N.H. Rev. Stat. § 169-B:31
Upon making a finding that the purposes of this chapter have been met with regard to the minor named in the petition, or for such other reason the court may deem appropriate and consistent with the purposes of this chapter, the court may order a case closed. Any case remaining open for 12 months after the date of the disposition shall be reviewed by the court annually and closed, unless the court finds by a preponderance of the evidence that the continued provision of services and court involvement are necessary and shall be fruitful to rehabilitate the minor or protect the public interest. All such findings shall be in writing and shall include the basis upon which those findings were made. Upon request by the child, the court shall also review any case in which the child remains at the youth development center more than 6 months after the order of commitment without having been released on parole or having been returned to the youth development center following revocation of parole. Successive requests for review shall be granted upon request by the child but the court may deny such requests without a hearing if a review was held less than 90 days prior to receipt of a request for review. In each instance that the court reviews a case in which the child remains at the youth development center at the time of review, the child shall be entitled to the assistance of counsel, which may not be waived except following consultation between the child and a parent or counsel. Consultation between a child and parent is not sufficient to support waiver under this section if the parent was a victim or complainant in the underlying proceeding or has been a witness or provided information in support of the basis for revocation in a parole revocation proceeding involving the child. Children known to the department of health and human services or the court to have an emotional disorder, intellectual disability, or any other condition which may be expected to interfere with a child's ability to understand the proceedings, make decisions, or otherwise handle the proceedings without the assistance of counsel may not waive the right to counsel guaranteed by this section.
