A power of attorney is a legal document that lets you name someone to handle money, property, or medical decisions on your behalf
A power of attorney is a written agreement where you give another person the legal authority to act for you. That person — called your agent or attorney-in-fact — can sign documents, manage bank accounts, sell property, or make medical choices depending on what powers you grant them. You remain in control: you decide exactly what your agent can do, when those powers start, and whether they end if you become unable to make decisions yourself.
The document does not require a lawyer to create, though having one review it costs less than most people expect. What matters is that it be signed, witnessed, and notarized according to your state's rules — requirements that vary. A power of attorney only works while you are alive; it ends at death, and your will or trust takes over from there.
Key Takeaways
- A power of attorney names someone to handle your finances, property, or medical decisions if you cannot or do not want to do so yourself.
- You can limit your agent's powers to specific tasks (like selling one house) or give broad authority over all your money and property.
- The document must follow your state's rules about witnessing and notarizing, or it will not be accepted by banks and other institutions.
- A durable power of attorney stays in effect even if you become mentally unable to make decisions, which is why most people choose this type.
- You can revoke a power of attorney at any time while you are mentally able to do so, and you should notify your agent and any institutions in writing.
The difference between a regular power of attorney and a durable one
A regular power of attorney ends automatically if you become unable to make decisions due to illness or injury. A durable power of attorney stays in effect even after you lose mental capacity — which is why nearly all seniors choose the durable version. The word "durable" straightforward means it survives your incapacity.
Some people create a springing power of attorney, which only becomes active if a doctor certifies that you can no longer make decisions. This appeals to people who want their agent to step in only if necessary. However, springing powers of attorney can create delays and confusion because banks and other institutions may question whether the triggering event has truly occurred. Most elder law attorneys recommend a durable power of attorney that takes effect when ready, paired with a trustworthy agent — because your agent has no incentive to use powers you have not given them.
What powers you can grant and what you should not include
You decide which specific powers to grant. Common choices include the right to access bank accounts, pay bills, manage investments, buy or sell real estate, file tax returns, and handle insurance. You can grant all of these or only a few. For example, you might give your agent power over your checking account but not your investment portfolio, or authority to sell your house but not to change your will.
There are limits to what a power of attorney can do. Your agent cannot change your will, create a new will, or make decisions about your will after you die. They cannot make gifts of your money or property unless you explicitly authorize it — and even then, most states limit how much can be given away. Your agent also cannot vote on your behalf or make decisions about your medical care unless you create a separate document called a healthcare power of attorney or medical proxy.
Do not use a power of attorney to try to override your own judgment later. For instance, you cannot write a power of attorney that says "my agent can do anything except sell my house" and then expect that restriction to hold if you become unable to object. Once you sign it, your agent has the powers you granted, and the only way to stop them is to revoke the document while you still have mental capacity.
Choosing an agent and what to discuss with them first
Your agent should be someone you trust completely — usually a spouse, adult child, or close family member. Some people name a professional, such as a bank trust department or an attorney, though this costs money. You can name more than one agent (called co-agents), but this can slow decisions if they disagree, so most people name one primary agent and a backup in case the first cannot serve.
Before you name someone, talk to them. Explain what you are asking them to do, what decisions they might face, and why you chose them. Many people say yes without understanding the responsibility — managing someone else's finances, paying their bills, and potentially making medical choices is time-consuming and stressful. Your agent should know they can ask for help from an accountant, attorney, or financial advisor, and that these costs usually come from your money, not theirs.
Make sure your agent knows where you keep important documents: your bank account numbers, insurance policies, property deeds, and the power of attorney itself. Some people keep a list in a safe deposit box or give a copy to their agent. Your agent cannot act without the actual signed document, so they need to know where it is.
How to create a power of attorney in your state
Each state has its own rules about how a power of attorney must be signed, witnessed, and notarized. Some states require one witness; others require two. Some require a notary; others do not. A few states have their own official forms. You can find your state's requirements through your state bar association's website or by calling your county clerk's office.
You have three main routes. First, you can use an online legal service that generates a document based on your state's rules — these cost between $50 and $150 and work well for straightforward situations. Second, you can hire an elder law attorney, which costs more (typically $300 to $500) but gives you a chance to ask questions and make sure the document fits your exact situation. Third, some states provide free or low-cost forms through the state bar association or legal aid offices.
Whichever route you choose, the document must be signed in front of witnesses and a notary public on the same day. Bring a photo ID. The notary will watch you sign and confirm that you understand what you are signing and are not being forced to do it. Banks and other institutions will ask to see the original signed document — photocopies usually are not accepted — so keep it somewhere safe and accessible.
When institutions may refuse to honor your power of attorney
Banks, investment firms, and insurance companies sometimes refuse to accept a power of attorney, even if it is valid. They may say the document is too old (though there is no legal age limit), does not match their form, or lacks information they want. This happens most often with older documents or when you try to use a power of attorney at a different branch of the same bank.
To avoid this, ask each institution — your bank, brokerage, insurance company, and mortgage lender — whether they have their own power of attorney form. Many do. You can sign their form in addition to your general power of attorney; it does not replace it, but it makes it harder for them to refuse. Keep a copy of the signed form with your general power of attorney.
If an institution refuses your valid power of attorney, ask to speak with the manager or legal department. You can also contact your state's attorney general's office or banking regulator to file a complaint. In most cases, persistence and a polite letter from an attorney will resolve the issue.
Revoking a power of attorney and what happens when you die
You can revoke a power of attorney at any time as long as you are mentally able to do so. To revoke it, sign a written revocation statement, have it notarized, and send copies to your agent and to any institutions that have a copy of the power of attorney. Keep the original revocation with your important documents.
A power of attorney automatically ends when you die. Your agent has no authority after that point. If your estate goes through probate, the court will appoint an executor (or you can name one in your will) to handle your property. If you have a living trust, the trustee takes over. Your power of attorney and your will or trust are separate documents that work together but serve different purposes.
Frequently Asked Questions
Do I need a lawyer to create a power of attorney?
No, but having one review it is often worth the cost. An attorney can make sure the document follows your state's rules, covers all the powers you want to grant, and is signed correctly so institutions will accept it. If your situation is straightforward — one agent, straightforward powers — an online legal service may be enough.
Can my agent use the power of attorney to give themselves money or property?
Only if you explicitly authorize it in the document. Even then, most states limit how much can be given away. Your agent has a legal duty called a fiduciary duty to act in your best interest, not their own. If they abuse this duty, you or your family can sue them to recover the money.
What happens if my agent dies or becomes unable to serve?
If you named a backup agent in the document, they take over automatically. If you did not name a backup, the power of attorney becomes invalid and you will need to create a new one naming a different agent. This is why naming a successor agent is important.
Can I have a power of attorney for medical decisions only?
Yes. A healthcare power of attorney (also called a medical proxy or healthcare proxy) is a separate document that gives someone authority to make medical decisions if you cannot. It does not give them power over your money or property. Many people create both a financial power of attorney and a healthcare power of attorney.
Will my power of attorney work in another state?
Usually yes, but some states are stricter than others about accepting out-of-state documents. If you move or own property in another state, ask an attorney in that state whether your power of attorney will be accepted there. You may need to create an additional one that follows that state's rules.
