Unfortunately a few times.
I think my favorite was because of my former neighbor. We had a real Hate/Terrified relationship that he started. He hated my plants which he managed to destroy, my car, the color of my house - just a plain neutral beige, he wanted it to be white. I found out I was being sued when I received an invitation to appear on Hot Bench, a show in Chicago and Judge Judy. He claimed I hit his car. Our driveways were against each other and he sued for me purposely hitting his car with my door and actually HITTING his car. He parked as close as humanly possible to my car every chance he got. He even went out and moved his car closer one time, we watched him. I took precautions to not even step in his driveway if I could avoid it.
I turned his claim over to my insurance company and after an investigation, and his failure to show up for 5 appointments to have his vehicle inspected, they found no damage and no fault on my part. He filed suit against me. My insurance company sent a lawyer to represent us thankfully. I love to take pictures and was able to rebut every single claim he made. The judge tossed the case, again in my favor. They wouldn't let me leave the courtroom for a half hour after he left for my protection. There was a real fear that he would try to harm me. My husband was a sheriff and his co-workers were aware of threats he had made against me before.
I lived in pure terror for 5 years, actually afraid to leave my house. I was thrilled when a For Sale sign went up on his lawn the next day. The new neighbors are lovely people and he even gave them issues buying his house right up to the day they signed the final papers. What a sad way to live your life.
I heard he moved to an HOA development so he should be happy there. Everyone has to conform to his way of viewing the world.
