Several people and institutions can legally access your bank account without your permission: joint owners and agents you already authorized, the bank itself under a right of set-off, private creditors who have won a court judgment against you, the IRS and state tax authorities, federal agencies collecting child support or student loans, law enforcement during an investigation, and heirs or executors after your death. Each has different powers and different limits, and knowing which is which is what lets you push back when funds disappear or get frozen.
People You Already Authorized
The most common way someone reaches your account without asking is that you signed a document, sometimes years ago, giving them the right.
Joint Account Owners
A co-owner on a joint checking or savings account generally has the same authority you do. Either owner can withdraw funds, transfer money, or close the account without the other person’s consent, regardless of who deposited the money.1Consumer Financial Protection Bureau. A Joint Checking Account Owner Took All the Money Out Your account agreement and state law may add some protection, but the default rule is full access for either owner.
Power of Attorney Agents
An agent under a power of attorney can access your bank accounts and transact on your behalf. A general POA typically allows the agent to withdraw funds, write checks, open and close accounts, and manage deposits, while a limited POA restricts the agent to specific accounts or transactions. A durable power of attorney stays in effect if you become mentally incapacitated; a non-durable one ends at that point.
Court-Appointed Guardians and Conservators
When a court finds that a person can’t manage their own finances, a judge may appoint a guardian or conservator with legal authority to manage the ward’s accounts, pay bills, and make financial decisions.2Consumer Financial Protection Bureau. Managing Someone Else’s Money – Help for Court-Appointed Guardians of Property and Conservators The court order sets the limits, the guardian has to keep the ward’s money separate from their own, and many courts cap withdrawals without prior approval and require annual accountings.
Your Own Bank
Your bank can take money from your account to cover a debt you owe that same bank, with no court order and often no advance notice. This right of set-off is written into the account agreement you signed at opening.3Legal Information Institute. Uniform Commercial Code 9-340 – Effectiveness of Right of Recoupment or Set-Off Against Deposit Account If you fall behind on a credit card, personal loan, or other obligation at the institution that also holds your checking or savings, it can move funds from your deposit account to cover the past-due balance, plus accrued interest and fees.
You may not see it coming. One day the balance is simply lower. Social Security and certain other federal benefits deposited by direct deposit are generally protected from set-off, and you should tell your bank when your account holds them.4HelpWithMyBank.gov. Can My Bank Take Social Security Money to Pay on a Loan? Keeping your loans at a different institution from your deposit accounts is one practical way to limit exposure.
Private Creditors With a Court Judgment
A credit card company, medical provider, or landlord cannot reach into your account on its own. The creditor has to sue you in civil court, win a money judgment, and ask the court to issue a garnishment or levy order to your bank. When the bank receives that order, it freezes the specified amount right away. Banks typically charge a processing fee, often $75 to $125, deducted directly from your account on top of what was garnished.
How Much a Creditor Can Take
For ordinary consumer debts, federal law caps garnishment at the lesser of 25% of your disposable earnings or the amount by which your weekly disposable earnings exceed 30 times the federal minimum wage. At the current $7.25 minimum, that threshold is $217.50 per week; if your weekly disposable earnings fall at or below $217.50, no garnishment is allowed at all.5U.S. Department of Labor. Fact Sheet 30 – Wage Garnishment Protections of the Consumer Credit Protection Act State law may protect more, and where the two conflict the more protective rule wins.
Federal Benefits Are Shielded
Certain deposits are automatically protected from creditor garnishment. When your bank receives a garnishment order, it must review the account for direct deposits from protected federal programs and keep at least two months’ worth of those benefit payments available to you.6eCFR. 31 CFR Part 212 – Garnishment of Accounts Containing Federal Benefit Payments Protected income includes:
- Social Security and SSI benefits
- Veterans benefits
- Civil service and federal employee retirement benefits
- Railroad retirement and unemployment insurance benefits
- Federal student aid
- FEMA disaster assistance
If the account holds more than two months’ worth of these deposits, the excess can be garnished. If you receive $1,000 a month in Social Security and your balance is $3,000, the bank can release up to $1,000 to a creditor while keeping $2,000 protected.7Consumer Financial Protection Bureau. Can a Debt Collector Take My Federal Benefits, Like Social Security or VA Payments? The automatic protection depends on direct deposit; if you deposit benefit checks manually, the bank may not recognize the funds as protected.
The IRS and State Tax Agencies
Tax authorities have broader powers than private creditors. They do not need to sue you or get a court order. They follow an administrative process that ends with a Notice of Levy sent to your bank.8Internal Revenue Service. What Is a Levy?
Before levying, the IRS must send a tax bill (Notice and Demand for Payment), and if you don’t pay, a Final Notice of Intent to Levy and Notice of Your Right to a Hearing at least 30 days before it seizes funds.9Taxpayer Advocate Service. Notice of Intent to Levy That notice gives you the right to a Collection Due Process hearing, which can pause the levy while your case is reviewed.
Once your bank receives the levy, it must hold the funds for 21 days before sending them to the IRS.10Internal Revenue Service. Levy That three-week window is your chance to resolve the debt, set up a payment plan, or show that the levy was issued in error. If you do nothing, the bank sends the money.
Federal Agencies Collecting Administrative Debts
Some federal debts get collected without any judge at all.
Back Child Support
The Office of Child Support Services works with state agencies and financial institutions to find accounts belonging to parents who owe back support. Under the Financial Institution Data Match program, state child support agencies exchange data with banks to identify accounts held by delinquent obligors.11Administration for Children and Families. Financial Institution Data Match Overview Once matched, a lien arises automatically when support falls past due, and the agency can order the bank to freeze or surrender the funds without going to court.
Student Loans and the Treasury Offset Program
The Treasury Offset Program intercepts federal payments such as tax refunds to repay past-due debts owed to federal and state agencies, including defaulted federal student loans, unpaid child support, and overdue non-tax obligations.12Bureau of the Fiscal Service. Treasury Offset Program – Child Support Program For defaulted federal student loans, the Department of Education can also garnish up to 15% of your disposable income through administrative wage garnishment, though you must be left with at least $217.50 per week.
Law Enforcement and Investigators
Criminal investigators and federal agencies can reach into your financial life during active investigations, with limits set by federal law.
Under the Right to Financial Privacy Act, a government agency generally cannot obtain your bank records unless it uses one of several approved methods: your written consent, an administrative subpoena, a search warrant, a judicial subpoena, or a formal written request.13Office of the Law Revision Counsel. 12 U.S. Code 3402 – Access to Financial Records by Government Authorities Prohibited; Exceptions In most cases the agency must notify you, and you typically have 10 to 14 days to challenge the request in court before the bank turns over information.
Separately, in cases involving suspected money laundering, drug trafficking, or other criminal activity, the government can seize funds through civil asset forfeiture. Law enforcement has to show probable cause that the money is connected to illegal conduct.14Office of the Law Revision Counsel. 18 U.S.C. 981 – Civil Forfeiture Unlike a debt levy, forfeiture can happen before you are charged with or convicted of a crime. You can contest the seizure in court, but the work of doing so falls on you.
One boundary worth knowing: banks also file Currency Transaction Reports for cash transactions over $10,000 and Suspicious Activity Reports for suspicious transactions of $5,000 or more, and federal law forbids the bank from telling you a SAR was filed.15Financial Crimes Enforcement Network. Notice to Customers – A CTR Reference Guide16Office of the Law Revision Counsel. 31 U.S. Code 5318 – Compliance, Exemptions, and Summons Authority That is reporting about your account, not access to it, but it is often what puts your account on an investigator’s radar in the first place.
Access After Death
Once the bank learns an account holder has died, the account is typically frozen. Automatic payments and pending transactions may still process, but new withdrawals stop until someone with legal authority steps in. Who that is depends on how the account was set up:
- A surviving joint owner keeps full access immediately, and the funds do not pass through probate.
- A payable-on-death beneficiary can claim the funds by presenting a death certificate and valid ID; POD transfers bypass probate.
- Without a joint owner or POD beneficiary, the account becomes part of the estate. An executor named in a will or an administrator appointed by the court must obtain letters testamentary or letters of administration before the bank releases funds.
- Many states offer a simplified small-estate procedure using an affidavit instead of full probate. Dollar thresholds vary but often apply to estates with personal property worth roughly $20,000 to $50,000 or less.
When Someone Accesses Your Account Illegally
When the access is theft or fraud rather than legal authority, federal law caps your liability, but only if you move fast. Under the Electronic Fund Transfer Act, your maximum liability for unauthorized electronic transactions depends on how quickly you report:17Office of the Law Revision Counsel. 15 U.S. Code 1693g – Consumer Liability
- Within 2 business days of learning your card or access information was lost or stolen: liability capped at $50.
- After 2 business days but within 60 days of receiving your bank statement: liability capped at $500.
- After 60 days: potentially the full amount of unauthorized transfers that happen after the 60-day window, with no cap.
These deadlines can be extended if you had a legitimate reason for the delay, such as hospitalization or extended travel.18eCFR. 12 CFR 205.6 – Liability of Consumer for Unauthorized Transfers State law or your bank’s own policy may protect you further. If you see an unauthorized transaction, call the bank right away, follow up in writing, and expect to complete a fraud affidavit and possibly file a police report.
