Mont. Code § 77-2-351
Notwithstanding any other section in this chapter, any lands may be sold to or exchanged for other land or for other consideration with another public entity on terms and in a manner that the board, after consultation with the appropriate legislative committee, may determine to be in the state's best interest, subject to The Enabling Act and constitutional restrictions. In the case of land that is not granted to or held by the state in trust for the support of the common schools, for a state institution, or for another specific purpose, the board may accept as partial or total consideration for the transfer of the land a binding commitment by the transferee to use the property to provide a community service or a benefit that fulfills a public purpose. The sale or exchange of the property may not be finally concluded until 60 days' public notice of the terms of the proposed sale or exchange has been given. As used in this section, "public entity" means any county, city, municipal corporation, school district, regional water authority provided for in Title 75, chapter 6, part 3, or special improvement or taxing district.
