If a check is stolen and cashed, the bank that paid it is almost always responsible for putting the money back in your account. The Uniform Commercial Code lets a bank charge your account only for checks you actually authorized, so a forged or stolen check is the bank’s problem to absorb, not yours.1Cornell Law School. Uniform Commercial Code 4-401 – When Bank May Charge Customer’s Account That default flips in a handful of specific situations, and it also disappears entirely if you miss certain deadlines. Which exception applies, and how fast you act, decides where the loss really lands.
The Default Rule: Your Bank Owes You the Money
Every checking account runs on one promise: the bank pays out of your account only when you tell it to. The UCC captures this by saying a bank may charge your account only for items that are “properly payable.”1Cornell Law School. Uniform Commercial Code 4-401 – When Bank May Charge Customer’s Account A check you never signed, or one someone altered after you wrote it, is not properly payable. The bank has to credit you back.
This isn’t a negligence test. The bank doesn’t escape liability by showing it looked carefully and the forgery was a good one. If the item wasn’t authorized and the bank paid it, the bank owes you the money.
When Your Signature Was Forged
If a thief grabbed a blank check or printed up a counterfeit and signed your name as the account holder, the loss sits with your bank. A forged signature has no legal effect under the UCC; it operates as the forger’s own signature, not yours.2Cornell Law School. Uniform Commercial Code 3-403 – Unauthorized Signature You never authorized the check, so it was never properly payable, and the bank cannot keep the money charged to your account.
The reason tracks the facts: your bank has your signature on file and is in the best position to spot a fake. When it misses one, it pays. Your bank may then try to recover from the bank that first accepted the check, but that’s a dispute between the banks.
When the Payee’s Endorsement Was Forged
A different situation: you wrote a real check to someone, a thief intercepted it, forged the payee’s signature on the back, and cashed it. Here your signature is genuine. The fraud is in the endorsement, and liability lands on the depositary bank, the first bank that took the check from the forger.
Every bank that presents a check makes warranties to the paying bank, including a warranty that it is entitled to collect on the item.3Cornell Law School. Uniform Commercial Code 4-208 – Presentment Warranties A forged endorsement breaks that warranty, so your bank can push the loss back to the bank that took the check in person and had the chance to check ID.
The intended payee has their own claim. Paying a check that bears a forged endorsement counts as conversion under the UCC, which means the person who should have received the money can sue the bank that cashed it directly.4Cornell Law School. Uniform Commercial Code 3-420 – Conversion of Instrument
When the Loss Shifts to You
The default rule has exceptions, and some are harsh. You can end up eating the loss in three main scenarios.
You Were Tricked Into Writing the Check
Someone impersonates a contractor, a landlord, or a business contact. You write a check to the name they gave you, believing they’re the real person. The scammer endorses it in that name and deposits it. Under the UCC’s impostor rule, that endorsement counts as valid, and the loss sits with you.5Cornell Law School. Uniform Commercial Code 3-404 – Impostors; Fictitious Payees The bank paid exactly the check you handed over, to the person you handed it to. The same rule covers fictitious-payee schemes where someone creates checks payable to people who don’t exist. The one opening: if the bank that cashed the check ignored obvious red flags, the loss can be split based on each party’s share of fault.
An Employee Did It
If an employee entrusted with handling checks forges an endorsement, the employer bears the loss, not the bank.6Cornell Law School. Uniform Commercial Code 3-405 – Employer’s Responsibility for Fraudulent Indorsement by Employee “Entrusted” is read broadly. It includes independent contractors and reaches anyone who processes invoices, prepares outgoing checks, or supplies payee information, not only people with signing authority. The only workers excluded are those whose contact with checks is limited to transporting or storing blanks. Here too, if the bank that cashed the check failed to use reasonable care, the employer can recover a portion based on comparative fault.
You Were Careless and It Contributed to the Fraud
Even in a case the bank would normally own, your own carelessness can flip the result. If your failure to use ordinary care substantially contributed to the forgery, you lose the right to make the bank pay.7Cornell Law School. Uniform Commercial Code 3-406 – Negligence Contributing to Forged Signature or Alteration of Instrument Courts have treated these as examples:
- Pre-signing blank checks and handing them off.
- Leaving large gaps on the payee or amount line so a check can be altered from $50 to $5,000.
- Storing checks in unsecured places, like an unlocked car or a shared desk drawer.
The bank has to prove both the carelessness and that it substantially contributed to the fraud. If it does, but you can show the bank was also careless in paying the check, the loss gets divided based on how much each side’s negligence contributed.7Cornell Law School. Uniform Commercial Code 3-406 – Negligence Contributing to Forged Signature or Alteration of Instrument
The Deadlines That Can Erase Your Claim
Even a textbook forgery can become your loss if you sit on it. The UCC gives you specific duties around reviewing statements, and missing them can wipe out an otherwise valid claim.
You have to review your statements with reasonable promptness after the bank makes them available, and report an unauthorized check promptly once you spot it or should have spotted it.8Cornell Law School. Uniform Commercial Code 4-406 – Customer’s Duty to Discover and Report Unauthorized Signature or Alteration What counts as prompt depends on the situation, but the consequences of delay are concrete.
If the same forger cashes a series of checks, the bank can cut off your claims for every check it paid after you had a reasonable chance to review the first statement and didn’t. The UCC caps that review window at 30 days.8Cornell Law School. Uniform Commercial Code 4-406 – Customer’s Duty to Discover and Report Unauthorized Signature or Alteration A thief who hits you in January and again in March can stick you with the March losses if you didn’t flag January within 30 days of the statement.
The hardest cutoff is absolute. If you don’t discover and report a forged check within one year of receiving the statement showing it, you cannot recover from the bank at all, no matter how careful you were or how careless the bank was.8Cornell Law School. Uniform Commercial Code 4-406 – Customer’s Duty to Discover and Report Unauthorized Signature or Alteration A year sounds long until you notice you never opened last January’s statement.
What to Do the Day You Spot It
Speed matters because the deadlines run from when the statement is available, not when you open it. Call your bank’s fraud department the same day you see the problem.
The bank will have you sign a sworn statement, often called a Declaration of Unauthorized Endorsement or an Affidavit of Forgery, confirming the check was fraudulent. Some banks require notarization, which runs roughly $5 to $10 at banks or UPS stores and varies by state. File a police report too. It won’t get your money back on its own, but banks treat it as supporting evidence and it creates a paper trail.
Once you submit the paperwork, the bank investigates. For claims involving substitute checks (the electronic images processed under Check 21), federal rules require provisional credit of up to $2,500 within 10 business days if the investigation is still open, with any remainder credited within 45 calendar days.9eCFR. 12 CFR 229.54 – Expedited Recredit for Consumers For other check-fraud claims, no federal regulation sets a specific timeline, so resolution depends on the bank’s internal process and how complicated the facts are. Straightforward forgeries can resolve in a few weeks. Contested claims can run past 90 days. When the investigation closes in your favor, you get a permanent credit.
Mobile Deposit and Why Day One Matters
Mobile deposit changed the pace of this problem. A thief who intercepts a check can deposit it through an app and pull out the funds before anyone notices, and in some cases the original paper check still gets deposited later at a different bank. Federal regulations provide indemnity protections for banks that accept the paper original when the loss stems from the check already having been paid through a mobile deposit.9eCFR. 12 CFR 229.54 – Expedited Recredit for Consumers The underlying liability still runs through the UCC framework: a forged endorsement means the depositary bank bears the loss. The money just moves faster than detection often does.
If you write checks regularly, drop them at a post office rather than a residential mailbox, use gel-ink pens (harder to chemically wash), and check your account daily instead of waiting for the monthly statement. Catching the fraud on day one is worth more than any rule about who’s responsible on day thirty.
