Mont. Code Ann. § 27-31-102

Any religious, benevolent, literary, or scientific corporation or any corporation bearing or using or being known by the name of any benevolent or charitable order or society may by petition apply to the district court of the county in which its articles of incorporation were originally filed or in which its property is situated for a change of its corporate name. Such petition must be signed by a majority of the directors or trustees of the corporation and must specify the date of the formation of the corporation, the name proposed, and the reason for the change of name. Upon the filing of the petition, the same procedure shall be followed as upon applications for changes of names of natural persons.
