Yes, minors can have a checking account in California, but a parent or guardian must open it with them

A minor in California can have their own checking account, but they cannot open one alone. A parent or legal guardian must be present and sign the paperwork. The account will typically be set up as a custodial account or joint account, meaning the adult has legal control until the minor reaches the age of majority (18 in California). Different banks have different rules about the minimum age — some allow accounts for children as young as 6 or 7, while others require the minor to be at least 13.

The purpose of this setup is protection. The adult on the account can monitor spending, set limits, and help teach financial responsibility. Once the minor turns 18, they can convert the account to their own name and take full control, or they can open a separate account entirely.

Key Takeaways

  • A parent or legal guardian must open the account with the minor present; minors cannot open accounts on their own in California.
  • Most banks require the minor to be at least 13 years old, though some allow younger children with parental consent.
  • The account will be either custodial (parent has full control) or joint (both names on the account), depending on the bank.
  • At age 18, the minor can take sole control of the account or open a new one in their name only.
  • You will need the minor's Social Security number, proof of identity for both the parent and minor, and proof of address.

What documents you need to bring

When you and the minor go to the bank, bring a government-issued ID for yourself (driver's license or passport) and proof of your current address, such as a recent utility bill or lease. For the minor, bring their Social Security number or Individual Taxpayer Identification Number (ITIN), and a form of ID if the bank requires one — this might be a school ID, passport, or state ID card.

Some banks also ask for proof that you are the legal parent or guardian. If you are the biological parent, a birth certificate usually works. If you are a legal guardian, bring the guardianship paperwork. Call the bank ahead of time to ask what they specifically need; requirements vary between institutions.

The difference between custodial and joint accounts

A custodial account is held in the minor's name, but the parent is listed as the custodian. The parent can see all transactions and move money, but the account legally belongs to the child. When the minor turns 18, the custodial arrangement ends and they take full control. This is the most common setup for younger children.

A joint account has both the parent's and the minor's names on it. Both can withdraw money and make deposits. Joint accounts do not automatically convert when the minor turns 18 — the parent remains on the account unless you both go to the bank and remove them. Joint accounts are more common for teenagers who are old enough to manage money with parental oversight.

Ask the bank which type they offer for the minor's age. Some banks only offer custodial accounts for children under 13, and only offer joint accounts for teenagers.

Age requirements at major California banks

California banks do not have a single statewide rule for the minimum age. Each bank sets its own policy. Chase allows minors as young as 6 to open accounts with a parent. Bank of America requires the minor to be at least 8 years old. Wells Fargo requires 13. Credit unions in California often have different rules — some allow accounts for children as young as 5 or 6, while others require 13.

If you have a specific bank in mind, call their customer service line or visit a local branch and ask about their minimum age. Online banks often have different rules than branches, so check both if the bank offers online accounts. Some online banks do not offer accounts for minors at all.

What the minor can and cannot do

In a custodial account, the minor can usually make deposits and withdrawals at an ATM or in person, but the parent can see every transaction. The parent can also freeze the account or remove money if needed. The minor cannot take out a loan or overdraft the account without the parent's permission, and they cannot close the account on their own.

In a joint account, the minor has the same access as the parent — they can withdraw money, make transfers, and use the debit card. The parent can also do all of these things. Neither person can close the account without the other's consent, though the parent can usually remove the minor from the account.

Neither type of account reports to the minor's credit report. The account does not build credit history, so opening a checking account at age 10 or 15 will not help or hurt their credit score later. Credit history begins when they open their first credit card or loan in their own name, usually at 18 or older.

Converting the account when the minor turns 18

When the minor turns 18, contact the bank and ask how to convert the account. If it is custodial, the bank will remove the custodial status and the account becomes theirs alone. If it is joint, you can ask the bank to remove yourself from the account, or you can leave it as is if you both agree. Some banks require you to visit a branch in person to make this change; others allow it online or by phone.

The minor does not have to keep the same account after turning 18. They can open a new account at a different bank if they prefer. If they do keep the account, they will receive their own debit card and online login, and the parent will no longer have access unless the minor adds them back as an authorized user.

Why a checking account matters for teenagers

A checking account gives a teenager a place to deposit money from a job or allowance, and a way to learn how to manage money before they move out. It also gives them a debit card, which is safer than carrying cash and teaches them how to track spending. Many employers require direct deposit, so having a checking account makes it easier to get paid.

A checking account also teaches the habit of banking — knowing how to check a balance, understanding overdraft fees, and learning what happens when you spend more than you have. These lessons are easier to learn at 15 with a parent watching than at 22 when the stakes are higher.

Frequently Asked Questions

Can a minor open a checking account without a parent?

No. California law requires a parent or legal guardian to open the account with the minor. The minor cannot open an account alone at any age under 18. Some online banks advertise accounts for teens, but they still require a parent to set it up initially.

What happens to the account if the parent dies?

If the account is custodial, the minor's legal guardian (which may change if the parent dies) takes over as custodian. If the account is joint, the surviving parent or guardian remains on the account. Contact the bank as soon as possible with a death certificate so they can update the account records.

Can a minor have their own debit card?

Yes. Most banks issue a debit card for custodial and joint accounts. The card will have the minor's name on it. The parent can usually set spending limits through the bank's app or website, and can see every purchase the minor makes.

Do I need to be a customer at the bank to open an account for my minor?

No. You can open a new account for your minor even if you do not have an account at that bank. However, some banks offer discounts or easier approval if you are already a customer. Ask about this when you call to ask about their minimum age.

Can a minor have a savings account instead of a checking account?

Yes. Savings accounts work the same way as checking accounts — a parent must open it, and the minor can deposit and withdraw money. Savings accounts usually earn a small amount of interest, while checking accounts do not. Many minors have both: a checking account for spending and a savings account for money they want to keep.
