  "description": "A private seller (the current registered owner) and buyer (the new registered owner) transfer a Singapore-registered vehicle's registration through the Land Transport Authority's OneMotoring digital service. The seller initiates the transfer with the vehicle's particulars and the new owner's identity and contact details; the new owner then logs in with Singpass within 5 days to confirm, provide their own particulars and Singapore address, and declare valid motor insurance, before paying the transfer fee. Models an individual-to-individual transfer of a privately owned car. It does not model a transfer to or from a company/business/ACRA-registered entity, a vehicle still under financing (a separate multi-step confirmation cycle with the financier), a Light/Heavy Goods Vehicle or bus (which carry additional licence/parking-certificate requirements), vehicle-registration-number retention, or deregistration. It does not submit the notification; the live LTA source is always authoritative (see VERIFICATION.md).",

The live onemotoring.lta.gov.sg digital-service screens themselves are Singpass-gated and could not be exercised end to end without a genuine Singpass login; a mock application-packet test run (conformance/sg/lta/vehicle-ownership-transfer/1.0.0/application-packet.json) was assembled and checked against this schema's own required/requiredWhen/validation constraints instead of a live submission.
