What you need to do to add a signer
Adding a signer to your checking account means giving another person legal authority to withdraw money, write checks, and make transactions on that account. The process is straightforward: you contact your bank, provide the person's information, and both of you sign paperwork. Most banks complete this within one business day, though some take up to a week.
The person you're adding must be present at the bank or provide a notarized signature, depending on your bank's rules. Some banks allow you to start the process online or by phone, but they will require in-person verification before the new signer can actually use the account. A few banks let you mail in documents, but this is slower and less common.
You do not need a lawyer or any special permission beyond what the bank requires. The bank's job is to confirm that both people are who they say they are and that both agree to the arrangement.
Key Takeaways
- Contact your bank directly—call the number on your debit card or visit a branch—because each bank has different forms and requirements for adding a signer.
- Both you and the new signer will need to provide a government-issued ID and sign the bank's authorization form, usually in person or by notarized mail.
- The new signer becomes a full owner of the account with the same access you have, including the ability to withdraw all funds or close the account.
- The process typically takes one to seven business days from the time both signatures are collected, though some banks are faster.
- You can remove a signer later by contacting the bank, but the person you're adding should understand this is a permanent legal change until you reverse it.
What information and documents you'll need
Bring or provide a government-issued photo ID for both yourself and the person you're adding. This can be a driver's license, passport, state ID card, or military ID. The bank will not accept expired IDs, so check the expiration date before you go.
You will also need the account number of the checking account you want to add the signer to. If you have your debit card or a recent statement, you have this information. The new signer does not need to have an existing account at your bank—they can be completely new to the institution.
Some banks ask for a second form of identification, such as a Social Security number or a utility bill showing the person's current address. Ask your bank what they require before you visit, because showing up without the right documents wastes a trip.
In-person versus remote options
Most banks require at least one person to appear in a branch. The standard process is that you both go together, show your IDs, and sign the forms in front of a bank employee. This takes about 15 minutes and is the fastest way to complete the change.
Some larger banks—including Chase, Bank of America, and Wells Fargo—allow you to start the process online or by phone if you're already a customer, but they still require the new signer to visit a branch in person or provide a notarized signature by mail. A few regional banks and credit unions may allow both people to sign remotely using a video call with a notary, but this is not standard.
If the new signer lives far away, mailing notarized documents is an option at most banks, but it takes two to three weeks instead of one to seven days. A notary public can witness the signature—you can find one at your bank, a UPS Store, or a local courthouse, usually for $5 to $15.
What happens after you add the signer
Once the bank processes the change, the new signer has full access to the account. They can withdraw money, deposit checks, set up automatic payments, and view the full transaction history. They can also add or remove other signers without your permission, and they can close the account entirely.
The new signer will receive their own debit card, usually within 5 to 10 business days. Some banks mail it to the address on file; others let you pick it up at a branch. Ask the bank where the card will go before you leave.
Both of you will see all transactions on the account. If you use online banking, you can both log in and monitor activity. There is no way to hide transactions from a co-signer or to give them limited access—adding someone as a signer means they have the same rights you do.
Removing a signer later
If you need to remove the signer in the future, contact your bank and ask to remove them from the account. You typically need to visit a branch or call and verify your identity. The bank will remove their access, and they will no longer be able to use the debit card or access the account online.
The person being removed does not have to agree to this change—you can remove them unilaterally because you are the original account holder. However, if there is a dispute over money in the account, removing a signer does not resolve who owns what. That becomes a legal question outside the bank's role.
After removal, the bank may send the former signer a notice confirming they no longer have access. This protects both of you by creating a paper trail.
Common reasons to add a signer
People add signers for different reasons: a spouse or partner for joint finances, an adult child to help manage bills for an aging parent, a business partner for a business account, or a trusted family member to handle finances if you become unable to. Each situation has different risks and benefits.
If you're adding someone to help you manage the account temporarily—for example, while you're traveling or recovering from surgery—be clear about when you plan to remove them. A signer has legal rights to the money, so this should be someone you trust completely.
For aging parents, adding an adult child as a signer is simpler than setting up a power of attorney, but it also gives the child full ownership rights to the money. Some families use a power of attorney instead to keep the parent in control while allowing someone else to act on their behalf. Talk to a lawyer if you're unsure which option fits your situation.
Frequently Asked Questions
Can I add a signer without them being present?
Most banks require the new signer to appear in person with a photo ID. Some banks accept a notarized signature by mail, which takes longer but avoids a branch visit. Call your bank to ask what they allow—do not assume they will accept a remote signature.
What's the difference between a signer and an authorized user?
A signer is a co-owner of the account with full legal rights. An authorized user (available on some accounts) can use the account but does not own it and cannot remove other users or close the account. Not all banks offer authorized user status on checking accounts—ask your bank which option they support.
Can I limit what a signer can do, like set a spending cap?
No. A signer has the same access and authority as you do. If you need to restrict what someone can do with the money, a signer is not the right tool—you would need a power of attorney or a trust with specific limits written in. Talk to a lawyer about those options.
What if I add a signer and they take all the money?
Legally, they have not stolen anything—they are a co-owner with the right to withdraw funds. You would need to pursue this as a civil matter, not a criminal one, unless you can prove fraud or coercion. This is why you should only add someone you trust completely.
How long does it take to add a signer?
If you both visit the branch together, the paperwork takes about 15 minutes. The bank usually activates the change within one business day. If you mail notarized documents, expect two to three weeks. Call your bank to ask their specific timeline.
