A single inaccurate late payment can drop your credit score by dozens of points. If you actually paid on time, the Fair Credit Reporting Act gives you the right to have it removed — for free.
You can dispute a late payment whenever the entry is inaccurate or unverifiable. Common situations include:
The strongest disputes include evidence. Pull together copies of bank or credit-card statements showing the payment posted, cancelled checks, confirmation emails, or auto-pay records. You'll attach copies (never originals) to your letter so the bureau can verify quickly.
There are two different approaches, and they're often confused:
Dispute letter (use when the late payment is wrong): You assert the information is inaccurate and the bureau must investigate under 15 U.S.C. § 1681i. If the furnisher can't verify it, it must be deleted. This is what our generator produces.
Goodwill letter (use when the late payment is accurate but a one-off): You politely ask the creditor — as a courtesy — to remove an isolated late mark on an otherwise good account. Creditors are not required to agree, and bureaus won't remove accurate data, so this is a request, not a right.
Once mailed, the bureau generally has 30 days to investigate and respond in writing. If the late payment was inaccurate and the furnisher can't substantiate it, expect it to be corrected or removed and your score to recover.
