How Is a Power of Attorney Different from a Healthcare Directive?
Last reviewed: June 2026
A power of attorney and a healthcare directive are two separate legal documents that address different types of decisions when you are unable to make them yourself. Most people need both — and most people have neither until a crisis forces the issue.
What a Power of Attorney Does
A power of attorney is a legal document that authorizes another person — your agent — to make financial and legal decisions on your behalf. A durable power of attorney remains effective even if you become mentally incapacitated, which is precisely when it is most needed.
Your agent under a power of attorney can pay your bills, manage your bank accounts, file your taxes, manage your investments, sell real estate if authorized, and handle any other financial matters you specify. The scope of authority is defined by the document — you can make it broad or limit it to specific types of transactions.
Without a durable power of attorney, if you become incapacitated, your family may need to go to court to establish a conservatorship — a court-supervised arrangement that gives someone legal authority over your finances. This process is expensive, time-consuming, and public.
What a Healthcare Directive Does
A healthcare directive — also called an advance directive or living will — specifies your medical treatment preferences if you become unable to communicate them. It addresses decisions like whether you want life-sustaining treatment if you are terminally ill, whether you want artificial nutrition and hydration, and your preferences regarding organ donation.
A healthcare proxy or healthcare power of attorney — sometimes included within the same document as a living will — names a specific person to make medical decisions on your behalf. This person is your healthcare agent or proxy, and their authority is separate from the agent named in your financial power of attorney.
Why You Need Both
Financial decisions and medical decisions require different types of authority and are often made by different people. You might name a financially sophisticated sibling as your financial agent and a spouse who knows your medical values as your healthcare proxy. Having both documents ensures that both types of decisions can be made by the right person without court involvement.
Frequently Asked Questions
Can the same person be my financial agent and my healthcare proxy?
Yes. Many people name the same trusted person for both roles. However, naming different people for each role is also common — particularly when different family members have different strengths or when you want to separate financial and medical decision-making.
Does a power of attorney work after I die?
No. A power of attorney — including a durable power of attorney — terminates at death. After death, your executor named in your will takes over management of your estate. A power of attorney only covers decisions made during your lifetime.
Can I revoke a power of attorney?
Yes, as long as you are mentally competent. To revoke a power of attorney, you should execute a written revocation, notify your agent, and notify any institutions — banks, financial advisors — who may have relied on the power of attorney.
What happens if I become incapacitated without a durable power of attorney?
Your family would need to petition the court for a conservatorship — a court-supervised arrangement giving someone authority over your finances. This is expensive, time-consuming, public, and requires ongoing court oversight. A durable power of attorney avoids this entirely.
At what age should I have a power of attorney and healthcare directive?
At 18. Once you turn 18, your parents no longer have legal authority to make decisions on your behalf. College students, young adults, and anyone without these documents is one accident away from leaving their family unable to help them without going to court.
