What is required for an individual to legally remove a trespasser in Arizona?

In Arizona, the appropriate legal approach to removing a trespasser is to contact law enforcement. Property owners have the right to defend their property, but this is best achieved through the proper channels, particularly when it involves dealing with individuals who refuse to leave on their own.

Law enforcement officers are trained to handle trespassing situations and can ensure that the removal is conducted legally and safely. Engaging law enforcement also helps prevent potential escalation into conflict or violence between the property owner and the trespasser.

The other options, while they may reflect common misconceptions about how to handle trespassers, do not fulfill the legal requirement. A verbal warning may not hold legal weight if the situation escalates, a signed written notice doesn't have a statutory basis as a requirement in Arizona, and simply showing proof of property ownership does not grant an individual the immediate authority to forcibly remove someone from their property. Thus, contacting law enforcement ensures adherence to the law while promoting the safety of all parties involved.
