A property title with a registration error, a flat plan that does not match the building, an unconsented improvement, or any other defect that limits saleability or registration. Common in older cross lease properties.
A defective title is a property title that has a registration error, a flat plan that does not match the actual building, an unconsented improvement that affects the registered footprint, or any other legal defect that limits saleability, registration, or financeability. Defective titles are most common in older cross lease properties, but they appear in fee simple titles too.
Plain-English example
A 1990s Henderson cross lease has three flats. The flat plan attached to the cross lease shows three identical building footprints. In 2010, the owner of flat 2 added a 12 square metre extension at the rear without updating the flat plan or getting co-owner consent. The cross lease title for flat 2 is now defective. The flat plan does not match what is actually on the ground.
When the owner tries to sell, the buyer’s lawyer pulls the title and the flat plan, compares them to the council file, and immediately spots the discrepancy. The buyer either walks away, drops the price, or asks the seller to fix the defect by updating the flat plan (which requires co-owner consent and a surveyor).
Why it matters
Defective titles affect price, finance, and saleability. Lenders sometimes refuse to lend on a property with an unresolved title defect. Insurers can decline cover or charge more. Buyers often walk away rather than buy a problem they will inherit.
Fixing a defective title typically requires a surveyor (to update the flat plan), the consent of co-owners (in cross lease cases), council sign-off on any unconsented work, and registration of the updated documents. The full fix can cost thousands of dollars and take months. It is much better to discover the defect before going to market than during a buyer’s due diligence.
Who needs to care
Anyone buying a cross lease property needs a careful title and flat plan check. Anyone buying an older fee simple property where the building has been altered needs to compare council records to the building. Anyone selling either type of property should run the same check before going to market and either fix the defect or disclose it.
Lenders and insurers care because defective titles affect their security and risk. Some lenders have policy exclusions for cross lease properties with unresolved flat plan defects.
What NZ Legal does for it
We run a title and flat plan check on every cross lease and on every fee simple property where the building has been altered. We compare the registered position to the council file and to the actual building footprint. We flag defects to the buyer in plain English.
If the defect is minor, we negotiate price adjustments or fix-it conditions. If the defect is material, we advise the buyer to walk away or condition the agreement on the defect being fixed before settlement. For sellers, we run a pre-listing title health check so they go to market with a clean position. Send us the title and we will tell you what we see.
