How To Write A Debt Validation Letter

What Is a Debt Validation Letter?

A debt validation letter is a letter you send to a debt collector. It asks the collector to prove the debt is real, that it belongs to you, and that the amount is correct. Federal law — the Fair Debt Collection Practices Act (FDCPA) and Regulation F — gives you the right to ask for this proof.

Your 30-Day Window

You generally have 30 days from the date on the collection letter to demand validation. This window is computed from the letter date, not from the day you read it.

Don't pay or promise to pay before you get validation.
Send your request before the 30 days run out, if you can.

Could the Debt Be Too Old? (Florida statute of limitations)

Florida law, Fla. Stat. 95.11, sets a time limit on how long a debt can be collected through the courts. An old debt may be past that window. But the clock has exceptions: a payment or a written acknowledgement of the debt can restart it. Whether your debt is time-barred depends on facts that only a professional review can weigh.

What the Letter Should Say

Federal and Florida collection law require certain disclosures in a collection letter, and give you rights and limits on what collectors can do. Florida's Consumer Collection Practices Act (FCCPA), Fla. Stat. 559.55–559.785, adds state-level rules on top of the federal FDCPA and Regulation F.

Ask the collector to identify the original creditor and the amount owed.
Ask them to prove the debt is yours.
State that you dispute the debt until it is validated.
Keep a copy of your letter, and send it by certified mail.

What Collectors Can't Do

The FDCPA, Regulation F, and Florida's FCCPA set limits on what collectors can say and do while trying to collect a debt from you.

What to Do Next

This is general information, not legal advice. It can't tell you whether you owe this debt or whether it is time-barred under Florida law. For that, contact Florida legal aid at floridalawhelp.org, the CFPB, or a consumer attorney — FDCPA cases often cost you nothing.

The free Debt Letter Decoder tool reads your own collection letter or the numbers and dates you paste in. It checks what's required, computes your 30-day validation deadline from the letter date, flags whether the debt may be past Florida's statute of limitations, and gives you a validation letter ready to send by certified mail.
