This is a compilation of guides and steps as these guides are also used in different scenarios.

2. Follow this guide (this is the same process for when a vehicle changes hands from one of you customers to another) http://service.autosoft.com.au/entries/21440305-How-to-Change-the-Ownership-of-a-Vehicle-Rego-to-Another-Debtor
