If you’re registering a new strata plan in NSW, there’s one survey you can’t skip, and most property owners don’t hear about it until they’re already mid-project. For many new strata developments, a Plan of Redefinition is required before a strata plan can be lodged with Land Registry Services. Getting it wrong or leaving it too late can stall your entire project.

What Is a Plan of Redefinition?
A Plan of Redefinition is a cadastral survey that legally re-establishes and redefines the boundaries of a parcel of land. It is used in a range of situations, including correcting boundary dimensions, providing survey definition for parcels that have never been formally surveyed, and resolving boundary uncertainty.
In the strata context, it acts as the base plan underlying the strata plan, establishing precise measurements, boundary positions, and legal descriptions for the parcel so that individual lots within the strata scheme can be accurately defined.
In cases where the existing base plan is found to be unreliable, outdated, or inadequate for the proposed strata development, a Plan of Redefinition is needed. Otherwise, a strata plan cannot be lodged with NSW Land Registry Services (LRS).
Why Does a Plan of Redefinition Exist?
NSW land titles are based on the Torrens system, which relies on precise cadastral records to define who owns what. Over time — through subdivision, consolidation, easement creation, or even accumulated survey error — boundary records can become inconsistent or outdated.
A Plan of Redefinition resolves those inconsistencies by re-establishing boundaries with current survey measurements, updated against the LRS cadastre. It creates a clean, accurate legal foundation that the strata plan can be built on top of. This protects all future lot owners within the strata scheme from inheriting a title based on imprecise boundary data.
When Do You Need a Plan of Redefinition?
A Plan of Redefinition is required in NSW whenever you intend to register a new strata plan. This applies to:
- New residential strata developments: apartments, townhouse complexes, villa projects
- Commercial strata schemes: office buildings, mixed-use developments, industrial strata
- Strata subdivisions on existing lots: where the parent parcel boundaries need to be reconfirmed before the strata plan is prepared
If your development reaches the stage where a strata plan needs to be lodged, a Plan of Redefinition must be completed and registered first, regardless of scale. The strata plan cannot proceed to lodgement until it’s in place.
Who Typically Needs One?
Plans of Redefinition are most commonly required by:
- Developers registering new residential or commercial strata schemes
- Builders completing multi-unit projects where strata title will be issued to individual purchasers
- Property owners subdividing or converting an existing property into strata lots
- Solicitors and conveyancers managing strata registration on behalf of clients
If you have a mortgage on the property, your lender also enters the picture. Before the Plan of Redefinition can be submitted to LRS, your mortgagee must review and formally endorse the plan. This step is often overlooked and can add time to an otherwise straightforward process if not arranged early.
How Does the Process Work?
The process typically follows these steps:
1. Engagement and brief: A surveyor reviews the existing title documents, deposited plans, and LRS cadastral data relevant to the parcel.
2. Site survey: The surveyor attends the site to physically locate and measure existing boundary marks, fences, and other reference features.
3. Plan preparation: Survey measurements are used to redraw and redefine the parcel boundaries in compliance with LRS requirements. The plan is drafted to survey standards.
4. Mortgagee endorsement: If a mortgage exists over the property, the plan is submitted to the lender for review and endorsement before lodgement.
5. LRS lodgement and registration: The completed, endorsed plan is lodged with NSW Land Registry Services for registration.
6. Strata plan proceeds: Once the Plan of Redefinition is registered, the strata plan can be prepared and lodged on top of it.
Most plans are completed within two to four weeks, depending on site complexity and how quickly mortgagee endorsement can be obtained. Delays in the mortgagee step are the most common source of extended timeframes. Build this into your project schedule early.
As a general guide, most Plans of Redefinition for standard residential development lots fall in the range of a few thousand dollars, with more complex sites or parcels with historic boundary uncertainty at the higher end. Always obtain a written quote that specifies what’s included and what isn’t.
Legal and Regulatory Context in NSW
Plans of Redefinition in NSW are governed by the Surveying and Spatial Information Act 2002 and the Surveying and Spatial Information Regulation 2024, administered by the NSW Surveyor-General. All plans must be prepared by a Registered Surveyor and comply with LRS lodgement requirements.
The survey standards that apply are detailed in the Surveyor-General’s Directions, which set out measurement accuracy requirements, mark placement obligations, and plan formatting rules. A non-compliant plan will be rejected by LRS, requiring corrections and re-lodgement. This adds time and cost to your project.
This is one area where choosing an experienced surveyor makes a direct difference to your timeline.
What Happens If You Don’t Get One?
The short answer: your strata plan can’t be registered. LRS won’t accept a strata plan without a registered Plan of Redefinition as its base.
Beyond the legal requirement, the practical risks of skipping or rushing this step include:
- Project delays: A rejected or incomplete plan pushes back your entire strata registration timeline, affecting settlement dates and cash flow
- Title defects: A strata plan built on imprecise or legally uncertain boundary data creates title risk that flows through to every lot owner in the scheme
- Lot allocation errors: Inaccurate base boundaries can result in incorrect lot dimensions and areas, which creates issues for both individual purchasers and building compliance
- Resale and financing complications: Buyers and their lenders will conduct title searches; boundary discrepancies or irregular plan histories can complicate sales and refinancing down the track
Frequently Asked Questions
Is a Plan of Redefinition legally binding?
Yes. Once registered with NSW Land Registry Services, a Plan of Redefinition forms part of the official NSW cadastre and is legally binding. It defines the boundary positions that underpin the strata plan and all lot titles created within it.
Will my neighbour be involved or notified?
In most cases, no — neighbouring landowners are not formally notified as part of the Plan of Redefinition process for a standard strata registration. However, if boundary positions are in genuine dispute, that’s a separate matter that may need to be resolved before the plan can proceed.
Can incorrect boundaries affect my property value?
Yes, materially. Title defects, uncertain boundaries, or historical discrepancies on a title can affect a property’s marketability, the ability to obtain finance against it, and its perceived value by buyers. A correctly prepared Plan of Redefinition removes that risk at the source.
What happens if I try to build without confirming my boundary?
For strata registration specifically, you won’t get past LRS; the plan simply won’t be accepted. For other build types, starting construction without confirmed boundary positions is a common cause of encroachment disputes, council compliance issues, and costly rework when set out has to be corrected mid-build.
Choosing the Right Surveyor for Your Plan of Redefinition
When selecting a surveyor for a Plan of Redefinition, the factors that matter most are LRS compliance experience, turnaround speed, and how well the surveyor manages the mortgagee endorsement process on your behalf. A slow or inexperienced surveyor doesn’t just cost you money; they cost you weeks on your programme.
Look for a firm with dedicated strata experience, a documented quality control process, and the capacity to manage LRS lodgement end-to-end rather than handing the paperwork back to you.
