If a bank accidentally deposited money into your account and you spent it, the bank can still claw back every cent, and you are on the hook for the shortfall. Depending on how much you spent and whether you tried to return it, you could face overdraft fees, a civil lawsuit, wage garnishment, damaged credit through collections, and in serious cases, criminal theft charges.
The Money Was Never Yours
A deposit made in error does not become your property just because it landed in your account. The legal principle is unjust enrichment: you cannot keep a windfall that reached you through someone else’s mistake. Courts treat it the same as a cashier handing you an extra hundred-dollar bill by accident. You received something you were not entitled to, and the law imposes a duty to give it back.
Both the Office of the Comptroller of the Currency and the Consumer Financial Protection Bureau confirm that a bank can remove mistakenly deposited funds without your permission.1HelpWithMyBank.gov.

If it suspects you might withdraw the funds before it completes the correction, it can also freeze your account up to the amount of the erroneous deposit, though your own money should remain accessible.3HelpWithMyBank.gov.

What the Reversal Does to Your Balance
If the money is gone, the bank still reverses the full amount. Spent $3,000 of a mistaken $5,000 deposit? The bank pulls back the whole $5,000, and your account drops $3,000 below your real balance.
A negative balance sets off a chain reaction. Overdraft fees. Returned-payment fees on any checks or automatic debits that bounce. Eventually, if the deficit is not resolved, account closure. No federal rule forces the bank to waive these fees just because its own error caused the overdraft, though many banks will reverse them if you call quickly and explain what happened. Speed is your leverage.
Civil Lawsuits and How the Bank Collects
When a straightforward reversal cannot recover the money, the bank’s next step is civil litigation. The common legal theories are unjust enrichment and conversion, meaning you treated someone else’s property as your own. Neither requires the bank to prove you meant to steal anything. It only has to show it made an error, you received the funds, and you have not returned them.
A judgment opens the door 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. A court order can direct 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 must automatically protect two months’ worth of those direct deposits.
- 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 About Your Credit?
Civil judgments themselves no longer appear on credit reports; the three major bureaus stopped including them in 2017. Your credit still takes a hit indirectly. If you do not pay, the bank can hand the debt to a third-party collection agency, and that collection account will show up on your report. Negative items like collections can stay there for up to seven years.5Consumer Financial Protection Bureau.

When It Becomes a Criminal Case
Spending money you know is not yours can push a civil dispute into criminal territory. Prosecutors typically charge theft, larceny, or receiving stolen property. The label varies by state; the idea does not. The pivotal element is intent. Did you know the deposit was a mistake and spend it anyway? Seeing an unexplained $10,000 land in your account and immediately buying a car with it reads very differently than gradually spending a small overage you did not notice.
A 2019 Pennsylvania case shows how fast this can escalate. A couple saw roughly $120,000 land in their account due to a bank error. Instead of reporting it, they bought an SUV, a camper, and other items. When the bank reversed the deposit and their balance cratered, they were arrested and charged with felony theft, receiving stolen property, and conspiracy.
Charges generally track the dollar amount. A few hundred dollars might be a misdemeanor carrying fines, probation, or up to a year in jail. Larger sums push into felony territory, where prison sentences of several years are possible. A felony conviction brings lasting collateral consequences: trouble finding work, loss of professional licenses, and in some states restrictions on voting.
Waiting It Out Doesn’t Work
Do not count on the bank forgetting. Statutes of limitation for unjust enrichment and similar civil claims typically range from two to six years depending on the state, and the clock often does not start until the bank discovers the error, not the date of the deposit. Criminal statutes of limitation vary too, and for felony-level theft many states allow prosecution for five years or more. Time is not on your side.
What to Do Right Now
If the money is still in your account, do not touch it. Even moving it to savings to “set it aside” can cause problems when the bank tries an automated reversal from checking and finds the funds gone. Leave it where it is.
Contact your bank immediately. Give them the amount, the date it appeared, and your belief that it is an error. Note the name of every person you speak with, the date, and the time. Follow up in writing through email or the bank’s secure messaging portal so there is a paper trail. If the bank is slow, file a written dispute referencing the specific transaction.
That paper trail is your protection. If anyone later questions whether you tried to return the money, documented good-faith efforts insulate you from both civil liability and criminal exposure. Courts and prosecutors draw a sharp line between the person who spent the money hoping nobody would notice and the person who reported the problem on day one.
If you have already spent some or all of the money before realizing what happened, call the bank anyway and start arranging repayment. Ask about a repayment plan, ask about fee waivers, and put every agreement in writing. The longer you wait, the worse it looks, and the more likely the bank moves from a phone call to a lawsuit.
