about health care.

California’s advance health care directive form allows a person to give instructions about their own health care and name someone else to make health care decisions for them. The form also allows the person to name alternate agents if the first choice is not available.

For a college student, that can matter quickly.

Imagine your child is away at school and has a serious accident, illness, or mental health emergency. You may want to speak with doctors, understand what is happening, and help make decisions if your child can’t speak for themselves.

A health care directive can name a parent or another trusted adult as the health care decision-maker. A HIPAA authorization can also help address access to medical information. Simply, an individual can direct a covered health care provider or health plan to send protected health information to a family member when the request is written, signed, and identifies the person and where the information should go.

These documents are not only for older adults; they’re practical tools for any adult, including an 18-year-old preparing to live away from home.

The financial document that can prevent a practical mess

The second document to discuss is a durable power of attorney.

In California, a durable power of attorney allows a person to name another person to act as attorney-in-fact, and it can include language showing that the authority continues even if the person later becomes incapacitated.

For a college student, this may help with everyday problems that become harder from a distance. A parent might need to help with a bank issue, sign housing-related paperwork, manage a bill, resolve an insurance question, or handle financial matters if the student is temporarily unable to act.

It’s one of those documents families hope they never need, but when they do need it, they’re usually grateful it already exists.

What parents should not assume

Parents often assume that schools, doctors, and financial institutions will recognize them immediately because they are the parent. That’s not always how it works.

Under FERPA, rights that previously belonged to the parent transfer to the student. Written consent is generally required before an educational institution discloses personally identifiable information from education records, unless an exception applies, meaning families shouldn’t rely on assumptions during a stressful moment.

The same practical caution applies to financial institutions. They will honor a power of attorney in the same way, so it’s important to think through the specific accounts and institutions involved.

The best time to address these details is before move-in day, not during an emergency.

Turning 18 is a milestone for your child; it’s also a planning moment for your family

The right documents can help your adult child keep their independence while giving trusted people the ability to help when help is truly needed. A health care directive, HIPAA authorization, and durable power of attorney can turn a confusing situation into one with clearer options and calmer next steps.
