Write-off of credit card bad debts refers to the act of identifying bad debts and accounting treatment of qualified credit card loans according to the prescribed procedures. Credit card bad debts are due to the long overdue period, and banks collect unformed debts. Bad debts do not mean that there is no need to repay debts. Cardholders' debts will still be penalized, and all debts to be repaid must be paid off. If the repayment is not made in time, the bank will bring a lawsuit to the court. Once the borrower loses the case, the property under the personal name will be frozen, and then the auction proceeds will be returned to the bank under the supervision of the court. Consequences of non-repayment of loans: 1. If it is really unable to repay, it shall negotiate with the lending institution to extend the repayment period or repay it in installments; 2. If the lending institution fails to perform the judgment of the court within the performance period after suing the court and winning the case, it will apply to the court for enforcement; 3. When accepting enforcement, the court will inquire about the real estate, vehicles, securities and deposits under the name of the lender according to law; 4. If the lender refuses to perform the effective judgment of the court because there is no enforceable property under his name, negative information such as overdue repayment will be recorded in the personal credit report, which will restrict high consumption and entry and exit, and may even lead to judicial custody. Bad debt refers to the long-term overdue credit card, and later changed the contact information, home address and work unit, which led to the bank being unable to find the cardholder to collect the arrears, so the long-term outstanding credit card arrears became bad debts.
