R.I. Gen. Laws § 37-6-17
If any party shall agree with the acquiring authority upon the sum to be paid for the value of the land or other real property so taken and of appurtenant damage to any remainder or for the value of his or her estate, right, or interest therein, and the price shall be approved by the state properties committee, the price shall be paid to him or her forthwith. The state controller is authorized and directed, upon receipt by him or her of proper and duly authenticated vouchers, to draw his or her order upon the general treasurer for the payment of the agreed price out of any funds appropriated and available therefor; provided, however, that if any party shall fail to agree with the acquiring authority upon the sum to be paid for the value of the land or other real property so taken and of appurtenant damage to any remainder or for the value of his or her estate, right, or interest therein, then, the state properties committee, upon the application of the party in interest and of the joinder of all other parties in interest shall order paid forthwith, to the party or parties so applying for or on account of the just compensation to be awarded under a petition filed or to be filed in the superior court for the assessment of damages, in accordance with the provisions of this chapter, not less than one hundred percent (100%) of the acquiring authority's offer pending final disposition of the court proceeding. The verdict and the judgment thereafter entered in the court proceeding shall not include any item for interest upon such amount as shall be or could have been ordered paid by the state properties committee on account of the just compensation for any period of time from and after thirty (30) days following the making in writing of the acquiring authority's offer.
