If a bank accidentally deposited money into your account and you spent it, the bank can still take the full amount back, drive your balance negative, sue you for whatever it can’t recover, and in serious cases refer the matter for criminal prosecution. The deposit never became your money, and spending it does not change that. What determines how bad things get is how much you spent, whether you tried to report the error, and how quickly you act now.
The Money Was Never Yours
A deposit made in error does not transfer ownership to you, no matter how long it sits in your account. The legal principle is unjust enrichment: you cannot keep a windfall that reached you only through someone else’s mistake. Courts treat it the way they would treat a cashier handing you an extra $100 bill by accident. You received something you were not entitled to, and the law imposes a duty to return it.
Both the Office of the Comptroller of the Currency and the Consumer Financial Protection Bureau confirm that banks can remove mistakenly deposited funds without your permission and send them to the correct account.1HelpWithMyBank.gov.

The Reversal Happens Even if Your Balance Goes Negative
This is where it gets painful. The bank will pull back the full amount of the erroneous deposit, even if doing so drives your account below zero. Receive $5,000 by mistake, spend $3,000, and the bank still takes $5,000 back. Your account drops $3,000 below your actual balance.
A negative balance can trigger overdraft fees, returned-payment fees on checks and automatic payments that bounce, and eventually account closure if the deficit is not resolved. No federal regulation requires the bank to waive those fees when the overdraft resulted from fixing its own error, though many banks will reverse them if you call and explain. The earlier you contact them, the more leverage you have.
If the bank suspects you might withdraw the funds before it completes the correction, it can freeze your account. The freeze is limited to the amount of the erroneous deposit, not your entire balance.3HelpWithMyBank.gov. Can the Bank Freeze My Account if They Made an Error? Your legitimately deposited money should remain accessible.
If You Can’t Repay, the Bank Can Sue
When a straight reversal cannot recover the money because you have already spent it, the bank’s next step is a civil lawsuit. The usual legal theories are unjust enrichment (you received a benefit you were not entitled to) and conversion (you treated someone else’s property as your own). Neither requires the bank to prove you meant to steal. It only has to show it made an error, you received the funds, and you have not returned them.
If the bank wins a judgment, it gains access to several collection tools:
- Wage garnishment. Under federal law, a judgment creditor can garnish up to 25% of your disposable earnings per pay period, or the amount by which your weekly earnings exceed 30 times the federal minimum wage, whichever produces the smaller garnishment. Some states cap it lower.4Office of the Law Revision Counsel. 15 USC 1673 – Restriction on Garnishment
- Bank account levy. The bank or its attorneys can get a court order directing another financial institution to hand over funds in your accounts up to the judgment amount. Federal benefits like Social Security and veterans’ payments are generally exempt, and banks are required to protect two months of those direct deposits automatically.
- Property liens. In some jurisdictions, a judgment creditor can place a lien on real property you own, which has to be satisfied before you can sell or refinance.
You will likely owe the bank’s attorney fees and court costs on top of the original amount, depending on your state’s rules and any fee-shifting language in your account agreement.
What Happens to Your Credit
Civil judgments themselves no longer appear on credit reports. The three major credit bureaus stopped including them in 2017. Your credit does not necessarily escape, though. If you do not pay, the bank may send the debt to a third-party collection agency, and that collection account will appear on your credit report. Negative items like collection accounts can stay on your report for up to seven years.5Consumer Financial Protection Bureau. A Summary of Your Rights Under the Fair Credit Reporting Act
Criminal Charges Are a Real Possibility
Spending money you know is not yours can turn a civil dispute into a criminal case. Prosecutors typically charge theft, larceny, or receiving stolen property. The label varies by state, but the concept is the same. The critical element is intent: did you know the deposit was a mistake, and did you spend it anyway? Checking your account, seeing an unexplained $10,000, and immediately buying a car with it looks very different from gradually spending a small overage you genuinely did not notice.
One widely reported case shows how fast this can escalate. In 2019, a Pennsylvania couple saw roughly $120,000 land in their account due to a bank error. Rather than reporting it, they went on a spending spree, buying an SUV, a camper, and other items. When the bank reversed the deposit and their balance went deeply negative, they were arrested and charged with felony theft, receiving stolen property, and conspiracy.
The severity of charges generally tracks the dollar amount. Spending a few hundred dollars might result in a misdemeanor carrying fines, probation, or up to a year in jail. Larger sums push the charges into felony territory, where prison sentences of several years become possible. A felony conviction brings lasting collateral consequences: difficulty finding employment, loss of professional licenses, and in some states, restrictions on voting rights.
You Can’t Wait the Bank Out
Hoping the bank forgets is one of the worst strategies available. Statutes of limitation for unjust enrichment and similar civil claims typically run from two to six years depending on the state, and the clock often does not start until the bank discovers the error, not from the date of the deposit. Criminal statutes of limitation vary as well, and for felony-level theft, many states allow prosecution for five years or more.
What to Do Right Now
If you have not spent the money, the smartest move is also the simplest: do not touch it. Even transferring it to a savings account to set it aside can cause problems if the bank attempts an automated reversal from your checking account and finds the funds missing. Leave it exactly where it landed.
Contact the bank immediately. Tell them the amount, the date it appeared, and that you believe it is an error. Get the name of every person you speak with, note the date and time, and follow up in writing through email or the bank’s secure messaging portal. If the bank is slow to act, file a written dispute referencing the specific transaction.
That paper trail is your protection. If a dispute arises later about whether you tried to return the money, documented good-faith efforts to report the error will insulate you from both civil liability and criminal exposure. Courts and prosecutors distinguish sharply between someone who spent the money and hoped nobody would notice, and someone who flagged the problem and cooperated from day one.
If you have already spent some or all of the funds, contact the bank anyway and start arranging repayment. Offer a payment plan if you cannot repay in full. The longer you wait, the worse it looks, and the more likely the bank is to escalate from a phone call to a courtroom, or from a courtroom to a prosecutor’s office.
