If parents don't pay back the credit card arrears, their children's credit will not be affected. According to the law of China, debt settlement is only for the debtor.

Article 108 of the General Principles of the Civil Law stipulates: "The debt shall be paid off. If it is temporarily unable to repay, it may be repaid by the debtor in installments with the consent of the creditor or the ruling of the people's court. Those who have the ability to repay and refuse to repay shall be forced to repay by the people's court. " Therefore, it is certain that the debtor must repay the debt.

In practice, there are two different situations in which the debtor is unable to repay: one is temporarily unable to repay. If this is the case, it can be repaid by the debtor in installments in accordance with the relevant provisions of the above general principles of civil law. The other is permanent inability to repay. If it cannot be paid off permanently, it can only be paid off with the debtor's personal existing property.
