Yes, you can open a joint account with anyone — marriage is not required
A joint bank account is a legal arrangement between two or more people, and banks do not require you to be married to create one. You can open a joint account with a family member, business partner, friend, or anyone else you trust with shared finances. The bank's concern is not your relationship status but your identity, your ability to fund the account, and whether both account holders consent to the arrangement.
What matters to the bank is that both people show up with valid identification, agree to the account terms, and understand that each person has full access to all the money in the account. Marriage does not change these requirements — it only affects how the account is treated if one person dies or if you separate and need to divide assets.
Key Takeaways
- You can open a joint account with anyone — a parent, adult child, sibling, business partner, or friend — without being married.
- Both account holders must appear in person at the bank with government-issued ID and a Social Security number or tax ID.
- Each person on the account has full access to all the money, regardless of who deposited it, unless you set up restrictions with the bank.
- If you are not married and the account holder dies, the money goes to their estate, not automatically to the surviving account holder — unless the account is set up as "transfer on death" or "payable on death".
- Unmarried couples should discuss what happens to the account if you separate, since the bank will not automatically divide it.
Who can be on a joint account with you
Banks allow joint accounts between any two or more people, regardless of relationship. Common arrangements include parent and adult child, siblings, domestic partners, business co-owners, or friends managing shared expenses. The bank does not verify your relationship — they only confirm that both people are who they say they are and that both consent to the account.
The one restriction is age: most banks require all account holders to be at least 18 years old. A few banks allow a minor to be on a joint account with a parent or guardian, but the adult is usually the primary account holder and the minor's access may be limited. Check with your specific bank about their rules for minors.
What you need to bring to open the account
Both people must appear together at the bank branch. Bring a government-issued photo ID (driver's license, passport, or state ID card) and your Social Security number or Individual Taxpayer Identification Number (ITIN). Some banks also ask for a second form of ID or proof of address, such as a utility bill or lease.
You will also need to decide on the account type — checking, savings, or money market — and agree on the initial deposit amount. Some banks require a minimum opening deposit, which varies by institution and account type. Bring a debit card or checkbook if you want one, though the bank can mail these to you after the account opens.
How access and ownership work on a joint account
On a standard joint account, both people have equal legal rights to all the money. Either person can withdraw, deposit, or transfer funds without permission from the other. This means if you open a joint account with someone, you are trusting them with full access to your money at all times. There is no way to restrict one person's access while keeping the account joint.
If you want one person to have limited access — for example, a parent managing money for an adult child but not allowing withdrawals — you would need a different account structure, such as a power of attorney or a custodial account. Ask your bank what options exist for your specific situation.
What happens to the account if one person dies
This is where marriage and unmarried status differ significantly. If you are married and the account is set up as "joint tenants with rights of survivorship" (the default in most states), the surviving spouse automatically inherits the account. If you are not married, the account does not automatically pass to the other person — it becomes part of the deceased person's estate and goes through probate or is distributed according to their will.
To avoid this, you can ask your bank to set up the account as "transfer on death" (TOD) or "payable on death" (POD). With this structure, you name a beneficiary, and the account passes directly to that person when you die, without going through probate. Not all banks offer this option, and the rules vary by state, so ask your bank whether it is available and what paperwork is needed.
Separating finances if the relationship ends
If you and the other account holder separate or have a falling out, the bank will not automatically divide the account. Both people retain full access and legal rights to all the money unless you close the account or one person removes themselves. This can create conflict if one person withdraws all the funds or if you disagree about who owns what portion.
The safest approach is to discuss this before opening the account: decide whether the money is truly shared, who contributed what, and what happens if you separate. If you cannot agree, consider opening separate accounts and using a third-party payment app for shared expenses instead. If a dispute arises after the account is open, you may need to involve a lawyer or small claims court to divide the funds — the bank will not do this for you.
Tax and fraud considerations
The IRS does not care whether you are married or unmarried; both account holders are responsible for reporting income from the account, such as interest earned. The bank will send a 1099-INT form to both people if interest exceeds a certain threshold. You and the other account holder should agree on how to report this on your tax returns.
If one person deposits money that is not theirs — for example, stolen funds or money from fraud — both account holders can be held liable. Banks also monitor joint accounts for suspicious activity, and either person's behavior can trigger a fraud investigation that affects the entire account. Make sure you trust the other person completely before opening a joint account.
Frequently Asked Questions
Can I open a joint account online without going to the bank in person?
Most banks require both account holders to appear in person with ID to open a joint account. Some online banks may allow you to open the account online and then verify identity in person later, but this varies. Call your bank to ask whether in-person appearance is required or whether they offer an alternative process.
What if the other person does not want to appear in person?
Both people must consent and provide their identity information. If someone refuses to appear or provide their Social Security number, you cannot open a joint account with them. You would need to open a separate account and use other methods to share expenses, such as a payment app or a third-party account designed for shared spending.
Can I remove someone from a joint account without their permission?
No. Both account holders have equal rights, so you cannot unilaterally remove someone. You can close the account entirely, but the bank will typically require both people to sign off. If you want to separate finances, you may need to withdraw your portion and open a new account, or involve a lawyer if there is a dispute.
Will opening a joint account affect my credit score?
Opening a joint account itself does not affect your credit score. However, if the account is overdrawn or goes into collections, it can appear on both account holders' credit reports. Make sure the other person is financially responsible and that you both understand the account terms.
What if I want the other person to have access but not ownership?
A joint account gives both people equal ownership and access. If you want someone to manage money on your behalf without owning it, consider a power of attorney, a custodial account, or adding them as an authorized user on your account (though this still gives them access to all funds). Ask your bank what options are available.
