first of all. acting out like that will always come back to you. so i advise you to never do anything like that again, it will definatly catch up with you. But about your ex, if this happened almost a year ago and the car was in his fathers name, it doesnt look good for you ex. 1- because it happened almost a year ago, and he's waiting until now to do anything. 2- if the car was in his fathers name, i believe that his father will have to take action, because he will have to prove that otherwise. But i could be wrong abou that part. But i wonder what is the evidence against you? How exactly is he going to prove that you keyed the car. especially after so long? Make sure that you make it clear to the jugde that you believe that he is doing this because he is angry that the child support was raisd. good luck. If it is proven that you are guilty, you will probably have to pay. I wonder why he did'nt do anything until now?
