Legal authority

  • C.R.S. § 10-4-609 (Insurance Protection Against Uninsured Motorists; UIM defined at subsection (4))
  • C.R.S. § 10-4-610 (Property Damage Protection Against Uninsured Motorists)
  • C.R.S. § 10-3-1115 (Unreasonable Delay or Denial of Benefits)
  • C.R.S. § 10-3-1116 (First-Party Claimant — Bad Faith Damages)
  • C.R.S. § 13-80-101(1)(n) (three-year category for underlying motor-vehicle bodily-injury/property-damage torts, subject to stated exclusions)
  • C.R.S. § 13-80-107.5 (Specific Limitation Period for UM/UIM Actions and Arbitrations)

Personal injury cases are brought by people who were hurt because of someone else's carelessness: car crashes, slip and falls, defective products, and more. Demand letters, settlement agreements, and court filings in these cases have to document the injuries, the medical treatment, the lost income, and the exact legal basis for holding the other side responsible. Well-prepared paperwork is what drives higher settlements and forces insurers to take the claim seriously.
