A land surveyor connects three things: the documents that describe land, the physical land on the ground, and the official record used by government, buyers, lenders and other professionals.
For a land buyer, this usually begins with a simple question. Where exactly is the land I am buying?
The title deed may give you a parcel number and an area. A Registry Index Map may show the parcel among neighbouring parcels. A seller may point out a fence, road or set of beacons. The surveyor works out how those records relate to the actual ground.
What happens during a land survey
The work normally starts before anyone arrives on site. The survey team reviews the available records for the parcel. Depending on the type of land and survey system, these may include the title or lease, Registry Index Map, deed plan, survey plan, mutation records, previous survey computations and other cadastral information.
The purpose is to understand how the parcel was originally defined and what evidence should exist on the ground.
The survey team then visits the site. Existing beacons, occupation lines, fences, walls, roads, buildings and other relevant features are identified and measured. Those measurements are compared with the survey records.
This allows the surveyor to answer practical questions such as:
- Does the land on the ground correspond with the parcel shown in the records?
- Are the boundary marks still in place?
- Does the existing fence follow the parcel boundary?
- Has a neighbour built across the recorded boundary?
- Is the access road where the records show it?
- Does the measured area make sense when compared with the cadastral information?
Where necessary, boundary positions can then be recovered or re-established using the available survey evidence and the applicable cadastral procedure.
The output depends on what the client is trying to do. A buyer may only need boundary verification before completing a purchase. A developer may need a topographical survey showing levels, buildings, roads and other site features. A subdivision requires new parcel boundaries and cadastral records. An apartment development may require a sectional plan. A wayleave or easement may require a surveyed corridor showing exactly where the right passes through the affected land.
So a survey is not one single product. The survey work depends on the land question being answered.
Buying land
Suppose you are buying a quarter-acre plot. You have seen the title. You have visited the land. There is a fence around it.
The important question is whether the fence, title and cadastral record are describing the same piece of land. This is one reason buyers commonly ask for boundary verification before completing a transaction. The surveyor reviews the parcel records and compares them with what exists on the ground.
A Registry Index Map is therefore useful for identifying parcels, but it should not automatically be treated as an exact construction drawing. Before building a wall or other permanent structure, the boundary should be properly established from the relevant survey evidence.
Buying part of a larger parcel
Now assume someone owns five acres and agrees to sell you one acre. The seller may be able to show you approximately where that acre will be. But that one acre is not yet a separate registered parcel.
The original parcel has to be subdivided. The proposed subdivision first goes through the relevant planning process. Once approved, the survey work translates that approved subdivision into actual parcel boundaries. The new parcels are measured, marked and documented for the cadastral process.
The Land Registration Act then requires the new subdivisions to be registered before a portion of the original registered parcel can be transferred separately.
This is the practical difference between being shown the acre you are buying and buying a legally identifiable parcel capable of having its own registered interest.
Subdividing your own land
The same process applies when a landowner wants to divide land for sale, inheritance or development. Suppose you own two acres and want four plots.
The first question is whether the proposed layout satisfies the planning requirements. That is a planning function.
The surveyor then takes the approved subdivision and establishes the new parcels on the ground. Measurements are made. The new boundaries are defined. Survey records are prepared. The cadastral record is updated through the applicable survey and registration process.
The county planning approval and the cadastral survey therefore perform different functions. One approves the proposed arrangement of land. The other defines the resulting parcels spatially and creates the survey information needed for the land-registration system.
Boundary disputes
Surveyors are also commonly called when neighbours disagree about a boundary. The visible fence is not automatically the legal boundary. Neither is a hedge, wall, row of trees or point shown on a mobile mapping application.
The surveyor begins with the records. The existing cadastral information is examined and compared with the physical evidence on site. Old beacons may be recovered. Neighbouring survey marks may help reconstruct missing evidence. Measurements can then be compared with the original survey information.
The Land Registration Act gives the Land Registrar an important statutory role in determining and fixing registered boundaries. The surveyor provides the spatial and technical evidence used in that process. This is why boundary work involves both the physical ground and the land-registration record.
Sectional property and apartments
Survey work is not limited to open land. It also appears inside buildings. Under the Sectional Properties Act, an existing building can be divided into separately owned units through a sectional plan prepared by a surveyor from a building plan approved by the county government.
An architectural drawing and a sectional plan perform different jobs. The architectural drawing describes the building. The sectional plan defines the units and common property for the land-registration system.
Once the sectional plan is registered, separate registers can be opened for the individual units. For someone buying an apartment, the survey work helps define precisely what property interest is being registered.
Easements and wayleaves
Land rights can also cross land rather than divide it. A water pipeline may pass through several parcels. A power line may require a wayleave. A landlocked property may require an access easement.
In each case, somebody must establish where the right begins, where it ends, how wide it is and which parcels it affects. That is a spatial problem. Survey measurements provide the geometry used to describe that right.
Where a surveyed plan becomes part of a legal instrument affecting rights or interests in land, the Survey Act becomes relevant.
What should a buyer ask for?
The right survey service depends on what you are trying to establish.
- Buying an existing parcel: You may need boundary verification.
- Buying part of a larger parcel: You are dealing with subdivision.
- Planning construction: You may need boundary verification and a topographical survey.
- Buying or creating units within a building: Sectional-property survey work may be required.
- A road, pipeline, drainage route or utility corridor crosses the land: You may be dealing with an easement or wayleave survey.
The useful starting point is therefore not “How much is a survey?” It is “What am I trying to establish or change about this land?” From that, the required records, fieldwork, approvals and survey outputs can be identified.

Send the parcel number or location, and what you plan to do with the land. A licensed surveyor reads it and replies by the next business day with the survey work that answers your question.
