Yes, but the account type depends on your child's age

A parent can open a checking account for a child, but the mechanics change based on whether the child is under 18 or older. For children under 18, you will open what banks call a custodial account or minor account — the parent or guardian is the legal account holder, and the child is an authorized user. The parent controls the account, can see all transactions, and is responsible for any overdrafts or fees. Once the child turns 18, most banks automatically convert the account to a standard checking account in the child's name alone, though some require you to visit a branch to complete the switch.

If your child is already 18 or older, you cannot open an account "for" them — they must open it themselves. You can be a co-owner or co-signer, which means you share legal responsibility for the account and can see transactions, but the account is in both your names. This is different from being an authorized user, where the account belongs to your child but you have access to manage it.

Key Takeaways

  • Parents can open custodial checking accounts for children under 18, with the parent as the legal owner and the child as an authorized user.
  • You will need the child's Social Security number, proof of identity for yourself, and proof of address to open a custodial account at most banks.
  • Custodial accounts automatically convert to standard accounts when the child turns 18, though the exact process varies by bank.
  • If your child is 18 or older, they must open the account themselves, but you can be added as a co-owner or authorized user after the account exists.
  • Monthly fees, overdraft policies, and minimum balance requirements for custodial accounts vary widely — compare banks before opening.

What you need to open a custodial account

To open a checking account for a child under 18, bring your government-issued ID (driver's license or passport), proof of your current address (a utility bill or lease dated within the last 60 days), and your child's Social Security number. Some banks also ask for the child's birth certificate. You do not need the child present at the branch, though some banks prefer it — call ahead to confirm your bank's policy.

Online banks have different requirements. Some allow you to open a custodial account entirely online using your ID and the child's Social Security number. Others require an in-person visit or do not offer custodial accounts at all. If you bank online, check the bank's website for "minor account" or "custodial account" to see whether they offer it and what documents they need.

How custodial accounts work once they are open

In a custodial account, you control all the money and all the decisions. You can deposit funds, withdraw money, set up automatic transfers, and close the account without the child's permission. The child's name appears on the account, and they may receive a debit card, but you decide whether they can use it and how much they can spend. Some parents give the child full access to the card; others restrict it or require approval for each purchase.

The account is held in trust for the child under your state's Uniform Transfers to Minors Act (UTMA) or Uniform Gifts to Minors Act (UGMA). This means the money legally belongs to the child, even though you control it. If you withdraw money for your own use, you are technically taking the child's money — though enforcement is rare unless there is a custody dispute or the child sues you later. The account does not revert to you if the child turns 18; it becomes the child's account outright.

What happens when your child turns 18

Most banks automatically convert a custodial account to a standard checking account on the child's 18th birthday. The account number usually stays the same, and any debit card remains active. After the conversion, you no longer have legal authority over the account — you cannot withdraw money, see transactions, or close it without the child's permission, even if you are listed on the account.

Some banks require a visit to the branch or a phone call to complete the conversion. A few banks ask the child to sign new documents or choose a PIN. Check with your bank 30 days before your child's 18th birthday to understand what will happen. If you want to remain involved in the account after the conversion, ask the bank about adding yourself as an authorized user or co-owner — but this requires the child's consent, and they can remove you at any time.

Fees and features to compare before opening

Custodial checking accounts are not all the same. Some banks charge a monthly maintenance fee ($5 to $15 is common), while others waive the fee if you maintain a minimum balance or set up direct deposit. Overdraft policies vary: some banks decline transactions that would overdraw the account, while others allow the overdraft and charge a fee ($25 to $35 per incident). A few banks offer overdraft protection, which links the account to a savings account and automatically transfers money to cover shortfalls.

Compare the debit card features too. Some cards allow ATM withdrawals at any bank's ATM for free; others charge $2 to $3 per out-of-network withdrawal. Some cards come with fraud protection and purchase protection; others do not. If you plan to give your child spending money through the account, a card with no monthly fee and no ATM fees will cost less over time than one with both.

Opening an account for a child who is already 18

If your child is 18 or older, they must open the account themselves — you cannot do it for them. However, you can be added to the account as a co-owner or authorized user after it is open. A co-owner has equal legal rights: you can both deposit, withdraw, and close the account. An authorized user can access the account and make transactions, but the account legally belongs to your child, and they can remove you without notice.

Your child can add you to an existing account by visiting the bank in person or, at some banks, through the online portal. Bring your ID and Social Security number. The process usually takes a few minutes. If you want to open a joint account from scratch, both of you must visit the branch together or complete the process together online, depending on the bank's policy.

Frequently Asked Questions

Can I open a custodial account online, or do I have to go to a branch?

Many online banks allow you to open a custodial account entirely online using your ID and your child's Social Security number. Traditional banks usually require an in-person visit to the branch. Call your bank or check their website for "minor account" to see what they require.

What happens to the money in the account if I die?

The money belongs to your child, not to your estate. It will not go through probate. However, if your child is very young, the court may appoint a guardian to manage the account until they turn 18. Name a backup guardian in your will to avoid a court process.

Can my child use the debit card without my permission once they turn 18?

Yes. Once the account converts to their name alone, they have full control. If you want to stay involved, ask them to add you as an authorized user or co-owner — but they can refuse or remove you at any time.

Do I have to report the money in a custodial account on my taxes?

The money belongs to your child, so they may owe tax on any interest or investment earnings the account generates. The rules depend on how much income the account earns and your child's age. Consult a tax professional for your specific situation.

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

Only the person whose name is on the account as the owner can control it. If both parents want access, you can open a joint custodial account with both parents listed as owners. Both of you will have equal rights to the account. Some banks allow this; others do not — ask before opening.
