Your Kid Is Turning 18 and Heading to College: The Estate Planning Step Most California Parents Miss
You bought the twin XL sheets. You survived the campus tour. You’ve about had it with the parent group created on Facebook because what do you mean you’re asking how your child is supposed to eat if they don’t like what’s in the food court.
Here is the part of the college checklist nobody tells you about: the day your child turns 18, you lose the legal authority to make decisions for them. All of it. Overnight.
That is not a scare tactic. That is just how the law works. And for California parents sending a kid off to college, it creates a gap that is surprisingly easy to fix and surprisingly painful to ignore. This post walks through exactly what changes at 18, the three documents every college-bound student needs before move-in day, and why this season of life is also the perfect moment to dust off your own estate plan.
What Actually Changes When Your Child Turns 18
In the eyes of the law, your 18-year-old is an adult. A full, independent, legally complete adult. The fact that you pay their tuition, their phone bill, their health insurance, and their car insurance does not matter. The fact that they still call you to ask how to do laundry does not matter either.
Here is what that means in practice. If your college student is in an accident two states away, the hospital does not have to tell you anything. You can call around to find them, but you’ll likely be met with an “I’m sorry I can’t provide that information” at every turn. HIPAA privacy rules apply to your adult child the same way they apply to any stranger walking through the emergency room doors. The nurse on the phone is not being difficult. She is following federal law.
The same wall goes up on the financial side. You cannot access their bank account, even the one you opened for them in middle school if it has been converted to their name. You cannot negotiate with their landlord, deal with their car registration, handle an insurance claim, or resolve a billing dispute on their behalf unless you’re legally tied to that process like co-signing on the lease or co-owning the car.. If they are studying abroad and something goes wrong with their finances at home, you are a spectator.
Even their education is off limits. Under FERPA, the federal student privacy law, the university cannot share grades, academic standing, or disciplinary records with you without your student’s written consent. You can pay $95,000 (looking at you USC!) a year in tuition and have no legal right to know whether your student is passing.
Most families discover this gap at the worst possible moment, standing in a hospital hallway being told politely that they have no legal standing to make decisions for the kid they raised. It is an awful feeling, and it is completely preventable.
The Three Documents Every College-Bound 18-Year-Old Needs
The fix is simple, and it is one of the most affordable pieces of estate planning a family will ever do. Three documents close the gap.
Advance Health Care Directive. This lets your student name the person they want making medical decisions if they cannot make them themselves, which for most college students is a parent. It also documents their wishes about treatment so that nobody is guessing during an emergency. If your student is attending school out of state, the directive should be drafted with that in mind so it travels well. A good directive works in a dorm in California, a hospital in Arizona, or in Panama City Beach, Florida after a particularly heinous Spring Break trip.
HIPAA Authorization. This is the document that lets doctors and hospitals actually talk to you. People are often surprised that this is separate from the health care directive, but the two do different jobs. The directive gives you authority to decide. The HIPAA authorization gives you access to information. Without it, even a parent named as a health care agent can run into walls trying to get basic updates, because the directive is only activate when your student is incapacitated. The HIPAA release works the moment it is signed.
Financial Power of Attorney. This lets your student authorize you to handle financial and legal matters on their behalf. Bank accounts, leases, insurance claims, tax filings, financial aid paperwork, a fender bender involving the car that is titled in their name. College students are busy being college students and still learning how to be adults. A financial power of attorney means a parent can step in and handle the adult logistics when needed, without anyone needing to involve a court.
A quick word about what these documents are not. They do not take away your child’s independence, and they are not parents reclaiming control. They are your child, as a legal adult, choosing who gets to help them and under what circumstances. Signing them is a pretty good first adult decision. Most students, once they understand what the documents do, are genuinely glad to have them.
These documents are quick to prepare and most families can have everything signed in a single visit. You can learn more about how we put these together on our estate planning services page.
The Conversation to Have Before Move-In Day
Documents work best when everyone understands them, so have the conversation as a family. Explain to your student that these are their documents, naming their choices. Walk through what would happen without them: the hospital that cannot share information, the bank that cannot take your call, the lease problem that has to wait until winter break.
Then talk about logistics, because logistics matter in an emergency. Where will the originals live? Who keeps copies? Many families give a copy to the student for their records, keep the originals at home, and store digital copies somewhere both parent and student can reach from a phone. If your student has a campus health center, ask whether they will keep a copy of the health care directive or HIPAA on file. Many will.
And if your student is over 18 and resistant to the idea, do not force it, but do not drop it either. Share a story. Every estate planning attorney has one about the family that waited. The documents only work if they exist before the emergency starts.
This Is Also Your Reminder, Parents
Here is the thing about this season of life: while you are setting up documents for your student, it is the perfect moment to look at your own plan. We see it constantly. Parents come in for college documents and leave realizing their own estate plan has not been touched since the kids were in elementary school.
If your plan was written when your kids were little, it probably does not match your life anymore. Ask yourself honestly whether your freshman should receive their entire inheritance during orientation week. Most parents, after a brief pause, decide on a different answer, like distributions staged at 25, 30, and 35, with a trustee managing things in the meantime.
Maybe your assets have changed, you have refinanced your home (which sometimes pulls a house out of a trust without anyone noticing), or your family has grown or changed shape. An estate plan is a living set of documents, and the college transition is one of the natural checkpoints in life to review it.
And if you never created a plan at all, you are not alone, and it is not too late. But the years when your kids are transitioning into adulthood are exactly when an outdated or missing plan causes the most confusion, because your family is now a mix of minor children, adult children, and shifting responsibilities.
What Most Families Miss
A few things we see all the time with college families.
Out-of-state schools. If your student is attending school outside California, their documents should be drafted to travel well. Each state has its own forms and quirks, and while properly drafted California documents are generally honored elsewhere, drafting with portability in mind avoids friction at the moment you least want friction, especially when it comes to reproductive care.
The car and the bank account. If the car your student drives is titled in their name, or they have accounts in their own name, the financial power of attorney matters even more. A parent listed on a joint account has access to that account, but nothing else. The power of attorney covers everything else.
Younger siblings at home. If you still have minor children, your own plan needs standalone temporary and permanent guardianship nominations, separate from your will and trust, so the people you choose can step in immediately if something happens to you. Sending one kid to college does not finish the job for the others. Your guardianship nomination should tell the story of your younger kids, the people who matter to them, and how you want them raised, so a guardian is never guessing.
Waiting for a problem. These documents only work if they exist before you need them.The alternative is a court process at the worst moment of your life.
