Trespass victims can call the police or file a police report about the trespass. If possible, victims may wish to videotape or photograph the trespass to serve as evidence. Trespass victims may also file a civil lawsuit against the trespasser. The plaintiff (trespass victim) would need to prove that the defendant (trespasser) intentionally intruded on the plaintiff's property in order to recover damages. If the defendant caused property damage, the plaintiff can ask the court for compensatory damages to cover the cost of any repairs. If no damage was done, the defendant can still ask the court for nominal damages. If the defendant acted maliciously, the plaintiff can ask the court for punitive damages to punish the defendant. If the trespasser is posing an immediate threat of injury, then the property owner or tenant can act in self-defense with reasonable and proportional force. In Nevada, homeowners or tenants do not have a duty to retreat when an intruder breaks into an occupied residence or vehicle; under the Castle Doctrine, the homeowner or tenant can even use deadly force to prevent what reasonably appears to be a home invasion.
