Court Rules on Unjust Enrichment Claim Over 306,000 Yuan Vehicle Sale Proceeds

Case Overview

A dispute over the proceeds from the sale of a heavy-duty truck led to a civil lawsuit in Eastern China, where the plaintiff sought the return of 306,000 yuan from a family member. The court examined whether the defendant had improperly retained funds that rightfully belonged to the vehicle owner. After evaluating evidence of payments and offsets, the court ordered the defendant to return 188,883 yuan, rejecting the full claim and clarifying the boundaries of unjust enrichment law.

Case Background and Facts

The plaintiff, Mr. Lv, owned a heavy-duty dump truck registered in his name. In 2010, he decided to sell the vehicle. Because he did not have a bank card at the time, he asked his cousin’s wife, the defendant Ms. Kan, to receive the sale proceeds on his behalf. Two buyers, Mr. Ma and Mr. Chen, agreed to purchase the truck for a total of 306,000 yuan. They made two payments to Ms. Kan’s bank account: 250,000 yuan before the vehicle transfer and 56,000 yuan after the transfer and registration process was completed.

After receiving the full amount, Ms. Kan refused to hand over the money to Mr. Lv. She claimed that the funds were not an improper gain but rather repayment for money she and her husband had previously lent to Mr. Lv for purchasing the truck. Mr. Lv denied this, asserting that the payments were unrelated to any prior debts. He filed a lawsuit demanding the return of the entire 306,000 yuan.

Court Proceedings and Evidence

The court held two hearings. The plaintiff presented documents showing he was the registered owner of the truck, including the vehicle purchase tax certificate, business license, and loan agreement. He also submitted the vehicle sale agreement and written statements from the buyers confirming they purchased the truck from him.

The defendant argued that she had provided substantial financial support to the plaintiff. She produced a receipt showing the plaintiff received 140,000 yuan from her husband, as well as bank transfer records for 91,500 yuan and 10,000 yuan. She also claimed she used 120,000 yuan from the sale proceeds to pay off the plaintiff’s bank loan on the truck and presented evidence of additional expenses, including 2,500 yuan for vehicle file transfer fees, 3,500 yuan for a worker’s wages, and 2,461 yuan for repair costs. She also sought to deduct 30,800 yuan for other expenses supported by receipts.

The buyers testified that they negotiated the sale with the defendant’s husband and paid the money to the defendant with the plaintiff’s knowledge and consent. They confirmed that the plaintiff was present during the vehicle transfer in Jiangsu Province.

Court Findings and Judgment

The court found that the plaintiff was the legal owner of the truck and that the sale proceeds rightfully belonged to him. However, the court rejected the plaintiff’s claim that the defendant had no right to any of the money. The court examined the defendant’s evidence and made specific findings.

The court determined that the defendant had used 108,656 yuan from the sale proceeds to pay off the plaintiff’s bank loan on the truck. This finding was supported by bank records showing withdrawals and deposits matching the loan repayment amounts, as well as the buyers’ testimony that the defendant handled the payment process. The court also accepted the defendant’s claims for 2,500 yuan in file transfer fees, 3,500 yuan in wages paid to a worker, and 2,461 yuan in repair costs, totaling 117,117 yuan in allowable deductions.

The court rejected the defendant’s attempt to deduct 30,800 yuan for other expenses because the receipts lacked sufficient connection to the plaintiff and were not supported by other evidence. The court also declined to address the prior loan disputes between the parties, stating that those matters involved a different legal relationship and were not part of this case.

The court held that Ms. Kan had no legal basis to retain the full 306,000 yuan. After subtracting the verified deductions of 117,117 yuan, the court ordered the defendant to return 188,883 yuan to the plaintiff. The plaintiff’s claim for the full amount was denied.

Key Legal Principles

The court applied the principle of unjust enrichment under Article 92 of the General Principles of Civil Law. This principle requires that a person who obtains a benefit without a legal basis and causes loss to another must return that benefit. The court clarified that the burden is on the party claiming an offset to prove the legitimacy of the deductions. The court also emphasized that disputes involving different legal relationships, such as prior loans, must be resolved in separate proceedings.

Practical Insights

This case illustrates the importance of documenting financial transactions clearly when family members are involved in commercial deals. The plaintiff’s decision to use the defendant’s bank account without a written agreement created ambiguity. The court’s willingness to allow the defendant to offset proven expenses shows that courts will examine the economic reality of a transaction, not just the formal title. Parties should keep detailed records of all payments and reimbursements to avoid disputes over what belongs to whom. The case also shows that courts will not automatically award the full amount claimed if the opposing party can demonstrate legitimate offsets.
