Yes, but the rules depend on her age and which parent has legal authority
You can open a bank account for your niece, but the bank will require either her parent or legal guardian to sign off on it. If she is under 18, the account will be a custodial account or minor account, meaning a parent or guardian must be listed as the account owner alongside her, or must authorize the account in writing. You cannot open an account in her name alone without parental consent, even if you are providing the money.
The specific rules vary by bank and by state. Some banks allow a minor to be the sole account holder once she reaches a certain age—often 13 or 14—if a parent or guardian has opened it first. Others require a parent or guardian to remain on the account until she turns 18. A few banks will let you open a savings account for a minor without the parent present if you have written authorization, but this is less common.
If your niece is 18 or older, you can open an account with her directly, and no parental permission is needed. She will need to provide her own identification and Social Security number.
Key Takeaways
- A parent or legal guardian must authorize any account opened for a minor, either by signing in person or by providing written consent.
- Custodial accounts remain under parental control until the minor reaches the age of majority, which is 18 in most states.
- Different banks have different rules about whether a parent must stay on the account after the minor turns 13 or 14, so call ahead to ask.
- If your niece is 18 or older, she can open an account herself with just her ID and Social Security number.
- You will need her Social Security number, date of birth, and address to open any account, whether or not a parent is present.
What documents you need to bring
To open a custodial account for your niece, bring the parent or guardian's government-issued photo ID (driver's license, passport, or state ID card), your niece's birth certificate or Social Security card, and proof of address for the parent—usually a recent utility bill, lease, or mortgage statement. Some banks will accept a school ID or report card as proof of the minor's identity instead of a birth certificate.
If the parent cannot come in person, call the bank first to ask whether they accept a notarized authorization letter. If they do, the parent will need to sign the letter in front of a notary public (available at most banks, credit unions, UPS stores, and some law offices). The notary will charge a small fee, usually $5 to $15. Bring the notarized letter, your ID, and your niece's documents to the bank.
Have your niece's Social Security number ready. If she does not have one yet, the parent will need to apply for it through the Social Security Administration before opening the account. This takes about two weeks.
Types of accounts available for minors
Most banks offer a savings account for minors, which earns a small amount of interest and has no monthly fee. Some also offer a checking account for minors, which comes with a debit card and allows your niece to make purchases and withdrawals. Checking accounts for minors sometimes have limits on how much can be withdrawn per day or how many transactions are allowed per month.
A few banks offer teen checking accounts starting at age 13, which give the minor more independence while keeping parental oversight. These usually include a debit card, online banking access, and the ability to set up direct deposit for allowance or earnings. The parent can still see all transactions and set spending limits.
Credit unions often have similar options and may offer slightly higher interest rates on savings. Ask your bank or credit union what accounts they offer for minors and what the fees, interest rates, and transaction limits are.
Who controls the account while your niece is a minor
Until your niece reaches the age of majority—18 in most states, 19 in Alabama and Nebraska, 21 in Mississippi—the parent or guardian on the account controls all deposits, withdrawals, and decisions about the account. Your niece can use the debit card (if the account has one) to make purchases, but the parent can see every transaction and can freeze or close the account at any time.
If you are the one depositing money into the account, understand that once the money is in, the parent has full legal control over it. You cannot restrict how the parent uses the funds or require that the money be saved for a specific purpose. If you want to set aside money for your niece's future and keep it separate from parental control, a 529 education savings plan or a Uniform Transfers to Minors Act (UTMA) account may be better options, though these have different rules and tax implications.
What happens when your niece turns 18
When your niece reaches 18, the account automatically converts to an adult account in her name alone, and the parent's access ends. She becomes the sole owner and can withdraw all funds, close the account, or change the account settings without parental permission. Some banks send a notice before this happens; others do not, so your niece should be aware that this transition is coming.
If your niece wants to keep the account open after turning 18, she does not need to do anything—the conversion is automatic. If the parent wants to stay on the account after she turns 18, both of them must agree and visit the bank together to update the account structure. This is now a joint account between two adults, not a custodial account.
Alternatives if the parent will not consent
If your niece's parent refuses to authorize an account, you have limited options. You cannot legally open an account in her name without parental consent. However, you can open a savings account in your own name and set it aside for her, though this does not give her direct access or teach her about banking.
If there is a court order granting you legal guardianship or custody of your niece, you can open an account as her guardian without the biological parent's consent. Bring the custody order or guardianship papers to the bank along with her birth certificate and Social Security number.
If your niece is 18 or older and wants an account but has no ID, she can apply for a state ID card through your state's Department of Motor Vehicles. This usually takes one to two weeks and costs $10 to $30.
Frequently Asked Questions
Can I put money into an account for my niece without opening an account in her name?
Yes. You can open a savings account in your own name and set aside money for her, or you can give cash or a gift card directly to her or her parent. However, this does not teach her about banking or give her control over the money. If you want her to learn to save and manage money, a custodial account in her name is more useful.
What if my niece's parents are divorced and disagree about the account?
The bank will require consent from the parent with legal custody, as stated in the custody order. If custody is shared equally, most banks will accept consent from either parent. Bring a copy of the custody order to the bank so they know which parent has authority to sign.
Can my niece use the debit card without the parent's permission?
Yes, if the account includes a debit card, she can use it to make purchases up to the daily limit set by the bank or the parent. However, the parent can see all transactions and can cancel the card or freeze the account at any time.
Do I need to be present when the account opens?
No. The parent or guardian must be present or provide written authorization, but you do not need to be there. You can give the parent the money to deposit, or you can deposit it yourself after the account is open if you have access to online banking or a debit card linked to the account.
What happens if the parent closes the account before my niece turns 18?
The parent can close the account and withdraw all funds at any time. If you have deposited money into the account, you have no legal claim to it once it is in the account under the parent's control. If you want to protect money set aside for your niece, consider a 529 plan or UTMA account instead.
