If the petitioner fails to pay to the parties entitled thereto, or into court, the amount of the award of just compensation before the time for noting an appeal from any final order upon the report of just compensation, the owner or owners of the property to be taken or damaged may, upon motion, obtain as a matter of right an order dismissing the proceeding as to such property. Such order shall also provide that the petitioner shall pay such owner or owners his expenses as provided in § 25.1-249. If any such expenses are not paid within 30 days of the entry of such order, judgment therefor shall be entered against the petitioner.
