Legal analysis: 1. After deducting the last month's mortgage payment, it will take about 10 working days to get back the mortgage formalities at the bank that handles the car installment payment. The bank's credit card car is in stages. It is best to call the bank's customer service phone in advance to ask if it has been completely settled. The customer service phone number can be found on the back of the repayment card. For car loans handled by financial companies, you can call the customer service phone number of your financial company or go to the car dealer for consultation.

2. To obtain a motor vehicle registration certificate, you must hold an ID card. Other possible procedures include: motor vehicle driving license, bank repayment details, etc.

3. After getting the registration certificate, the next step is to go to the local vehicle management office to handle the vehicle mortgage cancellation procedures. Materials to be brought together include: motor vehicle registration certificate, loan settlement certificate issued by the lending institution, lender organization code certificate, motor vehicle mortgage registration/pledge filing application form, power of attorney, and motor vehicle owner's ID card.

4. After going to the lobby of the vehicle management office, you can handle it at the corresponding service window.
