Mont. Code § 87-5-912
A lease or conservation easement selected to receive funds pursuant to this part binds the parties involved to an agreement in which the state is a third-party beneficiary to the lease or easement with the contingent right to enforce the terms of the lease or easement if the grantee fails to do so. The agreement must provide that the lease or easement may not be transferred for value, sold, or extinguished without consent of the department. The state may take legal action to enforce the terms of the lease or easement or to recover from the proceeds of the transfer for value, sale, or extinguishment the state's pro rata share of the proceeds based on the funds the state provided pursuant to this part for the creation of the lease or easement.
