How to actually use a power of attorney once you have one
Using a power of attorney means giving the document to the person you named (called the agent or attorney-in-fact) and telling them what decisions you want them to make on your behalf. The agent then uses that document to act in your name — signing contracts, accessing bank accounts, selling property, or making medical decisions, depending on what powers you granted. You do not file it with a court or government office unless a specific transaction requires it. The agent straightforward shows the document to banks, hospitals, real estate offices, or other organisations when they need to prove they have the authority to act.
The power of attorney document itself is the proof of authority. Your agent does not need permission from you each time they use it, and they do not need to register it anywhere. Once you hand it over, your agent can present it to any organisation and say, "I have authority to act on this person's behalf." That organisation then decides whether to accept it based on what powers it grants and whether it appears valid.
Key Takeaways
- Your agent uses the power of attorney document itself as proof of authority — they show it to banks, hospitals, or other organisations when they need to act on your behalf.
- You should give the original signed document or certified copies directly to your agent and keep a copy for your own records.
- Some organisations may ask for additional proof, such as a certified copy, a notarised statement, or confirmation that the document is still valid.
- Your agent's authority begins when ready if you created a general power of attorney, or only when you become incapacitated if you created a durable or springing power of attorney.
- You can revoke the power of attorney at any time by signing a written revocation and notifying your agent and any organisations that have a copy.
Giving the document to your agent and other parties
Start by providing your agent with the original signed power of attorney document or certified copies. A certified copy is a photocopy that a notary public or court clerk has stamped and signed to confirm it matches the original. Many organisations will accept certified copies instead of the original, which protects your original document from wear and loss.
You should also give copies to any organisation your agent may need to deal with on your behalf — your bank, investment firm, insurance company, healthcare provider, or real estate agent. Some organisations keep copies on file so they recognise the document when your agent arrives. Others will only accept the document when your agent actually needs to use it. Either way, having copies in advance can speed things up later.
Keep a copy for yourself and store the original in a safe place — a home safe, safe deposit box, or with your attorney. Tell your agent where you have stored the original so they can retrieve it if needed. This prevents the document from being lost or damaged while still keeping it accessible.
What happens when your agent needs to use it
When your agent needs to act on your behalf, they bring the power of attorney document to the organisation involved. For example, if your agent needs to withdraw money from your bank account, they go to the bank with the document. If they need to sign a contract to sell your house, they bring it to the real estate closing. If they need to make a medical decision, they bring it to the hospital or doctor's office.
The organisation will review the document to confirm that it grants the specific power your agent needs. A bank will check that it authorises financial decisions. A hospital will check that it authorises healthcare decisions. If the document grants that power and is still valid, the organisation will allow your agent to proceed. The organisation may ask your agent to sign forms or provide identification, but the power of attorney itself is the key piece of proof.
Some organisations have their own power of attorney forms and may ask your agent to fill one out instead of using yours. This is common with banks and investment firms. Your agent can ask whether the organisation will accept your document or requires their own form before making the trip. Getting this answer in advance saves time and frustration.
When organisations ask for more than the document
Some banks, hospitals, and government offices will ask for additional proof beyond the power of attorney itself. They may request a certified copy rather than a photocopy, a notarised statement confirming the document is still valid, or proof that you have not revoked it. These requests are legal and common, especially for large financial transactions or medical decisions.
If an organisation asks for something beyond the document, ask them what they need in writing. You or your agent can then work with a notary public or attorney to provide it. Some organisations have specific forms they use for this confirmation. Getting the requirement in writing prevents back-and-forth trips and delays.
A few organisations may refuse to accept your power of attorney even if it is valid. This is rare but can happen if the organisation has its own strict rules or if your document is very old. If this occurs, you may need to consult an attorney about your options, which could include updating the document or pursuing a court order.
Understanding when your agent's authority starts and stops
The timing of your agent's authority depends on the type of power of attorney you created. A general power of attorney gives your agent authority when ready, as soon as you sign it. Your agent can use it right away to act on your behalf. A durable power of attorney also gives authority when ready, but it remains valid even if you become incapacitated — which is why most people use this type. A springing power of attorney does not give authority until a specific event occurs, usually when you become mentally incapacitated. Your document should clearly state which type it is.
Your agent's authority ends when you revoke the document, when you die, or when the document itself states it expires. Some power of attorney documents include an expiration date — for example, "this power of attorney expires on January 1, 2030." If yours has an expiration date and that date passes, your agent no longer has authority. Check your document to see whether it has an expiration date and, if so, when it occurs.
Revoking the power of attorney if you change your mind
You can revoke (cancel) a power of attorney at any time, as long as you are mentally capable of understanding what you are doing. To revoke it, sign a written revocation document that clearly states you are cancelling the power of attorney. Have it notarised if possible, though notarisation is not always required. Give the original revocation to your agent and send copies to any organisation that has a copy of the power of attorney — your bank, doctor's office, or attorney.
Your agent's authority stops as soon as they receive the revocation. Organisations may take a few days to update their records, so follow up with written confirmation if your agent tries to act after you have revoked the document. Keep a copy of the revocation for your records and store it in the same place as the original power of attorney document.
What your agent should and should not do
Your agent has a legal duty to act in your best interest and to follow the powers you granted. They cannot use the power of attorney to benefit themselves unless you explicitly allowed it in the document. For example, if you granted your agent authority over your bank account, they cannot transfer money to their own account unless the document specifically permits it. They also cannot use the power of attorney after you revoke it, after you die, or for any purpose outside the powers you granted.
Your agent should keep records of everything they do on your behalf — money they spend, accounts they access, decisions they make. If you later question what they did, these records prove they acted properly. If you suspect your agent has misused the power of attorney, you can revoke it when ready and consult an attorney about recovering any money or property they took improperly.
Frequently Asked Questions
Do I have to file the power of attorney with a court or government office?
No. A power of attorney is not filed with any court or government office unless a specific transaction requires it. Your agent straightforward shows the document to the organisation they are dealing with. Some states require recording a power of attorney with the county recorder's office if it involves real estate, so check your state's rules if your agent will be selling or mortgaging property.
Can my agent use the power of attorney after I die?
No. 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 after your death, that is handled through your will or trust, not through the power of attorney. Your executor or trustee takes over those duties.
What if my agent loses the power of attorney document?
Your agent can use a certified copy instead of the original. If you no longer have any copies, you can create a new power of attorney document with the same terms and have it notarised. Give the new document to your agent and notify any organisations that have the old one. You can also ask your attorney or the notary who created the original to provide a certified copy from their records.
Can I limit what my agent can do with the power of attorney?
Yes. The power of attorney document itself lists the specific powers you grant. You can limit your agent to certain accounts, certain types of decisions, or certain time periods. For example, you can grant authority over your checking account but not your investment account, or authority to make healthcare decisions but not financial decisions. The more specific you are, the clearer it is what your agent can and cannot do.
What happens if an organisation refuses to accept the power of attorney?
Ask them in writing what they need to accept it. They may want a certified copy, a notarised statement that the document is still valid, or their own form. If they continue to refuse a valid document, consult an attorney about your options. In some cases, you may be able to pursue a court order forcing them to accept it, though this is rare.
