So, from what I'm understanding, you agreed to give him the car for $4,000.00, but he never made any payment and took the car.
This may qualify a crime if he intended to steal the car from you. You can contact the police and report the vehicle stolen. I would explain to the police your situation though and make sure they understood that it was theft by trick and that you gave the keys to your ex.
Because you did in fact give the keys to him and enter into an agreement that he can have the car for $4,000 the police may tell you that you must handle this in the civil courts.
If this is the case, you will need to sue him for Conversion and Fraud and seek an injunction ordering him to turn the car over to you. This will not be a small claims
case and you will need to bring the case in the district court
. You will need an attorney to do this and you will need to be able to locate your ex.
If you are able to locate the vehicle and it is not locked away behind a fence, you may also have the vehicle towed to your house and have a locksmith change the locks on the vehicle.
Please let me know if you have further questions and please remember to rate my answer positively so that I am compensated for my work by the website.
