Lawsuit Over Unpaid Water Tower Debt Yields CNY 1,200 Judgment

All Real CasesMay 10, 2026 4 min read

In a recent civil dispute heard in an Eastern China City court, the plaintiff sought payment for water towers sold on installment terms. The court ruled in favor of the plaintiff on the principal amount but adjusted the interest rate after finding the contractually agreed penalty to be excessive. The case illustrates how Chinese courts treat default interest clauses that exceed legal limits.

The plaintiff, Mr. Wang, operated as a self-employed trader in Eastern China City. On January 22, 2011, he sold several water towers to the defendant, Mr. Li, on credit. Mr. Li issued a handwritten promissory note acknowledging a debt of CNY 1,500. The note stated that the full amount would be paid by the end of 2011, and that if payment was late, Mr. Li would pay interest at 5 percent of the outstanding balance per month. Later, Mr. Li returned two water towers worth CNY 300, reducing the unpaid amount to CNY 1,200. Mr. Wang made repeated requests for payment, but Mr. Li did not comply. Mr. Wang then filed a lawsuit demanding payment of the principal and the contractual interest.

The court accepted the case on January 9, 2012, and proceeded under summary procedures. A public hearing was held on March 6, 2012. Mr. Wang attended with his legal representative, while Mr. Li, although properly served with a summons, did not appear in court and offered no defense. The court therefore conducted a default judgment. The key evidence consisted of the promissory note dated January 22, 2011, as well as the hearing record. The court found that the note clearly established the debt and the terms. Because Mr. Li failed to appear, the court treated the plaintiff’s factual allegations as undisputed.

The court held that the relationship between Mr. Wang and Mr. Li was a sales contract with deferred payment, and that Mr. Li was liable for the unpaid balance. The court therefore ordered Mr. Li to pay the principal of CNY 1,200. Regarding interest, the court examined the contractual term of 5 percent per month. It concluded that this rate exceeded the scope of legal protection afforded to creditors. In accordance with relevant law, the court declined to enforce that rate and instead ruled that interest should be calculated at the rate for bank loans of the same period. Interest would run from January 1, 2012 until full payment was made. The court also ordered that if payment was delayed beyond the judgment deadline, an additional penalty of double interest would apply.

According to the Contract Law of the People’s Republic of China, specifically Article 109, a party that fails to pay the price or remuneration may be required to do so. Article 161 provides that a buyer must pay the price at the agreed time. Because Mr. Li did not pay as promised, he breached the contract. The court’s adjustment of the interest rate reflects a standard legal principle: courts will not enforce penalty clauses that are disproportionately high or that amount to usury. The statutory loan rate is considered a fair substitute. The court also applied the Civil Procedure Rule allowing default judgment when a defendant fails to appear without justification.

This case serves as a practical reminder that while Chinese courts will enforce commercial debts and written agreements, they will not automatically uphold extreme interest terms. Parties should ensure that any penalty or late-payment interest clause is reasonable and within legal guidelines, otherwise it may be replaced with the standard bank lending rate. Defendants who ignore court summons risk a default judgment against them, which can lead to enforcement actions. The judgment here reinforces that clear documentary evidence, such as a promissory note, is highly persuasive in court.
