How to Dispute a Bill You Do Not Recognize
To dispute a bill you don't recognize, find the deadline, dispute it in writing, and don't pay the disputed amount while it's investigated. For a US credit card charge, you have 60 days from the statement it first appeared on to send the issuer a written dispute.
- Find the deadline: for a US credit card charge, 60 days from the statement it appeared on.
- Dispute in writing (letter, email or portal), not by phone, and keep a copy.
- Pay the parts you recognize, but not the disputed charge.
- Ask the company to show what you agreed to; push for removal if it can't.
- If you're ignored, go to your card issuer, then the CFPB or your state attorney general.
An unrecognized bill or charge should be disputed in writing, promptly, before you pay it. For credit card charges, the Fair Credit Billing Act gives you 60 days after the statement showing the charge to send a written billing-error notice; the CFPB says the issuer must acknowledge it within 30 days and resolve it within two billing cycles. Direct bills from companies have no single federal deadline, and a debt collector must validate a debt you dispute in writing within 30 days.
An envelope arrives from a company you've never heard of, or one you used once two years ago, for charges that match nothing you bought. First thought: scam. Second thought: what if it's real and goes to collections? The same first step handles both possibilities: a written dispute, on time. After that, you find out which it was.
How long do you have to dispute a charge?
The deadline depends on where the charge showed up. If it is on your credit card statement, the federal Fair Credit Billing Act gives you 60 days from the statement containing the error to dispute it in writing with the card issuer. If it is a direct bill or invoice from a company, there is no federal 60-day clock — the window is whatever the company's own policy and your state's consumer law say, so look at the bill for a "billing rights" or "dispute" section, check the company policy online, and dispute promptly either way. Waiting is what turns "I do not owe this" into "I do, actually, because I waited."
Do you have to dispute a charge in writing?
For credit card billing errors, yes: the CFPB says you should call the card company right away and also send a written dispute to protect your rights. For other bills, a phone call may not create a record the company has to act on. Use a letter, email or portal submission you can keep a copy of, sent to the address listed for billing inquiries rather than the payment address. Keep it short: 'I am disputing the charge of [amount] on the statement dated [date]. I have no record of authorizing or receiving this service. Please provide documentation showing the basis for this charge.'
Should you pay a bill you're disputing?
You can pay the rest of the bill (the parts you do recognize) — just not the disputed line. If the charge is on your credit card, the Fair Credit Billing Act does the heavy lifting: the issuer cannot collect the disputed amount or report it as delinquent while the dispute is open, must acknowledge your dispute within 30 days, and must resolve it within two billing cycles (no more than 90 days). For a direct bill, there is no equivalent federal clock — but if the account gets handed to a debt collector, the FDCPA kicks in: you have 30 days from the collector's first written notice to demand validation of the debt in writing, and the collector must pause collection until it provides it. Many states add their own protections on top; check your state attorney general's consumer pages.
What happens if the company can't prove the charge?
When you dispute and ask for documentation, you're asking the company to show what you agreed to or received. On a credit card dispute, the issuer must investigate and correct billing errors; if it decides the charge is valid, it must explain why in writing. With a direct biller there's no federal rule forcing removal, but a company that can't produce an agreement, service record or delivery confirmation has a weak claim, and a collector that can't validate a debt must stop collecting until it does. Many mistaken charges end at this stage. If the charge is a medical one, reading the itemized hospital bill line by line is usually the fastest way to find what is wrong.
Where can you complain if a company ignores your dispute?
If the company stalls, ignores you, or threatens collections while a dispute is open, you can file a complaint with the Consumer Financial Protection Bureau (for financial products), your state attorney general, or the BBB. For credit card charges, dispute through the card issuer; while it investigates, the issuer can't require you to pay the disputed amount or report it as late.
