How to Write a No Trespassing Letter. Property owners can issue verbal or written warnings to trespassers, forbidding these intruders from entering their property without permission. To reduce the chances an offender suing you, a written trespass warning detailing the violation and repercussions can be more effective.
Format Your Letter
Research your state's "No Trespassing" statute. For a statute to be legally authoritative, it must state who is at risk of violating the law, the actions he must take or avoid and the penalties for infractions. The statute does most of the work for you, and should compose the bulk of the letter.
The letter should include the name of the offender, the address of the premises forbidden to this person and for how long the offender must stay away.
The letter should stipulate that if the offender re-enters the premises without permission, the owner will call the police and press charges.
Sign the letter and date it. The letter should be signed by someone with the authority to represent the property, such as the owner, security guard or business manager.
Write your "No Trespassing" letter and send it via certified mail. This provides evidence that the letter arrived at the recipient's home.
Escort the offender from the premises at an appropriate time after the violation. If the person returns, the violation is officially a trespass, and you can issue another warning or ask the police to make an official arrest.
