R.I. Gen. Laws § 24-1-11
If any real property or any estate or interest therein, in which any infant or other person not capable in law to act in his or her own behalf is interested, is taken under the provisions of this chapter, the superior court, upon the filing therein of a petition by or in behalf of the infant or person or by the city or town council, may appoint a guardian ad litem for the infant or other person. Guardians may, with the advice and consent of the superior court, and upon such terms as the superior court may prescribe, release to the city or town all claims for damages for the land of the infant or other person or for any estate or interest therein. Any lawfully appointed, qualified and acting guardian or other fiduciary of the estate of the 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 the infant or other person, may before the filing of a petition, agree with the city or town council upon the amount of damages suffered by the infant or other person for any taking of his or her real property or of his or her interest or estate therein, and may, upon receiving such amount, release to the city or town all claims for damages for the infant or other person for the taking.
