Can a co signer take the car and refuse to give it back enen though payment plan has been made with creditors?

The answer to this question depends on the specific laws and regulations in your jurisdiction. In general, a co-signer is someone who agrees to be legally responsible for a debt or obligation if the primary borrower defaults. This means that the co-signer is responsible for making payments if the primary borrower fails to do so. In some cases, a co-signer may also be entitled to possession of the car if the primary borrower defaults. However, this is not always the case, and the specific rights and responsibilities of a co-signer will vary depending on the terms of the loan agreement and the laws in your jurisdiction. It is important to consult with a qualified attorney in your area to determine your specific rights and responsibilities as a co-signer.
