My daughter has a 3.5acre farm in Grass Valley adjacent to another property. Several owner back, the other property built a fence on the property line between the two properties. The current owner whoo recently bought the adjacent property thinks he is the owner of the fence and is trying to prevent her from attaching anything to the fence. We advised him of the CA 'boundary' fence law, but he is adamant. Will iy be expensive for you to inform him of her rights?
