Below is a very recent extract from the Landgate website:
Electronic conveyancing continues to progress in WA and nationally, providing a safer way for property transactions to occur. Having to produce a Duplicate Title for an electronic land transaction does not make sense. There are now safer ways to verify a right to deal on a Certificate of Title to record or register an interest in the land other than providing a Duplicate Title. As Duplicate Titles have been optional for over 25 years, we have been transitioning to this point for a long time including creating safer legal frameworks in the state and national electronic conveyancing networks and registration processes.
Duplicate Titles will no longer be issued or able to be used.
If you already have a Duplicate Title, it will no longer be a legal document. You can keep the document as a historical artefact and you do not need to return it.
The original Certificate of Title is the single source of truth. You can order a Record of Certificate of Title online and this provides the current ownership details as well as all registered interests and encumbrances for that land parcel.
The specific date this change will come into effect will be publicised closer to the time.
