A debt validation letter is your formal request to a debt collector to prove that a debt is actually yours and that they have the legal right to collect it. You send this within 30 days of first contact, demanding evidence like the original contract or account statements. It’s a key consumer protection tool under the FDCPA, helping you verify claims before paying or disputing.
