did a removal for a lady last year, nothing special about the tree, finished grinding the stump, cleaned up and left. There were a few red flags here n there, like asking to do one more thing here n one more thing there, nothing too serious. The next day HO called and complaining about a cut sprinkler wire under the roots and demanding me to come repair it. I explained to her that if it's not marked and I did not know it was there I'm not responsible to it and this is industry standard. Everything seems cool after that. However, over 8 months later, yesterday, she texted me with a 400 repair bill (not too much) and asked me to pay for it. I explained to her that we went through this 8 month ago and it's not my fault. she then threatens to sue me. She has some kind of legal insurance like MetLife (Hyatt). I guess since it doesn't cost her anything to sue someone it makes it easier to do anyway. What do u guys think? I hear a lot here and other places that she doesn't have any legal base, but wondering if there's any real known legal precedence that I can use if we were to actually face each other in court.
