The short answer: a survey plan is a drawing of your land. A registered survey plan is one the Lagos government has a copy of.
The difference is everything. An unregistered plan can be beautifully printed, signed and sealed — and still be worthless, because nothing ties it to the ground you were shown.
Three things make a survey registered: a licensed surveyor prepared it, it carries a unique plan number, and the has been lodged at the Surveyor-General's office.
Why this matters more than buyers realise
Your survey plan is what links the paper you are buying to the actual soil you stood on. Every other document — deed, gazette, C of O — describes land in words. Only the survey fixes its exact position on the earth.
Get this wrong and the rest collapses. Without a registered survey you cannot process Governor's Consent or a Certificate of Occupancy, you cannot obtain building approval, and no bank will lend against the property.
What a genuine survey plan shows
Pick up the document and look for these. A plan missing any of them deserves questions.
- The surveyor's name, signature, seal and number
- A unique plan number and the date of survey
- at each corner of the plot
- along every boundary
- GPS coordinates fixing the plot's position
- Scale, north arrow, and the local government area
- A stamp stating the land is free from government acquisition — or, where it is not, a number
Provisional versus registered
| Provisional plan | Registered plan | |
|---|---|---|
| Red copy lodged? | No | Yes |
| Government has a copy? | No | Yes |
| Details can still change? | Yes | No |
| Usable for C of O or consent? | No | Yes |
| Protects you in a dispute? | Weakly | Yes |
A provisional plan is not automatically fake. It is an early-stage document, and sellers sometimes present one honestly. But it is not proof of anything yet, and it should never be the survey you rely on at the point of payment.
Flying coordinates: the fraud to know about
Coordinates can be lifted from another property entirely.
Instead of measuring the land being sold, a dishonest surveyor copies coordinates from somewhere else. The plan looks perfect — seal, signature, beacon numbers, everything. But the coordinates point to a different plot, sometimes kilometres away.
Buyers have discovered this years later, after building, when their documents were finally submitted and the government mapped the coordinates to someone else's land.
A plan that looks authentic tells you nothing. Only checking the coordinates against government records does.
How to verify at the Surveyor-General's office
The Office of the Surveyor-General of Lagos State (OSGL) sits at Alausa, Ikeja. Four steps.
- Verify the surveyor first. Ask for the SURCON registration number and check it against the register at surcon.gov.ng. An unlicensed surveyor's plan carries no legal weight at the registry.
- Ask the seller for the Evidence of Lodgement. This is the receipt issued when the red copy was deposited — sometimes called a . Newer ones carry a scannable barcode.
- Confirm it independently at the Records Office at OSGL, Alausa, by requesting a Verification of Submission of Record Copy Plan. The seller's paperwork alone is not confirmation — a receipt can be forged as easily as a plan.
- Chart the land. plots your coordinates against government records. It catches flying coordinates, overlaps with other registered plots, drainage and pipeline setbacks, and acquisition status. The result is a .
Steps 3 and 4 answer different questions. Verification asks does this plan exist in government records? Charting asks is the land it describes safe? You need both answers.
What it costs
Survey fees in Lagos are regulated minimums set by SURCON and the Nigerian Institution of Surveyors, and vary by zone and plot size — Lekki and Victoria Island sit in the most expensive band, Ikorodu, Epe and Badagry in the cheapest.
| Item | Typical range |
|---|---|
| Survey of a residential plot | ₦425,000 – ₦1,600,000+ by zone and size |
| Red copy lodgement at OSGL | ₦200,000 – ₦350,000, charged separately |
| Charting / Land Information Certificate | ₦20,000 – ₦100,000 |
| Processing time after fieldwork | 10 – 21 working days |
Be wary of a quote far below these figures. The bulk of a survey fee is a mandatory payment to government, not the surveyor's profit — so a suspiciously cheap quote usually means the plan will never be lodged, or the surveyor is unlicensed. Fees are revised periodically; confirm current rates at Alausa.
Red flags
| What you see | What it means |
|---|---|
| No SURCON number on the plan | Not legally valid. Stop. |
| "The red copy is still processing" | The survey is not registered yet. It may never be. |
| Beacon numbers on paper don't match the pillars on site | The plan may not describe the land you were shown. |
| Seller insists you use their surveyor | Use your own. Always. |
| Quote far below the regulated minimum | Government fees are being skipped. |
| Only a photocopy is ever produced | Ask for the original and the lodgement receipt. |
Bottom line
A survey plan you cannot trace in government records is a drawing, not a document. Verify the surveyor's licence, confirm the red copy was actually lodged — independently, at Alausa — and chart the coordinates before you pay. Three checks, a few weeks, a fraction of the purchase price. They are the cheapest insurance in the whole transaction.
