According to NSW Land Registry Services (2020) "a plan may be lodged in NSW LRS as a deposited plan redefining a parcel so as to include accreted land or title ad medium filum. A deposited plan may also be lodged redefining the original boundaries of a parcel to show the correct dimensions and area of the land."
So the team came across an unsuual plan of redefinition where it redefined a historic deposited plan and the existing Strata Plan retained its legal description. We contacted NSW Land Registry Services for clarification and their advice was quicker than expected!
In summary this is how I think we will process the plan of redefinition:
The plan of redefinition doesn't appear to affect property and rating side, so property records wouldn't change. What is complicated is trying to figure out the internal process in Council's Property and Rating System when there is no procedure or guidance on what should be done.
Within Council's Property and Rating System the plan of redefintion will be created from the historic DP, then the existing Strata Plan will be disassociated from the historic DP. Then the newly created Land Parcel will be associated with the existing Strata Plan. Now what to do with the property and rating records? Some form of inheritance from the historic DP i suppose?
