Most estate planning conversations focus on wills and trusts — documents that take effect when you die. But there's an equally important category of documents that take effect while you're alive: powers of attorney. These documents authorize someone else to act on your behalf when you can't act for yourself.
Two types you need to understand
Financial power of attorney. This document authorizes a person you name — called your agent or attorney-in-fact — to manage your financial affairs. They can pay bills, manage bank accounts, file taxes, sell property, and handle other financial matters on your behalf.
Healthcare power of attorney (also called a healthcare proxy or medical power of attorney). This authorizes your agent to make medical decisions on your behalf if you're unable to make them yourself — if you're unconscious, severely ill, or otherwise incapacitated.
These are separate documents, and you don't have to name the same person for both. Many people name a spouse for healthcare decisions and an adult child or trusted friend for financial ones.
What 'durable' means
A standard power of attorney automatically becomes invalid if you become incapacitated. This is exactly backwards from what you need — you most need someone to act for you when you're incapacitated.
A "durable" power of attorney remains effective even if you lose capacity. This is the type you want for estate planning purposes. When people refer to a power of attorney in the context of estate planning, they almost always mean a durable power of attorney.
A "springing" power of attorney only activates under specific circumstances — typically when two physicians certify that you're incapacitated. This sounds appealing but can cause practical delays when time matters. Most estate planning attorneys recommend an immediately effective durable power of attorney over a springing one.
Why it matters more than people realize
Without a durable power of attorney, if you become incapacitated — from an accident, illness, or cognitive decline — your family may have no legal authority to manage your finances. Even a spouse often can't access accounts held only in your name.
The alternative is a court-supervised conservatorship or guardianship proceeding. This process is public, expensive (attorneys, court fees, ongoing oversight), and slow. It can take months to establish. During that time, your bills may go unpaid, your investments unmanaged, and your affairs in disarray.
A properly executed durable power of attorney avoids all of this. It gives your chosen agent immediate authority to act, without court involvement.
Choosing your agent
Your agent should be someone you trust absolutely — they will have significant power over your finances and/or health. Consider:
Financial agent: someone organized, financially literate, and scrupulously honest. The power to manage someone's finances is a power that can be abused. Choose someone with a strong track record and, ideally, no potential conflict of interest.
Healthcare agent: someone who knows your values and will advocate for them, even under pressure from family members or medical professionals who disagree. This person needs emotional fortitude as much as organizational skill.
Always name a backup agent in case your first choice is unavailable.
The living will (advance directive)
A related document is the living will — also called an advance healthcare directive. This is not a power of attorney; it doesn't authorize anyone to act on your behalf. Instead, it records your specific wishes about end-of-life medical treatment: whether you want to be kept on life support, your preferences around resuscitation, and similar decisions.
A living will works alongside your healthcare power of attorney. Your healthcare agent can use it to understand your wishes; medical providers can consult it when your agent is unreachable. Together, these documents give you the most complete expression of your healthcare wishes.
A note on will.com
will.com currently generates last wills and testaments. Powers of attorney and advance directives are complex documents with highly variable state requirements, and we're working to add them. In the meantime, if you need these documents, consult an estate planning attorney in your state — or look into state-specific forms published by your state bar association.
