Colo. Rev. Stat. § 5-3-503
If a default exists on a consumer insurance premium loan and any right to cure that exists has expired without cure being effected, the lender may give notice of cancellation of each insurance policy or contract to be canceled. If given, the notice of cancellation shall be in writing and given to the insurer who issued the policy or contract and to the insured. The insurer, within two business days after receipt of the notice of cancellation together with a copy of the insurance premium loan agreement if not previously given to the insurer, shall give any notice of cancellation required by the policy, contract, or law and, within ten business days after the effective date of the cancellation, pay to the lender any premium unearned on the policy or contract as of that effective date. Within ten business days after receipt of the unearned premium, the lender shall pay to the consumer indebted upon the insurance premium loan any excess of the unearned premium received over the amount owing by the consumer upon the insurance premium loan.
