How Long Do You Have to Report a Forged Check?

Under the Uniform Commercial Code, you have one year from the date your bank statement is made available to report a forged check and demand your money back. That is the outside limit, and it is absolute. In practice, the deadline that decides most claims is much shorter: your deposit agreement likely requires you to flag unauthorized items within 14 to 30 days, and a separate 30-day “repeater rule” can leave you on the hook for any additional forgeries by the same person if you stay silent past that window. So the honest answer to how long you have to report a forged check is layered, and the shortest layer is the one you have to meet.

The Deadlines That Actually Matter

Three UCC deadlines run at the same time, plus whatever your bank wrote into the account contract. Trip any one of them and part or all of your claim can disappear.

Reasonable Promptness

The UCC requires you to review your statements with “reasonable promptness” and report unauthorized signatures or alterations. The code does not fix a number of days. What counts as prompt depends on how often you get statements, whether you use online banking, and how obvious the forgery was on the face of the statement. If the bank can show that your delay caused it a loss it could otherwise have avoided, you lose the right to recover that amount.¹

The 30-Day Repeater Rule

This is the deadline that catches most people. If someone forges one of your checks and you fail to report it within 30 days after the statement showing that check becomes available, you become liable for any additional forgeries by the same person that the bank pays before you finally speak up. The bank paid the first one in good faith, and once it put a statement in your hands, the clock started.¹

The repeater rule matters most when the forger has ongoing access, such as an employee or bookkeeper writing unauthorized checks over months. Catching the first one early caps your exposure. Letting it slide means every later check from that same person is yours to eat.

The One-Year Absolute Cutoff

Regardless of anyone’s fault, you have one year from the date your bank statement is made available to discover and report an unauthorized signature or alteration. After that year, your claim is barred. No exceptions, no extensions, and this applies even if the bank was itself negligent in paying the forged check.¹

Your Deposit Agreement Can Shorten All of This

Here is the catch most account holders miss. The UCC lets banks tighten these timeframes by contract, and most do. Deposit agreements commonly require customers to report discrepancies within 14 to 30 days of the statement being made available. If your agreement says 30 days and you report on day 45, the bank can deny your claim even though the one-year UCC cap has not run. What the agreement cannot do is release the bank from responsibility for its own lack of good faith or failure to exercise ordinary care.

Before you do anything else, pull your deposit agreement and read the section on statement review, unauthorized transactions, or dispute resolution. If you no longer have a copy, request one or look in your online banking portal. Your contractual deadline is the number that will most likely decide your claim.

What Happens If You Miss Each Deadline

The consequences stack, and they get worse the longer you wait.

Miss the “reasonable promptness” standard or the shorter window in your deposit agreement, and the bank can deny reimbursement for any loss it can trace to your delay. Miss the 30-day repeater deadline, and every subsequent forgery by the same person becomes your loss, not the bank’s. Miss the one-year absolute deadline, and the claim is gone entirely.¹

Late reporting is not always all-or-nothing. Under UCC 4-406(e), if the bank was also negligent in paying the item, the loss is split between you and the bank based on how much each side’s carelessness contributed. So even a late report can produce partial recovery if the bank missed red flags like a signature that looked nothing like yours or an unusual payee. And if the bank did not pay the check in good faith at all, the preclusion rules do not apply and the bank bears the full loss regardless of when you reported.¹

Your own conduct before the forgery counts too. If your failure to exercise ordinary care substantially contributed to the forgery, such as leaving signed blank checks accessible, you cannot assert the forgery against someone who paid it in good faith.²

Reporting to Police Runs on a Separate Clock

A police report is not what recovers your money. Reporting to your bank is what recovers your money. A police report enables criminal prosecution of the forger, and its deadline is set by the statute of limitations, which is a different clock entirely.

For felony forgery, most states set statutes of limitations in the range of three to seven years. The general federal statute of limitations is five years from the date of the offense.³ When the fraud affects a financial institution, that window extends to ten years, and federal bank fraud under 18 U.S.C. § 1344 falls inside that extended period.⁴

Even though you have years to file with police, waiting hurts you. Evidence gets stale, witnesses forget, and surveillance footage gets overwritten. A prompt police report also strengthens your bank claim by showing you treated the matter seriously from the start.

How to Report Before the Clock Runs Out

Call your bank’s fraud department the moment you spot the forged item. Phone first to get the investigation started, then follow up in writing so there is a dated record. The bank will ask you to complete an affidavit of forgery, a sworn statement that you did not authorize the check. Expect to provide your account number, the check number, the dollar amount, the date the check was paid, and the payee name. Ask for a copy of the front and back of the forged check if you do not have one already.⁵

Many banks issue provisional credit while they investigate. If multiple checks were forged or your checkbook was stolen, ask about closing the compromised account and opening a new one.⁶

After the bank, file with your local police. Bring the affidavit, copies of the forged check, and the statement showing the transaction. Give the resulting case number to your bank; it serves as evidence that a crime was reported and supports your claim.⁶

What matters for the deadline is the date you notified the bank, not the date the investigation finishes. Notify first, complete the paperwork after.

If Your Bank Denies the Claim

Banks do deny forgery claims, and late reporting is one of the most common reasons cited. If you believe the denial is wrong, ask for it in writing with a specific explanation of the reasoning. If the bank invokes a shortened reporting period from your deposit agreement, compare the agreement language with what actually happened, and remember that the bank still cannot use the agreement to escape liability for its own failure to exercise ordinary care.

If you cannot resolve it directly, file a complaint with the Consumer Financial Protection Bureau. The CFPB accepts complaints about checking and savings accounts. Describe the problem with key dates and amounts, attach supporting documents up to 50 pages, and identify the company. The CFPB forwards the complaint to the bank, which generally responds within 15 days, with up to 60 days allowed for complex cases. You then have 60 days to give feedback on the response.⁷

The CFPB does not order banks to pay, but complaints become part of a public database and can trigger regulatory attention, which is why banks tend to take them seriously. For larger amounts, small claims court or civil litigation are available depending on the dollar amount and your jurisdiction.
