You cannot check another person's bank account balance without their permission

A bank will not show you another person's account balance, transaction history, or account details unless you are an authorized user on that account or you have legal authority to access it. This is protected by federal law — the Gramm-Leach-Bliley Act requires banks to keep customer financial information private. Even spouses, parents, and adult children cannot see each other's accounts without explicit permission from the account holder.

The only exceptions are narrow: a court order, power of attorney, guardianship, or being listed as an authorized user or joint account holder. If you need to know someone's balance for a legitimate reason — managing their finances, collecting a debt, or verifying income — there are legal ways to do it, but they all require the account holder's cooperation or a court process.

Key Takeaways

  • Banks will not disclose account information to anyone except the account holder, authorized users, or someone with a court order or power of attorney.
  • If you are a joint account holder or authorized user, you can check the balance through online banking, the bank's app, or by calling the bank with the account number.
  • If you have power of attorney or guardianship, bring the legal document to the bank in person; they will verify it before granting access.
  • If you need to verify someone's income or assets for a loan, court case, or debt collection, you must ask them directly or go through a formal legal process.
  • Attempting to access someone's account without permission is fraud and can result in criminal charges.

Checking a balance when you are an authorized user or joint account holder

If the account holder has added you as an authorized user or joint account holder, you have the right to check the balance. The method depends on how the account is set up and what the bank offers.

Log into online banking using your own credentials if you have been set up with access. Most banks allow authorized users and joint holders to see the full account balance, recent transactions, and account details through their website or mobile app. If you do not have online access yet, call the bank's customer service line with the account number and your name; they will verify your identity and either give you the balance over the phone or help you set up online access.

Visit the bank branch in person with a photo ID if you prefer not to use online banking. A teller can look up the account and tell you the current balance. Some banks also allow you to check balances at ATMs if you have a debit card linked to the account.

Accessing an account with power of attorney or guardianship

If you hold a legal document giving you authority over someone else's finances — a power of attorney, healthcare proxy, or guardianship order — you can access their bank account, but you must prove it to the bank first.

Bring the original or certified copy of the legal document to the bank branch. The bank's legal or compliance department will review it to confirm it is valid and that it grants you the authority you claim. This process can take a few days to a few weeks, depending on the bank and the complexity of the document. Once verified, the bank will give you access to the account — usually through online banking, a debit card, or the ability to make transactions on the account holder's behalf.

If the account holder is deceased, the process is different. You will need to provide a death certificate and proof that you are the executor of the estate or the next of kin. The bank will freeze the account until the estate is settled, and access is limited to the executor or administrator.

Verifying income or assets for a loan or legal case

If you need to confirm someone's bank balance for a mortgage application, loan underwriting, court case, or debt collection, you cannot access their account directly. Instead, you must ask them to provide the information themselves.

For a loan, the applicant provides bank statements directly to the lender. The lender may also order a verification of deposits (VOD) from the bank, which is a formal request the bank can fulfill without the account holder's permission — but only to a financial institution, employer, or government agency, not to a private person.

For a court case or debt collection, a subpoena is the legal tool. A subpoena is a court order requiring the bank to produce account records. It must be issued by an attorney, judge, or court clerk and served on the bank according to state rules. The account holder is usually notified that their records have been subpoenaed, though in some cases the subpoena can be sealed to prevent that notification.

What happens if you try to access someone's account without permission

Accessing someone's bank account without their permission or legal authority is fraud and identity theft. It is a federal crime under the Computer Fraud and Abuse Act and state identity theft laws. Penalties include fines up to $250,000 and prison time of up to 15 years, depending on the amount of money involved and whether the person caused financial harm.

Banks also monitor for suspicious access patterns. If you log into an account from an unusual location, device, or time, the bank may flag it and contact the account holder. If the account holder reports unauthorized access, the bank will investigate and may freeze the account. Law enforcement can subpoena the bank's security logs and IP address records to identify who accessed the account.

If you suspect someone has accessed your account without permission, contact your bank immediately. Report the unauthorized access, ask the bank to review the login history, and consider changing your password and enabling two-factor authentication.

Asking someone directly for their balance or bank statements

The simplest and legal way to know someone's bank balance is to ask them. If you have a legitimate reason — you are managing their finances, you are a creditor, or you are helping them with financial planning — explain why you need the information and ask them to share it with you.

They can provide a screenshot of their online banking, a recent bank statement, or a letter from the bank confirming the balance. If they are reluctant to share, you can ask them to provide the information to a third party you both trust — an accountant, lawyer, or financial advisor — who can then confirm it to you without violating their privacy.

If you are a creditor trying to collect a debt, you can ask for bank statements as part of a settlement negotiation or as part of a post-judgment discovery process. If they refuse and you have a court judgment against them, you can use a debtor's examination or interrogatory to compel them to disclose their assets, including bank balances.

Frequently Asked Questions

Can a parent check their adult child's bank account?

No, not without permission. Once a child turns 18, their bank account is private. A parent can only access it if they are listed as a joint account holder or authorized user, or if they have power of attorney. If the child is incapacitated or missing, a parent can petition the court for guardianship or conservatorship, which grants legal access to financial accounts.

Can a spouse check the other spouse's bank account?

No, unless they are a joint account holder or authorized user. Marriage does not grant automatic access to a spouse's separate accounts. If you need to know your spouse's balance for divorce proceedings or financial planning, you can ask them directly or, if they refuse, request it through a court order called a subpoena or interrogatory as part of the divorce discovery process.

Can an employer check an employee's bank account?

No. An employer cannot access an employee's personal bank account without a court order. If an employer needs to verify income or assets for a loan they are offering, the employee must provide the information voluntarily. If the employer suspects wage theft or fraud, they can report it to law enforcement, which can then obtain a subpoena.

What if I need to check a balance for a debt collection case?

You cannot check the balance yourself. If you have a court judgment against someone, you can use a debtor's examination (also called a debtor's interrogatory or post-judgment discovery) to force them to disclose their assets. You file a motion with the court, and the debtor is ordered to answer questions about their bank accounts, income, and property. If they refuse, they can be held in contempt of court.

Can a bank tell me if someone has an account there?

No. Banks do not confirm or deny whether a specific person has an account, even if you say you are a family member or creditor. This is part of their privacy policy. If you need to know whether someone has an account at a particular bank, you must ask them directly or obtain a subpoena.
