A notarized power of attorney has no built-in expiration date unless you write one in

A notarized power of attorney lasts as long as you want it to, unless the document itself sets an end date. Many people assume notarization adds an expiration—it does not. Notarization only confirms that you signed the document in front of a notary public and that you appeared to understand what you were signing. The length of time the power of attorney remains valid depends entirely on what you wrote into it when you created it.

This matters because a power of attorney that never expires—called a durable power of attorney—continues to work even if you become mentally incapacitated. One that expires on a specific date stops working on that date, no matter what. And one that you never formally revoke can technically remain valid for decades, even if you no longer want the person holding it to have that authority.

Key Takeaways

  • Notarization does not set an expiration date; the document itself must state when it ends, if ever.
  • A durable power of attorney with no end date remains valid even if you become unable to make decisions yourself, which is why many people choose this option.
  • A power of attorney that expires on a specific date stops working automatically on that date, and the agent can no longer act on your behalf.
  • You can revoke a power of attorney at any time by signing a written revocation and notarizing it, then giving copies to your agent and anyone who might rely on it.
  • Banks, hospitals, and other institutions may refuse to honor an old power of attorney even if it is still technically valid, so you may need a fresh copy.

Durable versus non-durable: what the difference means for how long it lasts

A durable power of attorney continues to work if you become incapacitated—unable to make decisions due to illness, injury, or cognitive decline. The word "durable" is the key. If your document says it is durable, or if your state's law automatically makes all powers of attorney durable unless stated otherwise, then your agent can keep acting on your behalf even after you lose the ability to do so yourself. This is why most people choose a durable power of attorney: it protects them if something happens to their mind, not just their body.

A non-durable power of attorney ends the moment you become incapacitated. If you sign a non-durable power of attorney and then have a stroke or develop dementia, your agent's authority stops when ready. At that point, someone would need to go to court and ask a judge to appoint a guardian or conservator to handle your affairs—a slower and more expensive process. Non-durable powers of attorney are rare and usually used only for very short-term, specific tasks, like having someone sign a real estate document on your behalf while you are out of the country.

Whether your power of attorney is durable or non-durable, notarization does not change how long it lasts. The notary's job is only to verify your identity and confirm you signed willingly. The notary does not check whether the document says "durable" or set any timeline.

When you set an expiration date in the document itself

You can write a specific end date directly into your power of attorney. For example, you might create a power of attorney that expires on December 31, 2027, or one that lasts for exactly two years from the date you sign it. Once that date arrives, the document is no longer valid, and your agent has no authority to act on your behalf anymore.

People often choose an expiration date when they want the power of attorney to cover a specific project or time period. You might give someone power of attorney to manage a business deal that you expect to close within six months, or to handle your affairs while you are traveling for a year. Once the important date passes, the agent's authority ends automatically—you do not have to do anything else to stop it.

The problem with an expiration date is that you may forget it is coming, or circumstances may change and you may need the power of attorney to last longer. If the date passes and you still need your agent to act on your behalf, you will have to create a new power of attorney and have it notarized again. Some people avoid this by creating a durable power of attorney with no expiration date, then revoking it later if they no longer need it.

Powers of attorney with no expiration date and no revocation

If your power of attorney has no end date written into it and you never formally revoke it, the document remains valid indefinitely—even after you die. This can create problems. Your agent might still have the authority to act on your behalf years later, even though you no longer want them to. After you die, your executor or heirs may discover that your old agent is still trying to access your accounts or sign documents in your name.

For this reason, it is important to revoke a power of attorney in writing once you no longer need it. A written revocation should state clearly that you are canceling the power of attorney, and it should be notarized just like the original document. You should give copies of the revocation to your agent, your bank, your doctor's office, and anyone else who might rely on the power of attorney. Without a formal revocation, institutions may still honor the old document if your agent presents it.

Some states allow you to revoke a power of attorney straightforward by destroying the original document or telling your agent it is no longer valid, but notarizing a written revocation is the safest approach. It creates a clear record that you ended the agent's authority on a specific date.

Why institutions may refuse an old power of attorney even if it is still valid

Banks, hospitals, and government agencies often refuse to honor a power of attorney if it is more than a few years old, even if the document has no expiration date and you never revoked it. They do this because they want to be certain the document is still what you want, and because old signatures can be hard to verify. A power of attorney from 2010 may technically still be valid, but your bank may ask you to create a new one dated within the last year or two.

This is especially common with healthcare powers of attorney. Hospitals frequently ask for a fresh copy, sometimes dated within the past six months or a year. They want to be confident that you still want the person named in the document to make medical decisions for you, and that you have not changed your mind in the years since you signed it.

If an institution refuses your power of attorney because it is old, you have two options: create a new one and have it notarized, or ask the institution what specific concerns they have and whether they will accept the old one if you sign a statement confirming it is still valid. Some places will accept a notarized statement from you saying the power of attorney is still in effect, which is faster than creating a brand-new document.

How to check if your power of attorney is still valid

To know whether your power of attorney is still valid, look at the document itself and answer three questions. First, does it have an expiration date written in it? If yes, check whether that date has passed. Second, have you revoked it in writing? If you signed a written revocation and notarized it, the power of attorney is no longer valid. Third, is the document so old that institutions are likely to refuse it? If it is more than a few years old and you have not used it recently, you may want to create a new one even if the old one is technically still valid.

If you are unsure whether your power of attorney is still valid, or if you want to know what it says, find the original document and read it carefully. Look for language about when it expires, whether it is durable, and what authority you gave to your agent. If you cannot find the original, you may have a copy in your files, with your lawyer, or with your agent. If you still cannot locate it, you can create a new power of attorney and have it notarized—this is often simpler than trying to track down an old document.

Revoking a power of attorney you no longer need

To revoke a power of attorney, write a clear statement saying you are canceling it, sign it in front of a notary public, and give copies to your agent and to any institution that might rely on the document. The revocation does not have to be long or formal. A straightforward statement like "I hereby revoke the power of attorney I signed on [date]" is enough, as long as you sign it and have it notarized.

After you revoke the power of attorney, your agent has no authority to act on your behalf anymore. However, institutions may not know about the revocation unless you tell them. If your agent presents the old power of attorney to your bank or doctor's office, they may not realize it has been revoked. For this reason, send copies of the revocation to your bank, insurance company, healthcare providers, and anyone else who has a copy of the original power of attorney. Keep a copy for your own records.

If your agent refuses to stop acting on your behalf after you revoke the power of attorney, or if they misuse the authority you gave them, you may need to contact a lawyer. In some cases, you can report them to law enforcement or file a civil lawsuit to recover money or property they took without your permission.

Frequently Asked Questions

Does notarization expire?

No. Notarization is a one-time verification that you signed the document in front of a notary. It does not expire. However, institutions may refuse to honor an old notarized document if they believe it is too old to be reliable, even though the notarization itself is still valid.

What happens to a power of attorney after I die?

A power of attorney ends when you die. Your agent no longer has any authority to act on your behalf. Your executor or heirs take over managing your estate according to your will or your state's inheritance laws. If your agent tries to use the power of attorney after your death, they may be committing fraud.

Can I change my mind about who I named as my agent?

Yes. You can revoke the power of attorney in writing and create a new one naming a different agent. Both documents should be notarized. Send the revocation to your old agent and to any institution that has a copy of the original power of attorney.

If my power of attorney has no expiration date, will it last forever?

Technically yes, unless you revoke it or die. However, institutions may refuse to honor it if it is very old. Creating a new power of attorney every few years, or whenever you want to update it, is a practical way to may support your agent can still act on your behalf when you need them to.

Can my agent use an old power of attorney if I have not revoked it?

Yes, unless the document has an expiration date that has passed. However, banks and other institutions may refuse to accept it because it is old. Your agent may need to ask you to create a new one, or you may need to sign a statement confirming the old one is still valid.
