Repossessing a car

If the car is solely in your husband's name and the loan is in your husband's name, then you need to take the vehicle back.  Purchasing or leasing a car for someone else can lead to a lot of problems down the road legally if the driver gets into a car accident.  The insurance company may decide it was fraudulent to have someone else driving the car as the "owner" when the true owner doesn't possess the vehicle.

You can consider also if the loan was done fraudulently (your husband thought he co-signed), then you may wish to contact the agency in your state who regulates the dealership -- the Illinois Dept of Financial and Professional Regulation.
