Simeon v Potishoi & another (Civil Appeal E102 of 2021) [2026] KECA 936 (KLR)
The bottom line
#Kenya's Court of Appeal confirmed that a poorly witnessed will is invalid, a customary wife inherits, and courts without jurisdiction make void orders.
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 trial court erred in recognizing the 1st respondent as the widow of the deceased and therefore a beneficiary of the estate of the deceased alongside her children
- 2.Whether the trial court erred in its treatment of the will and declaring it invalid under section 11 of the Law of Succession Act
- 3.Whether the trial court erred in holding that the Principal Magistrate's Court at Kilgoris lacked pecuniary jurisdiction to deal with the cause
- 4.Whether the trial court erred in law and fact by failing to properly analyze the evidence and submissions of the parties
Key legal issues
#Proof of the 1st respondent's Maasai customary law marriage to the deceased
The trial court did not err in finding the 1st respondent to be a widow of the deceased; her customary marriage was proved to the required standard and the appellate court would not interfere.
Section 107 of the Evidence Act places the burden of proof on the party asserting the customary marriage, and the standard is balance of probabilities per Njoki v Mathara. The Supreme Court in Mary Nyambura Kangara cautions against lightly presuming marriage from cohabitation, requiring clear proof of customary rites or long cohabitation. However, once trial court findings on such evidence are persuasive and not wholly incredible, an appellate court should not interfere per Gituanja v Gituanja. The trial court weighed DW2's and relatives' testimony and found it persuasive, so the finding stands.
Validity of the deceased's will under section 11 of the Law of Succession Act
The will was invalid for want of attestation by two competent witnesses; the advocate's stamp affixed in the 'in the presence of' segment did not amount to attestation.
Section 11(c) mandates attestation by at least two competent witnesses, each signing in the presence of the testator. While advocates may in law act as witnesses, an advocate who merely drafts or certifies the will without expressly signing as a witness does not attest it. Here the advocate was the drafter and his stamp appeared under 'in the presence of' rather than the witness section. Attestation is a mandatory statutory formality, so the trial court correctly found the will invalid, and the submission that form was preferred over substance was misplaced.
Pecuniary jurisdiction of the Principal Magistrate's Court at Kilgoris
The magistrate's court lacked pecuniary jurisdiction since the value of the estate exceeded Kshs. 100,000; its orders were null and void ab initio, and the trial court was right to annul the grant.
The suit property measured 9.8 hectares (roughly 24 acres), obviously exceeding the Kshs. 100,000 statutory limit under section 48 of the Act. Citing Owners of Motor Vessel 'Lillian S', jurisdiction is everything and without it a court must down its tools; orders made without jurisdiction are null and void ab initio and cannot be cured by consent or acquiescence. The trial court was therefore right to annul the grant and order the cause to proceed afresh under its own jurisdiction.
Whether the trial court failed to properly analyze the evidence and submissions
The complaint was bereft of merit; the trial court considered the testimony, submissions and issues in detail and did a sterling job.
The Court noted that the trial court considered in detail the testimonies of both sides and the respective submissions, framed issues for determination, determined them and gave reasons, addressing the validity of the will, the question of beneficiaries and jurisdiction. The appellant's complaint that the trial court failed to properly analyze evidence and submissions was therefore without foundation.
Legal principles established
#- The burden of proving a customary marriage lies on the party asserting it, to the standard of balance of probabilities, and an appellate court should not interfere with a trial court's finding on the existence of a customary marriage unless the evidence is wholly incredible.
- A written will must be attested by two or more competent witnesses under section 11(c) of the Law of Succession Act; an advocate who merely drafts a will and whose stamp is affixed in the 'in the presence of' segment, without signing as a witness, is not an attesting witness.
- Where a subordinate court acts without jurisdiction, its orders are null and void ab initio, and proceedings conducted without jurisdiction cannot be cured by consent or acquiescence.
- On a first appeal, the primary duty of the appellate court is to re-evaluate, re-assess and re-analyze the entire evidence on record, both on points of law and fact, so as to reach its own independent conclusions.

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.
In conclusion, we are satisfied that the appeal is bereft of merit and is accordingly dismissed with costs to the respondents.
Taken together, these authorities determine that while courts must demand credible proof of customary marriage, once such evidence is found persuasive and not wholly incredible, an appellate court’s intervention is unwarranted.
although an advocate can in law be a competent witness, in this case the advocate was the drafter of the will and his stamp was afixed in the segment “in the presence of” rather than under the witness section. This did not satisfy the statutory requirement of attestation which is a mandatory requirement.
where a subordinate court acts without jurisdiction, its orders are null and void ab initio, as reiterated in Owners of Motor Vessel “Lillian S” v Caltex Oil (Kenya) Ltd [1989] KLR 1, in which it was held that jurisdiction is everything and without it a court must down its tools.
Our primary duty is to re-evaluate, re-assess, and re-analyze the entire evidence on record, both on points of law and fact so as to reach our own independent conclusions.
Issues in the judgment
#The judgment refers to the trial court variously as 'the trial court' and 'the first appellate court', creating ambiguity about the hierarchy of the decision under appeal; the High Court at Kisii is described as the trial court but is also styled 'first appellate court'.
The judgment states the court 'revert[s] to the reasoning of the Supreme Court' in Mary Nyambura Kangara, but the citation given is not verbatim-quoted, so the extent of adoption rests on paraphrase.
