You're 18. Your parents can no longer decide for you.

At 18, you are a legal adult in Arizona. HIPAA prevents your doctors from sharing medical information with your parents without your written authorization, and no one has legal authority to manage your finances or make healthcare decisions for you unless you've signed documents granting that authority. A healthcare directive and financial power of attorney are the two documents every Arizona adult should have, regardless of age or wealth.

Why young adults need a plan

Most people associate estate planning with older adults, significant wealth, or complicated family situations. That association causes millions of young adults to skip the most basic legal protections, exactly the ones they're most likely to actually need.

If you're in a car accident and can't communicate, who talks to your doctors? If you're studying abroad and a bank account needs to be managed, who has legal authority? If you're 22 and rent an apartment, own a car, and have a retirement account through your employer, those are assets. Without any planning, Arizona's intestacy laws decide who gets them.

The documents are simple. The conversation is short. The cost is minimal. The risk of not having them is not.

Healthcare directive and living will

A healthcare directive names someone (typically a parent, sibling, or trusted friend) to make medical decisions if you can't. It also records your wishes about life-sustaining treatment. Under Arizona law (A.R.S. § 36-3221), this can be a single document that covers both your healthcare agent designation and your treatment preferences.

Without this in place, your family may face delays or even court involvement before anyone can authorize treatment on your behalf. The document exists for exactly the situation where you cannot speak for yourself.

Financial power of attorney

A financial power of attorney authorizes someone to manage your finances (pay bills, access bank accounts, handle insurance claims) if you're incapacitated. Without this, your family would need to petition an Arizona court for a conservatorship, which is expensive, time-consuming, and public.

A HIPAA authorization often goes alongside these documents. It allows named individuals to access your medical records and speak with your healthcare providers so your family can get information quickly in an emergency.

College students leaving home

Parents are often surprised to learn they have no legal authority over their 18-year-old's medical or financial decisions. A healthcare directive and HIPAA authorization, signed before the student leaves for school, close that gap completely.

If you are an Arizona resident attending school in another state, Arizona documents are generally recognized. What matters most is having the signed documents available in an emergency, regardless of which state issued them.

Young professionals and digital assets

A 401(k), employer life insurance, and an HSA are all assets with beneficiary designations. If you haven't updated them, or never designated a beneficiary at all, the defaults may not match your wishes.

Cryptocurrency, online banking, investment apps, and social media accounts present another challenge. If no one knows your passwords and no one has legal authority to access your accounts, those assets can be effectively lost. A power of attorney and a basic digital asset plan address this.

A basic will if you have assets

If you own a car, have a bank account, or have a retirement plan through your employer, a simple will ensures those assets go where you want them (not where Arizona default law sends them).

Most young adults leave our office with the documents they need in a single appointment. The process typically involves one consultation and one signing, and most clients complete everything within a week or two.
