Reviewed by DocDraft Legal Team · Colorado · Last updated 2026-05-18
If you are contesting a charge in Colorado, the rules of the road are Colorado-specific. Colorado Consumer Protection Act (at Colo. Rev. Stat. §§ 6-1-101 through 6-1-1707) is the operative consumer-protection statute. A written demand letter is best practice but not statutorily required for an individual consumer claim (C.R.S. § 6-1-113). The clock on a written-contract debt in Colorado runs 3 years (C.R.S. § 13-80-103.5(1)(a)). The sections below cover the Colorado dispute path: demand letter, evidence assembly, AG complaint, and small claims (up to $7,500).
Key Considerations
Colorado channels disputed-billing claims through Colorado Consumer Protection Act (Colo. Rev. Stat. §§ 6-1-101 through 6-1-1707). A consumer in Colorado also has the option of filing with the AG's office.
Timing matters. Colorado sets 3 years on written contracts, 6 on open accounts, anchored to C.R.S. § 13-80-103.5(1)(a). On debt-collection conduct, Colorado Fair Debt Collection Practices Act, C.R.S. §§ 5-16-101 through 5-16-141 (collection agencies licensing and conduct).
Colorado handles small dollar claims through the Small Claims Division of the County Court, with the jurisdictional ceiling at $7,500. Before filing under the state consumer act, a written demand letter is best practice but not statutorily required for an individual consumer claim (C.R.S. § 6-1-113).
