Mont. Code Ann. § 80-2-208

The board may write not more than $75 of insurance on each acre of crops on nonirrigated land and not more than $114 of insurance on each acre on irrigated land, except that the board may specify different maximums for specialty crops. When more than one party desires hail insurance on the same crop, each party is entitled to the share of the maximum provided on each acre as represented by that person's interest in the crop. Any party may insure the party's share in the crop for any amount up to and including the maximum on each acre if the other parties waive their right to insure.
