Yes, but the adult on the account controls it until the minor reaches the bank's age threshold

You can open a checking account for a minor, but the structure depends on the minor's age and the bank's rules. Most banks offer two paths: a custodial account (also called a minor account or youth account) where a parent or guardian is the legal owner and the minor is an authorized user, or a joint account where both names appear on the account and both can withdraw funds. The adult retains full control in either case until the minor reaches a set age—usually 18, sometimes 21—at which point the account converts to a standard individual account or the minor's name can be removed.

The practical difference matters. In a custodial account, the adult can see all transactions and set spending limits through the bank's app or online portal. In a joint account, both parties have equal access and either can drain the account without the other's permission. Most parents choose custodial accounts for younger children (under 13) and joint accounts for teenagers who need more independence but still benefit from parental oversight.

Key Takeaways

  • A custodial account requires one parent or guardian to be the legal owner, with the minor as an authorized user; the adult controls the account until the minor reaches the bank's age threshold.
  • Joint accounts list both the adult and minor as owners, giving both equal access and withdrawal rights from day one.
  • Most banks convert custodial accounts to individual accounts when the minor turns 18, though some require action from the account holder to complete the switch.
  • You will need the minor's Social Security number, proof of identity for both the adult and minor, and proof of address for the adult.
  • Some banks allow online account opening for minors; others require an in-person visit to a branch with both the adult and child present.

What documents you need to bring

The adult will need a government-issued photo ID (driver's license, passport, or state ID) and proof of current address, usually a recent utility bill, lease, or bank statement. The minor needs a Social Security number and proof of identity. For children under 16, this is often a birth certificate, school ID, or state ID card. For teenagers 16 and older, a state ID or learner's permit usually works.

Some banks ask for additional documentation if the minor is not the biological child of the account owner—for example, if a grandparent or legal guardian is opening the account. In those cases, bring custody papers or a court order establishing guardianship. Call the bank's customer service line before you visit to confirm what counts as proof of address and identity at that specific branch, since requirements vary.

Age limits and account conversion

Most banks allow you to open a custodial account for a child of any age, including infants. However, the minor cannot legally own the account until they reach the age of majority in your state, which is 18 in most places. At that point, the account automatically converts to an individual account in the minor's name, or the bank sends a notice asking the now-adult account holder to confirm they want to keep the account open.

Some banks set their own thresholds higher than state law requires. A few institutions convert accounts at 21 instead of 18, or require the young adult to visit a branch in person to complete the conversion. Read the account agreement before opening to see what age triggers the change and what steps you or the minor will need to take. If the account does not convert automatically, the minor may lose access to the account on their 18th birthday until they complete the conversion process themselves.

Spending controls and monitoring tools

Most custodial accounts come with parental controls built into the bank's mobile app. You can set daily spending limits, block certain types of transactions (like online purchases or ATM withdrawals), and receive alerts when the minor uses the card. Some banks let you turn the debit card on and off remotely. These tools vary widely by institution—a large national bank may offer more granular controls than a credit union or online bank.

Joint accounts typically do not include these controls, since both account holders have equal rights. If you want to monitor spending on a joint account, you will need to check the account online or ask the minor to share transaction details with you. Some banks offer transaction alerts to all account holders, so you can see when either person makes a withdrawal or purchase, but you cannot prevent the minor from accessing the funds.

Where to open the account

Most major banks—Chase, Bank of America, Wells Fargo, Citibank—offer custodial checking accounts at any branch. Credit unions often have youth accounts as well, sometimes with lower or no minimum balances. Online banks like Ally, Charles Schwab, and Discover typically do not offer accounts for minors, since they cannot verify identity in person. If you want to open an account online, you will need to use a bank with a physical branch or a bank that partners with a verification service.

Some banks let you open a custodial account entirely online if you have an existing account with them and can verify your identity through their app. Others require both the adult and minor to visit a branch together. A few banks allow the adult to open the account alone and add the minor's information later. Call ahead or check the bank's website to see which process applies to your situation.

Fees and minimum balances

Many banks waive monthly maintenance fees on custodial and youth accounts, especially if the account is linked to a parent's existing account or if direct deposit is set up. However, some institutions charge a small monthly fee ($3 to $5) even on minor accounts. Minimum balance requirements vary—some banks require no minimum, while others ask for $25 to $100 to keep the account open.

Overdraft fees, ATM fees, and out-of-network transaction fees explore to minor accounts the same way they do to adult accounts. If the minor uses an ATM outside the bank's network, you may pay $2 to $3 per transaction. Some banks offer free out-of-network ATM access as part of their account package. Review the fee schedule before opening to understand what costs might explore if the minor makes a mistake or uses the card in an unexpected way.

What happens when the minor turns 18

On the minor's 18th birthday, the account either converts automatically to an individual account in their name, or the bank sends a notice that conversion is required. If it converts automatically, the parent's name is removed from the account and the now-adult account holder has sole control. If conversion requires action, the young adult must visit a branch or complete the process online to finalize the change. Until they do, the account may be frozen or the parent may retain access.

Some banks allow the parent to stay on the account as a joint owner if both parties agree, even after the minor turns 18. This is useful if the young adult wants continued oversight or if they are still living at home. Other banks require the parent's name to be removed at 18. Check the account agreement to understand your bank's specific policy, and discuss with the minor what will happen when they reach that age so there are no surprises.

Frequently Asked Questions

Can a minor open a checking account without a parent or guardian?

No. A minor cannot legally own a bank account, so a parent, guardian, or other adult must be the account owner. Some banks allow minors 16 and older to open accounts with a co-signer rather than a full custodian, but an adult must still be involved and responsible for the account.

What if the minor's parent is not a customer at the bank?

Most banks allow any adult to open a custodial account, regardless of whether they have an existing account. You will need to provide your own ID and proof of address. Some banks offer incentives (like a cash bonus) if you open a parent account at the same time, but it is not required.

Can a minor have their own debit card?

Yes. Most custodial accounts come with a debit card in the minor's name. The card is linked to the custodial account, so the parent can monitor and control spending through the bank's app. Some banks issue cards only to minors 13 and older, while others allow cards for younger children.

What if the minor's other parent wants access to the account?

Both parents can be listed as custodians on the same account if you both visit the bank together and both provide ID. This gives both parents equal access and control. If you are not married or do not live together, confirm with the bank whether both parents can be on the account, as policies vary.

Can the minor transfer money out of the account once they turn 18?

Yes. Once the account converts to an individual account in the minor's name, they have full control and can withdraw, transfer, or close the account without the parent's permission. If you want to protect funds for a specific purpose, a custodial account is not the right tool—a trust or 529 plan would be better suited.
