A man in Zhejiang, China was left stunned after discovering that the apartment he had spent around 200,000 yuan (approximately RM122,230) renovating actually belonged to his neighbour.
The mistake only came to light six months later when he was preparing to move in, revealing a costly error that had gone unnoticed for months.
According to reports by ETtoday, the confusion stemmed from a developer’s mistake during the handover process, where unit numbers were incorrectly fixed on the apartment doors.
The man’s designated unit, 104, had been wrongly placed on the door of unit 103, which belonged to his neighbour. As a result, he proceeded with renovations without realising he had entered and upgraded the wrong property.
General real estate errors of this nature are rare but can lead to serious financial and legal disputes, especially when identification systems and verification processes are not strictly followed.
He reportedly failed to double-check the official floor plan and unit details, as both apartments shared a similar layout, further contributing to the confusion.
Angered by the incident, the homeowner demanded compensation, but all parties failed to reach an agreement on liability and the amount of damages to be paid.
The matter was later taken to court, with the owner of unit 104 filing a lawsuit against the property developer and naming the management company as a co-defendant, while the occupant of unit 103 was listed as a third party.
The court ultimately ruled that the developer bore primary responsibility for failing to properly verify property details during the handover process.
The property management company was also found negligent for not detecting the error during inspections and the official transfer procedures.
The case highlights the importance of strict verification in property development and handover processes, particularly in high-density residential projects where unit identification errors can result in significant financial losses.
