Yes, but the rules depend on your child's age and the bank

Your child can have their own bank account, but what "their own" means changes based on how old they are. A bank account for a 7-year-old looks completely different from one for a 16-year-old, and the bank gets to decide which option they offer.

Under age 18, your child cannot legally sign a contract, which is what opening a bank account technically is. So banks handle this in two ways: either you open an account in your name with your child as an authorized user, or you open a custodial account where you are the legal owner until they turn 18 or 21. Some banks also offer teen checking accounts that sit somewhere in between — your child has their own account number and debit card, but you retain access and control.

The account your child can actually use independently — where they alone can withdraw money and make decisions — does not exist until they are old enough to sign contracts themselves. That age varies by state and by bank, but it is typically 18.

Key Takeaways

  • Children under 18 cannot legally open a bank account alone; a parent or guardian must be involved, either as a co-owner or custodian.
  • Custodial accounts belong to the child but are controlled by you until they reach the age of majority, which is 18 in most states but can be 21 depending on the account type and bank.
  • Teen checking accounts let your child use a debit card and manage money with parental oversight, but the parent retains full access and control.
  • Once your child turns 18, they can open their own account without you, but some banks require them to visit in person or meet other conditions.

Custodial accounts: you control it until they are an adult

A custodial account is opened in your child's name, with you listed as the custodian. The money in the account legally belongs to your child, but you have complete control over it until they reach the age of majority. You can deposit money, withdraw it, and make decisions about how it is used. Your child cannot touch the account without your permission.

The age at which control transfers to your child depends on the account type and your state. For a standard custodial savings account, it is usually 18. For a custodial investment account (called a UTMA or UGMA account), it can be 21 in some states. Check with the specific bank about when control transfers — the rules are not the same everywhere.

Custodial accounts are useful if you want to set money aside for your child but keep it separate from your own accounts. They also teach your child that the money is theirs, even though you are managing it. The downside is that once your child turns 18 or 21, the money becomes fully theirs to use however they want — you lose control at that point.

Teen checking accounts: your child gets a card, you keep oversight

Many banks offer checking accounts designed for teenagers, usually starting around age 13. These accounts give your child their own debit card and the ability to make purchases and withdraw cash, but you retain full access to the account and can see all transactions. Some banks let you set spending limits or require approval for purchases over a certain amount.

Teen checking accounts are not legally separate from you — you are still the account owner, and your child is an authorized user. But the setup is designed to feel like their own account. Your child gets a card with their name on it, can check their balance, and learns to manage money in real time. You can monitor spending and step in if needed.

The features vary widely by bank. Some allow you to turn off certain types of transactions (like online purchases or ATM withdrawals). Others send you alerts for every purchase. A few let your child set their own PIN and use online banking independently, while you watch from a parent dashboard. Ask the bank what controls you get before you open the account.

Authorized user accounts: your child uses your account

The simplest option is to add your child as an authorized user on one of your existing accounts. Your child gets a debit card with their name on it and can make purchases and withdraw cash, but the account is yours. You see all transactions, and you can remove the card or close the account at any time.

This works well for younger children who just need a card for occasional purchases or allowance. It requires no separate paperwork or account opening. The downside is that there is no separation between your money and theirs — it is all in one account, which can make it harder for your child to understand how much money is actually theirs.

What happens when your child turns 18

At 18, your child can open a bank account in their own name without you. They can walk into a branch or open one online, depending on the bank. Some banks require you to be present or to sign off, but most do not once your child is 18.

If your child has a custodial account, it does not automatically transfer to them at 18. You will need to contact the bank and formally transfer ownership. Some banks do this automatically on the date your child turns 18; others require you to initiate it. Ask the bank what the process is when you open the account.

If your child has a teen checking account, you can keep it open and let them use it as their own, or you can close it and help them open a separate account. Some teens prefer to keep the account they are used to; others want a fresh start with their own account that feels completely theirs.

What documents you need to open an account for your child

To open any account for a minor, you will need to bring your child's Social Security number and proof of their identity. A birth certificate or passport works. You will also need your own ID and proof of your address (a utility bill or bank statement). Some banks also ask for your child's address, which is usually the same as yours.

For custodial accounts, the bank will ask you to confirm that you are the parent or legal guardian. You may need to bring a birth certificate or custody documents if there is any question about guardianship. Online account opening sometimes skips this step, but in-person opening usually requires it.

Teen checking accounts have similar requirements. Some banks let you open them online with just your child's Social Security number and your own ID. Others require you to visit a branch with your child present.

How to choose between these options

If your child is under 13 and you want them to have a card for occasional purchases, an authorized user account on your own account is the easiest choice. There is no paperwork, and you keep full control.

If your child is 13 to 17 and you want them to learn money management with some independence, a teen checking account gives them their own card and account number while you watch. This works well if you want to teach them about spending and saving without giving up oversight.

If you want to set money aside for your child that is legally theirs but controlled by you until they are an adult, a custodial account is the right choice. This is useful for savings you want to protect or money from gifts or inheritance.

Once your child is 18, they can open their own account. You can help them do it, but they do not need your permission or signature.

Frequently Asked Questions

Can my child use a teen checking account to build credit?

No. Debit cards do not build credit because there is no loan or payment history. Credit is built through credit cards, loans, or other credit products. A teen checking account teaches money management but does not affect your child's credit score. If you want your child to start building credit, you would need to add them as an authorized user on a credit card or help them open their own credit card at 18.

What happens to a custodial account if I die?

The money in the account belongs to your child, not to your estate. It passes directly to your child and is not part of your will. However, if your child is still a minor, the bank may require a new custodian to be named. Name a custodian in your will or contact the bank to update who can manage the account if something happens to you.

Can my child have a bank account without me knowing?

Not until they are 18. Before that, a parent or guardian must be involved in opening the account. Once they turn 18, they can open an account on their own, and you would have no way to know about it unless they tell you.

Do I have to give my child access to the money in their custodial account?

No. The money is theirs legally, but you control it until they reach the age of majority. You decide whether and how much to let them use. Some parents let their children access the money gradually; others keep it untouched until the child turns 18. The choice is yours while you are the custodian.

Can my child have multiple bank accounts?

Yes. Your child can have a checking account at one bank and a savings account at another. They can also have a custodial account and a teen checking account at the same time. There is no limit on the number of accounts, though managing multiple accounts can become confusing. Most families find one account per child is enough.
