Car sale without transfer of title
I sold my car on Ebay to a private party. The other party took possession of the car soon after the sale. I gave the other party a completed bill of sale and notified the DMV of transfer of ownership. I cashed their check but have not paid off the car loan yet. They have not received the title for the car. Now a detective is attempting to contact me to ask questions about the sale. The detective is harassing my family at their places of business and other employees that work for them. He says he realizes this is a civil matter but want to talk to me before it becomes a criminal matter. My question is can this become a criminal matter or would it remain a civil matter?

What to do?

What to do? Pulled over for not having insurance.
To make a long story short when I drove my car to go get registered and get insurance I was pulled over. I got a citation for not having insurance. After this experience, I decided that it would be best to just get rid of the car. So I am selling it. However I still have to go to court regarding my lack of insurance. My question is: would it be better to walk into court with a notarized bill of sale, or 2. get insurance for a couple of days and then cancel it after going to court, or 3. get both? I would rather not spend $100 on insurance for a couple of days as well as the fine, but will do what I have to.

car sold and not taken out of my name.

car sold and not taken out of my name.
I sold a car to someone shortly after purchasing it. They never registered the car in their name. Then this person was involved in a hit and run accident. I now am held accountable for all the fees and the injured parties expenses. I am also not able to register my current car and my license was suspended due to failure to pay the fines. I no longer have the bill of sale. Is there anything I can do about this?

Theft?
