Loan Repayment Dispute Over 80,000 RMB Between Former Partners: Court Rules on IOU Validity

CASE OVERVIEW

A civil lawsuit in Southern China involved a dispute over an 80,000 RMB loan between former romantic partners. The plaintiff, Ms. Wu, sought repayment of the loan based on a written IOU. The defendant, Mr. Gu, argued the money was from a joint lending business and that the IOU was signed under duress. The court ruled in favor of the plaintiff, ordering full repayment plus legal costs.

CASE BACKGROUND AND FACTS

Ms. Wu and Mr. Gu were previously in a romantic relationship. In 2007, Ms. Wu claimed that Mr. Gu borrowed money from her for his business operations. She stated that she lent him 50,000 RMB in September 2007 and an additional 30,000 RMB in October 2007, totaling 80,000 RMB. On February 15, 2008, Mr. Gu issued a written IOU to Ms. Wu confirming the debt. The IOU stated: “Borrowed 80,000 RMB from Wu Yan, eighty thousand yuan only.” Despite the written acknowledgment, Mr. Gu never repaid the amount.

Mr. Gu provided a different account. He argued that the 80,000 RMB was not a personal loan but money the couple had pooled together to lend to a third party at high interest rates during their cohabitation. When the third party defaulted and fled, the money was lost. Mr. Gu further claimed that Ms. Wu threatened to end their relationship unless he signed the IOU. He stated he signed only because he believed they would eventually marry. Mr. Gu provided no documentary evidence to support his version of events.

COURT PROCEEDINGS AND EVIDENCE

During the trial, Ms. Wu presented the original IOU as key evidence. Mr. Gu acknowledged the IOU was genuine and did not dispute its authenticity. The court accepted the IOU as valid evidence. Mr. Gu, however, failed to produce any evidence to substantiate his claims of duress or that the money was used for a joint lending scheme. The court noted that the defendant bore the burden of proof for his affirmative defenses but offered no supporting documents or witness testimony.

COURT FINDINGS AND JUDGMENT

The court found that a lawful creditor-debtor relationship existed between the parties. It held that debts must be repaid and that Ms. Wu’s claim for repayment was reasonable and legally sound. The court rejected Mr. Gu’s defense that the IOU was coerced, stating that without credible evidence, the claim of duress could not be accepted. Similarly, the argument that the funds were used for a joint high-interest lending venture was unsupported by any proof.

Pursuant to Article 206 of the Contract Law of the People’s Republic of China, the court ordered Mr. Gu to repay the full 80,000 RMB to Ms. Wu within seven days of the judgment taking effect. The court also imposed additional costs: if Mr. Gu failed to pay on time, he would be liable for double the interest on the overdue amount as stipulated by the Civil Procedure Law. Court costs of 1,800 RMB, reduced to 900 RMB, were assessed against Mr. Gu.

KEY LEGAL PRINCIPLES

This case illustrates the principle that a written IOU is strong evidence of a debt. Under Chinese contract law, a borrower who signs a clear, unambiguous IOU is generally obligated to repay. Defenses such as duress or alternative use of funds require substantial proof. The party raising such defenses bears the burden of production. Without evidence, the court will enforce the written agreement.

PRACTICAL INSIGHTS

Individuals entering into loan agreements with romantic partners should document the transaction clearly. A written IOU that states the amount, date, and parties involved is critical. Borrowers should understand that signing an IOU under pressure may still be enforceable if they cannot later prove duress. Both parties should keep records of payments and communications. If a dispute arises, timely legal action is important, as courts will rely on documentary evidence over oral claims.
