Boundary surveys: what they are for, how to read the plan

What a boundary survey does

Surveying a parcel means bringing in a licensed surveyor who measures
it, plants boundary markers (numbered concrete markers B1, B2, B3…) at
each corner, and draws up a survey report together with a
plan. The whole thing is stamped by the cadastral service.

Without a survey, the limits of a parcel are vague. That is the leading cause of
conflict between neighbours: everyone has “their idea” of where the line runs, and nobody
has proof.

Reading a survey plan

A serious survey plan always contains:

• the official letterhead (Ministry of State Property, Surveys and Land Tenure);
• the number of the original land title;
• the surface area actually measured, often different from the “announced” area;
• the boundary markers (B1 to Bn) and the distances between them;
• the easements: strips of land you cannot build on (right of way, road, utilities) — 4 m, 6 m, 8 m depending on the case;
• the surveyor’s name, licence number and the date;
• the cadastral stamp (stamp + date). Without that stamp the plan is worthless.

Announced area ≠ surveyed area

A seller may say “500 m²” in good faith, because that is what he was told. The survey
gives the real area. It may be smaller: part of it is taken by an
easement, or a neighbour has encroached. You pay for the surveyed area, not the announced
one.

To check before buying

• The survey plan is stamped by the cadastral service, with a recent date.
• The markers are there on the ground — go and see them, one by one, during the visit.
• The area on the plan matches what is being sold to you.
• The easements are shown, and you know what you will be able to build.
