Parkrempler, what am I gonna do?

Hello to you, my father and I were on the road with the Volvo earlier and were driving a parking lot. At the parking lot my father wants to straight into the free parking bay. At the front right in the parking space there is a VW Golf next to us, which sits back and does not look back. We are firmly convinced that my father brought the car to stand before. The golfer then crashed accordingly with the fender and the tire into our bumper. The damage is Not a big one, except on a broken varnish with us and with the participant a slight dent in the fender. Since the golfer did not realize that he was unattentionally putting back and also was not ready to tell us his address and the insurance I called the police. After this had arrived everyone made his statement. I was a passenger with my father and then also made a statement. However, the other claimed in front of the officials that my father He fully cleanly And as it is, the police could not determine who is now the cause of the accident. Personalities were taken and the accident recorded. The police informed that all involved mail was received from the county and a fine was imposed. If the golfer is to blame, he must reckon with about 100 euros and 1 point. If my father is to blame, he must expect a fine of 20 – 30 euros. After the recording immediately went to the Volvo dealer. The report was sent to the police as a copy of the report. I would be pleased if someone knew the advice. Greetings Marius
