Mont. Code § 77-1-104
If the board considers it necessary that any of the lands mentioned in 77-1-102 be surveyed, it must have the lands surveyed by the county surveyor of the county in which the lands are located. If there is no county surveyor, if the county surveyor is unable to make the survey, or if the best interests of the state require, the board shall appoint a qualified surveyor to make the surveys. The county surveyor or other surveyor appointed shall make an actual survey establishing four corners of every quarter section and connecting the same with a United States survey and within 30 days after the survey file with the county clerk and recorder of that county a copy under oath of the surveyor's field notes and plat and a certified copy of the field notes and plat with the department. For the services required in connection with the survey, the county surveyor or other surveyor appointed is entitled to fees as prescribed in 7-4-2821. The fees must be paid in the same manner as other expenses of the department.
