Introduction

In Nigeria Land Law, ownership is not a passive guarantee but an active obligation. Section 16 of the Limitation Law of Lagos State, sets a strict countdown on how long a legal owner may sit on their rights while another person occupies their property. Where another person maintains open, uninterrupted possession without the owner’s permission for 12 consecutive years or between 20 and 30 years for a land held by or on behalf of the State, the law considers the owner’s right to sue extinguished. Adverse Possession reflects the utility rule that the law favors the productive user of the land over the sleeping owner who abandons an asset to decay.

Adverse possession in Nigeria is not a single, uniform national statute. It is anchored on a mosaic of state Limitation Laws, most of them modelled on the Limitation Act 1939 and the Limitation Act 1966 (applicable in the Federal Capital Territory). In Lagos State, the relevant provision is Section 16 of the Limitation Law, Cap. L67, Laws of Lagos State, 2015. Once the limitation period lapses, the true owner’s right to bring an action for recovery of land or trespass is statute-barred, and critically the title itself (not merely the remedy) is extinguished. This is what distinguishes adverse possession from an ordinary limitation defence; it operates to transfer beneficial ownership to the possessor, who may thereafter apply to be registered as owner in place of the original title-holder.

Elements of Adverse Possession

Nigerian courts apply the strict common law doctrine of nec vi, nec clam, nec precario (without force, without secrecy, without permission). An adverse possessor must prove three distinct elements:

• Nec Clam (without secrecy): The occupation must be open, visible and notorious. The occupant must treat the land as their own to the knowledge of the people in that locality.
• Nec Vi (Without Force): The initial entry and continued stay must not rely on intimidation that prevents the owner from asserting his legal rights.
• Nec Precario (Without Permission); The occupant must not have the consent of the owner. The moment an occupant signs a tenancy agreement, the possession becomes permissive not adverse.

In Onwugbufor v. Okoye (1996) 1 NWLR (Pt. 424) 252 at 282, Iguh JSC held that a party who relies on acts of possession and ownership must show that such acts were exercised nec vi, nec clam, nec precario over a sufficient length of time, such that any person asserting a contrary title would have known of the exercise of those rights and ought to have asserted his own title. The Supreme Court’s formulation remains the leading statement of the doctrine in Nigeria.

Does Possession Defeat Root of Title

A recurring trap for landowners and for occupants hoping to rely on long possession is treating “possession” as a self-standing claim. Where two parties both assert ownership and both lead evidence of possession, the law ascribes actual possession to the party with the better title, and treats the other as a trespasser. In Fasoro v. Beyioku (1988) 2 NWLR (Pt. 76) 263, the Supreme Court held that where there are conflicting claims to ownership and possession, effective and exclusive possession is sufficient to prove that an action in trespass cannot be ascribed to a party who fails to establish a better title. The case is frequently cited for the proposition that recent acts of possession, standing alone and without a pleaded and established root of title, cannot solely be a ground to claim title to land.

This sits alongside the five recognised methods of proving title to land laid down in Idundun v. Okumagba (1976) 9–10 SC 227 namely, by traditional evidence, by deeds or documents of title, by acts of ownership extending over a sufficient length of time, by acts of long possession and enjoyment, and by proof of possession of adjacent land. Long, unchallenged possession is only one of five roads to title in Nigerian law, and a claimant should plead whichever route the facts best support.

Adverse Possession Over Government or Family Land

Adverse Possession with regards to government land: Since the Land Use Act 1978 vested radical title to all land in each State in the Governor, who holds it in trust for the people, a person cannot ordinarily acquire title against the State itself by long possession, this is part of the policy reason the longer 20–30 year period applies where the land in dispute belongs to, or is held on behalf of, government. It is also why a statutory right of occupancy, once validly granted by the Governor over a parcel, operates to extinguish pre-existing rights in that parcel, long possession included. See Olagunju v. Adesoye (2009) 9 NWLR (Pt. 1146) 225, where the Supreme Court affirmed that the grant of a statutory right of occupancy automatically extinguishes all existing rights over the parcel of land in respect of which it is granted. This serves as a reminder that regularizing title through the Land Use Act can itself defeat a rival long-possession claim, and equally that an owner who allows a governor’s consent to lapse leaves the door open to an adverse claimant.

Adverse Possession with regards to Family Land: Where the land in dispute is family or communal land, possession by one branch of the family, or by a customary tenant, does not automatically become adverse to the rest of the family merely through the passage of time; Nigerian courts are historically slow to find that a customary tenancy has been forfeited, and a trespasser in possession can in any event maintain an action against everyone except the true owner. Nigerians abroad who inherited land through their families should treat any long-standing occupant; even a relative or an old family caretaker with the same documentary discipline recommended below, since kinship is not itself a defense to a properly pleaded adverse possession claim by the family.

Steps to prevent adverse possession

A frequent mistake by investors abroad and even resident landowners is assuming that erecting a boundary wall or painting “THIS LAND IS NOT FOR SALE / BEWARE OF 419” interrupts the limitation clock. Under Nigerian case law, physical assertions without legal action does not stop time from running. Painting a sign or shouting at an illegal occupant is not a legal interruption.

In Kazeem v. Mosaku (2007) 17 NWLR (Pt. 1064) 523 (SC), counsel relied on Isiba v. Hanson (1967) NSCC 3 for the converse but equally instructive point: mere length of possession, in that case 24 years, will not avail an occupant where he performed no overt act of ownership brought to the true owner’s knowledge. The following framework should be implemented by every landowner, developer, and investors abroad with real estate assets in Nigeria:

1. Instruct your lawyer to draft an agreement between you and anyone occupying your land for a certain period of time: Where you knowingly allow someone to occupy your land for a period, draft an agreement explicitly stating that occupation is permissive, temporary, and subject to revocation at the owner’s sole discretion upon written notice, with a token consideration (however nominal) paid during the period of occupancy. A signed acknowledgment of permission is one of the strongest defense to a future nec precario dispute.
2. Issue a formal notice to any trespasser: Serve a written notice on any trespasser or unauthorized squatter requiring them to desist, and put them on notice of impending legal repercussions. Keep proof of service (registered post, courier receipt, or a process server’s affidavit), this evidence is what later establishes that the owner had, or ought to have had, notice of any adverse assertion.
3. Conduct and record periodic site audit: Take geo-tagged photographs and carry out an updated perimeter/beacon inspection every 12–24 months. This also assists compliance with the surveyor’s-beacon obligations under the Land Use Act and gives contemporaneous, dated evidence to rebut any later claim of unbroken, unnoticed possession.
4. Regularize your possession: Where a right of occupancy or Certificate of Occupancy has not yet been perfected, pursue registration. A validly perfected title is far harder to defeat.

5. Institute an action and not just rely on reporting the matter to the police: Where an encroacher refuses to vacate after written notice, do not rely on police petitions alone. While police intervention can address criminal trespass or threats to the peace, it is necessary to institute an action in court for recovery of possession and, where the risk is urgent, to seek an interlocutory injunction restraining further acts of ownership pending trial.

CONCLUSION 

Adverse possession is not a doctrine that rewards land grabbers overnight; it rewards decades of an owner’s silence in the face of open, notorious, and unpermitted occupation. The Nigerian courts have consistently required an adverse possessor to prove, not merely assert, that possession was exercised nec vi, nec clam, nec precario over the full statutory period, and have been equally firm that neither a boundary wall nor a warning sign, without more, will vitiate the statute of limitation. The safest posture for landowners is proactive documentation and prompt legal action at the first sign of an unauthorized or overstaying occupant; for occupants, the doctrine is no shortcut, but a narrow and fact-intensive defense that fails the moment any permission, force, or concealment can be shown.
