Can a co signer on an auto loan refiance without the other co signers signature?

My ex husband co signed for my daughter on an auto loan. His girlfriend was mad and he refianced the car with another bank and now he is the only one on the loan, title and regestration. I am quite sure that my daughter had to sign the title also and she did not. Either my ex did or his girlfriend did. He then showed up here yesterday and took that car. What is my recourse and where do I go from here? Per the original bank, she needed to sign the title also. Any help and advice would be greatly appreciated.

i would call you local dmv, then call the finace company and ask questionsHad she made any payments on the car? If so, the only thing that she is due is any amount of money payed for months that she could not use the car. So if she made a January payment but she could not drive the car, then she is due that amount. But being that her father is the cosigner, he is also the co-owner and has the right to take posession of the car and title it in his name.
who ever is on the loan has to sign off on loan and title unless she is a minor and it should have been notatized.good luck.
my wife and her co workers thay all work at a bank .
i dont think he could have done it without her signature. i would seek the girlfriend out and whip her
