Who can open an account and what you'll need

You cannot open a checking account in your nephew's name without him present, even if you're his guardian. Banks require the account holder to sign documents in person or electronically verify their identity themselves. If your nephew is a minor, you can open a custodial account — a checking account in his name with you as the custodian — but the bank will still need him to be present or to verify his identity through their online process.

The age at which a minor can open an account varies by bank. Most banks allow accounts for children as young as 13 or 14 with a parent or guardian present. Some banks, like Ally and Charles Schwab, let younger children open accounts (sometimes as young as 6 or 8) if a parent or guardian co-owns the account. A few banks have no age minimum if a parent or guardian is the primary account holder.

You'll need your nephew's Social Security number, a form of ID (a school ID, passport, or state ID if he has one), and proof of address. If you're the custodian, bring your own ID and Social Security number as well. Some banks accept a utility bill or lease in your name as proof of address; others accept mail from a government agency.

Key Takeaways

  • Your nephew must be present or verify his identity himself — you cannot open an account in his name alone, even as his guardian.
  • A custodial account is held in your nephew's name with you as custodian, and most banks allow these for children 13 and older.
  • Some banks allow custodial accounts for younger children (6 to 12) if a parent or guardian co-owns the account instead.
  • You will need your nephew's Social Security number and ID, plus your own ID and proof of address.
  • At age 18 or 21 (depending on the bank), your nephew becomes the sole owner and you lose custodial rights.

Custodial accounts versus co-owned accounts

A custodial account is registered in your nephew's name, with you listed as custodian. Your nephew is the legal owner. You can deposit money, make withdrawals, and manage the account while he is a minor. When he reaches the age of majority (18 in most states, 21 in a few), the account automatically converts to his sole ownership and you lose all control. This is the standard structure for minors' accounts at most banks.

A co-owned account lists both you and your nephew as owners with equal rights. Either of you can withdraw money or close the account. Co-owned accounts do not automatically convert — you remain an owner unless you formally remove yourself. Co-owned accounts are less common for minors because they give the child full access to the money before they reach adulthood, and they complicate things if you and your nephew later disagree about the money.

If your nephew is very young (under 13), a co-owned account may be your only option at some banks. Ask the bank directly whether they offer custodial accounts for his age, or whether a co-owned account is required.

What happens when your nephew turns 18

On the date your nephew reaches the age of majority (usually 18), the custodial account converts to a regular checking account in his name alone. You are removed as custodian automatically — you will no longer see the account online, receive statements, or have any legal right to the money. The bank sends notice of this conversion to both you and your nephew, usually 30 to 60 days before it happens.

Your nephew does not have to do anything for the conversion to occur. The account stays open, the card stays active, and his money remains his. If you want to discuss what happens to the account after the conversion, have that conversation with him before his 18th birthday. Some families agree to keep the account open as a joint account after conversion; others close it and open a new one in his name alone.

Banks that make minor accounts straightforward

Large national banks like Chase, Bank of America, and Wells Fargo all offer custodial checking accounts, but they often require you to visit a branch in person. Online banks like Ally, Charles Schwab, and Fidelity allow you to open custodial accounts online, though they still require your nephew to verify his identity (usually by uploading an ID photo or answering security questions).

Credit unions often have simpler processes for minors' accounts and may charge lower fees. If your nephew's school or your employer has a credit union, check whether they offer youth accounts — many do, and they often come with educational tools about money management.

Some banks market accounts specifically for teens and include features like spending limits, parental alerts when money is withdrawn, and financial literacy resources. These accounts cost the same as regular checking accounts but give you more visibility into how your nephew is using the money.

Fees and account features to compare

Most custodial checking accounts have no monthly fee, but some banks charge $5 to $15 per month if you don't meet a minimum balance (usually $100 to $500). A few banks waive fees for accounts opened by minors regardless of balance. Ask whether the bank charges fees for overdrafts, out-of-network ATM use, or paper statements.

Compare whether the account comes with a debit card, how quickly your nephew can access money online, and whether the bank offers parental controls (alerts when money is spent, the ability to set spending limits, or the option to block certain types of transactions). If your nephew is old enough to use the account himself, check whether the bank's mobile app is easy to navigate.

Some banks offer interest on checking account balances, though the rate is usually very low (0.01% to 0.05% annually). This matters more for savings accounts, but it's worth noting if your nephew will be keeping a large balance.

What you can and cannot do as custodian

As custodian, you can deposit money into the account, withdraw money, pay bills from the account, and manage it online or by phone. You can also close the account before your nephew turns 18, though this is unusual and may require his consent depending on the bank's policy.

You cannot use the money in the account for your own expenses — the money belongs to your nephew, and using it for yourself is considered a breach of your custodial duty. You also cannot transfer the account to yourself or change the ownership structure without the bank's involvement. If you need to step down as custodian before your nephew turns 18, you'll need to name a replacement custodian (usually a parent or another guardian) and the bank will process the change.

The account is your nephew's property for tax purposes. If the account earns interest or investment income, your nephew may owe taxes on it. The bank will send a 1099 form if interest exceeds a certain threshold (currently $10 annually, though this can change).

How to start the process

Call or visit the bank's website to confirm they offer custodial accounts for your nephew's age. Ask what documents you'll both need to bring and whether you can open the account online or must visit a branch. If opening online, the bank will walk you through uploading documents and verifying identity.

Bring your ID, your nephew's ID, both Social Security numbers, and proof of address. If you're opening the account in person, the process usually takes 15 to 30 minutes. If opening online, it may take a few days for the bank to verify documents and activate the account.

Once the account is open, set up online access so you can monitor deposits and withdrawals. Decide with your nephew whether he will have his own debit card and online login, or whether you'll manage the account for him until he's older. This depends on his age and maturity level.

Frequently Asked Questions

Can I open a checking account for my nephew if I'm not his parent or legal guardian?

No. Only a parent, legal guardian, or court-appointed custodian can open a custodial account for a minor. If you are not one of these, the parents or guardians must open the account themselves. You can offer to help pay for it or contribute money after it's open, but you cannot be the custodian.

What if my nephew is 18 or older?

Once your nephew turns 18, he can open a checking account on his own without you present. He will need his ID, Social Security number, and proof of address. You can help him choose a bank or go with him, but he is the sole account holder and you have no custodial rights.

Can my nephew access the money in his custodial account whenever he wants?

Yes. He can withdraw money using a debit card, ATM, or by asking you to withdraw it for him. Some parents and guardians set spending limits or require the child to ask permission before withdrawing large amounts, but the bank does not enforce these rules — they are family agreements.

What if I want to close the custodial account before my nephew turns 18?

You can close the account, but the money belongs to your nephew. The bank will require you to decide what to do with the balance — you can transfer it to another account in his name, give it to him in cash, or move it to a savings account. You cannot keep the money for yourself.

Do I have to report the custodial account to anyone?

No, unless the account earns interest or investment income above a certain threshold. The bank will send a 1099 form if that happens, and your nephew may owe taxes on the income. You do not need to report the account to government agencies or file special paperwork just for opening it.
