What does a debt validation letter do?

It forces the debt collector to stop collection activity until they produce written validation of the alleged debt — proof of the original creditor, an itemized accounting, the original signed contract, and proof of legal authority to collect. Many third-party debt buyers cannot produce this paperwork, which often kills the case.

Do I have to send it in 30 days?

You should. The FDCPA gives you 30 days from receipt of the collector's initial written communication to dispute the debt in writing (15 U.S.C. § 1692g). Sending inside the window suspends collection until they validate. Sending after the window is still useful but does not trigger the automatic collection-stop.

Should I send it certified mail?

Yes — USPS Certified Mail with Return Receipt Requested. The green card with a postmark is the gold-standard proof you sent the dispute. Save it forever. Without it, a collector can deny receiving the dispute and resume collection.

Is this letter legal advice?

No. SynthCounsel is not a law firm. The wizard generates a letter using standard FDCPA citations, but a licensed attorney should review your specific situation if the alleged debt is large, you've already been sued, or the collector has filed with credit bureaus.

FDCPA validation letter

Force the collector to prove it.

Under 15 U.S.C. § 1692g(b), you have 30 days from a collector’s initial letter to demand written validation. Until they produce it, they cannot legally continue collecting. Many can’t. The wizard below builds the letter for you — free.

Use a real mailing address — the FDCPA validation right requires written notice that the collector can mail back to. P.O. boxes are fine.
