When you think of trespassing, you may not take it seriously. However, trespassing isn't merely an example of rude behavior; it's an invasion of privacy and an interference of someone else's property rights. Although it's generally a minor offense, people who engage in trespassing may not only be liable for a civil lawsuit, but they may also be charged criminally depending on the situation. It can be an offense on its own and can also lead to other crimes such as theft or vandalism. In Illinois, three main incidents of criminal trespass are: criminal trespass to real property (land), criminal trespass to a residence, and criminal trespass to vehicles.

Notice Requirements

When it comes to trespass to real property, one of the ways to commit a trespass is by entering property when you have received prior notice that entry is forbidden. A person is considered to have received notice from the owner if he or she has been notified personally, either orally or in writing, or if a printed or written notice forbidding entry has been posted at the main entrance to the land or the forbidden part. "No trespassing" signs are an obvious indicator, but in Illinois purple paint also signifies notice. Owners may mark the property by placing identifying purple marks on trees or posts around the forbidden area.
