P.R. Laws tit. 3, § 2304
Whenever a payment is not made within the term established in this chapter, the purveyor concerned may present a written demand for payment before the head of the agency to which goods or services have been provided, requesting payment within a term of ten (10) working days starting on the date such demand for payment is filed. The head of the agency or the employee or official designated as his authorized representative shall reply to said demand for payment in writing, and shall state if there is any question on the existence of the obligation, amount of payment, delivery of goods or rendering of services and the condition thereof, or any other fact which may have prevented the processing of the payment as established in this chapter. The agencies shall establish administrative rules and procedures for the informal solution of these controversies in a speedy, fair and thrifty manner.
If there is no controversy, the head of agency shall submit the necessary documents to the Secretary or payer to process the payment, within a term that shall not exceed five (5) working days counting from the date in which the demand for payment is filed. The Secretary or payer shall make the payment in a term that shall not exceed five (5) working days following the date of receipt of the documents that make the payment viable.
In cases where there is no controversy, noncompliance with the payment within the term of ten (10) working days provided in this section shall result in the imposition and payment of legal interest charges, from the date on which the demand for payment was filed. If the noncompliance within said term could be ascribed to the agency, it shall pay the interest charges. If said noncompliance could be ascribed to the Secretary, the interest shall be charged to the budget of the Department of Treasury. An annual appropriation shall be provided to the agencies to defray the expenses for interest that could be imposed by virtue of this chapter.
