What if it’s for someone who has passed away. Not for self as SingPass is required.

Hi Amy! To check vehicle ownership, please follow these steps:

Log in to the OneMotoring portal with your Singpass and access the "Enquire My Vehicle" service. This service allows you to view and download your vehicle details, including proof of ownership.

Hope this helps!
