Mont. Code § 15-16-401
Unless suspended or cancelled under the provisions of 15-23-708 or Title 15, chapter 24, part 17, every tax has the effect of a judgment against the person, and every lien created by this title has the force and effect of an execution duly levied against all personal property in the possession of the person assessed from and after the date the assessment is made. The county treasurer may issue a writ of execution for delinquent personal property taxes, unless suspended or cancelled under the provisions of 15-23-708 or Title 15, chapter 24, part 17, and deliver the writ to the sheriff of any county in the state in which the property or some part of the property is located. Writs of execution may be issued at the same time to different counties. The sheriff shall proceed upon the writ in all respects, with like effect, and in the same manner prescribed by law in respect to executions issued against property upon judgments of a court of record. The sheriff is entitled to the fees, mileage, and costs as provided in 7-32-2141 and 7-32-2143, which must be assessed against the delinquent taxpayer. The judgment is not satisfied nor the lien removed until the taxes are paid or the property sold for the payment of the taxes.
