A.__A commitment of a juvenile to a Department of Human Services juvenile correctional facility pursuant to section 3314 must be for an indeterminate period not to extend beyond the juvenile's 18th birthday unless the court expressly further limits or extends the indeterminate commitment, as long as the court does not limit the commitment to less than one year nor extend the commitment beyond a juvenile's 21st birthday and as long as an order does not result in a commitment of less than one year, unless the commitment is for an indeterminate period not to extend beyond the juvenile's 21st birthday.__Nothing in this Part may be construed to prohibit the provision to a juvenile following the expiration of the juvenile's term of commitment of services voluntarily accepted by the juvenile and the juvenile's parents, guardian or legal custodian if the juvenile is not emancipated; except that these services may not be extended beyond the juvenile's 21st birthday.

B.__A commitment of a juvenile to the Department of Human Services pursuant to section 3314 must be for an indeterminate period not to extend beyond the juvenile's 18th birthday unless the court expressly further limits the commitment.

3.__Voluntary services.__This subsection applies to voluntary services agreement provisions.

A.__This chapter does not prevent a juvenile from receiving services from the Department of Human Services pursuant to a voluntary agreement with the juvenile and the juvenile's parents, guardian or legal custodian if the juvenile is not emancipated.

B.__If a juvenile is placed in a residence outside the juvenile's home pursuant to a voluntary services agreement, the Commissioner of Human Services or the commissioner's designee may request the court to make a determination of whether reasonable efforts have been made to prevent or eliminate the need for removal of the juvenile from the juvenile's home and whether continuation in the juvenile's home would be contrary to the welfare of the juvenile.__If requested, the court shall make that determination prior to the expiration of 180 days from the start of the placement and shall review that determination not less than once every 12 months until the juvenile is no longer residing outside the juvenile's home.
