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—but only for the specific powers you write into it. The person you name (called the agent or attorney-in-fact) can only do what the document says they can do. If you don't give them the power to sell your house, they cannot sell it, no matter what they ask you. If you don't mention bank accounts, they cannot touch them.

The powers you can grant fall into a few broad categories: financial decisions (paying bills, managing bank accounts, selling property), healthcare decisions (choosing doctors, consenting to treatment), and legal matters (signing documents, handling lawsuits). You decide which of these—and how much of each—your agent gets. You can make the document very narrow (your agent can only access one specific bank account) or very broad (your agent can do almost anything you could do yourself).

The key thing to understand is that you are in control of what goes in the document before you sign it. Once you sign, your agent has only the powers you gave them. If you later want to take a power away, you have to revoke or amend the document in writing.

Key Takeaways

  • A power of attorney only grants the specific powers you write into the document—your agent cannot do anything beyond what you authorize.
  • You can give financial powers (managing money and property), healthcare powers (making medical decisions), or both, depending on what you need.
  • The document takes effect either when ready (a durable power of attorney) or only if you become unable to make decisions yourself (a springing power of attorney).
  • You can name one agent or multiple agents, and you can require them to act together or allow them to act separately.
  • 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, your agent can manage money and property on your behalf. This typically includes accessing bank accounts, paying bills, depositing checks, transferring funds between accounts, and managing investments. Your agent can also buy, sell, or refinance real estate if you give them that power. They can file tax returns, handle insurance claims, and manage retirement accounts.

The scope depends on what you write. You might say "my agent can access my checking account at First National Bank only" or "my agent can manage all my financial accounts and property." You can also set limits—for example, your agent might be allowed to spend up to $5,000 per month but not more, or they might be forbidden from gifting your money to themselves or their relatives.

One important limit: your agent cannot change your will or create a new will, even if you give them broad financial powers. That requires a separate document (a healthcare proxy or living will for medical decisions, or a new will for property after death). Your agent also cannot use your money for their own benefit unless you specifically allow it in writing.

Healthcare Powers and Medical Decisions

A healthcare power of attorney (sometimes called a healthcare proxy or medical power of attorney) lets your agent make medical decisions if you cannot. This includes choosing doctors, consenting to surgery or treatment, deciding whether to continue life support, and accessing your medical records. Your agent can also decide where you receive care—at home, in a hospital, or in a nursing facility.

Healthcare powers are separate from financial powers. You might give someone financial authority to pay your bills but not the power to make medical decisions, or vice versa. Many people name a family member for healthcare decisions and a different person (like an accountant or trusted friend) for financial matters.

Your agent's job is to make the decisions you would make if you could. If you have strong beliefs about certain treatments—for example, you do not want life support—you can write those into the document so your agent knows what to do. Without those instructions, your agent must choose based on what they think is in your best interest.

When the Power of Attorney Takes Effect

A durable power of attorney takes effect as soon as you sign it and stays in effect even if you become unable to make decisions. This is useful if you want your agent to help you manage finances right away—for example, because you are traveling, ill, or straightforward overwhelmed with paperwork. It also protects you if you later develop dementia or another condition that affects your judgment.

A springing power of attorney takes effect only when a specific event happens, usually when a doctor says you are no longer able to make decisions for yourself. The advantage is that your agent has no power until that moment arrives. The disadvantage is that it can be hard to prove you have lost capacity, and your agent may not be able to act quickly when they need to.

Most people choose a durable power of attorney because it is simpler and works when ready. If you are worried about your agent having too much power too soon, you can limit what they can do (for example, they can only access one account) rather than using a springing document.

Naming One Agent or Multiple Agents

You can name one person as your agent, or you can name two or more. If you name multiple agents, you decide whether they must act together (both must agree on every decision) or whether they can act separately (each can make decisions on their own). Acting together is safer because it requires agreement, but it is slower and can create deadlock if the agents disagree. Acting separately is faster but gives each agent more individual power.

You can also name alternate agents—people who step in if your first choice cannot or will not serve. For example, you might name your spouse as your primary agent and your adult child as the alternate in case your spouse dies or becomes unable to help.

Some people name co-agents for specific tasks. You might say "Agent A manages my bank accounts, Agent B manages my real estate, and both must agree on any sale of property." This splits responsibility and adds a layer of oversight.

What Your Agent Cannot Do

Even with broad powers, your agent has limits. They cannot change your will or create a new will. They cannot make decisions about your funeral or burial unless you specifically give them that power. They cannot vote on your behalf in elections (voting rights are personal and cannot be delegated). They cannot change the power of attorney document itself or revoke it—only you can do that.

Your agent also cannot use your money or property for their own benefit unless you explicitly allow it in the document. If they do, you (or your heirs after you die) can sue them to recover the money. This is called a breach of fiduciary duty, and it is taken seriously by courts.

In some states, your agent cannot make gifts of your money to themselves or their relatives unless the document specifically says they can. Even then, the gifts must be reasonable and in line with your past giving habits—an agent cannot suddenly gift away half your estate to themselves.

How Your Agent Must Act

Your agent has a legal duty called a fiduciary duty. This means they must act in your best interest, not their own. They must keep records of what they do with your money and property. They must not mix your money with their own. If you ask them to account for their actions, they must provide receipts, bank statements, and documentation of any decisions they made.

Your agent must also follow any instructions you wrote into the power of attorney document. If you said "my agent can only spend up to $500 per month on my care," they cannot spend $1,000 no matter how good the reason seems. If you said "my agent cannot gift my money to themselves," they cannot do it.

If your agent violates these duties—for example, they steal from you or ignore your written instructions—you can revoke the power of attorney and sue them. After you die, your heirs can also sue an agent who misused your money or property.

Revoking or Changing Your Power of Attorney

You can revoke (cancel) a power of attorney at any time as long as you are mentally able to understand what you are doing. You do this by signing a written revocation document and giving copies to your agent and anyone else who has a copy of the original power of attorney (like your bank or doctor). straightforward telling your agent verbally that you are revoking it is not enough—you need a written document.

You can also amend (change) a power of attorney instead of revoking it entirely. For example, you might want to add a new power, remove a power you no longer need, or change who your agent is. An amendment is a separate document that modifies the original power of attorney.

If you want to make major changes, it is often simpler to revoke the old document and create a new one. This avoids confusion about which powers are in effect and which are not.

Frequently Asked Questions

Can my agent make decisions about my funeral or burial?

Only if you give them that power in the document. Funeral and burial decisions are not automatically included in a financial or healthcare power of attorney. If you want your agent to handle these matters, you must specifically say so in writing.

What happens to the power of attorney when I die?

The power of attorney ends when ready when you die. Your agent no longer has any authority. At that point, your will (if you have one) takes over, and your executor or heirs handle your property and affairs. Your agent must return any original documents and account for any money or property they were managing.

Can I give my agent power over my social media accounts or digital assets?

Some states now allow this, but it is not automatic. You must specifically mention digital assets, email accounts, or social media in the power of attorney document. Laws vary by state, so check your state's rules or ask an attorney if you want to include these.

Does my agent have to tell me what they are doing with my money?

Yes. Your agent must keep records and provide them to you if you ask. They cannot hide their actions or refuse to account for how they spent your money. If they refuse, you can revoke the power of attorney and take legal action.

What if my agent and I disagree about a decision?

If you are still able to make decisions, your wishes come first. You can override your agent's decision or revoke the power of attorney entirely. If you are unable to make decisions and your agent is acting against your known wishes, you or your family can ask a court to step in and remove your agent.
