When you are initially contacted by a debt collector regarding an unpaid debt, you have the right to request proof of the debt within 30 days of initial contact. This is called debt validation. Unless the debt collector can validate that you are responsible for the debt, they must stop all further collection efforts.

The debt validation letter from collector needs to include: 1) Proof the debt exists; 2) Proof that you are responsible for the debt; and 3) Proof that the debt collector has legal right to collect on the debt.
