Proof posture
The strongest pressure usually comes after answering: discovery, records objections, standing challenges, and trial proof.
C.R.S. § 5-16-111 requires debt-buyer and covered collection-agency cases to be supported by original-debt documentation and an unbroken assignment chain. Missing required attachments may support a motion to dismiss, an objection to default judgment, or a proof challenge at trial, but it does not guarantee automatic dismissal.
