Mont. Code § 39-3-510
Upon the hearing of such order, if the court shall determine that the default of said employer in the payment of wages and salaries was willful or that the financial condition of the employer is such as to endanger or delay or impede employees in collecting their wages and salaries or that the employer is a nonresident of the state without visible property in said county subject to execution or who has within 2 years defaulted in payroll payments, the court may adjudge and decree that the employee or employees are endangered in the collection of their just demands and the court may issue a restraining order against the employer forbidding further prosecution of operations by said employer until after the employer has furnished a good and sufficient bond, in form to be approved by the court with good and sufficient surety or sureties who can and do legally justify, and deposit said bond with the clerk of court of said county obligating the employer to pay all wages and salaries as required by part 2 of this chapter.
