CCB understands that your "co-borrower" means that when applying for a loan, those who apply for a loan together with the main borrower share the repayment responsibility. Therefore, co-borrower has the responsibility. If the main borrower fails to repay the loan on time, co-borrower needs to bear the corresponding repayment responsibility. If co-borrower fails to repay the loan on time, CCB has the right to take legal measures to recover the arrears. Therefore, before signing the loan contract, co-borrower needs to carefully review its repayment ability to ensure that it has the ability to repay on time. At the same time, during the loan period, co-borrower also needs to pay close attention to the repayment of the loan to ensure timely repayment and avoid unnecessary economic burden and credit loss to itself and the main borrower.
