Turning 18: The Legal and Financial Checklist Every Family Should Know
Turning 18: The Legal and Financial Checklist Every Family Should Know
Why an 18th birthday is also a legal turning point — and the documents that keep families connected when it matters most.
Throughout life there are certain milestone ages. The first of these is age 18. Turning 18 is more than just a birthday — it's a legal and financial transformation. This is the age at which you become responsible for your own financial and legal decisions, even if your parents are still paying for school, insurance, or living expenses. Once you turn 18, they no longer have the automatic legal authority to access or manage these matters on your behalf.
Hospitals, universities, and banks must follow strict privacy regulations. Without written permission, they may refuse to release information or allow a parent to get involved — even in an emergency. This can cause significant delays and stress during moments when fast action is critical.
Preparing the proper documents ahead of time helps avoid these roadblocks. This is especially important if your young adult is leaving home to attend a university out of state. Without these documents in place, your parents may be unable to obtain needed information in an emergency, and in a worst-case scenario, medical professionals may not be permitted to communicate with them at all.
Let's walk through the documents worth putting in order as your young adult moves into this next stage of life.
Why Turning 18 Matters
At age 18, individuals are considered legal adults in most U.S. states. Once they reach that age, 18-year-olds are permitted by law to:
- Vote in federal, state, and local elections
- Sign contracts
- Make their own medical decisions
- Sue, or be sued by, others
- Join the military without parental consent
- Open bank accounts and manage their own finances
This transition also means that parents lose automatic access to their child's medical, educational, and financial records — unless specific legal documents are signed in advance.
The Key Documents to Have in Place
Health Care Proxy (Medical Power of Attorney)
A health care proxy gives a young adult the ability to appoint someone they trust — often a parent — to make medical decisions if they're unable to communicate. This ensures their wishes are honored during a medical emergency, accident, or serious illness.
Without this document, medical providers must follow default protocols or seek court approval, which can slow decision-making considerably. Naming a health care agent provides peace of mind, allowing parents to step in quickly and confidently when it's needed most.
HIPAA Authorization for Medical Information
Under HIPAA privacy laws, medical professionals cannot share information with parents once a child becomes an adult. A HIPAA authorization allows specific individuals to receive updates, review records, and communicate directly with the healthcare team.
In an emergency, this form gives parents essential access to their child's condition and care plan. Without it, families may be left without even the most basic information.
Living Will for End-of-Life Choices
A living will outlines a young adult's preferences for end-of-life treatment, such as decisions about resuscitation, ventilators, feeding tubes, and organ donation. While these situations are rare for someone in their late teens, clear instructions can spare families from making painful decisions without guidance.
This document ensures loved ones understand — and follow — the young adult's wishes if a crisis arises.
Durable Financial Power of Attorney
A durable financial power of attorney authorizes a trusted person to manage financial matters if a young adult becomes incapacitated, or is simply unavailable — such as while traveling or studying abroad. Responsibilities may include:
- Paying rent, utilities, or other bills
- Accessing and managing bank accounts
- Handling insurance claims or tuition issues
- Communicating with landlords or service providers
Because this document remains effective even if the individual becomes incapacitated, it can prevent the need for a guardianship or conservatorship proceeding — which can be lengthy, public, and expensive.
FERPA Waiver for College Students
Under the Family Educational Rights and Privacy Act (FERPA), parents no longer have automatic access to academic information once their child turns 18 or begins college. A FERPA waiver allows a parent, or another trusted individual, to review grades, financial aid details, disciplinary records, and more.
This document is especially useful when families are working together on tuition planning or academic support.
Digital Asset Authorization
Much of a young adult's life exists online — from social media and email to cloud storage and financial apps. A digital asset authorization allows a chosen individual to access, manage, or close online accounts if the young adult becomes incapacitated or passes away.
Without this legal permission in place, families may struggle to retrieve important documents or secure financial information stored digitally.
Legacy Contact for a Smartphone
A legacy contact is a trusted person, chosen ahead of time, who can access a phone's account and retrieve important files — photos, documents, and messages — if the account holder passes away. Think of it as naming a digital executor for a smartphone. This is important for preserving memories, managing two-factor authentication, and securing important documents.

Financial Checklist
- Review Existing Accounts
Accounts opened under the Uniform Transfers to Minors Act (UTMA) or the Uniform Gifts to Minors Act (UGMA) transfer control to the child at age 18 or 21, depending on the state. Review these accounts ahead of time to ensure a smooth transition.
- Open New Bank Accounts
Encourage your child to open checking and savings accounts in their own name. This fosters financial independence and helps build good money management habits early on.
- Understand Credit
Educate your child about credit scores, interest rates, and responsible borrowing. According to Experian, the average credit score for 18- to 27-year-olds was 681 in 2024. Building good credit early can meaningfully impact future housing, employment, and loan opportunities.
- Register to Vote
Turning 18 also means becoming eligible to vote in federal, state, and local elections. Registering promptly ensures your young adult can participate as soon as an election comes around, whether at their home address or their new college address.
| Here's the Key Consideration • At 18, the law sees a young adult as fully responsible for their own medical decisions, financial accounts, academic records, and legal matters. • That means parents or guardians can't talk to their child's doctors without permission, access medical records, help resolve financial issues, speak with the bank, discuss grades or enrollment with the college, or manage bills and accounts if their child is abroad or incapacitated — unless the right documents are already in place. • This isn't about control. It's about protection. Emergencies happen, and when they do, families want someone they trust to be able to step in and help quickly. |
Special Considerations for Youth with Disabilities or in Foster Care
For youth with developmental disabilities, or those aging out of foster care, turning 18 can be especially complex. Legal guardianship, supported decision-making, and extended foster care benefits may all apply. Parents should consult with legal professionals or advocacy organizations to ensure proper planning is in place.
Why Planning Early Matters
Many families hesitate to discuss estate planning with teens and young adults, assuming these documents are only for older adults. In reality, planning at this stage is about empowerment — not pessimism. These documents allow young adults to decide who can help them, how decisions should be handled, and what protections they want in place.
Proactive planning also prevents unnecessary legal delays, ensuring families can act quickly when circumstances demand it.
