Yes, you can open a joint account with your brother, but the bank will require both of you to be present or to complete paperwork together
A joint account with your brother works the same way as any other joint account: you both own it, you both can deposit and withdraw money, and you both are legally responsible for any overdrafts or fees. The bank treats you as co-owners from the moment the account opens. Most banks allow this, though some have restrictions on who can be a co-owner—typically requiring you to be related or to have a legal relationship like marriage or guardianship.
The process itself is straightforward. You and your brother will need to go to the bank together, bring identification, and sign the account agreement. Some banks now allow one person to open the account and add the other remotely, but the person being added still has to verify their identity and consent in writing. The bank will run a background check on both of you through ChexSystems (a banking history database) and may check your credit, though a joint account does not require good credit from either party.
Key Takeaways
- Both you and your brother must provide government-issued ID and proof of address when opening a joint account, whether you visit in person or complete the process remotely.
- Either of you can withdraw all the money or close the account without the other's permission, so a joint account only works if you trust each other completely.
- The bank reports the account to credit bureaus under both names, and overdrafts or unpaid fees on the account can affect both of your credit scores.
- If your brother dies, the account automatically passes to you if it is set up as a joint account with survivorship rights—the default at most banks.
- You can change the account to single ownership later, but both of you must agree and sign the change in writing.
What the bank will ask for when you both show up
Bring a government-issued photo ID for each of you—a driver's license, passport, or state ID card. The bank will also ask for proof of address, which can be a recent utility bill, lease, mortgage statement, or government mail dated within the last 60 days. If you have moved recently and your ID does not match your current address, bring both the old and new proof.
The bank will ask you to choose the type of joint account. Most people choose "joint with survivorship" or "joint tenants with rights of survivorship," which means if one of you dies, the other automatically owns the full balance without going through probate. Some banks call this "payable on death" or "POD." If you want the account to go to your brother's estate instead of to you if he dies, you can ask for "joint tenants in common," but this is rare and you should discuss it with him first.
You will also decide on the account type: checking, savings, or money market. Checking accounts have debit cards and unlimited transactions. Savings accounts have limits on how many times you can withdraw per month (usually six) but often pay slightly higher interest. Ask the bank about monthly fees, minimum balance requirements, and whether either of you gets overdraft protection.
What happens if one of you wants to close the account or withdraw everything
This is the biggest risk of a joint account. Either of you can walk into the bank, withdraw all the money, and close the account without telling the other person. The bank has no obligation to notify your brother if you do this. There is no legal requirement that you split decisions or get permission from each other.
If you and your brother have a falling out, he can take the money. If he has creditors, they can pursue the account to pay his debts. If he is sued, the account can be frozen or garnished. You have no legal protection just because your name is on the account—you are equally liable and equally vulnerable.
For this reason, a joint account only makes sense if you trust your brother completely and you have discussed what the account is for. If you are trying to manage money for him because he cannot manage it himself, or if you are trying to protect money from his creditors, a joint account is the wrong tool. A power of attorney or a trust would be better, but those require a lawyer.
How the account affects credit and taxes
The bank reports the account to credit bureaus under both names. If the account goes into overdraft or is sent to collections, it shows up on both of your credit reports. This can lower both of your credit scores, even if only one of you caused the problem. When you apply for a loan or credit card, the lender will see this account and may ask about it.
For taxes, the bank will send a 1099-INT form to both of you if the account earns interest over $10. You and your brother will each report your share of the interest on your tax return. If you have not agreed on how to split the interest, this can cause confusion at tax time. The IRS does not care how you split it—you just both have to report something that adds up to the total.
If your brother receives government benefits like Supplemental Security Income (SSI) or Medicaid, a joint account may affect his benefits. The government may count the entire account balance as his asset, even if you put most of the money in. Before opening a joint account with a brother who receives means-tested benefits, talk to his benefits caseworker or a benefits planning specialist.
What to do if you want to add your brother to an existing account
If you already have a bank account and want to add your brother as a co-owner, you can do this at the bank. You will both need to go in together or complete a form together. The bank will ask for his ID and proof of address. Some banks charge a small fee to add a co-owner; others do not.
When you add him, the account type changes. It becomes a true joint account, which means he can withdraw money and close it just as if he had opened it with you. If you only want him to have limited access—for example, to deposit money but not withdraw it—you cannot do that with a joint account. You would need to set up a power of attorney or add him as an authorized user instead, though not all banks offer authorized user accounts for checking.
Alternatives if a joint account is not the right fit
If you want your brother to have access to money but you do not want him to be able to close the account or withdraw everything, ask the bank about a power of attorney. With a power of attorney, you stay the owner and he acts on your behalf. He can deposit and withdraw, but you can revoke his access anytime. This requires a legal document, usually prepared by a lawyer, but it gives you more control.
If you want to leave money to your brother after you die but you do not want him to have access now, use a payable-on-death (POD) designation on your savings account. You stay the sole owner, but when you die, the money goes directly to him without probate. This is free at most banks and requires only a form.
If you are trying to save money together for a shared goal—a vacation, a car, a house down payment—a joint account works fine as long as you both trust each other and you have agreed on the purpose. But if one of you is worried the other might take the money, a joint account will create conflict, not solve it.
Frequently Asked Questions
Do we both have to be present to open the account?
Not always. Some banks allow one person to open the account and add the other remotely through an app or website. The person being added will need to verify their identity and sign consent electronically. Call your bank to ask if they offer this option. If they do not, you will both need to visit a branch together.
What if my brother has bad credit or a ChexSystems record?
A joint account does not require good credit from either person. The bank will check ChexSystems (a banking history database) for both of you, but a negative record does not automatically disqualify you. Some banks are stricter than others. If one bank turns you down, try another—credit unions and smaller regional banks are often more flexible.
Can I remove my brother from the account later?
Yes, but he has to agree. You cannot unilaterally remove him. You both have to go to the bank and sign a form to change the account back to single ownership. If he refuses or is unreachable, you can close the account and open a new one in your name alone, but he will still have access to the closed account's history.
What happens to the account if my brother gets divorced or sued?
If your brother is sued or owes money to creditors, they can pursue the joint account to collect. A creditor can freeze the account or garnish it. If he is going through a divorce, his spouse may claim a share of the joint account, depending on your state's laws. For this reason, do not open a joint account with someone who has legal or financial problems pending.
Is a joint account the same as a joint savings goal account?
No. A joint account is a legal ownership structure where both people own the money equally and both can access it fully. Some banks offer "shared savings" or "goal" accounts that are really just regular accounts with a different name. The legal structure is the same—both owners have full access—but the marketing is different. Ask the bank to explain what they mean by their product name.
