Mont. Code Ann. § 70-31-304

When a condemnation proceeding is instituted by an agency to acquire real property for a program or project for which federal financial assistance is available and the final judgment is that the real property cannot be acquired by condemnation or that the proceeding is abandoned, the owner of any right, title, or interest in the real property must be paid a sum that will, in the opinion of the court, reimburse the owner for the owner's reasonable attorney, appraisal, and engineering fees actually incurred because of the condemnation proceedings. The award of the sum must be paid by the agency that sought to condemn the property.
