If any lands, or interests in them, 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 §§ 45-29-1 - 45-29-12 the superior court, upon the filing of a petition by or in behalf of the infant or other person, may appoint a guardian ad litem for that 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 terms that 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 in them. Any lawfully appointed, qualified, and acting guardian or other fiduciary of the estate of an 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 the 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 that amount, release to the authority all claims of damages of the infant or other person for the taking.
