Disputing a Charge: Credit vs Debit

Two cards, one fraudulent charge, two completely different sets of legal rights. This is the most consequential distinction in consumer finance that almost nobody is taught.

Two laws, two very different deals

A credit card and a debit card look identical and behave identically at the till. Legally they are not remotely the same product.

Credit cards fall under the Fair Credit Billing Act, implemented as Regulation Z. You dispute a billing error in writing within 60 days of the statement on which it first appeared. The creditor must resolve it within two complete billing cycles and in no case later than 90 days, and crucially, it cannot try to collect the disputed amount while the investigation runs.

Debit cards fall under the Electronic Fund Transfer Act, implemented as Regulation E. The key difference is that the money has already left your account, so you're waiting to get it back rather than withholding payment.

The debit clock, and why speed matters

Regulation E sets a tiered liability cap for unauthorized transfers, and the tier depends on how fast you report.

Report within two business days of learning your card or credentials were lost or stolen, and your liability is capped at $50. Report after two business days, and it can rise to $500. And an unauthorized transfer that appears on a statement must be reported within 60 days of the statement being sent to avoid liability for subsequent transfers.

One protection worth knowing: your own negligence cannot be used to impose greater liability than Regulation E allows. Writing your PIN on the card doesn't void your rights.

What this means in practice

Many banks voluntarily offer zero-liability policies that are more generous than the law requires. That's a policy, not a right — policies can carry conditions and can change.

The legal floor is what you can rely on, and on that floor credit cards are meaningfully safer for anything with elevated fraud risk: online purchases from unfamiliar merchants, travel, deposits, subscriptions.

This is educational information about consumer protection law, not advice about which card to carry. The rules themselves are the thing worth knowing.
