An authorized signer is someone the account owner gives permission to conduct transactions on their behalf
An authorized signer is a person you name on your bank account who can withdraw money, deposit checks, pay bills, and move funds—but does not own the account. The account owner remains legally responsible for all activity, even transactions the authorized signer makes. Banks require the account owner to sign authorization paperwork that names the signer and specifies what they can do.
Authorized signers are different from joint account holders. A joint owner has equal legal claim to the money and can close the account or remove the other owner. An authorized signer has only the powers you give them and cannot change account ownership or remove themselves without your permission.
The account owner can revoke authorization at any time by notifying the bank in writing. Once revoked, the signer loses access immediately—they cannot make new transactions, though the bank may take a day or two to process the change across all channels (online, mobile, ATM, in-branch).

What an authorized signer can actually do
An authorized signer can perform most routine account transactions. This includes withdrawing cash at the teller or ATM, depositing checks or cash, writing checks (if the account has checkbook access), transferring money between accounts, paying bills online, and receiving account statements. The specific powers depend on what you authorize when you set up the arrangement.
You can limit what a signer can do. For example, you might allow them to deposit and withdraw but not transfer money out of the account, or you might set a daily withdrawal limit. Some banks offer tiered authorization levels—one signer might be able to withdraw up to $500 per day, another up to $5,000. Ask your bank what restrictions are available before you add the signer.
An authorized signer can see the full account history and balance. They receive statements and can view transactions online or by phone. They can also speak with bank staff about the account on your behalf, though some banks require a separate power of attorney document if you want the signer to make major decisions like disputing a transaction or reporting fraud.
What an authorized signer cannot do
An authorized signer cannot change the account owner or add or remove other signers. They cannot close the account, change the account type, modify interest rates or fees, or alter the account's legal structure. If you want to make the signer a joint owner instead, you must do that yourself by visiting the bank and signing new paperwork.
An authorized signer cannot remove themselves from the account. Only the account owner can revoke their authorization. This protects you if a signer becomes unreliable or if you suspect fraud—the signer cannot unilaterally cut off your oversight.
An authorized signer typically cannot act as a power of attorney or make medical or legal decisions on your behalf. Authorization to access a bank account is limited to that account. If you need someone to handle broader financial or legal matters, you must create a separate power of attorney document.
How to add an authorized signer
Visit your bank in person with the person you want to authorize and bring identification for both of you. The bank will ask you to complete an authorization form that names the signer and describes their powers. You will sign the form; the signer may or may not need to sign, depending on the bank's policy. Some banks require the signer to be present; others allow you to add a signer without them there, though they may send the signer a notice afterward.
The process usually takes 10 to 15 minutes. The bank verifies your identity and confirms the account is in good standing. Once you sign, the authorization takes effect immediately for in-person and phone transactions, but online and mobile access may take one to two business days to activate. ATM access typically activates within 24 hours.
You can also add an authorized signer by mail or phone at some banks, though this is less common. Call your bank's customer service line to ask whether they offer remote authorization and what documents they require. You will likely need to mail a signed form and copies of identification.
How to remove an authorized signer
Contact your bank and request removal of the authorized signer. You can do this in person, by phone, or by mail. In-person removal is fastest—bring your ID and ask to speak with an account representative. By phone, you will need to verify your identity by answering security questions or providing your Social Security number. By mail, send a signed letter stating the signer's name and your account number.
Removal takes effect within one to two business days. During that window, the signer may still have access through channels the bank has not yet updated—for example, they might still be able to use an ATM card while online access has already been shut off. Call the bank to confirm the signer no longer has access before you assume the change is complete.
If you suspect the signer has committed fraud or is using the account without permission, notify the bank immediately and ask them to freeze the account pending investigation. Do not wait for the standard removal timeline. The bank can block access within hours if you report suspected fraud.
Authorized signers and liability
You are responsible for all transactions an authorized signer makes, even if they exceed the limits you set or use the account in a way you did not intend. If an authorized signer withdraws money without permission or uses the account for their own purposes, the bank will not refund the money—you authorized them to access the account, and the bank has no way to know whether each transaction was approved by you.
This is why authorized signers are typically family members, caregivers, or people you trust completely. If you suspect an authorized signer has stolen money or committed fraud, you can report it to the bank and to law enforcement, but recovery depends on whether the signer can be held criminally liable. The bank itself is not liable because you authorized the signer's access.
If an authorized signer dies, their access ends automatically once the bank is notified. You do not need to take action, but you should inform the bank so they can update their records and prevent any remaining cards or checks from being used.
Authorized signers versus joint account owners
A joint account owner has equal legal rights to the money and can withdraw all of it, close the account, or remove the other owner without permission. An authorized signer has only the powers you grant and cannot change the account structure. If you want someone to have full control of the account after you die or become incapacitated, a joint account is the right choice. If you want someone to help manage the account during your lifetime but you want to retain full control, an authorized signer is better.
Joint accounts also have tax and estate implications. Money in a joint account may be subject to gift tax if the account is funded by one owner, and it may pass to the surviving joint owner outside of your will. Authorized signers have no claim to the account after you die—the money goes to your estate. Discuss the difference with your bank and consider consulting a tax professional or attorney if you are unsure which option fits your situation.
Frequently Asked Questions
Can an authorized signer see my account balance and transaction history?
Yes. An authorized signer can view the full account balance, all transactions, and statements. They have the same visibility as you do. If you want to keep certain transactions private, do not add that person as an authorized signer.
What happens if an authorized signer uses the account without my permission?
You remain liable for the transaction. The bank will not reverse it because you authorized the signer's access. Your recourse is to report the signer to law enforcement for theft or fraud and pursue criminal or civil action against them personally.
Can I add an authorized signer online or do I have to go to the bank?
Most banks require you to visit in person or call to add an authorized signer. A few banks offer online authorization, but this is uncommon. Contact your bank to ask what methods they support.
Does an authorized signer need to be a family member?
No. An authorized signer can be anyone you trust—a friend, caregiver, business partner, or attorney. The bank does not restrict who you can authorize, only that you verify their identity and sign the authorization form.
If I add an authorized signer, does it affect my credit score?
No. Adding an authorized signer does not appear on your credit report and does not change your credit score. It is purely an account access arrangement.
