It sounds to me that, if by your calculation you have paid the value of the car and the company issued you a title you have a good claim to the car.
You mentioned that it was a lease
...if it was a leas to purchase option this will help you case, but if not, they have an argument that there was a mistake and that the court needs to correct
The law will allow the court to correct an honest mistake...so for example, if you had a lease for 5 years and were required to return the car after 5 years and after 1 year a clerk at the company made a mistake and sent you the title, the company would likely be able to get the court to force you to return the title.
But, if you had a contract
to purchase the car at the end of the lease and now you paid the proper amount and have the title...well your case becomes much stronger
I would read the summons very carefully...it will have the complaint on it and will give you some good insight into the case.
BotXXXXX XXXXXne...if this was an honest mistake by Chrysler, they will likely win. But they have to prove it.
