The decompression truck must be in the place where it was originally allowed. Generally speaking, vehicle decompression must be handled at the licensed local vehicle management office, and I will go there myself, because the vehicle files used for vehicle decompression are also at the licensed local vehicle management office. The procedures needed to decompress the vehicle are as follows: after deducting the last month's mortgage payment, you can get back the mortgage formalities at the bank that handles the car installment payment in about 10 working days. To get a motor vehicle registration certificate, you must hold an ID card. Other possible procedures include motor vehicle driving license and bank repayment details. After receiving the registration certificate, the next step is to go through the formalities of vehicle mortgage cancellation at the local vehicle management office. The materials that need to be brought together include the motor vehicle registration certificate, the loan settlement certificate issued by the lending institution, the lender's organization code certificate, the motor vehicle mortgage registration/pledge filing application form, the power of attorney, and the motor vehicle owner's ID card. After going to the lobby of the vehicle management office, you can handle it at the corresponding service window.
