The basic steps to add an account holder

To add someone to your checking account, you visit your bank in person or call their customer service line, provide the new person's legal name and Social Security number, and sign paperwork authorizing the change. The bank then verifies the new account holder's identity, runs a background check (usually ChexSystems), and updates their records. The whole process typically takes one to three business days, though some banks complete it the same day if you're both present in a branch.

The new account holder does not have to be present for you to start the process, but most banks require them to sign documents before they can use the account. Some banks mail the paperwork; others ask both of you to sign in person at a branch. Once everything is signed and verified, both of you receive new debit cards and online access credentials.

The specific steps vary slightly by bank. Wells Fargo, Chase, Bank of America, and most regional banks all follow this general path, but the paperwork and timeline differ. Call your bank's customer service number (on the back of your card) and ask what documents you and the new account holder need to bring or sign.

Key Takeaways

  • You can start the process by phone or in person, but the new account holder usually must sign documents before they can access the account.
  • The bank will ask for the new person's legal name, Social Security number, and date of birth, and will run a background check through ChexSystems.
  • The process takes one to three business days from the time both parties sign, though some banks finish the same day if you visit together.
  • Both account holders receive full access to the account, including the ability to withdraw money, write checks, and see all transactions.
  • You can remove someone from the account later by contacting the bank, though some banks require both parties to agree in writing.

What information and documents you'll need

Bring or have ready the new account holder's full legal name (as it appears on their ID), date of birth, and Social Security number. The bank will also ask for a current government-issued photo ID—a driver's license, passport, or state ID card. If the person is not a U.S. citizen, they may need an ITIN (Individual Taxpayer Identification Number) instead of a Social Security number; ask your bank whether they accept ITINs.

If you're adding someone who is under 18, requirements vary by bank. Some banks allow minors on accounts with a parent or guardian; others set a minimum age of 13 or 16. A few banks do not allow minors as primary account holders at all. Call ahead to confirm your bank's policy before you visit.

You will also need to show your own ID and proof that you own the account—usually just your debit card or a recent statement. If you're doing this by mail, the bank will send you and the new account holder separate signature cards or authorization forms to sign and return.

In-person versus phone or mail: which is fastest

Adding someone in person at a branch is usually fastest. If both of you show up with valid IDs, many banks can complete the paperwork the same day and issue new debit cards within one to two business days. You skip the back-and-forth of mailing documents, and the bank verifies both identities on the spot.

Adding someone by phone takes longer. You call customer service, provide the new person's information, and the bank mails signature cards or authorization forms to both of you. You and the new account holder sign and mail them back separately. This process typically takes five to seven business days total, depending on mail delivery and how quickly both parties return the signed documents.

Some banks offer a hybrid: you start by phone, but the new account holder must visit a branch to sign in person. This usually takes three to five business days. A few banks with strong online platforms let you upload a photo of the new person's ID and sign electronically, which can cut the timeline to two to three business days, but this is not yet standard across all banks.

What happens after someone is added to your account

Once the new account holder is officially added, they have the same rights to the account as you do. They can withdraw money, deposit checks, transfer funds, pay bills online, and see the full transaction history. They can also add or remove other people from the account at most banks—so if you add someone you later distrust, they could theoretically add a third party without your permission.

Both of you will receive separate debit cards in the mail, usually within five to seven business days. The new account holder will also receive login credentials for online and mobile banking. If they already bank with your institution, the account may appear in their existing login; if not, they'll need to set up a new online profile.

Your account statements will now show both names on the account. If you have overdraft protection or a linked savings account, the new account holder can access those too. Direct deposits, automatic bill payments, and standing orders all continue as before—adding someone does not interrupt existing transactions.

Removing someone from the account later

To remove someone from a checking account, contact your bank and request to remove them as an authorized user. If the account has only two people and you remove the other, you become the sole account holder. If there are three or more people, the account continues with the remaining holders.

Most banks allow the account owner (the person who opened it originally) to remove someone unilaterally. However, some banks require written consent from the person being removed, especially if they have been on the account for a long time or if the account is held in both names equally. A few banks require both parties to visit a branch together to remove someone.

Removing someone does not close the account or affect existing transactions. The person being removed loses access to the debit card and online banking, but the account itself stays open. If the person being removed had a direct deposit set up, you'll need to update that separately with their employer or the paying organization.

Special cases: joint accounts, minor children, and power of attorney

Adding someone as a joint account holder is different from adding them as an authorized user. A joint account holder has equal ownership and equal legal responsibility for the account. If the account goes negative, both people are liable. If one person dies, the surviving joint holder typically inherits the account automatically. Most banks treat joint holders the same way—both can withdraw, both can remove the other, both are responsible for overdrafts.

Adding a minor child usually means opening a custodial or teen checking account instead of adding them to your existing account. These accounts have spending limits, parental controls, and restrictions on withdrawals. The child becomes the account holder when they reach 18 or 21, depending on the bank. If you want a child to have access to your account without being a formal holder, some banks offer a limited "authorized user" option with restricted permissions.

If you want someone to manage your account without being a legal owner—for example, an adult child managing finances for an aging parent—you can grant power of attorney instead of adding them to the account. This is a legal document, not a banking product, and it requires a lawyer to set up. It gives the person authority to act on your behalf without their name appearing on the account itself.

What to do if the bank denies the request

Banks can refuse to add someone to an account if the person fails the ChexSystems background check, has a history of fraud or unpaid overdrafts, or does not provide valid identification. If this happens, ask the bank why they denied the request. If it was due to ChexSystems, you can dispute the report directly with ChexSystems (visit chexsystems.com) and ask the bank to reconsider once the error is corrected.

If the person has a legitimate reason for the denial—such as a prior banking issue they've since resolved—some banks will reconsider if you provide documentation of the resolution. Others have strict policies and will not add that person under any circumstances. In that case, your options are to switch to a different bank with more lenient policies or to keep the account in your name only.

If you believe the bank made an error or discriminated against the new account holder, you can file a complaint with the Consumer Financial Protection Bureau (CFPB) at consumerfinance.gov. The CFPB investigates complaints about unfair or deceptive banking practices.

Frequently Asked Questions

Can I add someone to my checking account without them knowing?

No. Most banks require the new account holder to sign documents and verify their identity before they can access the account. Some banks allow you to start the process without them present, but they will not complete it until the person signs and provides ID. If someone adds you to an account without your knowledge or consent, that is fraud, and you should contact the bank and law enforcement immediately.

Does adding someone to my account affect their credit score?

No. Adding someone as an account holder does not appear on their credit report and does not affect their credit score. The bank runs a ChexSystems check (a banking history check), not a credit check. However, if the account goes into overdraft and the bank reports it to ChexSystems, that can affect both account holders' banking records.

What if I want to add someone but keep them from seeing my old transactions?

You cannot. Once someone is added to a checking account, they have access to the full transaction history from the day the account opened. If you want to keep old transactions private, you would need to open a separate account and transfer only current funds to it, then add the new person to the new account only.

Can I add someone to my account if they bank somewhere else?

Yes. The new account holder does not have to bank at your institution. They can have accounts at multiple banks. Once they are added to your account, they can access it through your bank's online platform or mobile app, even if they primarily use a different bank.

How long does it take to remove someone from an account?

Removing someone usually takes one to three business days. You contact the bank, request the removal, and sign authorization. The person being removed loses access to the debit card and online banking immediately, though it may take a day or two for the system to fully process the change. Some banks require the person being removed to sign a form as well, which can extend the timeline to five to seven days.
