Registered Survey vs Deed of Assignment

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.

That is true wherever the land is. If the property is in Lagos State or Ogun State, Smart Estate's paid TitleSecure check can add a written title check, but it is not a survey, it is not available in other states, and it does not guarantee title or replace your solicitor and surveyor.

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

The two documents complement each other; neither can stand in for the 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

1. Physical land inspected
2. Survey identifies parcel
3. Deed describes same parcel
4. Assignor's title chain supports interest
5. Required consent/stamping/registration
6. 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, your surveyor can check the plan against the records of the state's survey office, and your lawyer searches the Lagos State Land Registry; ask each to tell you in writing what they searched. Lagos also runs an online applicant portal, the Multipurpose Desk for land-related matters, through which some land applications, such as land regularisation, are made.

For Abuja, the official AGIS land-administration units include survey and Certified True Copy units, a deeds registry and legal searches.

For Ogun and every other state, use the survey office and land registry of the state where the land sits; each sets its own procedure and fees.

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

Filling in each row from the three sources shows exactly where a mismatch arose, which is where your surveyor and lawyer should start.

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 hypothetical wrong-plot scenario

Suppose a buyer, 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 is a paid title check ordered for one property. It is available only for property in Lagos State and Ogun State, and it is not offered on rentals. The type of property decides which check applies:

	TitleSecure Basic	TitleSecure Advanced
Price	₦20,000 per check	₦50,000 per check
For	Land	Property for sale other than land, such as a house or flat
Scope	A title check on the land	A full property check
Certified True Copy of the title document	Not included	Included
Written legal opinion	Not part of Basic	Included
Turnaround	24 hours	3 to 5 days

Both are title checks. Neither is a boundary survey, so neither tells you that the plot you walked on is the plot in the survey plan: only a surveyor on site can do that. Neither drafts or settles your deed of assignment either; that is your lawyer's job.

Neither check is instant. A listing on Smart Estate MLS shows the TitleSecure badge only after a check is complete and an administrator has applied it. The report is compiled from the records available at the time; it does not guarantee title and it does not replace your solicitor.

Property outside Lagos and Ogun: TitleSecure is not yet available there. Use the steps under "How buyers verify both": a registered surveyor to identify the parcel on the ground and check the survey with the state survey office, and your own solicitor to search the land registry of the state where the land sits and review the deed.

Smart Estate MLS verifies agents, not properties. You can find an identity-verified agent in the directory, and the page on how Smart Estate MLS checks agents and titles explains the difference. An agent's identity check says nothing about a survey or a deed.

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.
