What due diligence actually means before you buy land

Most land disputes are not accidents. They are the predictable result of a purchase that closed before anyone confirmed what was actually being sold. The paperwork looked complete, the seller was convincing, and the price was good enough that asking a fourth question felt like bad manners.

Due diligence is not a document. It is a sequence, and the order matters, because each step tells you whether the next one is worth paying for.

Start with the root of title

Every parcel has a chain of ownership running back to an original grant. The question is not whether the seller holds a document — it is whether the document they hold was validly issued by someone who had the right to issue it, and whether every transfer since then was properly executed and registered.

A gap anywhere in that chain is a gap you inherit. It does not matter that the break happened three owners ago; you buy the defect along with the land.

Then confirm the land is not encumbered

• A registry search reveals whether the parcel is already mortgaged, charged, or subject to a caution filed by a third party.
• Government acquisition is the one most buyers miss — land under a committed public scheme cannot be freely sold, whatever the seller says.
• Existing litigation over the parcel will not appear on any document the seller volunteers. It has to be searched for.

Verify the physical parcel, not just the file

A survey plan describes a specific piece of ground with specific coordinates. Confirming that the plan matches the land you were shown — and that neither overlaps a neighbouring claim — requires a surveyor on site, not a document review in an office.

The cheapest stage to discover a problem is before the money moves. Every stage after that costs more, and the last one costs a courtroom.

Understand what you are permitted to build

Clean title tells you the land is yours. It does not tell you that the scheme you have in mind is achievable on it. Zoning, setback requirements, density limits, and drainage constraints all shape what the site can actually carry — and they are worth knowing before you own it rather than after.

Why we run this before every acquisition

Tilden sits inside a group that handles land, design, construction, and long-term management. That structure only works if the first step is sound. A title problem discovered during construction does not stay a title problem — it becomes a delivery problem, a buyer problem, and eventually a reputation problem.

So we resolve it first, in full, every time. It is slower at the start and considerably faster everywhere else.
