If you illegally enter someone's property or stay there without their permission, you've committed the offense of trespass. By committing this offense, you can face civil liability as well as criminal charges.

Notice Requirements in Missouri

Property owners must give would-be trespassers notice that they can't come onto the property. In Missouri, an owner meets the notice requirements by installing a fence, telling the person that they can't enter the property, posting a "No Trespassing" sign, or by marking property with purple paint in a way that is described in the statute.

Overview of Missouri Criminal Trespass Laws

Because of the way that statutes are written, it can be difficult to read them in their entirety and understand exactly what they convey. For the most accurate analysis, it's best to work with an attorney for complex cases. However, if you just need simple clarification or need an introduction to the law before meeting with the attorney, refer to a plain English guide to the statutes. See the chart below for a simple overview of Missouri's criminal trespass laws.
