Your Kid Turned 18. Here's What You Just Lost — And How to Get It Back
When my step-daughter started packing for college, we were deep in the weeds of shower caddies and extra-long twin sheets when someone made a joke about her being "officially an adult now." The laughter faded pretty quickly when we started working out what that actually meant, legally.
She had just turned 18. And as a Life Transition Attorney who has spent over two decades in courtrooms and mediation rooms, I knew exactly what that number meant — and it still caught me off guard.
At 18 and now a legal adult, my husband no longer had legal authority to speak with her doctor, see her college grades, or access her bank account if something happened to her, without her written permission. That realization turned into a family conversation. Then into a stack of documents. And now into this article — because if it caught me off guard, it's catching Santa Barbara County and Santa Ynez Valley parents off guard every single graduation season.
What "Legal Adult" Actually Means in California
Under California law, 18 is the age of majority. Full stop. The access and authority you've held over your child's healthcare, finances, and education since birth no longer applies to you — automatically or otherwise.
That's not a technicality. It shows up in real emergencies: a car accident near UC Santa Barbara, a mental health crisis at Cal Poly SLO, a billing dispute with a financial aid office when your student is overwhelmed and unavailable. Without the right documents in place, you are legally locked out — and the only path back in runs through a court proceeding that is expensive, slow, and emotionally brutal.
And while it requires an important conversation and ultimately it’s your child’s call, here are the four documents every 18-year-old in California can and in most circumstances should sign before they leave for college.
1. Advance Health Care Directive
California combines the Medical Power of Attorney and the Living Will into a single document called an Advance Health Care Directive, governed by California Probate Code §4700. This document names you (or another trusted agent) to make healthcare decisions if your child is incapacitated — and it captures their specific wishes for end-of-life care.
Think: your child is unconscious after a car accident. Without this document, the hospital cannot legally recognize you as their decision-maker, no matter how close you are or how far you drove to get there.
The Advance Health Care Directive also spells out what your child actually wants if the worst happens — whether they want life-sustaining treatment continued, when they want it withdrawn, and who they trust to carry out those wishes. These are not easy conversations. They're necessary ones.
2. HIPAA Authorization
The Advance Health Care Directive covers emergency decision-making. Day-to-day access to your child's medical records — speaking with their doctor, getting updates on an ongoing illness, reviewing test results — requires something separate: a HIPAA Authorization.
Under the Health Insurance Portability and Accountability Act of 1996, health information is protected the moment your child turns 18. No one — not even parents — can access it without written consent.
A signed HIPAA Authorization takes five minutes and costs nothing. It's also one of the most overlooked documents in this entire stack.
Privacy is important. This is a decision every person needs to make for themselves.
3. Durable Power of Attorney (Financial)
Under California Probate Code §4401, a Durable Power of Attorney authorizes a trusted agent — typically a parent — to manage a child's financial and legal affairs if they become incapacitated. That includes paying bills, managing bank accounts, handling tax matters, or applying for government benefits.
Without this document, accessing a simple checking account during a medical crisis can require a full conservatorship proceeding through the California probate courts — a process that takes months and can cost thousands of dollars in legal fees.
For a college student who may have student loans, a part-time job, a bank account, and a lease — this matters more than most families realize.
4. FERPA Release
This is the one most families have never heard of, and it's the one that most often surprises parents after the fact.
The Family Educational Rights and Privacy Act (FERPA) is a federal law that protects the educational records of students 18 and older. Once your child enrolls in college, you no longer have automatic access to their grades, financial aid status, billing account, enrollment records, or academic transcripts — unless they give you written permission or you claim your child as a dependent on your tax returns.
Every college and university maintains its own FERPA release form. It's free, it's fast, and it should be completed at or before orientation. Don't skip this one.
The Best Time to Handle This Is Now
Summer is the window. Your student is still home. Graduation energy makes these conversations feel timely rather than heavy — and getting it done before move-in day means you're not chasing signatures from three time zones away when something actually happens.
Families in Solvang, Buellton, Los Olivos, Lompoc, Goleta, Santa Ynez, and throughout Santa Barbara County: I've made it easy to take care of this in one session.
A Special Offer for May and June Graduates
Any family that comes in for a Life & Legacy Planning Session in May or June will receive all four documents — Advance Health Care Directive, Durable Power of Attorney, HIPAA Authorization, and FERPA Release — drafted for their graduating senior, as my gift.
I'll also schedule a complimentary 15-minute call directly with your student to walk them through what each document means. Not legal jargon — a real conversation about why this matters, what they're authorizing, and how to think about protecting themselves as they step into adulthood. For many of them, it's their first real introduction to the idea that legal protection isn't something you deal with later. It's something you put in place now.
As parents and step-parents, my husband and I try to instill the importance of understanding how the law applies and teach financial and legal literacy to our own four children in our blended family. These are teachable moments that make our family stronger and build trust across the generations.
To schedule your Life & Legacy Planning Session, visit TruceResolutions.com or call our Solvang office at 805-619-0640.
Your graduate is ready to fly. Make sure you have the legal documents in place to continue to be their trusted support system during their college years and beyond.
