Trespassing laws can be different in every state and every country. There are both civil and criminal trespassing laws. To trespass means to enter onto another person’s property without permission. What type of trespassing takes place depends on what the trespasser does after the trespass. If a person passes onto someone’s property that may or may not be marked “No Trespassing”, it is generally just a civil crime. However, if a person goes onto someone’s property without permission, and kills livestock that does not belong to him or her, this is generally a criminal trespass. Reasonable force is all that can be used by those who wish to keep their property free from trespassers. The usual advice is to call your local law enforcement agents in order to have a trespasser removed. Fines for trespassing range from $50 to $500, but if other charges such as assault or theft are made, the fines will definitely be higher.
