Yes, minors can own bank accounts, but an adult must open and manage it

A minor — anyone under 18 in most states — cannot walk into a bank alone and open an account. Banks require the account owner to be able to sign contracts and understand the legal obligations involved, which the law says minors cannot do. Instead, a parent or legal guardian must open the account with the minor present, and that adult becomes a co-owner or custodian who can access and control the money.

The account itself belongs to the minor, but the adult has legal authority over it. This means the adult can deposit money, withdraw money, and make decisions about how it is used — at least until the minor turns 18. At that point, the minor can take full control, though the adult's name may stay on the account unless both parties agree to remove it.

Different banks have different rules about what happens when the minor reaches adulthood, so it is worth asking about this when you open the account. Some banks automatically convert the account; others require you to visit in person or sign new paperwork.

Key Takeaways

  • A parent or legal guardian must open a minor's bank account in person, and the adult becomes a co-owner with full access to the money.
  • The account is held in the minor's name, but the adult controls it until the minor turns 18 or reaches the age of majority in your state.
  • Most banks offer youth accounts or teen accounts with lower fees and spending limits designed for minors learning to manage money.
  • When the minor turns 18, you should ask the bank what happens next — some accounts convert automatically, while others require new paperwork.
  • The adult on the account is legally responsible for any overdrafts or fees, so choose an adult the minor trusts and who will teach good banking habits.

What documents you need to open a minor's account

Bring the minor's Social Security number or Individual Taxpayer Identification Number (ITIN), a government-issued ID for the adult (driver's license or passport), and proof of address for the adult — usually a recent utility bill or lease. Some banks also ask for the minor's birth certificate, though not all do.

Both the adult and the minor must be present at the bank. The adult will sign the account paperwork; the minor may be asked to sign as well, depending on the bank's policy. The bank will explain what the account includes — whether it has a debit card, what the overdraft rules are, and whether there are monthly fees.

If you are opening the account online or by mail, the process is different and usually slower. You may need to mail in copies of documents or use a video call to verify identity. Ask the bank whether they offer this option before you visit in person.

The difference between custodial accounts and joint accounts

Most banks offer two ways to set up an account for a minor: a custodial account or a joint account. The names sound similar, but they work differently.

In a custodial account, the adult is the custodian — a legal role that means the adult holds and manages the money for the minor's benefit. The account is in the minor's name, and the money legally belongs to the minor, but the adult controls it. When the minor turns 18 or 21 (depending on your state and the bank), the account automatically transfers to the minor's full control. The adult's job ends.

In a joint account, both the adult and the minor are owners with equal rights. Both can deposit and withdraw money. The account does not automatically change when the minor turns 18 — both names stay on it unless you go back to the bank and change it. Joint accounts are simpler to set up but can cause confusion later about who owns what.

For a young child learning to save, a custodial account is usually the better choice because it is clear that the money is being held for the child. For a teenager who is working and managing their own money, a joint account might make more sense because it treats them more like an adult.

What happens when the minor turns 18

The answer depends on the type of account and the bank's rules. With a custodial account, the bank will contact you before or after the minor's 18th birthday to explain what happens next. Some banks automatically convert it to a regular adult account in the minor's name alone. Others require you to visit the bank or sign new paperwork. A few banks close custodial accounts and ask you to open a new adult account.

With a joint account, nothing happens automatically. Both names stay on the account unless you ask the bank to remove the adult. This can be useful if the adult wants to keep an eye on the account, but it also means the adult can still withdraw money without the minor's permission — which may not be what either of you wants.

Before the minor's 18th birthday, ask your bank in writing what their policy is. Get the answer in writing so you have it when the time comes. If the bank's process is complicated or requires a visit, you can plan ahead.

Fees and features to compare across banks

Youth accounts and teen accounts vary widely. Some banks charge no monthly fee; others charge $5 to $10 per month. Some offer a debit card; others do not. Some allow the minor to set up online banking; others restrict it until age 16 or 18. Some have spending limits or require the adult to approve certain transactions.

Before you open an account, ask the bank about overdraft fees. If the minor spends more than is in the account, will the bank deny the transaction, or will it charge a fee? Some banks charge $35 per overdraft; others charge nothing. For a young person learning to manage money, a bank that denies the transaction is often better than one that charges a fee.

Ask whether the account earns interest. Most youth accounts earn very little — sometimes less than 0.01 percent per year — but some online banks offer higher rates. If the minor is saving for something specific, even a small difference adds up over time.

How the adult's credit is affected

Opening a custodial or joint account for a minor does not affect the adult's credit score. Banks do not report these accounts to credit bureaus the way they report credit cards or loans. The account will show up on the adult's bank statements and tax returns if there is interest earned, but it will not change the adult's credit history.

However, if the account goes overdrawn and the bank sends it to a collection agency, that could affect the adult's credit. This is rare with youth accounts because they usually have low balances and spending limits, but it is possible. Choose a bank with clear overdraft rules so you know what will happen if the account runs negative.

Teaching a minor to use the account responsibly

An account is a tool for learning. Before the minor gets a debit card, talk about what it is for. Is it for saving allowance? For spending money from a job? For learning how to budget? The clearer the purpose, the easier it is to set rules.

Set up online banking so the minor can see the balance and recent transactions. Many banks allow you to set alerts — the bank will send a text or email if the balance drops below a certain amount, or if a large purchase is made. These alerts help the minor notice mistakes or fraud quickly.

If the account has a spending limit or requires the adult to approve transactions, use that feature while the minor is learning. As they show they understand how to manage money, you can relax the rules. By the time they turn 18, they should know how to check their balance, understand fees, and avoid overdrafts.

Frequently Asked Questions

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

No. Banks require the account owner to be able to sign a contract, which minors legally cannot do. A parent, legal guardian, or in some cases a grandparent or other adult with legal authority must open the account with the minor present.

What if the adult on the account dies or becomes unable to manage it?

The account does not automatically close, but it may be frozen while the bank figures out what to do. If the adult named a beneficiary or left a will that addresses the account, the bank will follow those instructions. If not, the account may go through probate. To avoid this, talk to a lawyer about naming a backup custodian or setting up the account in a way that passes to someone else if the first adult cannot manage it.

Can a minor have their own account without an adult on it?

Not at a traditional bank. Some online services and fintech apps offer accounts for minors without an adult co-owner, but these are not FDIC-insured bank accounts — they are prepaid cards or digital wallets. If safety and insurance matter to you, stick with a bank account where an adult is listed as the custodian or co-owner.

Does the minor need permission to spend money from their own account?

That depends on the account type and the bank's rules. In a custodial account, the adult is supposed to approve spending that is not for the minor's benefit, but in practice, if the minor has a debit card, they can spend without asking. In a joint account, both owners have equal rights to the money. If you want to require approval, ask the bank whether they offer transaction limits or alerts.

What happens to the money in the account if the minor moves away or goes to college?

The money stays in the account and belongs to the minor. If the minor is 18 or older, they have full control. If they are still under 18, the adult custodian still has authority. The account can stay open and be used from anywhere, though some banks may ask for updated contact information if the address changes.
