KEY TAKEAWAYS
- At 18, your legal authority as a parent ends.
- Medical, financial, and school information can suddenly become off-limits.
- Unexpected problems aren’t always emergencies.
- A little planning today can prevent major stress tomorrow.
- The best gift you can give your young adult is being prepared.
For years, you’ve been the one signing permission slips, scheduling doctor appointments, talking with teachers, and making important decisions for your child. Then one day, they turn 18.
Whether they’re heading off to college, starting a career, joining the military, or simply moving into their first apartment, something significant changes overnight. Legally, they are now adults—even if you’re still helping pay tuition, covering them on your health insurance, or reminding them to do their laundry.

For years, you’ve been the one signing permission slips, scheduling doctor appointments, talking with teachers, and making important decisions for your child. Then one day, they turn 18.
Many parents are surprised to learn that they no longer have the legal right to step in on their child’s behalf when the unexpected happens.
Sometimes it isn’t a medical emergency at all—it’s everyday life. Imagine your son is away at college during final exams. His debit card is lost, his account is temporarily locked, and the bank where he opened the account is back home. At the same time, a study abroad program requires payment by the end of the day to secure his spot. You have the funds and want to help, but without the proper legal authority, the bank may be unable to discuss the account or allow you to act on his behalf.
Of course, emergencies can happen too. If your daughter is hospitalized while away at school, healthcare providers generally cannot automatically share medical information with you simply because you’re her parent. Once a child turns 18, privacy laws protect their information unless they have authorized someone to receive it.
Fortunately, a little planning can make all the difference.
A Healthcare Power of Attorney allows your child to name someone they trust to receive medical information and make healthcare decisions if they’re unable to do so themselves.
A Financial Power of Attorney gives that trusted person the authority to assist with financial matters, such as banking, paying bills, or handling insurance issues if needed.
Parents of college students should also be familiar with the Family Educational Rights and Privacy Act (FERPA). Once a student turns 18, colleges generally cannot share grades, financial aid information, or disciplinary matters without the student’s permission. Completing a FERPA release can help ensure you’re able to assist when questions or unexpected situations arise.
Watching your children spread their wings is one of life’s greatest joys. While you can’t protect them from every challenge they’ll encounter, you can help prepare them for adulthood through thoughtful conversations and a few important legal documents that provide clarity when it’s needed most.
Estate planning at 18 isn’t about taking away a young adult’s independence—it’s about empowering them to make their own decisions, including choosing who they trust to step in if the unexpected happens. It’s one of the first truly adult decisions they can make. As your child begins this exciting new chapter, take the opportunity to prepare together. It’s not about expecting something to go wrong; it’s about giving your family the confidence to navigate whatever life brings, together.
