What Powers You Give When You Sign
A power of attorney is a legal document that lets you give another person the right to act on your behalf in financial, medical, or legal matters. The person you name—called your agent or attorney-in-fact—can then sign documents, move money, make healthcare decisions, or handle property in your name, depending on what you write into the document. You stay in control of what they can and cannot do by choosing which powers to grant them.
The specific actions your agent can take depend entirely on the language in your document. You might give them permission to handle only your bank accounts, or you might give them broad authority over all your finances. You might limit their power to a single task—selling one piece of property, for example—or you might let them act on almost anything. The document spells out the boundaries.
Key Takeaways
- Your agent can only do what the power of attorney document explicitly allows them to do; they have no authority beyond those written powers.
- Financial powers typically include managing bank accounts, paying bills, selling property, and handling investments, but only if you grant them.
- Healthcare powers let your agent make medical decisions if you cannot, such as choosing treatments or accessing your medical records.
- You can make the power of attorney effective when ready or only if you become incapacitated, and you can revoke it at any time while you are mentally able.
- Your agent must act in your best interest and keep records of what they do with your money and property.
Financial Powers Your Agent Can Exercise
If you grant financial powers of attorney, your agent can typically handle money and property matters in your name. This usually includes depositing and withdrawing money from your bank accounts, paying your bills, collecting money owed to you, and managing your investments or retirement accounts. They can also buy, sell, or refinance real estate on your behalf, file your taxes, and handle insurance claims.
The scope varies widely depending on what you authorize. Some people give their agent power over everything—all accounts, all property, all financial decisions. Others limit it sharply: "You can only access my checking account to pay my mortgage and utilities" or "You can sell my rental property but nothing else." The document must be specific enough that banks and other institutions know what your agent is allowed to do.
Your agent cannot use these powers for their own benefit unless you explicitly allow it. They cannot take money from your accounts for themselves, cannot sell your property and keep the proceeds, and cannot invest your money in their own business. If they do, they have broken the law and can be sued. They must keep records of what they spend and be ready to show you or a court where your money went.
Healthcare and Medical Decisions
A healthcare power of attorney (sometimes called a healthcare proxy or medical power of attorney) lets your agent make medical decisions for you if you cannot make them yourself. This includes choosing doctors, approving or refusing treatments, deciding whether to use life support, and accessing your medical records. Your agent can also sign consent forms for surgery, admit you to a hospital or nursing home, and direct your end-of-life care.
This power only activates when you are unable to communicate your wishes—due to unconsciousness, severe illness, dementia, or another condition that prevents you from making decisions. While you are able to make your own medical choices, your agent has no authority, even if the document is already signed. You remain in charge of your own healthcare.
Your agent must follow any written instructions you left behind, such as a living will or specific wishes about life support. If you have not left written instructions, they must make decisions based on what they believe you would have wanted, or based on your best medical interest if your wishes are unknown.
Limited Powers vs. General Powers
You can write a power of attorney that is limited to a single task or general and broad. A limited power of attorney might say: "My agent can only sell my house at 42 Oak Street and deposit the proceeds into my savings account." Once that task is done, the power ends. Limited powers are useful when you need someone to handle one specific thing—closing on a property while you are out of the country, for example—but you do not want to give them broader authority.
A general power of attorney gives your agent broad authority over most or all of your financial and legal matters. They can act on almost anything without asking your permission first. This is useful if you are becoming ill and need someone to manage everything, or if you are traveling and want someone to handle all your affairs while you are gone. The tradeoff is that you are giving up more control.
Many people use a middle ground: they grant powers over specific categories. For example, "You can manage all my bank accounts and pay my bills, but you cannot sell any real estate" or "You can handle my investments but not my business." The document should be as specific as possible so that banks, brokers, and other institutions understand exactly what your agent can do.
When the Power of Attorney Takes Effect
You can choose whether the power of attorney is effective when ready or only if you become incapacitated. An when ready power of attorney takes effect as soon as you sign it. Your agent can start acting on your behalf right away, even if you are healthy and able to make decisions yourself. This is useful if you need help managing your affairs now—because you are traveling, working long hours, or dealing with a temporary situation.
A springing power of attorney does not take effect until a specific event happens, usually when you become incapacitated. The document will say something like "This power of attorney becomes effective only if my doctor certifies that I am unable to manage my affairs." Until that event occurs, your agent has no authority. This gives you more control in the present—your agent cannot act unless you truly cannot—but it can create delays if you become suddenly incapacitated and no one is when ready available to certify it.
Springing powers of attorney are more complicated to set up and can cause problems if institutions question whether you are actually incapacitated. Many people find an when ready power of attorney simpler, especially if they trust their agent. You can always revoke it if circumstances change.
What Your Agent Cannot Do
Your agent cannot do anything that is not written into the power of attorney document. If the document does not mention real estate, they cannot sell your house. If it does not mention your business, they cannot make business decisions. If it does not mention your healthcare, they cannot make medical choices. The document sets the boundaries, and your agent must stay within them.
Your agent also cannot change your will, create a new will, or make gifts of your money or property to themselves or others—unless you explicitly give them that power in writing. They cannot use your money for their own purposes. They cannot take out loans in your name. They cannot change the beneficiaries on your life insurance or retirement accounts. They cannot adopt children or make decisions about your children's custody or upbringing.
If your agent violates these limits or acts against your interests, you can revoke the power of attorney when ready (if you are still able to), and you can sue them for damages. Family members or other interested parties can also ask a court to remove your agent if they are abusing their power.
Revoking or Changing the Power of Attorney
You can revoke a power of attorney at any time as long as you are mentally able to understand what you are doing. You do not need a reason, and you do not need your agent's permission. straightforward sign a written revocation document, have it notarized (depending on your state), and give copies to your agent, your bank, your doctor, and anyone else who has a copy of the original power of attorney.
If you want to change what your agent can do without revoking the whole document, you can amend it. This requires the same formality as creating a new one—usually a notarized signature. It is often simpler to revoke the old document and create a new one with the powers you want.
If you become incapacitated and did not create a power of attorney, your family cannot straightforward step in and act on your behalf. They will have to go to court and ask a judge to appoint a conservator or guardian, which is more expensive, more public, and takes longer. Creating a power of attorney while you are able to do so lets you choose who you trust to act for you, rather than leaving it to a judge.
Frequently Asked Questions
Can my agent use my power of attorney to give money to themselves?
Only if you explicitly give them that power in the document. Otherwise, no. If they take money without permission, they are breaking the law and can be sued. Your agent must act in your best interest, not their own, and must keep records of everything they spend.
Does my agent have to tell me what they are doing with my money?
Yes. Your agent must keep records of all transactions and be ready to show you or a court where your money went. If you ask to see the records and they refuse, that is a sign of abuse. You can revoke the power of attorney and take legal action.
What happens to the power of attorney when I die?
It ends when ready. Your agent has no authority over your estate after death. Your will and the probate process take over instead. If you did not create a will, your state's laws decide who inherits your property.
Can I have more than one agent?
Yes. You can name two or more agents and decide whether they must act together or can act separately. If they must act together, both must sign every document. If they can act separately, either one can act alone. Acting separately is simpler but gives each agent more individual power.
What if my agent becomes unable or unwilling to act?
You can name a backup agent (called a successor agent) in the document. If your first agent dies, becomes incapacitated, or refuses the role, the successor agent takes over automatically. If you did not name a successor and your agent cannot act, the power of attorney ends and you or your family may need to go to court.
