The Fake Check Scam: When the Buyer Overpays

the overpayment is the scam

The fake check map

The buyer sends a check for too much, the parent deposits it, sees the money appear, and sends the difference back. Days later the check bounces. One rule stops the whole family of scams.

1. How it worksThe overpayment is the trapThe check looks real and banks must make deposited funds available quickly, so the parent sees a real balance. The polite over-explained story makes it feel safe; the money-back request is the scam.
2. The one ruleNever send money back to a buyerAny overpayment ends the deal: no refund, no wire, no gift cards. The item stays for sale. Cash or an in-person verified payment only, at a bank or a police-station exchange point.
3. Online salesStay on the platformUse the platform's own payment system and ignore messages that move the conversation to email or text, where the scam can operate without the platform's protections.
4. If money already movedReport it fastContact the bank, the payment channel, and reportfraud.ftc.gov: money sent by wire or gift card may still be recoverable if reported quickly. Tell the parent the rule before listing the car, furniture, or estate items.

How the scam works

The buyer agrees to the asking price, then sends a check for too much. The excuse varies: shipping costs, movers, a travel refund, a mistaken amount. The parent deposits the check, sees the money appear, and sends the difference by wire or gift card. Days later the check is discovered to be fake, the deposit is reversed, and the parent is out the money they sent. The bank is not at fault and will not cover the loss: the parent paid a stranger on the strength of a fake check.

Why it works

Two facts make it convincing. First, the check looks real, and banks are required to make deposited funds available quickly, so the parent sees a real balance. Second, the story is polite and bureaucratic, the kind of over-explained message a legitimate buyer might send. The scam does not ask the parent to send the item first, which feels safer. The money-back request is the trap.

The one rule that stops it

1. Any overpayment ends the deal. The parent does not refund, does not wire, does not buy gift cards. The item stays for sale.
2. Cash or an in-person, verified payment only. For a car or furniture sale, meet in person at the bank or a police-station exchange point and complete the payment there.
3. For online sales, use the platform's own payment system and ignore messages that move the conversation to email or text.
4. If a check was already deposited and the parent sent money back, report it fast: the issuer, the bank, and ReportFraud.ftc.gov. Money sent by wire or gift card may still be recoverable if reported quickly.

Where parents meet this scam

Selling the parents' car, furniture, or belongings is exactly when this scam appears: selling the parent's car, estate sales, and online marketplace listings. Tell the parent the rule before they list anything.
