Mont. Code Ann. § 70-28-108

Before the plaintiff is entitled to a decree in an action against any defendant who does not appear in the action, the plaintiff shall produce evidence sufficient to prima facie entitle the plaintiff to relief. The relief may be granted only to the extent to which the evidence prima facie proves the plaintiff to be entitled to the relief. However, this provision may not affect the procedure in or manner of trial of the actions as between the plaintiff and any defendant who appears in the action.
