vehicle accident
I hope you can help me. My father in law is being sued. He had a dodge caravan 1993 in which the air bag deployed, and it cost more to fix it than the van was worth. so he did not fix it. He sold it in 2002, for $1600, and told the buyer about the air bag, but did not put it in writing. Well it has sold three more times to different owners, and the last owner since him, just got in an accident and of course the air bag did not deploy. so one of the owners between my father in law and the
last owners did not disclose the problem. Now, this owner has
called my father in law, and my father in law told him he had not repaired it. He must have contacted all of the previous owners. Now he says he is going to sue him, and that this is a felony. This is my first time at your website, I hope you can help. just need some info. I realize my father in law should have put this on the bill of sale, but he goes off of his word most of the time. the van is probably worth about $600 now.
thank you for your time. i really appreciate it

no insurance I had just bought a car and got pulled over and in getting pulled…

no insurance
I had just bought a car and got pulled over and in getting pulled over they found out that i had no insurance on the vehicle since i had just bought it less than an hour ago. They even talked on the phone with the guy i had bought the car from and said he had received partial payment but had not given me the title to the car yet. They still issued me an insurance ticket. It was also at night and all insurance places were closed. Shouldn’t i get 24 hours to get insurance on the vehicle. I also had a bill of sale in the car but the officer wouldn’t even let me talk to say that i had one. Is that right that i received the ticket?
