Legal Question in Criminal Law in Virginia

Re: trespass

If the unwanted(from your perspective) house guest

is occupying that part of the property where the owner is residing(and apparently tolerating his continued presence), and which is not covered by your lease, you would have no authority to make this person leave from that area of the property. That, of course, would not apply if in fact this person was intruding into your leased space, and, if so, you could file an unlawful detainer action in the general district court to have him evicted.
