If you owe money and don't pay back, you need to analyze the specific situation. If you don't pay back the money you owe, it violates the law of creditor's rights and debts. If the borrower fails to repay the arrears, it shall pay the interest and overdue interest according to laws and regulations and the contract. If the borrower still refuses to repay the loan, the lender may bring a civil lawsuit to the court. If hitting a person constitutes a minor injury standard, it will bear the corresponding criminal legal responsibility.
