If a Plaintiff (Debt collector acting for original creditor(plaintiff) sent a letter to inform me about a debt I supposedly own and I don't send a letter of validation. I attended a pretrail and I denied the claims and we are going to trial. The debt collector acting for the original creditor (plaintiff) sent me a "Motion for discovery and to continue trial" and a "motion for summary final judgment" but they have never validate the debt. Can I still make then validate the debt now?
