If you cannot submit a NOD online, you can submit a paper NOD to Service SA instead.
A paper copy of the NOD is on the back of a vehicle's registration certificate (this is sent to you with your paper or digital renewal notice).
Both the seller and buyer must sign the NOD.
If you don't have your registration certificate, you can apply for a replacement or complete a notice of disposal (87.2 KB PDF) (106.6 KB PDF) application form.
In person
Take the completed NOD to any Service SA centre.
Post
Send the completed NOD to:

GPO Box 1533
