R.I. Gen. Laws § 24-12-15
If any lands, or interests therein, in which any infant or other person not capable in law to act in his or her own behalf is interested, are taken by the authority under the provisions of this chapter, the superior court, upon the filing therein of any petition by or in behalf of an infant or other person, may appoint a guardian ad litem for the infant or other person, and the guardian may appear and be heard in behalf of the infant or other person; and the guardian may also with the advice and consent of the superior court and upon such terms as the superior court may prescribe, release to the authority all claims for damages for the lands of the infant or other person or for any interests therein. Any lawfully appointed, qualified, and acting guardian or other fiduciary of the estate of any infant or other person, with the approval of the court of probate within this state having jurisdiction to authorize the sale of lands and properties within this state of any infant or other person, may, before the filing of any petition, agree with the authority upon the amount of damages suffered by the infant or other person by any taking of his or her lands or of his or her interests in any lands, and may, upon receiving the amount, release to the authority all claims of damages of the infant or other person for the taking.
