You cannot open a checking account in a newborn's name alone, but you can open a custodial account that the child will own when they turn 18

A custodial account is a bank account held in your child's name but managed by you as the parent or guardian until they reach the age of majority — usually 18 or 21, depending on your state. The money in the account legally belongs to the child from day one, even though you control it now. This is different from a regular joint account where both people own the money together.

Banks cannot open a standard checking account for someone who cannot sign their name or understand a contract. A newborn has no legal capacity to agree to the account terms. A custodial account solves this by letting you act on their behalf while keeping the money legally theirs.

The main reason parents open custodial accounts for newborns is to start building the child's financial history and teach money habits early. Some parents also use them to hold gifts from relatives or to set aside money for the child's future. When your child turns 18, the account becomes theirs to control completely, and you step out of the picture.

Key Takeaways

  • A custodial account is opened in your child's name with you as the manager, and the money legally belongs to the child from the start.
  • You will need your child's Social Security number, a birth certificate, and a government ID to open the account at most banks.
  • Custodial accounts earn very little interest at traditional banks, so some parents use them mainly to teach saving habits rather than to grow money.
  • When your child turns 18 or 21 (depending on your state), the account transfers to their full control and you can no longer access or manage it.
  • Some banks have no minimum balance for custodial accounts, while others require $25 to $100, so compare before you choose.

What documents you need to bring to the bank

To open a custodial account, bring your child's Social Security number or a letter from the Social Security Administration showing they have applied for one. If your child does not yet have a Social Security number, you can explore at your local Social Security office or online at ssa.gov. The process takes a few weeks, so plan ahead if you want the account open by a specific date.

You will also need your child's birth certificate (an original or certified copy) and your own government-issued photo ID, such as a driver's license or passport. Some banks ask for proof of address, like a utility bill or lease in your name. Call your bank ahead of time to ask what they specifically require — requirements vary between institutions.

Bring the child with you if possible, though not all banks require it. Some banks photograph the child as part of their process; others do not. Ask when you call to confirm whether you need to bring them in person or whether you can open the account by mail or online.

How custodial accounts work once they are open

Once the account is open, you deposit money and manage it exactly as you would your own checking account. You receive a debit card in your name (not the child's), and you use that card to withdraw money or make purchases. The child's name appears on the account statements, but the child cannot access the account until they turn 18.

You can add money to the account whenever you want — from your own savings, from gifts relatives send, or from money the child earns. There is no limit on how much you can deposit in a single year, though very large gifts may trigger tax reporting requirements. Talk to a tax professional if you are planning to deposit more than a few thousand dollars per year.

The money in the account is considered the child's asset for tax purposes. If the account earns interest or dividends, that income is reported on the child's tax return, not yours. At most banks, custodial checking accounts earn little to no interest, so this is rarely a concern. If you want the money to grow faster, you might consider a custodial savings account or investment account instead, though those are separate products.

What happens when your child turns 18

On the date your child reaches the age of majority in your state — usually 18, sometimes 21 — the account automatically transfers to their full control. You will no longer be able to access it, deposit money, or make withdrawals. The bank will send you and your child notice of this change, usually a few months before it happens.

Your child will receive their own debit card and online access. They can then use the account however they want, withdraw all the money, close it, or keep it open. You have no say in what they do with it once they turn 18. This is why some parents use custodial accounts as a teaching tool — the child learns that the money is theirs and they have to make decisions about it.

If you want to keep managing money for your child after they turn 18, you would need to open a separate joint account with them, and they would have to agree to it. A custodial account does not automatically convert to a joint account.

Custodial accounts versus other ways to save for a child

A custodial checking account is one option, but it is not the only way to set money aside for a child. A custodial savings account works the same way but usually earns a small amount of interest. A 529 plan is a tax-advantaged account designed specifically for education expenses. A Uniform Transfers to Minors Act (UTMA) account or Uniform Gifts to Minors Act (UGMA) account lets you hold investments like stocks or bonds in the child's name.

The main difference is purpose and control. A checking account is for money you want the child to access or learn to manage. A 529 plan is for education and has tax benefits but restrictions on how the money can be used. An UTMA or UGMA account is for longer-term investing but also transfers to the child's control at 18 or 21.

If you are opening an account mainly to teach your child about banking and saving, a custodial checking or savings account is the simplest choice. If you are setting money aside for college, a 529 plan may offer better tax treatment. If you want to invest in stocks or mutual funds on the child's behalf, an UTMA or UGMA account is more appropriate. Talk to your bank about which option fits your goals.

How custodial accounts affect financial aid and benefits

Money in a custodial account is counted as the child's asset when you explore for financial aid for college. This can reduce the amount of aid the child is offered, because colleges assume the child should use their own money first. The exact impact depends on how much is in the account and the college's financial aid formula.

If your child receives means-tested benefits like Supplemental Security Income (SSI) or Medicaid, a custodial account with more than a small amount of money may affect their benefits. SSI has strict limits on how much a person can own — currently $2,000 for an individual, though this amount can change. Before opening a custodial account for a child who receives SSI or similar benefits, talk to a benefits counselor or social worker to understand the impact.

For most families without special circumstances, a custodial account has no impact on benefits. But if your family receives any need-based government support, check before you open the account.

Where to open a custodial account

Most banks and credit unions offer custodial checking accounts. Call your current bank first — if you already have an account there, opening a custodial account for your child is usually faster and easier. Some banks waive fees or offer special rates for custodial accounts.

Online banks also offer custodial accounts, often with no monthly fees and no minimum balance. The trade-off is that you cannot walk into a branch to deposit cash or get help in person. If you prefer in-person service, a local bank or credit union is a better choice.

Compare a few options before you decide. Look at monthly fees, minimum balance requirements, whether the account earns interest, and whether you can deposit cash easily. Some banks charge $5 to $10 per month for custodial accounts; others charge nothing. Over 18 years, those fees add up.

Frequently Asked Questions

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

Many banks let you open a custodial account online, but some require you to come in person or mail in documents. Call your bank to ask. If you open online, you may need to mail in a copy of your child's birth certificate and your ID, and the bank will verify them before the account is active.

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

You can open the account as a joint custodian, which means both parents can access and manage it. The bank will ask both of you to sign the paperwork. If you are not married or do not have custody, talk to the bank about what documentation they need. This is a legal question, and the bank's requirements depend on your custody arrangement.

Can I use a custodial account to teach my child about money before they turn 18?

Yes. Many parents give their child a debit card linked to the custodial account once the child is old enough to understand money — around age 10 or 12. You can set spending limits and review transactions together. The account stays in your name legally, but you can use it as a teaching tool.

Do I have to put money in the account right away?

No. You can open the account with a small deposit or even no deposit at all, depending on the bank's minimum balance requirement. Some banks have no minimum for custodial accounts. You can add money whenever you want — there is no important date or schedule you have to follow.

What happens if I need to access the money for an emergency before my child turns 18?

You can withdraw money from the account anytime — it is your child's money, and you are the manager. However, the money is legally the child's, so using it for your own expenses (not the child's) can have tax or legal consequences. If you withdraw money for something other than the child's benefit, you may owe taxes on it. Use the account only for the child's needs or money you genuinely intend to give them.
