Mont. Code Ann. § 27-19-307

On a hearing to show cause, the judge may require a new undertaking, in the same or a different sum, to be given by the party who obtained the order, with similar sureties and to the same effect as upon granting of the original order. The persons executing the new undertaking become liable as if they had executed the surety upon the granting of the original order. The persons who executed the original undertaking remain liable only until the new undertaking is given and approved. A new undertaking must comply with the provisions of 27-19-306.
