In almost every state, you cannot open a bank account at 17 without a parent or another adult co-signer. There’s no federal law that stops a minor from having a bank account, but the account itself is a contract, and most states hold that someone under 18 lacks the legal capacity to be fully bound by one. Banks respond by requiring an adult with full contract capacity to share the account. A few narrow exceptions exist, and they’re worth knowing before you assume you’re stuck.
Why Banks Won’t Open an Account for a Minor Alone
When you open a bank account, you’re signing an agreement: the bank holds your money under certain terms, and you agree to the fees, overdraft rules, and other conditions attached. Under the contract law of nearly every state, a person under 18 can “disaffirm” a contract — walk away from it — before turning 18. That leaves the bank with no reliable way to enforce the terms or recover an overdrawn balance.
Federal banking regulators have said plainly that no federal law prohibits minors from opening savings accounts; the restriction lives in state contract law.1U.S. Department of the Treasury. Guidance to Encourage Financial Institutions’ Youth Savings Programs and Address Related Frequently Asked Questions Because the contract with a minor is potentially voidable, most banks will not open an account for a 17-year-old unless an adult signs on too. The adult is the person the bank can hold accountable if things go wrong.
The Narrow Exceptions
A small number of states have passed laws that let a minor enter into an enforceable contract for a deposit account. Washington is one example: a minor there can open a bank account that is just as binding as an adult’s.2Office of the Comptroller of the Currency. Guidance to Encourage Financial Institutions’ Youth Savings Programs and Address Related Frequently Asked Questions Even where state law allows it, individual banks may still require a co-signer as a matter of internal policy. Call the bank before you go in, and ask specifically whether they open accounts for 17-year-olds without a parent.
The other exception is emancipation. If a court has granted you legal adult status, you can generally enter into contracts on your own. Bring a certified copy of the emancipation order to the bank. Front-line staff don’t see these documents often, so it helps to call ahead and ask to work with a branch manager who can review the paperwork.
Outside of those situations, expect to bring an adult. That adult doesn’t have to be a parent — a legal guardian works, and some banks will accept another adult relative — but the bank will want somebody over 18 on the signature card with you.
What to Bring When You Open the Account
Federal anti-money-laundering rules require every bank to run a Customer Identification Program when someone opens an account. At a minimum, the bank must collect four pieces of information from each account holder: full legal name, date of birth, a residential address, and a taxpayer identification number, which for U.S. persons is a Social Security number.3eCFR. 31 CFR 1020.220 – Customer Identification Program Requirements for Banks
In practice, plan to bring:
- A government-issued photo ID such as a driver’s license, learner’s permit, state ID card, or passport. If you don’t have one, some banks will accept a school ID paired with a birth certificate.
- Your Social Security card or another document that shows your full number.
- Proof of your address, which can be a school transcript, report card, or official mail. A utility bill or bank statement in your co-signer’s name showing the same address usually works for both of you.
- An opening deposit, commonly somewhere between $25 and $100 depending on the account.
The adult co-signer needs their own photo ID, Social Security number, and proof of address. Some banks also ask them for employment information or an existing account number.
One thing to know about the application: many banks screen new customers through ChexSystems, which tracks banking history like unpaid overdrafts and accounts closed for cause. You almost certainly have no ChexSystems record yet, but your co-signer’s history will be reviewed, and a bad record on their file can get the application denied. If that happens and ChexSystems was used, you can request the report — but because ChexSystems requires direct requestors to be at least 18, a parent or guardian has to submit the request by mail on your behalf.4ChexSystems.

Joint Account or Custodial Account
Banks generally offer two account structures when a minor is involved, and they work very differently in terms of who controls the money.
Joint Accounts
A joint account gives you and your adult co-signer equal access. Either of you can deposit, withdraw, or spend from it, and both of you share responsibility for any fees or negative balances. For a 17-year-old who wants to deposit a paycheck, carry a debit card, and manage day-to-day spending, this is usually the practical choice. Just keep in mind that your co-signer can see every transaction and can pull money out at any time. If that matters to you, talk about expectations before you sign.
Custodial Accounts
Custodial accounts under the Uniform Transfers to Minors Act or the Uniform Gifts to Minors Act are structured differently. The money legally belongs to you, but a custodian, usually a parent, controls all withdrawals, and those withdrawals must be used for your benefit.5FINRA. 2019 Report on Examination Findings and Observations – UTMA and UGMA Accounts You cannot spend from it directly. That makes a custodial account better suited to long-term savings or gift money than to everyday use.
The age when a custodial account terminates and the funds transfer to you varies by state. It can range from 18 to as late as 25, depending on the type of account and your state’s law, and the default is 21 in most states. On that date, the custodian is required to hand the money over to you.
How to Actually Open It
You can apply in person at a branch or online. A branch visit is often easier for a first-time account because the banker can verify documents on the spot, witness signatures, and answer questions. If you apply online, you’ll go through identity verification and sign the terms electronically, which carries the same legal weight as a handwritten signature under federal law.6Office of the Law Revision Counsel. 15 USC Chapter 96 – Electronic Signatures in Global and National Commerce
Processing typically takes one to two business days. You’ll get your account and routing numbers either immediately (for online applications) or by welcome letter or secure message (for in-branch ones). A physical debit card usually shows up in the mail within seven to ten business days and has to be activated through the app or a phone call before it works.
What Changes When You Turn 18
On your 18th birthday, you gain full contract capacity. You can open an individual account in your own name at any bank, no co-signer required. Your existing account doesn’t automatically change, though, and what happens next depends on the type.
If you have a joint account, you’ll need to contact the bank to either remove your co-signer and convert the account to an individual one, or close it and open a new account in your name. Some banks handle the conversion easily; others require a fresh account. A student or teen account may also convert to a standard adult account with different fee terms, so read the new terms before it happens.
If you have a custodial account, the custodian is required to transfer control to you when you reach your state’s termination age. In many states, that age is 21, not 18, so the custodian may keep authority over the funds for several years after you become a legal adult. Some banks send a notification as the date approaches, but not all do. FINRA has documented cases where custodians continued making withdrawals from custodial accounts well after the beneficiary reached the termination age.5FINRA. 2019 Report on Examination Findings and Observations – UTMA and UGMA Accounts If a custodial account was set up for you, look up your state’s termination age, mark the date, and contact the institution ahead of time to make sure the transfer happens on schedule.
