When you order a property title in New Zealand, one section can confuse even experienced buyers: the legal description. It's a string of terms like "Lot 12 DP 558932" or "Flat 3 DPS 87421" that looks like code — but every word matters. Misunderstanding your legal description can lead to ordering the wrong title, missing encumbrances, or buying a property that isn't what you think it is.
This guide decodes every part of a New Zealand property title legal description so you can read it confidently and know exactly what you're looking at.

What Is a Legal Description?
A legal description is the formal, unique identifier for a parcel of land or unit recorded on the New Zealand land register. It's not the street address — it's the official reference used by the land registration system to precisely identify what's being transferred, mortgaged, or searched.
Every Record of Title in New Zealand includes a legal description in the "Estate" or "Legal Description" field. When you order a Record of Title with Diagram ($42.90), the legal description links directly to the survey diagram showing your property's boundaries.

The Building Blocks of a Legal Description
Lot and Deposited Plan (DP)
The most common format you'll see is:
> Lot 12 DP 558932
Here's what each part means:
| Component | Meaning | |-----------|---------| | Lot | A specific numbered area of land within a subdivision plan | | 12 | The lot number — uniquely identifies this piece within the plan | | DP | Deposited Plan (also called a subdivision plan or survey plan) | | 558932 | The plan number — every subdivision has a unique DP number filed with the land register |Together, "Lot 12 DP 558932" means: the 12th lot in deposited plan number 558932. No other property in New Zealand has this exact combination.
Flat and Deposited Plan (for Unit Titles)
For apartments and townhouses under the Unit Titles Act, you'll see:
> Flat 3 DPS 87421
- Flat 3 — Unit number 3 within the development - DPS — Deposited Plan Stage (the unit title subdivision plan) - 87421 — The plan numberIf you see "Flat" or "Unit" in a legal description, you're dealing with a stratum estate or unit title. Always order a Guaranteed Search ($45.90) to check for body corporate obligations and unit entitlements.
Section and Survey District (SD)
For older subdivisions, particularly in provincial areas, you might encounter:
> Section 15 Block V Otamatea Survey District
- Section — A numbered area in an older subdivision (pre-DP system) - Block V — A block within the survey district - Otamatea Survey District — The geographic survey districtThese descriptions reference the original Crown grant subdivisions and are still valid and legally binding. The key difference: Sections use Survey Districts, while Lots use Deposited Plans.

Other Legal Description Terms You'll Encounter
Allotment (Allot)
> Allotment 7 Parish of Tamaki
Used in very old titles, particularly for Māori land and early Crown grants. An allotment is similar to a lot — a defined portion within a parish (a historical land division). If you're researching historical ownership, a Historical Title ($42.90) will reveal the original grant details.
Area and Area Unit
> Area A SO 458732
"Area" is used for larger land parcels that aren't subdivided into lots. "SO" stands for Survey Office plan — the predecessor to DP. These are common in rural and lifestyle block titles.
Maori Freehold Land
> Te Ture Whenua Maori Act 1993 — Section 145
Titles for Māori freehold land have legal descriptions referencing the Te Ture Whenua Māori Act. These titles have special rules around alienation and management. If you're looking at Māori freehold land, a Legal Owner Search ($65.90) can help identify all registered owners, as these properties often have multiple shareholders.
Covenant Areas
> Area A DP 487231 (Subject to Covenant)
Some legal descriptions include covenant references directly. This tells you that restrictions exist on the land use — common in new subdivisions where developers impose design covenants, building height limits, or single-dwelling requirements. For more on this, see our guide on How to Check for Covenants on a Property in NZ.

How Legal Descriptions Differ by Title Type
Fee Simple (Freehold)
> Lot 45 DP 378291
Simple and straightforward. One lot, one plan, one owner (or joint owners). This is the most common title type in New Zealand and the easiest legal description to interpret.
Stratum Estate (Unit Title)
> Flat 5 DPS 891234 plus Accessory Unit A DPS 891234
More complex because the principal unit (the apartment) is listed separately from accessory units (carpark, storage). You need to check both parts. The body corporate's rules and financial obligations are tied to the unit entitlement shown on the title.
For a complete explanation of this title type, see What Is a Stratum Estate Title in New Zealand and Unit Titles in New Zealand.
Cross Lease
> Flat 2 DP 478293 and Estate in Cross Lease being an undivided 1/3 share in the fee simple in Lot 1 DP 478293
Cross lease legal descriptions are the most complex. They describe two things simultaneously: your leasehold interest in the flat AND your share in the underlying freehold land. The cross-lease structure means all flat owners collectively own the land and lease their individual flats to each other.

Why Your Legal Description Matters
1. Ordering the Right Title
If you give the wrong legal description when ordering a title search, you'll get the wrong property's records. Always double-check the legal description on the sale and purchase agreement against the property listing and council records.
Tip: When ordering through our site, you can search by title reference (e.g., WN43C/782) or by legal description. If you're unsure, a Record of Title with Diagram ($42.90) includes the survey plan that visually confirms you've got the right property.
2. Identifying Title Type at a Glance
The legal description immediately tells you what kind of title you're dealing with: - Lot + DP → Most likely fee simple (freehold) - Flat/Unit + DPS → Stratum estate (unit title) - Cross lease language → Cross lease title - Section + SD → Older freehold title - Area + SO → Rural or lifestyle block
3. Checking for Subdivisions and Mergers
If a property has been recently subdivided, the legal description will change. What was "Lot 1 DP 558932" might now be "Lots 1-5 DP 601234" (the new subdivision plan). A Historical Title ($42.90) shows previous title references, helping you trace the property's history.
4. Verifying Boundaries
The DP number in your legal description links to a survey plan that defines your exact boundaries. Ordering a Cadastral Survey Plan ($49.90) gives you the official boundary document. For more on this, see our guide on How to Find Property Boundaries in New Zealand.

Common Mistakes When Reading Legal Descriptions
❌ Confusing Lot Number with Title Reference
A title reference (like WN43C/782) is the unique identifier for the title itself. A legal description (like Lot 12 DP 558932) identifies the land. They're different numbers for different purposes. One title can cover multiple lots, and one lot can be split across multiple titles after subdivision.❌ Ignoring "Subject To" Clauses
Legal descriptions sometimes include "Subject to" conditions: - Subject to covenant — restrictions on land use - Subject to easement — rights granted to others over your land - Subject to lease — someone else has a registered leaseThese are binding. Always read the full legal description, including any "Subject to" text.
❌ Missing Accessory Units
On unit titles, if the legal description only lists the principal unit and not the carpark or storage, those accessory spaces may not be included in your purchase. Verify that all units you expect are listed.❌ Assuming All DPs Are Current
A DP number might be historical — the land could have been re-subdivided under a new DP. The title's legal description should reference the current plan, but if you're looking at older documents, the DP reference might be outdated. Always order a current Record of Title with Diagram ($42.90) to get the latest information.---
Frequently Asked Questions
What if my legal description doesn't match the sale and purchase agreement?
This is a red flag that needs immediate investigation. The legal description on the title must match the agreement. Discrepancies could mean the seller is offering a different piece of land than what's on the title, or that a recent subdivision hasn't been properly registered. Contact your conveyancer and order a current Record of Title to verify.Can a property have more than one legal description?
Yes. If a property spans multiple lots (e.g., "Lots 12 and 13 DP 558932"), it will have multiple legal descriptions within one title. This is common for larger residential properties or properties that have been merged. Each lot still links to the same title reference.What does "CT" mean on property documents?
"CT" stands for Certificate of Title — the historical term for what's now called a Record of Title. You might see references like "CT WN43C/782" on older documents. These still refer to the same land registration system; the terminology changed when New Zealand moved to computerised titles, but the title reference format remains valid.---
