A power of attorney grants another person legal authority to act for you. The person you appoint is your agent or attorney-in-fact, and the document defines what they may do — pay bills, manage accounts, sign contracts, deal with property, handle tax filings. A general power grants broad authority; a limited one can be confined to a single transaction, like closing on a house while you are abroad.
The problem it solves is that ordinary joint access is not the same as legal authority. Banks, brokerages, insurers, and government agencies will not let a relative act on your behalf simply because they are family. Without a valid POA, the alternative is a guardianship or conservatorship proceeding: slow, public, expensive, and supervised by a court that does not know you.
The authority is significant, which makes the choice of agent the whole decision. This person can move your money. Selection should turn on judgment and integrity rather than birth order or proximity, and it is worth naming a successor in case your first choice is unavailable or unwilling when the time comes.
Note that a standard power of attorney ends if you become incapacitated — which is when most people assume it starts working. Making it durable is what keeps it alive through incapacity, and that distinction is the most consequential detail in the document.
Frequently asked
- Does a power of attorney let someone take my money?
- It gives them the legal ability to move it, which is exactly why the appointment matters so much. The agent owes you a fiduciary duty and must act in your interest, but that duty is enforced after the fact, usually by someone who noticed a problem. Practical protections work better than legal ones: choose someone trustworthy, consider limiting the scope, name a successor, and let a second family member know the document exists so the agent is not operating entirely unobserved.
- Does my power of attorney still work after I die?
- No. It ends at the moment of death, without exception. From that point authority passes to the executor named in your will, once the court appoints them. This catches families out regularly — an agent who has been managing a parent's finances for years suddenly has no authority at all, and there is often a gap before the executor is formally appointed. Planning for that gap is part of a complete plan.
- Will my bank accept the document?
- Usually, but not always without friction. Some institutions insist on their own forms, question documents signed years earlier, or route the request through a legal department that takes its time. You can reduce the risk by giving your bank a copy in advance and asking whether they require anything additional, rather than discovering an objection during an emergency.
