A clean title check has three layers. First, run the VIN through maintenance records: dealers in China log service visits with mileage, and gaps or mileage rollbacks are red flags.
Second, pull insurance claim history — major accidents, fire and flood damage usually leave claim records even if the car was repaired well. Third, verify registration status: confirm the car is not under finance, court seizure, or theft report.
From overseas, you can engage a local inspection agency or law firm to retrieve these records and issue a written report. Cross-check the VIN and engine number on the report against the registration certificate; any mismatch means walk away.
