Keith,
I understand 'the neighbor from Hell' as he lives next door to me.
One day when I was not home he came into my yard with a lawnmower and cut down everything that was green...25 feet over the property line! I put up a new clothesline and the next day he put his lawn sprinkler on and watered 25 feet into my yard...all over the clothesline.
I checked with the police and this is what they said. There is something called a 'good neighbor bond'. It is like a restraining order, but since you and the other guy are neighbors it states that the neighbor must respect the property line and not trespass on your side or damage/cut/mow anything in your yard. It only costs about $25 to file the paperwork. Once the paperwork is filed...(here comes the good part)...the next time the neighbor does something wrong...violates the order...you call the police and the man/woman will be arrested on the spot. Period.
In this photo you can see the landscape timbers that represent the property line. That does not stop the 'neighbor from Hell'...but the Good Neighbor Bond works pretty darn good.
Guess you can figure out that in the photo the 'Neighbor from Hell' lives on the left and I live on the right.
