Adverse Possession in Kenya: Key Takeaways from the Court of Appeal's Decision in Mwalimu & 6 Others v Halal & Another [2025] KECA 1186 (KLR)

Introduction

The doctrine of adverse possession remains one of the most significant principles in Kenya's land law. It allows a person who has occupied another person's land openly, continuously, and without permission for a period of at least twelve years to apply for ownership of that land.

The recent Court of Appeal decision in Mwalimu & 6 Others v Halal & Another [2025] KECA 1186 (KLR) has provided important clarification on the requirements for a successful claim of adverse possession and serves as a reminder that mere occupation of land for a long period is not enough.

The Case

The dispute concerned Plot No. Mombasa Island Block XV/31, which had been occupied by the family of the late Fadhili Mwalimu for several decades. The family operated a motor vehicle garage on the property and argued that they had occupied the land continuously for over thirty years without paying rent. On this basis, they sought to be declared owners of the property through adverse possession.

The Court of Appeal dismissed the claim, finding that the family's occupation originated from a tenancy arrangement entered into by their late father with the previous owner of the property. As a result, the occupation was initially permissive and could not automatically become adverse simply because many years had passed.

Key Principles Confirmed by the Court

1. Long Occupation Alone Is Not Enough

One of the most important findings of the Court was that occupation of land for more than twelve years does not automatically entitle a person to ownership through adverse possession.

A claimant must demonstrate that their occupation was:

• Open and visible;
• Continuous and uninterrupted;
• Exclusive; and
• Hostile to the rights of the registered owner.

The court emphasized that the quality of possession is just as important as the length of time spent on the land.

2. A Tenant Cannot Easily Claim Adverse Possession

The Court reaffirmed that occupation arising from a tenancy, lease, or licence is permissive. A person who occupies land with the owner's consent cannot claim adverse possession unless they clearly demonstrate that they no longer recognize the owner's title and begin occupying the property in a manner inconsistent with the owner's rights.

In this case, even if the relationship between the parties became hostile following a rent demand in 2002, the suit was filed in 2010, only eight years later. This fell short of the statutory twelve-year requirement.

3. Fraud and Adverse Possession Are Different Claims

The appellants also argued that the respondents had acquired title fraudulently. However, the Court held that a party cannot simultaneously challenge the validity of a title and claim adverse possession against the same title.

An adverse possession claim assumes that the registered title is valid but has become vulnerable due to prolonged adverse occupation. A fraud claim, on the other hand, seeks to invalidate the title altogether. The two claims cannot comfortably coexist.

Practical Lessons for Landowners and Investors

The decision provides valuable lessons for landowners, buyers, developers, and investors.

Take Possession Promptly

Purchasers who acquire land should take physical possession as soon as possible after completion. Merely obtaining a title deed may not be sufficient protection if the property remains occupied by third parties for many years.

Buyers should ensure that they:

• Obtain vacant possession;
• Conduct regular inspections;
• Secure the property where necessary; and
• Maintain records of possession and occupation.

Monitor Expired Leases and Tenancies

Landowners should be particularly cautious where tenants remain on the property after the expiry of a lease or where occupants continue using the land without paying rent.

Failure to take action against unauthorized occupation may eventually expose the owner to adverse possession claims if the occupation continues uninterrupted for the statutory period.

Formalize Occupation Arrangements

Many disputes arise from informal arrangements involving relatives, friends, caretakers, or long-term occupants. Landowners should document such arrangements through written agreements to avoid uncertainty regarding the nature of the occupation.

Proper documentation can be critical in demonstrating that the occupation remained permissive and never became adverse.

Conclusion

The Court of Appeal's decision in Mwalimu & 6 Others v Halal & Another reinforces the principle that adverse possession involves more than simply occupying land for a long period. The claimant must prove that the occupation was open, continuous, exclusive, and adverse to the interests of the registered owner for at least twelve years.

For landowners, the judgment highlights the importance of actively managing property, documenting occupation arrangements, and taking prompt action where unauthorized occupation occurs. For occupiers seeking to rely on adverse possession, the case serves as a reminder that the legal threshold remains high and each claim will be determined on its specific facts.

As land ownership disputes continue to arise across Kenya, this decision provides useful guidance on the circumstances under which courts will recognize—or reject—claims based on adverse possession.
