Serve the tenant with a 5 day notice to pay rent or quit the premises. This starts the summary eviction process. If they respond or don't pay rent within 5 days then you file an affidavit of complaint for summary eviction with the justice court. You may need to appear in justice court to present your side.
Look at the summary eviction portion of chapter 40 of the NRS for guidance
