Does this violate the uniqueness of the signature and does the contract have legal effect?
You are in trouble. You must read clearly the loan amount and interest rate in the loan contract. Penalty interest, etc. The penalty interest of general car loans is very high. At the same time, be sure to sign the contract in your own hands to prevent others from tampering. The high penalty interest of others has accumulated over time, which is very unfavorable to lenders. Generally, the car is equipped with GPS, which can locate the car and help you drive away. They won't take legal action for some time. If you go through legal channels yourself, the time will be longer. In the meantime, the penalty interest will still be on your head. If an electronic contract has been signed, I should also download the electronic contract in time and keep the voucher.
