A power of attorney expires on the date you set it, or when you die — whichever comes first

A power of attorney is a legal document that gives another person the right to act on your behalf. It does not automatically expire after a set time. Instead, it lasts until one of four things happens: the date you wrote into the document arrives, you revoke it in writing, you become mentally incapacitated (unless it is a durable power of attorney), or you die.

The expiration date is your choice when you create the document. You can set it for six months from now, five years from now, or any other date. If you do not write in an expiration date, the power of attorney remains valid until you revoke it or you die — unless state law sets a default limit, which varies by location.

A durable power of attorney is different. It stays in effect even after you become mentally incapacitated, which is why many people use it for long-term planning. It still expires on the date you set, or when you die, but it does not end if you lose the ability to make decisions yourself.

Key Takeaways

  • You choose the expiration date when you create the power of attorney, or you can leave it open-ended so it lasts until you revoke it or die.
  • A durable power of attorney remains valid even if you become mentally incapacitated, but it still expires on the date you set or when you die.
  • Once a power of attorney expires, the person you named (your agent) loses the legal right to act on your behalf when ready.
  • You can revoke a power of attorney at any time by signing a written revocation and giving it to your agent and any institutions that know about it.
  • State law varies on whether a power of attorney has a default expiration date if you do not write one in.

Why you might set an expiration date

Setting an expiration date gives you control over how long someone else can act on your behalf. If you need help managing finances or medical decisions for a specific period — say, while you recover from surgery or during a business transaction — you can set the power of attorney to end on a particular date.

An expiration date also forces you to revisit the arrangement. When the date approaches, you can decide whether to renew the power of attorney with the same person, change the terms, or end it altogether. This is useful if circumstances change — your agent moves away, your relationship shifts, or you no longer need their help.

Some people create a power of attorney with no expiration date because they want it to remain in effect indefinitely. This is common for durable powers of attorney used for long-term care planning. In this case, the document lasts your entire lifetime unless you revoke it.

What happens when a power of attorney expires

When the expiration date arrives, your agent's authority ends when ready. They can no longer sign documents, access your bank accounts, make medical decisions, or take any other action on your behalf. If they try to act after expiration, they may be acting without legal authority, which could create problems for both of you.

Banks, healthcare providers, and other institutions may not know the power of attorney has expired unless you tell them. If your agent tries to use an expired document, the institution may reject it — or they may not catch the expiration date and accept it anyway. To avoid confusion, notify anyone who has a copy of the power of attorney when it expires.

If you need your agent to continue acting on your behalf after the expiration date, you will need to create a new power of attorney before the old one ends. There is no automatic renewal. You must sign a new document, have it witnessed or notarized (depending on your state's requirements), and give copies to your agent and relevant institutions.

How to revoke a power of attorney before it expires

You can end a power of attorney at any time, even if the expiration date is years away. To revoke it, you must sign a written revocation document. This document should state that you are revoking the power of attorney, name the document you are revoking (including the date you signed it), and state the date the revocation takes effect.

Give the signed revocation to your agent in person or by mail. Also send copies to any bank, healthcare provider, or other institution that has a copy of the original power of attorney. Keep a copy for your records. Some people have the revocation notarized to create a clear record, though this is not always required.

If you lose contact with your agent or they refuse to acknowledge the revocation, you can still revoke the power of attorney by notifying the institutions that use it. Tell them in writing that the power of attorney is no longer valid and ask them to update their records. This does not revoke the document itself, but it prevents your agent from using it with those specific institutions.

Durable versus non-durable powers of attorney and expiration

A non-durable power of attorney ends if you become mentally incapacitated. This is useful for short-term situations where you need someone to handle a specific task while you are able to oversee it. If you later lose the ability to make decisions, the power of attorney automatically ends, and your agent can no longer act on your behalf.

A durable power of attorney continues even after you become mentally incapacitated. This is why it is often used for long-term planning — your agent can keep managing your finances or healthcare decisions even if you develop dementia or another condition that affects your judgment. However, a durable power of attorney still expires on the date you set, or when you die.

Some states use different language. A few states call a durable power of attorney a "springing" power of attorney if it only takes effect after you become incapacitated. Others allow you to create a power of attorney that is durable for healthcare decisions but not for financial decisions. Check your state's laws or speak with an attorney if you are unsure which type you need.

State-by-state differences in expiration rules

Most states do not set a default expiration date for a power of attorney. If you do not write in an expiration date, the document remains valid until you revoke it or die. However, a few states have different rules. Some states set a default expiration date of five or seven years if you do not specify one in the document.

A handful of states require you to renew a power of attorney every few years, even if you want it to last longer. This is less common but does exist in some places. Your state's laws also determine what language you must use to make a power of attorney durable, what witnesses or notarization you need, and whether you can revoke it verbally or only in writing.

Because rules vary, it is worth checking your state's specific requirements or consulting a local attorney before creating a power of attorney. The cost of a brief consultation is usually small compared to the cost of fixing a document that does not work the way you intended.

Frequently Asked Questions

Can I extend a power of attorney after it expires?

No, you cannot extend an expired power of attorney. Once the expiration date passes, the document is no longer valid. You must create a new power of attorney if you want your agent to continue acting on your behalf. You can sign the new document before the old one expires to avoid any gap in authority.

What if I die while a power of attorney is still valid?

A power of attorney ends when ready when you die. Your agent can no longer act on your behalf. If your estate needs to be managed, your will or state law determines who handles that — usually an executor or administrator, not the person who held your power of attorney.

Does a power of attorney expire if I become incapacitated?

Only if it is non-durable. A durable power of attorney stays in effect even after you lose the ability to make decisions. A non-durable power of attorney ends as soon as you become incapacitated. This is why most people use a durable power of attorney for long-term planning.

Can my agent use an expired power of attorney by mistake?

Technically, no — an expired power of attorney has no legal force. However, some institutions may not catch the expiration date and accept it anyway. To prevent problems, notify your bank, healthcare providers, and other relevant institutions when the power of attorney expires. Ask them to update their records and reject any future use of the expired document.

Do I need a lawyer to revoke a power of attorney?

No, you can revoke a power of attorney yourself by signing a written revocation and sending it to your agent and relevant institutions. However, if your agent is uncooperative or you are unsure whether the revocation was received, an attorney can help may support the revocation is properly documented and delivered.
