Auto Repair Dispute Leads to Judgment for Unpaid 4000 Yuan Repair Bill with Guarantor Liability

Auto Repair Dispute Leads to Judgment for Unpaid 4000 Yuan Repair Bill with Guarantor Liability

Case Overview
A Chinese court ruled in favor of an auto repair shop owner who sought payment for a 4000 yuan repair bill. The defendant customer failed to pay the agreed amount and the guarantor was held jointly liable. The court ordered the customer to pay the principal plus interest at four times the bank lending rate, with the guarantor bearing joint liability.

Case Background and Facts
The plaintiff, Mr. Wu, operated a vehicle repair shop. On September 5, 2010, the defendant, Mr. Chen, brought a Geely sedan to the shop for repairs. After the work was completed, Mr. Chen owed 4000 yuan in repair costs. He issued a written IOU to Mr. Wu, promising to pay the full amount by September 15, 2010. The IOU also stated that if Mr. Chen failed to pay on time, he would bear interest at four times the bank lending rate. A second defendant, Mr. Wu (same surname as plaintiff but unrelated), acted as a guarantor for the debt. Despite repeated demands, Mr. Chen did not pay. Mr. Wu filed a lawsuit seeking repayment of the 4000 yuan plus interest at four times the bank rate.

Court Proceedings and Evidence
The court applied summary procedures and held a public hearing. The plaintiff appeared in court. Both defendants were properly served with legal summons but did not attend the hearing. The plaintiff submitted three key pieces of evidence: a customer settlement slip from the repair shop showing the 4000 yuan owed, the original IOU signed by Mr. Chen confirming the debt and interest terms and naming Mr. Wu as guarantor, and a court record of a conversation with Mr. Wu in which he confirmed his role as guarantor. The court found all evidence admissible and credible.

Court Findings and Judgment
The court found that the debt relationship between Mr. Wu and Mr. Chen was clear and legally valid. Mr. Chen had acknowledged the debt by signing the IOU and agreeing to the interest terms. The court held that both parties must honor their agreements and that Mr. Chen was obligated to pay the 4000 yuan plus the agreed interest. Regarding the guarantor, because the contract did not specify the type of guarantee, the court applied the relevant law to find that Mr. Wu assumed joint and several liability. The court ordered Mr. Chen to pay the principal of 4000 yuan plus interest at four times the bank lending rate from September 15, 2010 until the date of full payment. Mr. Wu was ordered to bear joint liability for this amount. The court also ordered Mr. Chen to pay court costs of 50 yuan. If payment was delayed, additional interest would accrue.

Key Legal Principles
This case illustrates that a valid IOU creates a legally enforceable debt obligation. When a debtor fails to pay, the creditor may seek court enforcement of both principal and agreed interest. Under Chinese law, if a guarantee contract does not specify the type of guarantee, the guarantor is presumed to assume joint and several liability, meaning the creditor can demand payment from either the debtor or the guarantor directly. The court also applied the principle that parties must perform their contractual duties in good faith.

Practical Insights
This case demonstrates the importance of obtaining written documentation of debts, such as an IOU, which can serve as strong evidence in court. Including a guarantor in a debt agreement can provide additional security for the creditor. However, guarantors should understand that if the guarantee type is not specified, they may be held jointly liable. The case also shows that courts will enforce reasonable interest terms agreed upon by the parties, including rates up to four times the bank lending rate.
