Colorado Revised Statutes Title 38. Property Real and Personal § 38-26-104. Contractor furnished copy--undisputed accounts--condition

Whenever any verified account mentioned in section 38-26-103 is placed in the hands of any railroad, reservoir, or irrigating canal company, or its agent, it is the duty of such company to furnish the contractor with a copy of such verified account so that if there is any disagreement between the debtor and creditor as to the amount due the same may be amicably adjusted. If the contractor or subcontractor, if he is the debtor, does not give, within ten days after the receipt of such amount, the same railroad, reservoir, or irrigating canal company, or its agent, written notice that the claim is disputed, he shall be considered as assenting to its payment and the railroad, reservoir, or irrigating canal company, or its agent, shall be justified in paying the same when due and charging the same to the contractor. The person to whom any such debt is due and who delivers a verified account thereof as provided may recover the amount thereof in an action at law to the extent of any balance due by the railroad, reservoir, or irrigating canal company to the contractor at or after the time of delivering the verified account. Nothing in this section or in section 38-26-103 shall interfere with the right of action upon bonds provided for in section 38-26-102 or against the railroad, reservoir, or irrigating canal company for the full amount of any such debt in case of a failure of the company to take a bond.
