I'm being sued for an accident that wasn't my fault
On Dec, 20th my younger sister was hit by a woman who ran a red light and her car was totaled. Unfortunately times are tough and she didn't have insurance at the time. The accident was obviously the other drivers fault because my sisters car was knocked completley in the other direction. My sister was young and didn't know to get a witness to stick around as well as to make matters worse the woman lied and said it was my sister who ran the light, even though the positions of the vehicles afterwards obviously pointed to the other woman being at fault, no tickets were issued and the police report said no one was at fault and I just get a letter in the mail today from the woman's lawyer trying to sue us for 300,000 dollars in damages and injuries. This is ridiculous. It doesn't make you a bad person because you can't afford insurance but it does make you a bad person when you are twice the age and size of the victim and are trying to take advantage and collect free money. What should I do?
