Lot and Plan Numbers: Why They Matter in a Property Search

Lot and plan numbers are legal parcel identifiers used to connect a piece of land with its registered plan and title record. They are more precise than a street address and are especially useful where one address contains several legal parcels.

What does the lot identify?

The lot identifies the particular parcel within a registered plan. The plan reference identifies the survey or subdivision record in which that parcel was created or defined.

Why they matter for title searches

Using the correct lot and plan helps reduce the risk of ordering a title for an adjoining parcel, common property, car space or another lot at the same address. Plan prefixes and terminology vary by jurisdiction.

Where can you find lot and plan details?

They may appear on a contract, existing title search, council or property records, registered plan or property-search result. Always compare the identifiers across documents where accuracy matters.

A plan does not physically mark your boundary

A registered plan can show legal parcel information and survey details, but it does not by itself re-establish the boundary on site. A licensed cadastral surveyor is required where the physical boundary position matters.

Frequently asked questions

Is a lot and plan the same as an address?

No. It is a legal parcel identifier.

Can a plan show the exact boundary on the ground?

It records parcel information; a cadastral surveyor physically re-establishes boundaries.
