if you are from 'merica
Yes.
Sue them, you have already taken pitty on them, so if they dont show signs of paying ( take your warning) sue them
Pay the loan off and then collect payments from the person you cosigned for.
No, you would have to redo the loan.
Unfortunately if you cosigned a loan that means you were willing to pay the loan if the other signer defaults and if that happen they will go by any means to collect that money that you "cosigned/said" you would cover if the other person defaults. I would go after that person that you cosigned for if it has gone this far.
Very little, you will have to pay.
If you made the payment, yes.
Yes.
He will be the first to be sued. You will be next. Make sure the lender knows where he is working and living.
Yes
only if you owe them money
If a person's name is listed on a title, that person owns the car. If a person merely cosigned the note, that person's name will not be on the title. If you own the car, you certainly can take physical possession of it.
