The Legal Checklist: 7 Documents You Must Verify Before Buying Property in Nigeria

Introduction: The High Stakes of Property Investment

Property investment represents one of the most significant financial decisions most Nigerians will make. With land values in prime areas of Lagos appreciating by up to 30% annually and similar trends in other urban centers across the country, real estate continues to be an attractive investment vehicle. However, behind these promising returns lies a landscape fraught with potential legal complications that have left many investors with costly regrets.

Recent Lagos State Land Bureau data indicates that approximately 25% of property disputes arise from inadequate documentation verification. The Nigerian Institution of Estate Surveyors and Valuers reports that an estimated ₦5 billion is lost annually to property fraud nationwide. These sobering statistics underscore a critical reality: thorough legal verification is not merely procedural bureaucracy but the foundation of secure property investment in Nigeria.

This comprehensive guide examines the seven essential documents you must meticulously verify before finalizing any property purchase in Nigeria, providing you with the knowledge to safeguard what may be your most significant investment.

1. Certificate of Occupancy (C of O): The Ultimate Proof of Ownership

What It Is

The Certificate of Occupancy is the supreme document in the Nigerian property ownership hierarchy. Issued under the Land Use Act of 1978, this document represents the government’s official recognition of a person’s right to occupy a specific piece of land. It effectively serves as the constitutional foundation of property ownership in Nigeria.

Why It Matters

Unlike property systems in some other countries, all land in Nigeria is technically held in trust by the government, with occupants granted rights of usage. The C of O represents the government’s formal acknowledgment of these rights, making it the most authoritative evidence of legitimate ownership.

Verification Process

To verify the authenticity of a Certificate of Occupancy:

  1. Request the original C of O from the seller and examine it for the state government’s watermark, official seals, and signatures.
  2. Search the relevant state’s Land Registry to confirm the document is registered correctly and matches their records.
  3. Verify that the named owner on the C of O corresponds with the seller or that there is a proper chain of ownership documents if the seller acquired the property from the original owner.
  4. Check the land use designation (residential, commercial, agricultural) to ensure your intended use aligns with permitted usage.

Red Flags to Watch For

“We recently represented a client who purchased a property in Victoria Island, Lagos with what appeared to be a genuine C of O,” recounts Barrister Folake Adeyemi, a Lagos-based property lawyer. “Upon closer inspection at the Land Registry, we discovered the document was skillfully forged. The original land was government-acquired property. Had we not verified, our client nearly lost ₦450 million to fraudsters.”

Be particularly wary if the seller only provides photocopies, claims the original is “being processed,” or if the document lacks proper seals or appears altered.

2. Survey Plan: Defining Your Property’s Boundaries

What It Is

A survey plan is a technical document prepared by a registered surveyor that delineates a property’s exact boundaries, dimensions, and geographical coordinates. It serves as the spatial definition of what you are purchasing.

Why It Matters

Property disputes in Nigeria frequently stem from boundary disagreements. The survey plan provides indisputable evidence of the land you are entitled to occupy. Without it, you risk purchasing a property with uncertain boundaries, potentially leading to encroachment issues and costly litigation.

Verification Process

For proper verification:

  1. Ensure the survey plan is prepared by a registered surveyor with their official stamp and registration number.
  2. Verify that the survey plan has been lodged with the Office of the Surveyor-General in the relevant state.
  3. Conduct a site visit with a surveyor to confirm that the physical boundaries match those in the survey plan.
  4. Cross-reference the coordinates and measurements with those in the Certificate of Occupancy to ensure consistency.

Real-Life Consequences

Mr. Adebayo Ogunlesi, a real estate investor from Abuja, shares his experience: “I purchased land in a developing area of Abuja without properly verifying the survey plan. Two years later, when I started construction, I discovered that nearly 30% of what I thought I owned had been sold to another person. The original survey plan had been altered to show a larger piece of land than what was being sold.”

3. Deed of Assignment: The Transfer of Ownership Rights

What It Is

The Deed of Assignment is a legal document that transfers ownership rights from the seller to the buyer. It details the terms and conditions of the property transfer, including the sale price and the specific rights being conveyed.

Why It Matters

This document establishes the legal basis for your claim to the property. Without a properly executed Deed of Assignment, your ownership claim remains legally vulnerable, regardless of financial transactions.

Verification Process

For thorough verification:

  1. Ensure a qualified legal practitioner prepares the Deed.
  2. Confirm that all parties named in the document have signed in the presence of witnesses.
  3. Verify that the property description in the Deed matches the Certificate of Occupancy and Survey Plan.
  4. Check that the Deed includes a declaration that the transferor has not previously assigned their interest to another party.
  5. Ensure the Deed is dated and properly stamped by the state’s Stamp Duty Office.

Strategic Considerations

“The Deed of Assignment must be carefully scrutinized for encumbrances,” advises Chief Anthony Idigbe, SAN, a property law expert. “I’ve seen cases where a seller failed to disclose existing financial claims against the property, resulting in the new owner inheriting significant debt obligations. Your legal representative should insert appropriate protective clauses to shield you from undisclosed liabilities.”

4. Tax Clearance Certificate: Confirming Financial Compliance

What It Is

A Tax Clearance Certificate (TCC) confirms that the property seller has fulfilled their tax obligations to the government, clearing the way for property transfer.

Why It Matters

Under Nigerian law, property transfers can be invalidated if the seller has outstanding tax liabilities. Additionally, property registration processes typically require evidence of tax compliance from both parties.

Verification Process

To verify tax compliance:

  1. Request the seller’s Tax Clearance Certificate for at least the past three years.
  2. Confirm the certificate’s authenticity with the relevant tax authority (Federal Inland Revenue Service or State Internal Revenue Service).
  3. Verify that the certificate covers the appropriate assessment period and reflects accurate income declarations.

Financial Implications

“Tax verification is frequently overlooked, but it carries significant financial implications,” notes Mrs. Zainab Ibrahim, a tax consultant in Kano. “I witnessed a case where a buyer discovered, post-purchase, that the property had ₦3.5 million in unpaid taxes accumulated over five years. The local government placed a lien on the property, preventing the new owner from developing it until the debt was settled.”

5. Building Approval/Permit: Ensuring Structural Legitimacy

What It Is

Building approval, also known as a building permit or planning permission, is official authorization from the relevant urban planning authority that confirms a structure complies with building codes, zoning regulations, and environmental standards.

Why It Matters

Structures without proper building approval are technically illegal constructions. Government authorities can demolish unauthorized structures or impose substantial fines, regardless of how much you paid for the property.

Verification Process

For complete verification:

  1. Request the original building approval documents from the seller.
  2. Visit the local planning authority to confirm the approval’s authenticity and ensure it hasn’t been revoked.
  3. Verify that the approved building plans match the actual structure on the property.
  4. Check for any enforcement notices or stop-work orders against the property.

Consequences of Non-Compliance

The consequences of overlooking building approval verification can be devastating. In 2021, over 700 buildings were marked for demolition in Abuja alone due to violations of approved plans or lack of proper permits.

Architect Oluwaseun Davies recounts: “A client purchased a three-story building in Port Harcourt, only to receive a demolition notice two months later. The investigation revealed that while the seller had obtained approval for a two-story structure, they had illegally added a third floor. The new owner faced the choice of removing the top floor or paying significant penalties—neither of which had been factored into their investment calculations.”

6. Receipt of Purchase and Evidence of Payment: Documenting Financial Transactions

What It Is

Receipts and payment evidence constitute documentation of all financial transactions related to the property purchase, creating a verifiable trail of consideration exchanged.

Why It Matters

In Nigerian property law, evidence of payment is crucial proof that consideration was exchanged, strengthening your ownership claim if challenged. Proving that you paid for the property can become problematic in disputes without proper documentation.

Verification Process

To establish a solid financial record:

  1. Ensure all payments are documented through official channels, preferably bank transfers or checks rather than cash transactions.
  2. Obtain official receipts for each payment, signed by the seller.
  3. Document all transactions in the sale agreement, specifying amounts, payment dates, and methods.
  4. Retain evidence of the fund source to demonstrate legitimacy if questioned during registration processes.

Practical Protection

“Payment documentation saved my client’s investment,” shares Barrister Emeka Okafor from Enugu. “When a seller’s family members contested a land sale after his passing, claiming the transaction never occurred, our meticulously documented payment evidence—including bank transfers, signed receipts, and witnessed payment acknowledgments—proved decisive in court, preserving my client’s ownership rights.”

7. Letter of Allocation (for Government Schemes): Verifying Government Authorization

What It Is

A Letter of Allocation is an official document issued by the relevant government agency assigning specific property to an individual or organization for properties within government housing or land schemes.

Why It Matters

Government-allocated properties follow distinct legal frameworks. Without proper allocation documentation, properties in government schemes may be reclaimed, regardless of subsequent private transactions.

Verification Process

For government allocations:

  1. Verify the authenticity of the allocation letter with the issuing government agency.
  2. All required fees and development levies associated with the allocation have been paid.
  3. Check that the allocation hasn’t been revoked or reassigned.
  4. Verify that the seller has complied with any development timelines or conditions specified in the allocation.

Cautionary Tale

“Government allocations carry unique risks,” warns Mrs. Halima Suleiman, who learned this lesson firsthand in Lagos. “I purchased a property with what appeared to be valid allocation papers, only to discover the original allocation had been revoked three years earlier due to the original owner’s failure to develop within the stipulated timeframe. The land was legally no longer theirs to sell despite my purchase, resulting in financial loss and prolonged litigation.”
