Generally speaking, the vehicle loan needs to be detained in the Green Paper (Vehicle Register). Without the Green Paper, the vehicle cannot be transferred. If it is a private transaction, the original owner can't repay the car loan on time, and the bank or financial institution will apply to the court to detain the car as a lien on arrears. If the payment cannot be made within the time specified by the lender, the vehicle will be auctioned to repay the loan.
