WA Deposited Plans: A Guide for Property Buyers

Plain-English Answer

In Western Australia, land is described by reference to a deposited plan (DP), administered by Landgate. A deposited plan is prepared by a licensed surveyor, approved by the Western Australian Planning Commission where required, and lodged with Landgate to record a subdivision, boundary adjustment or new lot layout.

Since July 2000, all new freehold plans and diagrams in WA have been lodged and registered as deposited plans. Before that date, freehold subdivisions were lodged as Freehold Plans (prefixed P) or Freehold Diagrams (prefixed D), depending on the number of lots created. Landgate has since allocated many older Crown and freehold survey records a DP number as well, alongside their original reference, so plans from any era can generally be searched using a DP number today.

What the Document Can Show

A WA deposited plan shows the lot boundaries, dimensions and bearings, the total area of each new lot, and the parent lot or plan the land was created from.

It also shows any new easements created as part of the subdivision — for example, drainage easements benefiting the local council — along with the licensed surveyor's certification and the plan's approval and registration dates.

What It Cannot Establish

A deposited plan does not confirm where boundary pegs currently sit on the ground, particularly on older plans and diagrams where survey methods differ from current standards.

It also does not include WA planning scheme zoning, local government approvals, rates, or the condition of any building — those sit outside the plan and require separate WA planning and council searches.

Practical Next Steps

Locate your lot and DP number on your title record or rates notice, then, where available, order the plan through TitleNow to review the layout and any registered easements.

For owner-builder projects, it's worth reviewing the deposited plan alongside a current WA title search, since together they show both the registered ownership and the physical lot history behind it.

When to Seek Professional Advice

A deposited plan does not re-establish a boundary on the ground. If you need a boundary pegged or verified for a build, retaining wall or fence, engage a licensed surveyor registered in WA.

For advice on how an easement or plan notation affects a specific transaction, speak with a conveyancer or solicitor.
