Yes, but the bank will treat you as equal owners with full access

A mother and son can open a joint bank account together at most banks and credit unions. Both of you will have equal legal rights to the money in the account — either person can deposit, withdraw, or close the account without permission from the other. The bank does not distinguish between you based on age or relationship; once the account is open, you are co-owners with identical powers.

This matters because it means the son can access all the money even if the mother deposited it, and the mother cannot prevent the son from withdrawing funds. If your goal is to give your son access to money for a specific purpose — like paying for college or managing household expenses — a joint account works. If your goal is to keep money separate while letting him use it only under certain conditions, a joint account will not do that.

Key Takeaways

  • Both the mother and son become equal owners of all money in the account, with no restrictions on who can withdraw what.
  • Most banks require both people to be present at the branch to open the account, though some allow online opening if both sign electronically.
  • The account will report to both people's credit reports and tax records, so large deposits or interest may affect each person's finances.
  • If the mother dies, the money in a joint account passes directly to the son outside of probate, which is often why parents choose this structure.
  • A joint account is different from a custodial account (for minors) or a power of attorney, both of which give more control to one person.

What you need to bring to open the account

Both the mother and son must show up at the bank branch with government-issued photo ID — a driver's license, passport, or state ID card. The bank will verify both identities before opening the account. Some banks now allow joint account opening online if both people can sign electronically using their ID, but this varies by bank and state.

You will also need to choose what type of account you want: checking, savings, or money market. The bank will ask how you want the account titled — usually "Mother Name and Son Name, Joint Tenants with Rights of Survivorship" or "Joint Tenants in Common," depending on what you want to happen to the money if one person dies. Ask the bank to explain the difference for your state, because the rules vary.

If the son is under 18, some banks will not open a joint account with an adult; they will instead offer a custodial account where the parent controls the money until the child reaches the age of majority (usually 18 or 21). Check with your bank about their age policy before you go in.

How the bank reports the account to the IRS and credit bureaus

The bank will report the account to both the mother's and son's tax records. If the account earns interest, the bank sends a 1099-INT form to both people, and you will need to report that income on your tax returns. The IRS does not care who deposited the money or who withdrew it — both owners are responsible for reporting the interest.

Joint accounts do not appear on credit reports the way credit cards do, so opening one will not help or hurt either person's credit score. However, if the account goes negative or is sent to collections, it can damage both people's credit. Banks also report joint accounts to ChexSystems, a checking account history database that other banks use to decide whether to open accounts for you.

What happens if one person dies

If the account is titled "Joint Tenants with Rights of Survivorship," the money passes directly to the surviving owner outside of probate. This means the son would own the account immediately after the mother's death without waiting for a will to be processed or a court to approve it. This is one of the main reasons parents open joint accounts with adult children.

If the account is titled "Joint Tenants in Common," the mother's share of the account becomes part of her estate and goes through probate, even though the son is a co-owner. The rules for this vary by state, so ask the bank which title option applies in your state and what it means for your situation.

Risks of a joint account between a mother and son

The biggest risk is that either person can take all the money without the other's permission or knowledge. If the son faces a lawsuit, creditor claim, or bankruptcy, the money in the joint account may be seized to pay his debts — even if the mother deposited every dollar. The same applies in reverse: if the mother owes money, creditors can go after the joint account.

A joint account also means both people's names appear on bank statements and tax documents. If the son has a spouse and later divorces, the joint account with his mother may be considered a marital asset in the divorce, depending on state law. If either person has a substance abuse problem or poor financial judgment, a joint account gives them direct access to the other person's money.

If the mother wants to leave money to the son in her will but also protect it from his creditors or ex-spouse, a joint account is not the right tool. A trust, a payable-on-death account, or a custodial account would offer more protection.

Alternatives if a joint account does not fit your situation

A payable-on-death (POD) account lets the mother keep the account in her name alone, with the son named as the beneficiary. The son has no access while the mother is alive, but the money passes to him automatically after her death without probate. This protects the money from the son's creditors during the mother's lifetime.

A custodial account works if the son is a minor. The mother acts as custodian and controls the money until the son reaches the age of majority, at which point he owns it outright. Once he turns 18 or 21 (depending on state law), he can withdraw the money without the mother's permission.

A power of attorney lets the mother keep the account in her name alone while giving the son legal authority to manage it on her behalf. The son can deposit and withdraw money, but the account remains the mother's property. If the mother dies, the power of attorney ends and the account goes through probate or to whoever is named in her will.

A revocable living trust lets the mother fund an account in the trust's name, name the son as successor trustee, and control who gets the money after her death. The son has no access while the mother is alive unless she specifically grants it, and the money avoids probate.

How to close a joint account or remove someone

Either person can close the joint account at any time by going to the bank and requesting closure. The bank will ask what to do with the remaining balance — deposit it to another account, issue a check, or split it between the two owners. Some banks require both owners to be present to close the account; others allow one owner to close it unilaterally. Call your bank to ask their policy.

You cannot remove one person from a joint account and keep it open; you have to close the account and open a new one in the remaining person's name alone. If the mother wants to remove the son from the account, she closes the joint account and opens a new account in her name only. The son will no longer have access to any money in the new account.

Frequently Asked Questions

Can a mother open a joint account with a son without him knowing?

No. Both people must be present at the bank with photo ID, or both must electronically sign the account opening documents. The bank verifies both identities before creating the account. If the son is not physically present or does not sign, the account cannot be opened as a joint account.

What if the son is under 18?

Most banks will not open a joint account with a minor and an adult. Instead, they offer a custodial account where the parent controls the money until the child reaches 18 or 21. At that age, the account automatically becomes the child's property. Ask your bank about their specific age policy.

Does opening a joint account affect the son's student loans or financial aid?

Yes. Money in a joint account is counted as an asset on the Free Application for Federal Student Aid (FAFSA), which can reduce the amount of aid the son is offered. The impact depends on whose name the account is in and how much money is there. Talk to the financial aid office before opening a joint account if the son is in school or planning to attend.

Can the mother close the account if the son is spending the money recklessly?

Yes, the mother can close the joint account at any time. However, she cannot prevent the son from withdrawing money while the account is open. If the mother wants ongoing control over how the money is used, a joint account is not the right structure — a power of attorney or custodial account would work better.

What happens to the joint account if the mother declares bankruptcy?

The money in the joint account may be considered part of the mother's bankruptcy estate and used to pay her debts, even if the son deposited the money. Creditors can claim the account as an asset. The son's portion may be protected depending on state law and the type of bankruptcy, so he should speak with a bankruptcy attorney if this is a concern.
