Colorado Revised Statutes Title 29. Government Local § 29-8-122. Failure to pay installments

Failure to pay any installment, whether of principal or interest, when due shall cause the whole of the unpaid principal to become due and collectable immediately, and the whole amount of the unpaid principal and accrued interest shall thereafter draw interest at the rate of one percent per month or fraction of a month until the day of sale; but at any time prior to the day of sale, the owner may pay the amount of all unpaid installments, with interest at one percent per month or fraction of a month, and all penalties accrued, and shall thereupon be restored to the right thereafter to pay in installments in the same manner as if the default had not been suffered.
