You can open a savings account for someone else, but the rules depend on their age and your relationship to them

The short answer is yes — but with important limits. If the person is a minor, you can open an account in their name as a parent, guardian, or custodian. If the person is an adult, you generally cannot open an account without their knowledge and consent, even if you have good intentions. Banks require the account holder to sign documents and verify their identity in person or online. What you can do is help an adult open an account, or manage one on their behalf if they give you legal authority to do so.

The rules exist to protect people from fraud and to meet federal banking laws. A bank cannot legally open an account in someone's name without that person's involvement, because the account holder is responsible for the account's activity and must agree to the bank's terms.

Key Takeaways

  • Parents and legal guardians can open savings accounts for minors in the child's name, and the child becomes the account owner even though an adult manages it.
  • You cannot open a savings account for an adult without their direct involvement — they must sign documents and verify their identity themselves.
  • If an adult wants you to manage their account, they can add you as an authorized user or give you power of attorney, but the account remains in their name.
  • Joint accounts allow two people to own one account together, with both names on it and both able to withdraw money.
  • If someone lacks the mental capacity to manage their own account, a court can appoint a conservator or guardian with legal authority to act on their behalf.

Opening a savings account for a minor in their name

If you are a parent, stepparent, or legal guardian, you can open a custodial savings account (also called a minor account or youth account) at most banks. The account is owned by the child, not by you. Your role is to manage the money and the account until the child reaches the age of majority — usually 18 or 21, depending on your state and the bank.

To open a custodial account, you will need to bring the child's Social Security number, proof of the child's identity (usually a birth certificate), and your own ID and proof of address. Some banks allow you to open the account online if you have the child's information, but many still require an in-person visit. The child does not need to be present, and they do not sign anything — you sign as the custodian.

Once the child reaches the age of majority, the account automatically converts to a regular account in their name. At that point, you no longer have authority over it unless the young adult adds you as an authorized user. Some banks notify both the custodian and the young adult when this happens; others do not, so it is worth asking the bank about their process when you open the account.

What you need to know about joint accounts

A joint account is different from a custodial account. Both people own the account equally, both names appear on the account, and either person can withdraw all the money without permission from the other. Joint accounts are common between spouses, between adult siblings, or between an adult child and an aging parent.

To open a joint account, both people must go to the bank together (or complete the process online together, if the bank offers that option). Both must provide ID, proof of address, and sign the account agreement. The bank will verify both people's identities before opening the account.

Joint accounts are useful when you want to share money — for example, a household account where both partners deposit paychecks. They are not the right choice if you want to set aside money for someone else's future without giving them access to it right now. For that purpose, a custodial account (for a minor) or a trust account (for an adult) is more appropriate.

Adding yourself as an authorized user on someone else's account

If an adult already has a savings account and wants you to help manage it, they can add you as an authorized user. This means you can withdraw money, deposit money, and handle day-to-day transactions — but the account remains in their name, and they remain responsible for it.

To become an authorized user, the account holder goes to the bank and requests it. They will need to provide your name, date of birth, and sometimes your Social Security number. You may need to visit the bank in person or sign a form, depending on the bank's policy. Once you are added, you will usually receive a debit card or checks in your name, and you can access the account online.

Being an authorized user is different from being a joint owner. You have access and signing authority, but you do not own the account. If the account holder dies or becomes incapacitated, your authority ends unless a court or legal document says otherwise. This is why authorized user status is often used for elderly parents who want an adult child to help pay bills, or for spouses who want to share account access.

Using power of attorney for financial management

If an adult wants you to manage their finances but does not want to add you to the account itself, they can give you power of attorney. This is a legal document that says you have the authority to act on their behalf for financial matters.

There are different types of power of attorney. A general power of attorney gives you broad authority over all financial decisions. A limited power of attorney restricts your authority to specific tasks — for example, managing only a savings account, or only paying bills. A durable power of attorney remains in effect even if the person becomes incapacitated, which is why many people use it for aging parents.

To set up power of attorney, the person must work with a lawyer or use a legal document service. The document must be signed, notarized, and sometimes filed with the court, depending on your state. Once it is in place, you can take it to the bank and show it to open access to the account. The account still belongs to the person who created the power of attorney, but you have legal authority to manage it on their behalf.

When a court appoints a conservator or guardian

If an adult cannot manage their own finances due to illness, disability, or age-related decline, a family member or other person can ask a court to appoint them as a conservator (in some states) or guardian of the estate (in others). This is a formal legal process, not something you can do on your own.

To become a conservator, you file a petition with the probate or family court in the person's county. The court will review the evidence that the person cannot manage their finances, may interview the person, and will decide whether to grant the conservatorship. If approved, you receive a court order that gives you legal authority to manage the person's money and accounts. You must file regular reports with the court showing how you spent the money.

Conservatorship is more formal and restrictive than power of attorney, because a court is involved and you must account for your actions. It is usually used when the person has significant assets, when family members disagree about who should manage the money, or when the person has no one to give power of attorney to. If the person is able to give power of attorney, that is usually simpler and faster.

Why banks will not open accounts without the account holder's consent

Federal banking laws require banks to verify the identity of the person whose name appears on the account. This is called Know Your Customer (KYC) compliance, and it is designed to prevent fraud, money laundering, and identity theft.

Because of these rules, a bank cannot open an account in someone's name without that person's direct involvement — even if you are a family member with good intentions. If you try to open an account for an adult without their knowledge, the bank will refuse. If someone opens an account in your name without your permission, that is fraud, and you can report it to the bank and to law enforcement.

The same rules explore to online banks and credit unions. No matter where you bank, the account holder must be involved in opening the account and must verify their identity.

Frequently Asked Questions

Can I open a savings account for my grandchild?

Yes, if you are the legal guardian or if the child's parent gives you permission. You will need the child's Social Security number and birth certificate. If you are not the legal guardian, ask the parent to open the account with you, or ask them to add you as an authorized user after they open it.

What happens to a custodial account when the child turns 18?

The account automatically converts to a regular account in the child's name. You lose access unless the young adult adds you as an authorized user. Some banks notify both parties; others do not. Ask your bank about their process when you open the account.

Can I open a joint account with someone who is not present?

No. Both account holders must be present (in person or online) to verify their identities and sign the account agreement. This is a federal requirement to prevent fraud.

If I am an authorized user, can I be held responsible if the account goes negative?

No. The account owner is responsible for overdrafts and fees. As an authorized user, you have access to the account, but you do not own it or bear legal responsibility for it.

What is the difference between power of attorney and being an authorized user?

Power of attorney is a legal document that gives you broad authority to act on someone's behalf for financial and legal matters. Authorized user status is limited to one specific account and does not give you authority over other finances. Power of attorney is more formal and requires a lawyer, while authorized user status is simpler and faster to set up.
