Deposited Plans in NSW: A Guide to DP Numbers

Plain-English Answer

In New South Wales, a deposited plan (DP) is the formal document registered with NSW Land Registry Services (NSW LRS) that defines the boundaries, dimensions and layout of a parcel of land. Most NSW properties are described by reference to a DP — for example, "Lot 23 in DP789678" — and that lot/DP reference appears on the title record. Since October 2021, NSW no longer issues paper certificates of title; the title is instead held electronically as a folio of the Register. Strata properties use a different format — for example, "Lot 1 in SP456" — referencing a strata plan rather than a deposited plan.

Deposited plans are prepared by registered surveyors and lodged whenever land is subdivided, consolidated, or has its boundaries redescribed. NSW LRS's numbering system has evolved over time — some historical plan series were renumbered into the DP sequence during the 1960s — but every current NSW title still traces back to a DP or SP number.

What the Document Can Show

A DP shows the lot boundaries, dimensions and bearings for each parcel included in the plan, the total number of lots created, and any easements, rights of way or restrictions registered as part of that plan.

It also identifies the registered surveyor responsible for the plan and the date it was lodged and registered, giving a clear record of when and how the current lot layout was created.

What It Cannot Establish

A deposited plan does not show current fence lines or structures, and it cannot confirm exactly where a boundary sits on the ground today — particularly on older plans, where survey methods and reference marks may differ from modern standards.

It also does not cover council planning controls, zoning, rates, flood or bushfire mapping, or the condition of any building on the land — these require separate NSW planning and council searches.

Practical Next Steps

Find your DP number on your title record or rates notice, then order a copy of the plan through TitleNow where available.

If you're planning a subdivision, boundary adjustment, or an owner-builder project close to a boundary, review the DP alongside a current title search so both the ownership details and the lot history are in front of you.

When to Seek Professional Advice

A deposited plan does not re-establish a boundary on the ground. If you need boundaries pegged or confirmed for a build, fence or dispute, engage a licensed surveyor registered in NSW.

For questions about how easements, covenants or restrictions on a DP affect a specific purchase or development, speak with a conveyancer or solicitor.
