R.I. Gen. Laws § 28-35-42
If any payment of compensation is not paid within fourteen (14) days after it becomes due, there shall be added to that unpaid payment an amount equal to ten percent (10%) of it, which shall be paid at the same time as, but in addition to, that payment, unless the nonpayment is excused by the workers' compensation court after a showing by the employer or his or her insurer that owing to conditions over which he or she had no control the payment could not be paid within the period prescribed for the payment. However, if within one year next preceding the due date of any payment which is not paid within fourteen (14) days after it becomes due, two (2) or more payments payable under the terms of the agreement have not been paid within fourteen (14) days after those payments have become due, it shall be conclusively presumed that the failure of the employer to make the instant payment was owing to conditions over which the employer had control.
