The bottom line

What this practically means
#Executive summary
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Whether the plaintiff has established the requisite elements underpinning a claim for adverse possession or otherwise
- 2.What relief (if any) ought to issue
Key legal issues
#Whether the plaintiff established the ingredients of adverse possession
No. The plaintiff did not pay the last instalment of the purchase price and did not prove repudiation of the sale agreement, so time for adverse possession never commenced
Because the claim was founded on sale agreements, adverse possession could only begin on payment of the final instalment or repudiation of the contract. The plaintiff conceded in cross-examination that the balance of the purchase price, payable upon transfer, was never paid, and no transfer ever occurred. No evidence of repudiation was tendered. His occupation therefore rested on contract, not hostility, and the 12-year period never began to run.
Whether the sale agreement, executed before any grant of letters of administration issued, was valid
The agreement was illegal, null and void as it amounted to intermeddling with the estate of a deceased person contrary to Section 45 of the Law of Succession Act
The suit property was registered in the name of a deceased person who died in 1984, whose estate had not been succeeded. The vendor, Adriano Nthamburi Kahuria, held no grant of letters of administration when he sold the land in 2013, long before the grant issued in September 2025. He lacked capacity to dispose of the property, and the transaction amounted to intermeddling, an offence under Section 45 of the Law of Succession Act.
Whether a plaintiff who entered on the basis of an illegal contract should be evicted absent a counterclaim
Yes. A plaintiff cannot benefit from illegality; the court invoked its jurisdiction under Section 13(7) of the Environment and Land Court Act and its inherent jurisdiction to order eviction
Although the defendant filed no counterclaim, the court held that the absence of a counterclaim does not sanction illegality. Relying on the ex turpi causa maxim as quoted in Mapis Investment v Kenya Railways, and on the inherent jurisdiction explained in Narok County Government v Ntutu, the court found jurisdiction under Section 13(7) of the Environment and Land Court Act to order the plaintiff to vacate within 90 days.
Legal principles established
#- Where a claim for adverse possession is predicated on a sale agreement, time only begins to run upon payment of the last instalment of the purchase price or upon repudiation of the contract
- A purchaser who has not completed payment of the purchase price remains in occupation on the basis of contract and cannot invoke adverse possession
- A party cannot benefit from an illegality; no court ought to enforce an illegal contract
Court orders
#- 1.The Plaintiff's suit be and is hereby dismissed
- 2.Costs of the suit be and are hereby awarded to the Defendant, to be agreed upon and in default taxed in the conventional manner
- 3.The Plaintiff be and is hereby ordered to vacate and hand over vacant possession of the suit property to the defendant within 90 days from the date hereof
- 4.In the event of default, the defendant shall be at liberty to evict the plaintiff either by himself, agents or servants, and an eviction order shall issue
The bench
#One judgment of the whole court — no separate or dissenting opinions.
Wrote the judgment
- Jurisdiction invoked
- Order 37 Rule 7 of the Civil Procedure Rules, 2010; Sections 1A, 1B and 3A of the Civil Procedure Act; Section 38 of the Limitation of Actions Act; Section 13(7) of the Environment and Land Court Act, 2011
Relief refused
#Declaration that the plaintiff has become entitled by adverse possession to 1 acre of Abothuguchi/Gaitu/1143
Plaintiff failed to prove payment of the full purchase price or repudiation of the sale agreement, so occupation never became adverse
Order that the plaintiff be registered as proprietor of 1 acre of the suit property and that the defendant execute transfer instruments
The sale agreement was vitiated by illegality as the vendor had no grant of letters of administration and no capacity to sell
Costs
Costs of the suit awarded to the Defendant, to be agreed upon and in default taxed in the conventional manner
Quotable passages
#Verbatim from the judgment, each located to the page it appears on in the official PDF — so these can be cited and checked directly.
The Plaintifi’s suit be and is hereby dismissed.
Additionally, and taking into account the provisions of Section 13 [7] of the Environment and Land Act,2011 ; the Plaintifi be and is hereby ordered to vacate and hand over vacant possession of the suit property to the defendant within 90 days from the date hereof.
Where the purchaser, who is in occupation on the basis of the sale/purchase agreement, has not concluded the payment of the purchase price, such a purchaser cannot invoke the doctrine of adverse possession.
In this regard it remains outstanding to date. Consequently, the impugned occupation did not become adverse or hostile. Time for computing the adverse claim, therefore, did not commence to run in favour of the plaintifi in accordance with the law.
It matters not whether the defendant has pleaded the illegality or whether he has not. If the evidence adduced by the plaintifi proves the illegality the court ought not to assist him.
A person who claims adverse possession must inter alia show: (a) on what date he came into possession. (b) what was the nature of his possession? (c) whether the fact of his possession was known to the other party. (d) for how long his possession has continued and (e) that the possession was open and undisturbed for the requisite 12 years.
Issues in the judgment
#Inconsistent dates for the sale agreements: the originating summons pleads agreements dated 21.6.2013, 17.7.2013 and 9.9.1013, while the judgment later refers to agreements dated 21.6.2013; 17.7.2013; and 9.9.2023
Confusion in the identity of the vendor: the pleading names Adriano Nthamburi, while evidence and analysis name Jeremiah Kahuria Randu and Adriano Nthamburi Kahuria
The supporting affidavit is attributed to 'Joseph Mwendan M'Mukiri' while the plaintiff is named 'Joseph Mwenda M'Mukiri'
