I hope someone can help me with this situation. So what happened was that about couple weeks ago, I was trying to purchase a nissan car down in New Jersey. I drove into the parking lot of the nissan in Flemington, NJ. I was trying to park my car by turning a slight left. There were cars on the right and left of the spot I was tring to park. So a girl sat on the right car suddently open up her drive side door ( the car is a hatchback which if I could recalled has tinted window.) I braked my car, but that was too late. My front passenger headlight is crashed into the door ( the region on the her door is neither inside nor outsite. It was like edged). I got off the car and asked if any one is ok. And then, I backed up my car because the girl needed to walk out of the car. I was silly enough to not take the photo immediately. I took some photos afterward such as my car's passenger head light, the girl's car's door, and the position of both cars in various view. So we called town police and the insurance company. It turns out that our insurance company is both geico. I talked to the agent regarding to the accident. I answered many questions to the agent and the police. Before the police left, he told he me " it was her fault. So basically what happened is that the girl opened up her door into my parking spot suddently, I didn't have enough time to respond." So the police left without giving any of us troubles. The insurance agent talked to both the girl and me and told me that she was closing my claim number because that was her fault and it is her responsbility for the accident. Her policy had to cover my repair expense. The agent gave me the girl's claim number. I left the scene with relief. But, one week after, another Geico insurance agent called me and told me they have open my claim number again for furthur investigation. I told them same thing I told the police and agent during the day of accident. Couple days later, the new geico insurance said the damage occured to the inner part of the door and it was both of our ( the girl and me ) fault and said I could have 2-3 second to brake my car. So my policy have to pay 50% of the repair fee. My car is a old 98 crv and the damage is minimal but the girl's car is brand new and the whole door would have to be replaced I think. I would wait ultil Monday to ask the agent what cause them to think I could have 2-3 second to brake my car and how is the damage occured to the girls's car's inner door. Until now, I hope some one can give me some suggestions. Any suggestions would really be appreciated. Thank you.
