Homebuyer Wins Refund of 1200 Yuan Water Meter Fee in Unjust Enrichment Case

Case Overview

A homeowner in Eastern China successfully sued a real estate development company for the return of 1200 yuan paid as a water meter fee during the handover of an affordable housing unit. The court found that the developer had no legal basis to charge this fee separately from the agreed purchase price. The developer was ordered to return the full amount plus interest calculated from the date of payment.

Case Background and Facts

In 2002, Mr. Xie signed a contract to purchase an affordable housing apartment from Zhejiang Economic Housing Development and Construction Company. The property was located in the Santang Lanyuan residential community in Eastern China. When the developer handed over the apartment in April 2003, it charged Mr. Xie 1200 yuan under the label of water meter collection fee. Mr. Xie paid this amount and received a special invoice for real estate sales.

Several years later in 2010, Mr. Xie learned from other homeowners in his community that the developer had been ordered by the provincial pricing authority to refund similar charges to other buyers. The provincial pricing authority had determined that the developer improperly collected this fee outside the approved sales price for affordable housing. Mr. Xie then demanded a refund from the developer, which refused. He filed a lawsuit in December 2010.

Court Proceedings and Evidence

The court held a public hearing in January 2011. Mr. Xie submitted evidence including the housing purchase contract, property ownership certificate, the 1200 yuan invoice, and a prior court judgment from a similar case involving other homeowners in the same community. The developer submitted construction drawings, price approval documents, engineering change orders, completion drawings, and cost verification reports to argue that the water meter system was an upgrade installed after the government had already set the housing price.

Both parties agreed on the authenticity of each others evidence but disputed its relevance. The developer claimed the 1200 yuan charge was justified because installing the smart water meter system cost over 1300 yuan per unit, and this cost was not included in the original government-approved price.

Court Findings and Judgment

The court identified two main issues. First, whether the developers collection of 1200 yuan constituted unjust enrichment. The court held that water supply facilities are basic infrastructure necessary for normal use of a home. The developer had a contractual duty to provide complete infrastructure. Since the purchase contract did not include any special agreement requiring buyers to pay separately for water supply facilities, the purchase price already covered the cost of such facilities.

The provincial pricing authority had already determined that the developer illegally collected this fee outside the approved affordable housing price, effectively raising the price. The court concluded the developer had no legal basis to retain the 1200 yuan and it constituted unjust enrichment.

Second, the court addressed whether the claim was barred by the statute of limitations. The developer argued more than two years had passed since payment. The court applied the rule that the limitation period for unjust enrichment claims begins when the claimant knows or should know of the enrichment and the obligated party. The developer failed to prove Mr. Xie knew or should have known the fee was improper at the time of payment. The court accepted Mr. Xies statement that he only learned of the unjust enrichment in 2010 when information about prior cases was posted in the community. The lawsuit filed in December 2010 was within the limitation period.

The court ordered the developer to return 1200 yuan plus interest at 5.76 percent per year from April 17, 2003 until full payment.

Key Legal Principles

Unjust enrichment occurs when a party obtains a benefit without a legal basis, causing loss to another party. The party receiving the benefit must return it. The limitation period for unjust enrichment claims starts from when the claimant discovers or should discover both the enrichment and the identity of the obligated party.

Practical Insights

This case demonstrates that developers cannot charge homebuyers for basic infrastructure costs that are already included in the purchase price. Buyers who pay such fees may have a valid claim for unjust enrichment. The statute of limitations for such claims does not necessarily start at the time of payment. It starts when the buyer actually knows or should know the charge was improper.
