Power of Attorney vs Will: What’s the Difference?

People often assume a will covers everything. It doesn't. A will and a power of attorney solve two different problems — and the gap between them catches families out at the worst possible time.

The one-line difference

What a will does

A will takes effect when you die. It names who inherits your assets, appoints an executor to carry out your wishes, and names guardians for minor children. It has no power at all while you're alive. Learn how to write one here.

What a power of attorney does

A power of attorney (POA) lets someone you trust act on your behalf while you're alive — for example if illness or injury leaves you unable to manage your own affairs. There are two main kinds:

• Financial POA — lets your chosen person manage money, bills, property and accounts.
• Healthcare POA / directive — lets them make medical decisions if you can't.

Crucially, a POA ends at death — that's the moment the will takes over.

Why you need both

Without a POA, if you become incapacitated, your family may have to go to court to get authority to act — slow, costly and stressful. Without a will, the courts decide who inherits. Together, they cover you from incapacity through to death.

The piece both documents miss

Neither a will nor a POA tells anyone where your assets actually are. Your attorney-in-fact can't pay bills from an account they don't know exists; your executor can't distribute what they can't find. That's the job of a digital inheritance vault — and our estate planning checklist walks you through every document you need.
