Collector contacted you about a debt? Under FDCPA §809(b), you generally have 30 days after you receive their validation notice to dispute it in writing. Once you do, they must pause collection until they mail you verification. You can ask for proof of the debt, the amount, and their right to collect it — the law only requires basic verification.
Send your request by the dispute deadline printed on the collector's validation notice — generally 30 days after you receive it.
Cites FDCPA §809(b) correctly. No "609 letter" garbage.
CERTIFIED MAIL ONLY. Proof of delivery = proof of your timely demand.
