Mont. Code § 20-9-436
The trustees of a school district conducting bond proceedings shall prepare and maintain a transcript of their bond proceedings. It is a part of the official duties of the county attorney of every county of this state to advise and assist the trustees of each school district of the county in its bond proceedings. Before any transcript of school district bond proceedings is sent to the board of investments, the county attorney shall carefully examine the transcript, and the transcript may not be sent until the county attorney has attached an opinion to the transcript that the proceedings are in full compliance with law. However, the trustees of any school district may, upon consent of the county attorney, employ any attorney licensed in Montana to assist the county attorney in the performance of these duties.
