Statute of Limitations on Debt Collection in Colorado

Short answer Colorado generally gives 6 years for an action to recover a liquidated debt or an unliquidated but determinable amount of money, while other contract actions generally get 3 years. The statutory distinction is not written versus oral. A debt claim accrues when the debt becomes due; a signed writing is required for a general acknowledgment or promise, while the statutes separately preserve the effect of a principal or interest payment.

Governing lawColo. Rev. Stat. §§ 13-80-101(1)(a) (3 years for contract actions unless § 13-80-103.5 applies) and 13-80-103.5(1)(a) (6 years for liquidated debt or a determinable amount)
Written contract/debt deadlineWriting is not the statutory dividing line: 6 years for liquidated debt or an unliquidated, determinable amount (§ 13-80-103.5(1)(a)); otherwise the general contract period is 3 years (§ 13-80-101(1)(a))
Oral contract/open account deadlineSame rule as written debt; the statutes distinguish liquidated or determinable debt from other contract actions, not oral from written (§§ 13-80-101(1)(a), 13-80-103.5(1)(a))
When the clock startsA debt, obligation, money owed, or performance claim accrues when it becomes due (§ 13-80-108(4)); an open account for goods or services accrues at its last proved item (§ 13-80-108(5))
Can a payment or promise restart the clock?A general acknowledgment or promise must be signed in writing (§ 13-80-113); §§ 13-80-113 and 13-80-115 separately preserve the effect of a principal or interest payment, but a creditor's own notation is insufficient proof
Special rule for consumer debtNo creditor-suit period keyed solely to consumer status appears in these provisions; UCCC claims generally get 3 years, while § 5-5-201 sets separate consumer-remedy deadlines for specified violations (§ 13-80-101(1)(g))
Out-of-state debtThe 3-year list includes actions accruing outside Colorado when the place of accrual has a longer limitations period (§ 13-80-101(1)(k)); § 13-80-103.5 has no parallel text
What expiration actually doesThe applicable sections require the action to be commenced within 3 or 6 years after accrual 'and not thereafter' (§§ 13-80-101(1), 13-80-103.5(1))

Requirements one by one

Governing law

Colorado's general contract provision is § 13-80-101(1)(a), which requires contract actions to be commenced within 3 years after accrual unless § 13-80-103.5 provides otherwise. Section 13-80-103.5(1)(a) supplies the 6-year provision for a liquidated debt, an unliquidated but determinable amount of money, and specified debt-evidencing or debt-securing instruments.

How long you have on a written debt

The statutory text does not create a written-contract period. A written claim that seeks a liquidated debt or an unliquidated but determinable amount falls within § 13-80-103.5(1)(a)'s 6-year rule; another contract action generally falls within § 13-80-101(1)(a)'s 3-year rule.

How long you have on an oral or unwritten debt

The same provisions apply without creating a separate oral-contract period. The statutory question is whether the action fits the debt or determinable- amount language of § 13-80-103.5(1)(a), not whether the agreement is oral.

When the clock starts

Section 13-80-108(4) says a claim for debt, obligation, money owed, or performance accrues when it becomes due. Section 13-80-108(5) adds a specific rule for an open account for goods or services: accrual occurs at the time of the last item proved in the account. Section 13-80-108(6) separately uses a discovery-based rule for a cause of action for breach of an express or implied contract, agreement, warranty, or trust.

Can a payment or promise restart the clock?

Section 13-80-113 requires an acknowledgment or promise to be signed in writing before it can serve as evidence of a new or continuing contract that takes the case outside the limitations statute. The same section preserves the effect of a principal or interest payment. Section 13-80-115 likewise preserves a payment's effect but says an endorsement or memorandum written by or for the payee is not sufficient proof of payment.

Is there a special rule for consumer debt?

Section 13-80-101(1)(g) puts Uniform Consumer Credit Code claims in the 3-year list except for § 5-5-201(5). Section 5-5-201 separately gives consumers remedies for specified violations and sets 2-year or 1-year deadlines for certain consumer actions. Those deadlines do not state a different period for the creditor's action on the underlying debt.

What if the debt originated in another state?

Section 13-80-101(1)(k), within the 3-year list, covers actions accruing outside Colorado when the limitations period at the place of accrual is greater than Colorado's. The separate 6-year statute, § 13-80-103.5, does not repeat that foreign-accrual language.

What actually happens once the deadline passes?

Sections 13-80-101(1) and 13-80-103.5(1) both say the covered action must be commenced within the stated period after accrual and not thereafter. Section 5-5-201(4), in the Consumer Credit Code, separately states that a violation of that code generally does not impair rights on a debt.

What trips people up

Writing alone does not select the period. The 6-year provision turns on a liquidated debt or a determinable amount, while the 3-year provision covers contract actions not otherwise placed in § 13-80-103.5. For payments, a creditor's endorsement or memorandum is not by itself sufficient proof under § 13-80-115.

Common questions

Does a signed agreement automatically get 6 years? No. Section 13-80-103.5(1)(a) asks whether the action recovers a liquidated debt or an unliquidated but determinable amount; § 13-80-101(1)(a) supplies the general 3-year contract period when the 6-year section does not apply.

I made a small payment on an old debt, did that restart the clock? Sections 13-80-113 and 13-80-115 preserve a payment's effect separately from the signed-writing rule for an acknowledgment or promise. Section 13-80-115 also limits what counts as sufficient proof of payment.

Do § 5-5-201's 1-year and 2-year periods replace the contract deadline? No. Those periods govern specified consumer claims over Consumer Credit Code violations. They do not state the creditor's deadline to sue on the debt.
