Yes, minors can open a checking account in California, but a parent or guardian must be on the account

A minor under 18 cannot open a checking account alone in California. Every bank and credit union requires a parent or legal guardian to be a joint account holder, meaning both names appear on the account and both can access the funds. The adult is legally responsible for the account and any overdrafts or fees.

The specific rules vary slightly by institution. Some banks allow minors as young as 13 to have a junior checking account with parental oversight. Others require the minor to be 16 or older. A few banks set no age minimum as long as the parent opens it with them. You will need to contact your bank directly to learn their policy, since California law does not set a single age requirement—banks set their own.

The account belongs to both of you until the minor turns 18. At that point, the young person can usually convert it to a solo account, remove the parent as a signer, or open a separate account elsewhere. Some banks do this automatically; others require a visit or a phone call to make the change.

Key Takeaways

  • A parent or legal guardian must open the account jointly with the minor and remain on it until the minor turns 18.
  • Age requirements for minors range from 13 to 16 depending on the bank, so you will need to check with your specific institution.
  • You will need the minor's Social Security number, proof of identity for both the parent and minor, and proof of the parent's address.
  • Most banks allow the account to convert to a solo account when the minor reaches 18, though the process and timing vary by bank.

What documents you need to bring

Both the parent and the minor must provide identification. For the minor, this is usually a school ID, passport, or California ID card. For the parent, a driver's license or passport works. You will also need the minor's Social Security number and proof of the parent's current address—a utility bill, lease, or recent bank statement dated within the last 60 days.

Some banks ask for additional documents if the parent is not the biological parent. If you are a legal guardian, grandparent, or other relative, bring the guardianship papers or custody order. If the account will receive direct deposit (for example, from a job or allowance), have that employer or payer information ready, though it is not required to open the account.

Call your bank before you visit to confirm what they need. Requirements can differ between branches, and some banks let you start the process online and finish in person, while others require you to come in from the start.

Banks and credit unions that offer accounts for minors in California

Most major banks allow minors to open checking accounts with a parent. Chase, Bank of America, Wells Fargo, and Citibank all offer junior or teen checking accounts, though each has different age minimums and features. Credit unions often have lower fees and simpler rules—many California credit unions allow minors as young as 13 to open accounts with a parent.

Online banks like Ally, Charles Schwab, and Fidelity also offer accounts for minors, though the process is entirely digital and may require the parent to verify their identity through video or document upload. These banks often have no monthly fees and no minimum balance, which can make them cheaper than traditional banks.

If the minor already has a savings account at a bank, opening a checking account at the same place is usually faster because the bank already has their information on file. If you are starting from scratch, compare a few options: look at monthly fees, overdraft policies, debit card features, and whether the bank offers tools to teach money management (some let parents set spending limits or receive alerts).

What happens when the minor turns 18

The account does not automatically close or convert. Instead, you have a window of time—usually 30 to 90 days after the minor's 18th birthday—to decide what happens next. The young person can remove the parent as a signer and take over the account solo, or the parent can stay on if both agree. Some banks require a visit to the branch to make this change; others allow it online or by phone.

If neither of you takes action within the bank's timeframe, the account usually stays as-is with both names on it. This is not a problem unless the young person wants to move banks or the parent wants to be removed. At that point, you will need to contact the bank to make the change official.

The young person's credit history does not automatically start when they turn 18 just because they have a checking account. A checking account does not build credit. If they want to start building credit, they will need a credit card, loan, or other credit product, and the parent may need to co-sign or be a co-applicant depending on the lender.

Overdraft and fee protections for minor accounts

Minor accounts often have different overdraft rules than adult accounts. Many banks do not allow overdrafts on junior checking accounts at all—the debit card straightforward declines if there is not enough money. Others allow small overdrafts but charge a fee (usually $25 to $35 per overdraft). A few banks let the parent set a spending limit so the minor cannot spend more than a certain amount per day or per transaction.

Monthly maintenance fees vary widely. Some banks charge $5 to $10 per month for a minor account; others charge nothing. A few waive fees only if the account receives direct deposit or maintains a minimum balance. Read the fee schedule before you open the account, because switching banks later is possible but takes time.

California law does not cap overdraft fees for minors, so the bank's own policy is what matters. If overdraft fees are a concern, look for a bank that either does not allow overdrafts or offers overdraft protection (a link to a savings account or parent's account that covers shortfalls).

Opening the account in person versus online

Most banks require at least one visit to a branch to open a minor's account, even if you start the process online. The bank needs to verify the minor's identity in person and confirm that the parent is actually the parent (or legal guardian). Some banks will video-verify instead if you do not have a nearby branch, but this is less common.

Online banks like Ally and Charles Schwab can complete the entire process remotely using document upload and video verification, which takes 10 to 15 minutes. However, these banks do not have physical branches, so if the minor needs help later, you will be on the phone or chat with customer service.

If you go to a branch, bring all documents and both the parent and minor if possible. Some banks allow the parent to open the account alone and add the minor later, but this takes an extra step. Bring a list of questions about fees, overdraft rules, and the conversion process at age 18, because the person opening the account may not volunteer this information.

Frequently Asked Questions

Can a minor open a checking account without a parent?

No. California law and all banks require a parent or legal guardian to be a joint account holder. The minor cannot be the sole owner until they turn 18.

What if the parent does not have a Social Security number?

The parent will need an ITIN (Individual Taxpayer Identification Number) or passport to open the account. Some banks accept an ITIN; others do not. Call ahead to confirm your bank's policy.

Can the minor use the debit card without the parent's permission?

Yes. Once the account is open, the minor can use the debit card to make purchases and withdraw cash. The parent can set spending limits on some accounts, but this is optional and depends on the bank.

What if the parent wants to remove themselves from the account before the minor turns 18?

Most banks do not allow this because the parent is legally responsible for the account. You would need to close the account and open a new one with a different adult, or wait until the minor turns 18. Contact your bank to ask about exceptions.

Do I need to open the account at the same bank where the parent has an account?

No. The parent and minor can open an account at any bank, regardless of where the parent banks. However, opening at the same bank is sometimes faster because the bank already has the parent's information.
