Key Documents For Kids Turning 18

When a child turns 18, their legal status shifts instantly—and that transition impacts far more than the right to vote or sign a contract. Parents who once had full access to school records, medical details, and financial information quickly discover that those privileges disappear under federal privacy laws. With the right documentation, however, young adults can maintain independence while still ensuring trusted support is available when needed.

This guide explains the key legal documents every young adult should consider. At Freeman & Bracey, PLC, our Goodlettsville estate planning attorneys help Middle Tennessee families put these protections in place so emergencies can be handled smoothly.

The Legal Shift at Age 18

Once a young adult reaches age 18, they become the sole legal authority over their medical, educational, and financial decisions. Even if a parent continues paying tuition or insurance premiums, that does not grant access to records or the ability to make decisions.

Healthcare providers, financial institutions, and colleges are legally obligated to protect privacy. Without written consent, they may be unable to release information—even in a crisis. This can delay decision-making and may force families to seek court intervention, such as emergency conservatorships in Tennessee.

In the event you have been appointed legal guardian by court order over a minor child with disabilities, it may be appropriate to convert the guardianship into a conservatorship to continue to handle their legal affairs. 

Preparing key legal documents eliminates these obstacles and ensures a family can act quickly if something unexpected happens.

Health Care Proxy (Medical Power of Attorney)

A health care proxy—commonly called a medical power of attorney—allows a young adult to appoint someone to make medical decisions if they lose the ability to communicate. This representative is often a parent or another trusted adult. 

Medical crises can arise without warning, even for teenagers and young adults. In those moments, having a designated decision-maker ensures providers know whom to contact and whose instructions to follow.

Without this document, Tennessee hospitals must rely on internal protocols or court direction, which can prolong urgent medical decision-making.

HIPAA Authorization for Medical Information

HIPAA laws strictly protect personal health information. Once a child turns 18, parents no longer have automatic access to medical updates, test results, or even confirmation of hospital admission.

A HIPAA authorization gives medical professionals permission to speak with designated individuals. This may include discussing diagnoses, sharing treatment updates, or confirming a patient’s location.

In emergencies, this document is vital. Without it, families may be left in the dark when their child needs help most.

Living Will for End-of-Life Preferences

A living will outlines a person’s wishes regarding life-sustaining medical treatment. Although end-of-life decisions may feel unrelated to youth, this document provides clarity if an unforeseen tragedy occurs.

A living will addresses topics such as mechanical ventilation, artificial nutrition, CPR, and organ donation. These instructions prevent confusion and reduce emotional burden on loved ones during difficult circumstances.

While rarely used for young adults, having clear guidance ensures decisions align with their values.

Durable Financial Power of Attorney

A durable financial power of attorney authorizes a chosen individual to manage financial responsibilities if the young adult becomes incapacitated or temporarily unavailable.

Tasks may include:

• Managing bank accounts and online financial tools
• Paying rent, tuition, or household bills
• Handling insurance matters or filing claims
• Communicating with landlords or service providers
• Managing student loan or scholarship-related obligations

The “durable” designation ensures the authority remains valid even during incapacity. Without this document, families may need court-approved conservatorships—a time-consuming and costly process under Tennessee law. This document is especially useful for students studying abroad or navigating serious illness.

FERPA Waiver for College Students

The Family Educational Rights and Privacy Act (FERPA) prevents colleges from releasing educational records without student permission. Academic records, financial aid information, and disciplinary reports are all protected.

A FERPA waiver authorizes the school to communicate with parents or other trusted individuals. For families assisting with academic planning or financial obligations, this waiver streamlines communication and eliminates barriers.

Without it, universities cannot legally share even basic information.

Digital Asset Authorization

Young adults often store significant personal and financial information online—from social media and email to digital subscriptions and cloud accounts. Accessing these accounts after incapacity or death can be extremely difficult.

A digital asset authorization allows a designated person to access important online accounts or manage digital property. This may involve securing financial data, closing social media profiles, or retrieving personal documents.

Without permission, family members may struggle to access critical information or safeguard sensitive digital assets.

Why Early Planning Is Beneficial

Many families believe estate planning is unnecessary for young adults. However, these documents are not about anticipating worst-case scenarios—they are about ensuring support and avoiding legal delays.

When these forms are signed, the young adult maintains full control over who may act on their behalf and under what circumstances. This protects their autonomy while ensuring trusted individuals can step in quickly if an emergency arises.

Proactive planning also prevents the need for emergency legal proceedings, which can be emotionally and financially stressful.

Supporting Your Young Adult’s Transition Into Adulthood

Turning 18 represents a major milestone. With new independence comes the responsibility to plan for unexpected circumstances. A complete set of documents—health care proxy, HIPAA authorization, living will, durable financial power of attorney, FERPA waiver, and digital asset authorization—forms a strong foundation for responsible adulthood.

At Freeman & Bracey, PLC, our Goodlettsville estate planning team assists families across Middle Tennessee in preparing these essential protections. If your child is entering college or taking their first steps into adult life, now is an ideal time to put these measures in place.
