Debt validation: how it works and what counts as proof
Before you pay a collector, you have the right to see what they are collecting and to make them back it up. The process has a deadline, so it helps to know how it works.
The validation notice
A collector has to send you a validation notice in its first contact with you, or within five days after. Since late 2021 most notices follow the CFPB’s model form, and every notice must include:
- The collector’s name and mailing address, and your name and address.
- The creditor on the “itemization date” and the account number, plus the name of the current creditor.
- The amount owed on the itemization date, then the interest, fees, payments and credits since, and the current amount.
- The end date of the validation period, with instructions for disputing, usually a tear-off form you can mail back.
The validation period
The period ends at least 30 days after you receive the notice, and the notice gives you the exact date. Inside that window you have two strong rights:
- Dispute the debt in writing. The collector must stop collecting until it mails you verification.
- Ask for the original creditor’s name and address in writing. The collector must stop collecting until it sends that.
The collector can’t use the period to pressure you in ways that drown out these rights, for example by demanding payment “today” in a way that contradicts the dispute deadline.
What counts as verification
Be realistic here. Courts often accept fairly basic verification, such as a statement from the original creditor confirming the amount and that the account is in your name. You can ask for more, like the signed agreement and proof the collector owns the debt, and our letter does. The collector may not be required to send all of it, but what it sends, or can’t send, tells you a lot. If you are ever sued, a collector that couldn’t document the debt will have a harder time.
If the collector doesn’t answer
After a timely written dispute, a collector that doesn’t send verification can’t go back to collecting. It may simply close the account or send it back to the creditor. It isn’t allowed to keep calling or sending demands as if nothing happened. If it reports the debt to the credit bureaus, it must show the debt as disputed.
If you missed the deadline
You can still dispute and ask for proof. The collector doesn’t have to pause while it responds, but it still can’t report the debt without noting your dispute, and the other rules still apply.
After verification
- It is yours and the amount is right: you can pay, set up a plan, or negotiate a settlement. Get any deal in writing first.
- It is old: check the statute of limitations before paying, because a payment can restart it in many states.
- It is still wrong: dispute with the credit bureaus too, and consider a complaint to the CFPB.
