Typically, the primary owner is responsible for making the loan payments and maintaining the vehicle. If the primary owner defaults on the loan, the co-signer may be required to make the payments or repossess the vehicle. However, the co-signer does not usually have the right to take possession of the vehicle simply because they have not made any payments.
If the co-signer wants to take possession of the vehicle, they may need to take legal action to do so. This may involve filing a lawsuit against the primary owner or going through a repossession process. The specific process will vary depending on the laws of the state where the loan was made.
It's important to note that the rights and responsibilities of co-signers can vary significantly from one loan agreement to another. Therefore, it's always a good idea to carefully read and understand the terms of the loan agreement before co-signing a loan.
