all actions except those governed by section 4-2-725, C.R.S., brought against a manufacturer or seller of a product, regardless of the substantive legal theory or theories upon which the action is brought, for or on account of personal injury, death, or property damage caused by or resulting from the manufacture, construction, design, formula, installation, preparation, assembly, testing, packaging, labeling, or sale of any product, or the failure to warn or protect against a danger or hazard in the use, misuse, or unintended use of any product, or the failure to provide proper instructions for the use of any product shall be brought within two years after the claim for relief arises and not thereafter.

I acknowledge that similar language is often used in connection with the accrual of a claim. See, e.g., § 13-80-108(1), C.R.S. (2015) ("Except as provided in subsection (12) of this section, a cause of action for injury to person, property, reputation, possession, relationship, or status shall be considered to accrue on the date both the injury and its cause are known or should have been known by the exercise of reasonable diligence.").

Per the verbatim text of C.R.S. § 13-80-103.5(1)(a), actions to recover a liquidated debt or an unliquidated determinable amount of money due, and actions to enforce rights set forth in any instrument evidencing or securing the payment of any debt, must be commenced within six years after the cause of action accrues. A promissory note is a written instrument evidencing a debt, so an action on a promissory-note debt is governed by this six-year period.

Under Colo. Rev. Stat. § 13-80-102(1)(a), tort actions — including negligence, trespass, malicious abuse of process, malicious prosecution, outrageous conduct, interference with relationships, and tortious breach of contract — must be commenced within two years after the cause of action accrues. This is the controlling SOL for general personal-injury / negligence actions in Colorado. Note: tort actions arising from the use or operation of a motor vehicle are excepted and governed by the 3-year l

Per the verbatim text of C.R.S. § 13-80-103.5(1)(a), actions to recover a liquidated debt or an unliquidated determinable amount of money due must be commenced within six years after the cause of action accrues. Credit-card and open-account debt is covered by this receipt only when the obligation is a liquidated debt or an unliquidated, determinable amount of money due.

A Colorado legal malpractice action — a claim for professional negligence against an attorney — must be commenced within two years after the cause of action accrues under C.R.S. § 13-80-102(1)(a). Colorado has no separate, claim-type-specific statute of limitations for legal malpractice; such claims are tort actions (negligence) and route to the general two-year tort lane. Accrual follows the discovery rule (§ 13-80-108(1)): the claim accrues when the plaintiff knows or should know through the e

A Colorado claim for wrongful termination (wrongful discharge in violation of public policy — the common law public-policy exception to the at-will employment doctrine) must be commenced within two years after the cause of action accrues under C.R.S. § 13-80-102(1)(a). Colorado courts consistently characterize this claim as sounding in tort. Colorado has no claim-type-specific statute of limitations for wrongful discharge; such claims route to the general two-year tort lane at § 13-80-102(1)(a).

Under C.R.S. § 13-80-102(1)(a), tort actions — including negligence and trespass — must be commenced within two years after the cause of action accrues.

Note: property damage arising from use or operation of a motor vehicle is excepted to 3 years under § 13-80-101(1)(n).

Under C.R.S. § 13-80-102(1)(a), tort actions — including trespass (expressly enumerated) — must be commenced within two years after the cause of action accrues.

Both are intentional property torts that accrue on the date of the tortious act (or discovery under § 13-80-108 if the plaintiff

§ 13-80-118 tolls the SOL while the defendant is out of state and not subject to service of process. Verbatim statutory language quoted in West Colo. Motors v. General Motors, 2019COA77 (Colo. App.), para. 30. Second source: People v. Butler, 2017COA117, which discusses the criminal tolling analog (§ 16-5-401(2)) for absence from state, confirming the same principle. Historical predecessor § 13-80-126 confirmed in United Bank of Denver National Ass'n v. Wright (1983).

§ 13-80-118 tolls the SOL while the defendant 'has concealed himself' (physical self-concealment). Verbatim language from West Colo. Motors v. General Motors, 2019COA77 (Colo. App.), para. 30. This covers defendant's physical concealment of self from service of process. Common law fraudulent concealment of facts is a separate doctrine confirmed in First Interstate Bank of Fort Collins, N.A. v. Piper Aircraft Corp., 744 P.2d 1197 (Colo. 1987).

When in any of the statutes of the state of Colorado a limitation is fixed upon the time within which a right of action ... may be brought ... and the true owner of said right is a person under disability at the time such right accrues...
