What you need to do to add an account holder
Adding someone to your bank account means giving them legal ownership and access to the money in it. You and the person you're adding both become responsible for the account, and both can withdraw funds, write checks, or close it without the other's permission. The process takes 15 minutes to an hour in person, or a few days by mail or phone, depending on your bank.
Start by contacting your bank directly — call the number on your card, visit a branch, or log into your online banking portal. Tell them you want to add an authorized user or joint owner. These are two different things, and your bank will ask which one you mean. Most banks can walk you through it on the phone or in person the same day.
You'll need the other person present (or their information if doing it by mail), a valid government ID for both of you, and sometimes a Social Security number. The bank will run a background check, usually ChexSystems, which takes a few minutes. If that clears, you're done — the new account holder's name goes on the account and they can access it immediately or within one business day.
Key Takeaways
- Adding someone to your account gives them full legal access to all the money in it, so choose carefully and understand you cannot undo this unilaterally.
- Joint owner and authorized user are different — a joint owner has equal rights and can close the account, while an authorized user can spend money but cannot remove the original owner.
- You need both people present with ID, or you can mail documents to the bank, but in-person or phone is faster.
- The bank will check ChexSystems (a banking history database) on the new person, which takes minutes and usually clears the same day.
- Once added, the new person can access the account immediately or within one business day depending on the bank.
Joint owner versus authorized user — which one to choose
A joint owner has equal rights to the account. They can withdraw money, write checks, add or remove other people, close the account, and change the terms — all without asking you. If the joint owner dies, the account usually passes to you automatically (depending on state law). If you die, it passes to them. This is the right choice if you want someone to have complete control alongside you, like a spouse managing household finances or an adult child managing an aging parent's bills.
An authorized user can spend money and access the account, but cannot close it, change terms, or remove the original owner. They cannot add other people to the account. If you die, the account does not automatically go to them — it goes through your estate. This is the right choice if you want someone to be able to pay bills or make purchases on your behalf, but you want to keep final control. Parents often add teenagers as authorized users on checking accounts.
Ask your bank which option they offer — not all banks support both. Some banks call these by different names: "co-owner," "account owner," "signer," or "secondary cardholder." The rights are what matter, not the label. If your bank only offers one option, ask what rights come with it before you proceed.
How to add someone in person at a branch
Bring the other person and both of your government-issued IDs to any branch of your bank. Tell the teller or banker you want to add them to your account. They will pull up your account, ask which type of access you want (joint owner or authorized user), and have both of you sign paperwork. This usually takes 15 to 30 minutes.
The bank will run a ChexSystems check on the new person while you wait. ChexSystems is a database that banks use to check for fraud, unpaid overdrafts, or closed accounts due to misuse. Most people clear it instantly. If there's a problem, the bank will tell you on the spot and may decline to add them, or may require additional steps.
Once you sign, the new person's name goes on the account. They can use a debit card, write checks, or access online banking immediately, or it may take until the next business day depending on the bank. Ask the banker when they can expect access and whether they need to set up online banking separately.
Adding someone by phone or mail
If the other person cannot come to a branch, most banks will mail you forms to sign. Call your bank and ask them to send an "account modification form" or "authorized user form." You'll fill it out, have both people sign it, and mail it back with copies of both IDs and sometimes a Social Security number.
This takes longer — usually five to ten business days from the time the bank receives the signed forms back. The bank will still run a ChexSystems check, which happens after they receive your paperwork. If something flags, they'll call you to ask questions before proceeding.
Some banks also let you add someone through their mobile app or online banking portal. Log in, look for account settings or "manage account holders," and follow the prompts. You may still need to mail in ID copies or have the other person verify their identity separately. Ask your bank whether this option is available and what documents they need.
What happens after someone is added
The new account holder can access the account through online banking, mobile app, or ATM using a debit card (if the bank issues one). They can see the full transaction history, current balance, and any linked accounts. If you set up bill pay, they can see and modify those payments too.
Both of you are now responsible for the account. If the account goes negative, both of you are liable for overdraft fees. If there's fraud, both of you can report it, but the bank may investigate more slowly if both owners dispute the same transaction. If one person wants to remove the other, they can usually do it online or by calling the bank — the other person does not have to agree.
Some banks send a new debit card to the new account holder automatically. Others require them to request one. Ask the banker whether a card is being mailed and when it will arrive. The new person can usually start using the account before the card shows up if they have online access.
Removing someone from an account later
If you need to remove someone, call your bank or visit a branch. You can usually do this alone — the other person does not have to agree or be present. The bank will ask you to confirm your identity and may have you sign a form. This takes a few minutes to a few days depending on whether you do it in person or by phone.
Once someone is removed, they lose access to the account immediately. Any debit cards in their name stop working. Online banking access is shut off. They cannot see the balance or transaction history anymore. The account stays open and in your name only.
If the person you're removing is a joint owner (not just an authorized user), some banks require both people to agree to the removal, or require you to close the account and open a new one. Ask your bank about their policy before you add someone as a joint owner if you think you might want to remove them later.
What to do if something goes wrong
If the bank denies adding someone because of a ChexSystems issue, ask for the specific reason. The person can dispute inaccurate information directly with ChexSystems by visiting their website or calling 1-800-428-9623. Disputes usually take 30 days to resolve. Once corrected, the bank may agree to add them.
If someone is added but cannot access the account online, call the bank's customer service line. They may need to reset the person's online banking password or resend a verification email. This usually takes a few minutes on the phone.
If you suspect fraud or unauthorized access after adding someone, contact your bank immediately. Report any transactions you did not authorize. The bank will investigate and may freeze the account while they do. Do not wait — banks have time limits on fraud claims, usually 60 days from when you see the unauthorized transaction on your statement.
Frequently Asked Questions
Can I add someone to my account without them knowing?
No. Most banks require both people to be present with ID, or require the other person to sign paperwork and verify their identity. Some banks may allow you to mail in forms, but they will still contact the other person to confirm they agreed. Adding someone without their knowledge is fraud.
What if the person I want to add has bad credit?
Bad credit does not stop someone from being added to a bank account. Banks check ChexSystems (banking history), not credit bureaus. However, if the person has unpaid overdrafts, fraud flags, or closed accounts due to misuse, the bank may decline to add them. Ask the bank what the specific issue is.
Can I add someone to just part of my account balance?
No. When you add someone to an account, they have access to the entire balance and all transactions. You cannot restrict them to a certain amount or certain types of transactions. If you want to limit their access, consider opening a separate account in their name and transferring money to it instead.
What if I want to remove someone but they refuse?
If they are an authorized user, you can remove them without their permission — just call the bank or visit a branch. If they are a joint owner, your bank's policy varies. Some require both people to agree; others let you remove them unilaterally. Call your bank and ask. If removal is not possible, you may have to close the account and open a new one.
Does adding someone to my account affect their credit score?
No. Adding someone as an account holder does not show up on their credit report or affect their credit score. However, if the account goes into overdraft or is reported to collections, it could affect their credit if they are a joint owner and the bank pursues them for the debt.
