What is a Flats Plan?
A flats plan is a key document registered on a cross lease title. It shows:
Think of it as the agreed map that defines what each cross lease owner can use exclusively. It's legally binding and any changes to building footprints must be reflected on the plan.
Why Flats Plans Matter
When you own a cross lease property, your ownership is based on two things:
1. A share of the freehold land (owned jointly with other cross lease owners)
2. A lease giving you exclusive right to occupy your dwelling as shown on the flats plan
This means the flats plan isn't just a diagram — it defines the physical extent of what you're entitled to occupy. If the building doesn't match the plan, there's a legal mismatch.

4. Neighbour Disputes
An unapproved alteration can trigger disputes with other cross lease owners who didn't consent to the changes.

*During due diligence, you discover the building doesn't match the flats plan.*
Best approach: Either require the vendor to update the plan before settlement, or negotiate a price reduction to cover the cost of updating it yourself.Scenario 3: Planning Renovations

How do I know if my cross lease title is defective?
Order your certificate of title and flats plan, then compare the plan to the actual building. Any mismatch in the building footprint means the title is defective.
Can I sell a property with a defective cross lease?
Technically yes, but it will likely reduce interest, affect the sale price, and may prevent buyers from getting finance approval.
How long does it take to update a flats plan?
Typically 2-4 months, depending on getting neighbour consent, surveyor availability, and registration processing times.
Do I need council consent to update a flats plan?
The flats plan update itself doesn't require council consent, but the building work that triggered the update may have needed building consent.
What if the alteration was done by a previous owner?
You inherit the defective title. The responsibility to fix it passes to the current owner, regardless of who made the changes.
Is it worth converting to freehold instead?
Often yes, especially if flats plan updates are needed anyway. Freehold titles are simpler to manage and generally more valuable.
