My husband was involoved in a 4 wheeler accident at a friends house in which he hit a neighbors car port post. The people who lived there at the time say that he hit their car instead. They did not file a police report at the time of the accident, and keep harassing us over the phone that we need to pay them for the damages done to their car. They only seem to be calling late at night and on my husbands work cell phone. It has been over a month and they keep threatening us that they are going to take us to civil court. They don't live in the house anymore where the accident happened because they got evicted, and all the cars have been moved.Can they file a claim without any proof, and are we liable to pay them if they don't have police report.
