Definition of Forcible trespass
An invasion of the rights of another with respect to his personal property, of the same character, or under the same circumstances, which would constitute a "forcible entry and detainer” of real property at common law. It consists in taking or seizing the personal property of another by force, violence, or intimidation or in forcibly injuring it. There must be actual violence used, or such demonstration of force as is calculated to intimidate or tend to a breach of the peace. It is not necessary that the person be actually put in fear.
