A survey plan and a deed of assignment perform different jobs in a Nigerian land transaction. A survey plan identifies and describes land spatially. A deed of assignment records the terms by which one party assigns an interest in land to another.
Neither document should be treated as a complete title on its own. Buyers need an appropriate survey professional to match the physical property to the survey evidence and an independent lawyer to investigate the parties, title chain, deed, consent, registration and current official records.

The simplest distinction
| Question | Survey plan | Deed of assignment |
|---|---|---|
| What does it primarily describe? | The land’s spatial identity | The legal transaction and assigned interest |
| Typical focus | Location, dimensions, coordinates, boundaries, area | Parties, property, interest, price/consideration, obligations |
| Main professional | Appropriate survey professional | Property lawyer |
| Does it alone prove ownership? | No | No |
| Must it match the physical land? | Yes | Yes, through its property description |
| May official processing matter? | Yes, depending on jurisdiction and purpose | Yes, including consent, stamping or registration where applicable |
This information-bearing visual makes the key point: the documents complement rather than replace each other.
What a survey plan does
A survey plan may show:
- location;
- coordinates;
- measurements;
- area;
- boundary lines;
- beacon references;
- plot or block;
- adjoining parcels or features;
- road or access context;
- surveyor information;
- preparation date and other technical details.
It helps answer: Which land are we talking about?
At inspection, the survey professional can help relate the plan to the terrain and visible markers. The plan can then be compared with title documents, registry information and government acquisition or planning data.
A marketing layout, estate brochure or hand-drawn sketch is not automatically a survey plan.
What “registered survey” may mean
The phrase is used loosely in adverts. Ask the speaker to explain:
- which survey is meant;
- who prepared it;
- what professional status applies;
- which office, authority or process received or recorded it;
- what lodgement, registration, charting or approval occurred;
- what official reference supports the claim;
- whether it relates to the exact plot.
Do not infer that “registered survey” means:
- title is registered;
- seller owns the land;
- government has granted a C of O;
- land is free from acquisition;
- planning approval exists;
- every boundary dispute is resolved.
The relevant Nigerian survey and land-administration process varies by jurisdiction.
What a deed of assignment does
A deed of assignment typically records an assignment of a stated interest from an assignor to an assignee, subject to the exact drafting and law.
It may identify:
- parties and capacities;
- background or recitals;
- property description;
- interest assigned;
- consideration;
- rights and obligations;
- representations or covenants;
- execution;
- schedules and attached survey;
- consent, stamping or registration steps.
It helps answer: What interest did these parties agree to transfer, on what terms?
The deed should be prepared or reviewed by an independent Nigerian property lawyer. Do not use a generic online form without title and transaction analysis.
How the documents should connect
- Physical land inspected
- Survey identifies parcel
- Deed describes same parcel
- Assignor's title chain supports interest
- Required consent/stamping/registration
- Current registry and seller authority
Check that:
- plot, block and scheme agree;
- measurements and area agree or are lawfully reconciled;
- survey references in the deed are correct;
- the deed’s schedule describes the inspected land;
- the assignor’s prior title concerns the same parcel;
- official records and subsequent transactions align.
A small numerical difference can indicate a drafting error, resurvey or serious property mismatch. Do not guess which.
What a survey cannot prove
A survey plan alone does not establish:
- that the named client owns the land;
- the legal root of title;
- an assignment between parties;
- authority of the seller;
- absence of mortgages or prior sales;
- consent to a transaction;
- planning approval;
- building condition;
- safe payment beneficiary.
A person can commission survey work over land they do not own. The plan may accurately describe a parcel while the ownership claim remains defective.
What a deed cannot prove
A deed alone does not establish:
- that the assignor had the interest claimed;
- that the physical land matches the description;
- that signatures and authority are genuine;
- that required consent, stamping or registration occurred;
- absence of a prior assignment or mortgage;
- government acquisition or planning status;
- current possession;
- document authenticity.
Two parties can sign an agreement concerning land the assignor cannot lawfully transfer.
That is why title verification must extend beyond the deed.
How buyers verify both
Preserve complete copies
Obtain the survey plan, deed schedules, prior title instruments and supporting records. Do not accept cropped pages.
Inspect the exact land
Use an appropriate survey professional to relate the supplied survey to the actual site, access and boundaries.
Check professional and official references
Confirm survey details through the appropriate official or professional route. Your lawyer should determine the relevant land-registry, survey-office or other search.
For Lagos, the official Lagos State Land Administration Portal describes land regularisation and Land Information Certificate services.
For Abuja, the official AGIS land-administration units include survey, title, CTC, deeds registry and legal-search functions.
Trace the title chain
The lawyer should connect the assignor to the interest through prior deeds, allocation, C of O, consent, probate, court or other relevant evidence.
Read C of O verification and Governor’s Consent explained.
Search current interests
Investigate registered transfers, mortgages, restrictions, revocation, acquisition, disputes and possession as appropriate.
Review the new deed
The buyer’s deed must accurately reflect the verified parties, property, interest, conditions and completion plan.
Document comparison checklist
| Field | Survey plan | Deed/title documents | Physical/official check |
|---|---|---|---|
| Location | Coordinates and locality | Property description | Site and registry |
| Plot/block | Technical identifier | Schedule/recital | Layout and official record |
| Area | Survey measurement | Stated land area | Resurvey/reconciliation |
| Boundaries | Lines/beacons | Referenced survey | Ground identification |
| Owner/client name | May name commissioning client | Assignor/holder | Title chain and authority |
| Date | Survey preparation | Execution/transaction | Chronology |
| Reference | Survey number | Title/registry details | Issuing or recording source |
This information-bearing visual helps professionals identify where a mismatch arose.
Common mismatches
Different land area
Do not simply choose the larger figure. The surveyor and lawyer should identify whether the cause is resurvey, excision, road setback, drafting or wrong land.
Different plot or block
This can indicate the wrong estate phase or parcel. Stop until reconciled.
Deed has no survey attachment
The property may still be described by other identifiers, but counsel and the surveyor must decide whether it is sufficiently and correctly identified.
Survey client is not the seller
The client name on a survey does not necessarily prove ownership. Investigate why it differs and trace title.
New survey replaces old survey
Establish why, which land each describes, whether official records were updated and whether the new plan changes the transaction.
Deed and inspection differ
Do not sign. Correct the property description after professional verification.
A practical wrong-plot scenario
Emeka inspects Plot 18 in a Lagos estate and receives a survey that appears to show the same corner position. The proposed deed, however, describes Plot 81 in another block. The marketer says the numbers are interchangeable because the estate changed its layout.
That explanation may be possible, but it is not enough. Emeka’s survey professional should identify the land inspected, compare the old and revised layouts and establish which survey now corresponds to the physical plot. His lawyer should examine the estate’s authority for the change, the seller’s title to the correct plot, allocation records and the deed schedule. Relevant official records should also be reconciled.
Until the evidence agrees, Emeka does not sign or pay. Changing “81” to “18” by hand would not prove that the seller can transfer Plot 18.
The broader guide to finding genuine land for sale in Lagos connects this document check to acquisition, planning, access and allocation risks.
Who should do what
| Participant | Appropriate role |
|---|---|
| Buyer | Define property, preserve records, appoint independent advisers |
| Survey professional | Identify parcel and interpret survey evidence within scope |
| Property lawyer | Investigate title, parties, deed, consent, registration and agreement |
| Registry/authority | Provide official records or services within jurisdiction |
| Agent/platform | Support discovery, listing context and controlled enquiry |
The listing professional should not be the sole source of survey and title conclusions.
How Smart Estate TitleSecure fits
Smart Estate TitleSecure can organise a scoped review of supplied land and title evidence.
Basic screening may identify a missing plan, inconsistent reference or apparent mismatch requiring escalation. It is not a boundary survey, government search or legal opinion.
A Full engagement may coordinate relevant professionals and official checks within its written scope. It should state findings and unresolved differences. It does not guarantee ownership.
Smart Estate MLS supports approved active property discovery. IDX, professional website development and AgentForge strengthen permissioned distribution, digital presence and professional practice. None substitutes a deed or survey.
Use how to verify land title in Nigeria for the complete chain.
Keep the survey and deed comparison tied to the same inspected parcel. If coordinates, measurements, parties or property descriptions do not reconcile, neither document should be used to explain away the other.
Frequently asked questions
Which is more important: survey or deed?
They answer different questions. A land transaction commonly requires both spatial identity and legal transfer evidence, plus other checks.
Does a registered survey make land genuine?
No. It may support parcel identification within its scope. Ownership, acquisition, title chain and transaction authority remain separate.
Can I buy with only a deed?
Do not proceed without sufficient property identity and title investigation. Your advisers should determine the required evidence.
Can the survey be in someone else’s name?
The survey’s named client does not automatically determine ownership. The difference must be explained and the title chain independently verified.
Is a deed valid without Governor’s Consent?
The legal consequences depend on the interest, transaction, applicable law and perfection status. Obtain counsel’s advice rather than relying on a generic answer.
Does Smart Estate prepare either document?
Do not infer drafting or survey services beyond an accepted written engagement. Smart Estate can support defined title-review coordination through TitleSecure.
What if I am buying from abroad?
Use the diaspora title-verification checklist, appoint independent professionals and require direct reports.
