There is no mandatory requirement to handle the car mortgage in person or entrust others to handle it. As long as the agent handling the vehicle mortgage has the relevant entrustment certificate and the original ID card of the lender, he does not need to be present, and the agent can handle the vehicle mortgage loan on his behalf.
Of course, if I have time, I'd better handle the business myself. After all, subsequent users still need to go through mortgage cancellation procedures, and I can know some procedures in advance when handling business. Or the lending institution stipulates that the vehicle mortgage loan must be handled in person, then it is impossible to authorize others to handle the business.
