Some people who face grand theft auto charges are not guilty of that crime. Possible defenses to these charges include: The car owner permitted you to use their vehicle. You had reason to believe that you could use the vehicle. Perhaps the owner loaned it to you in the past and you had access to the keys. You admit that you used the vehicle, but you intended to return it to the owner. You needed the car because of an emergency, such as if you had to drive someone to the hospital. You were under duress when you stole the car. For example, someone forced you to steal it through violence or threats of violence. The person who said you could use the car was not the rightful owner. You thought the car was yours. For example, a valet gave you the wrong car and you didn’t realize it at first. Your attorney can notify the court of your defenses for grand theft auto. This may result in dropped charges or reduced charges.
