POA stands for power of attorney. It is a legal document in which one person, called the principal, gives another person, called the agent, authority to make decisions or take actions on their behalf. Depending on how the document is written, a power of attorney can cover financial matters, healthcare decisions, or both, and it is one of the core tools in estate planning because it lets someone you trust step in if you cannot manage your own affairs.
How a Power of Attorney Works
The arrangement has two sides. The principal grants the authority. The agent, sometimes called an attorney-in-fact, receives it. You must have the mental capacity to understand what you are signing at the moment you create the document, meaning you grasp the scope of authority you are handing over and the consequences of doing so.
Your agent does not need to be a lawyer. Most people name a spouse, an adult child, a trusted friend, or a professional advisor. Reliability is what matters, because the relationship is fiduciary. Under the Uniform Power of Attorney Act, which a majority of states have adopted, an agent must act in your best interest, act in good faith, stay within the authority you granted, avoid conflicts of interest, and keep records of all transactions made on your behalf.1Uniform Law Commission. Uniform Power of Attorney Act – Section 114
An agent who violates these duties can be removed by a court, sued for losses, or face criminal charges in serious cases involving theft or exploitation. You can also revoke the power of attorney at any time, as long as you still have the capacity to do so.
Financial Power of Attorney vs. Healthcare Power of Attorney
There are two broad categories, and they cover very different ground. A financial power of attorney authorizes your agent to handle money and property: paying bills, managing bank accounts, filing tax returns, buying or selling real estate, and similar tasks. A healthcare power of attorney authorizes your agent to make medical decisions when you cannot communicate your own wishes.
These are separate documents. A financial POA gives no authority over your medical care, and a healthcare POA gives no access to your bank accounts. If you want one person to handle both, you need to sign both documents.
A healthcare POA also carries a privacy consequence. When one is in effect, the named agent becomes your “personal representative” under HIPAA, with the same right you have to access your medical records, including mental health information.2HHS.gov. Personal Representatives A provider may refuse to treat someone as your personal representative only if the provider reasonably believes you may be subject to abuse or endangerment by that person.3HHS.gov.

Types of Power of Attorney
Beyond the financial/healthcare split, powers of attorney vary in how much authority they grant and how long they last.
General vs. Limited
A general power of attorney gives your agent broad authority to handle virtually any financial or legal matter on your behalf. A limited (or special) power of attorney restricts your agent to one or more specific tasks, such as signing closing documents on a single real estate sale or managing one investment account. Once that task is done, the authority ends.
Durable vs. Non-Durable
Durability decides what happens if you lose mental capacity. A non-durable power of attorney automatically terminates when you do. That makes it useful for short-term arrangements, such as authorizing someone to handle finances while you travel, but not for long-term planning.
A durable power of attorney stays in effect even after you become incapacitated. The document must include specific language, typically along the lines of “this power of attorney shall not be affected by subsequent disability or incapacity of the principal.” Without that language, most states treat the document as non-durable by default. For most people, the durable version is the practical choice, because its whole purpose is to cover the situations when you cannot act for yourself.
Springing Power of Attorney
A springing POA sits dormant until a triggering event occurs, usually a physician’s written determination that you lack capacity. Until that happens, your agent has no authority at all.
This sounds protective, and it can create problems. Activating it requires coordination among your healthcare agent, your physicians, and your financial agent. A doctor has to make a formal determination, medical information has to be released to the right parties, and banks may demand specific documentation before recognizing the agent’s authority. During that window, urgent matters like mortgage payments, tax filings, and insurance claims may go unaddressed. Many estate planning attorneys recommend a durable POA with trusted agents over a springing one for exactly this reason.
What an Agent Cannot Do
Even the broadest power of attorney has limits.
- An agent cannot create, modify, or revoke your will. That authority is personal to you and cannot be delegated.
- Every power of attorney terminates automatically at the principal’s death. After that, your agent has no authority to manage or dispose of your property; control passes to the executor named in your will or an administrator appointed by a probate court.
- Unless the document specifically grants gift-making authority, your agent cannot give away your money or property, including to themselves. The Uniform Power of Attorney Act treats gifts and changes to beneficiary designations as actions that require an express grant.4Uniform Law Commission. Uniform Power of Attorney Act – Section 201
- An agent must stay within the authority granted. A limited POA to sell your house does not let that agent open credit cards in your name.
How to Create a Power of Attorney
Before you draft anything, gather the full legal names and current addresses of your chosen agent and at least one successor agent. The successor steps in if your primary agent is unable or unwilling to serve. Decide which powers you want to grant. Common ones include managing bank accounts, paying bills, filing tax returns, handling insurance claims, and buying or selling real estate.
Many states publish standardized power of attorney forms through their bar associations or court websites. Using one of these forms helps ensure the document contains the language your state requires. If you have significant assets, business interests, or complicated family circumstances, working with an attorney is worth the investment. Attorney fees for drafting a straightforward POA typically run about $200 to $500, and more for complex arrangements.
Nearly every state requires the principal’s signature to be notarized. The notary verifies your identity and confirms you are signing voluntarily. Most states also require one or two disinterested witnesses, who generally cannot be the named agent or anyone who benefits from the document. Notary fees for an acknowledgment usually fall between $2 and $25 per signature. If the document authorizes real estate transactions, you may need to record it with the county recorder’s office where the property is located, which typically costs $5 to $50 depending on the number of pages.
How a Power of Attorney Ends
You can revoke a power of attorney at any time, for any reason, as long as you still have the capacity to do so. The usual steps:
- Sign a written revocation and have it notarized.
- Deliver a copy to your agent. Certified mail with return receipt creates a paper trail.
- Send copies to every bank, financial institution, healthcare provider, or other organization that holds a copy of the original. If the original was recorded with a county office, record the revocation there too.
Destroying the original is not always enough, because copies may still be in circulation. Until third parties receive notice, they may continue to honor the old document in good faith.
A power of attorney also ends automatically in several situations. It terminates immediately at the principal’s death, regardless of what the document says. It ends if the agent dies or becomes incapacitated and no successor is named. A non-durable POA ends when the principal loses capacity. A court can revoke a POA or remove an agent who is acting improperly. And a limited POA ends when the specific transaction it covered is complete.
If a third party relies on a POA in good faith without knowing the principal has died, actions taken are generally still valid. But the agent must stop acting as soon as they learn of the death, since authority over the estate shifts to the executor or personal representative appointed through probate.
