Monicah Njeri Mwangi v Peter Karanja Mwangi
The bottom line
#The Court of Appeal confirmed that a woman married under Kikuyu woman-to-woman custom only inherits from her own spouse's estate, not a co-wife's.
What this practically means
#Executive summary
#Key legal issues
#Whether the appellant, claiming to be a wife of Njeri's co-wife Kanuthu under a woman-to-woman marriage, could inherit from Njeri's estate
The Court found that even if the appellant was a 'wife' of Kanuthu, her inheritance right lay in Kanuthu's estate, not Njeri's; she failed to prove her claim to the required standard and belongs to Kanuthu's family tree.
The Court accepted that woman-to-woman marriage is recognised under Kikuyu customary law, protected by Article 11(1) of the Constitution and section 3(5) of the Law of Succession Act. However, that recognition did not assist the appellant: on the evidence she was married to Kanuthu, Kanuthu left her own property, and any claim she had should be pursued there. Her evidence was contradictory, insufficient and unclear, and she failed to discharge the burden of proving her entitlement to Njeri's estate.
Who are the beneficiaries of Njeri's estate
The beneficiaries are the children sired by Njeri's wives, Lydia and Mary; even if the respondent is a grandson rather than a son, he is more entitled than the appellant, who belongs to Kanuthu's lineage.
The undisputed facts were that Njeri married two women, Lydia and Mary, in woman-to-woman marriages to preserve the family line, and those women sired children regarded as the family's children. The appellant did not dispute the other children of Lydia and Mary. By contrast, the appellant's connection ran through Kanuthu, a separate co-wife with her own estate, disqualifying her from a share of Njeri's property.
Whether claims by alleged purchasers of portions of the estate should have been considered
The alleged buyers filed only affidavits, gave no evidence and were not cross-examined, so the trial Judge was right not to consider their claims.
Where a matter proceeds by viva voce evidence, a party asserting a purchase of estate property must support the claim with testimony subject to cross-examination. The alleged buyers, including John Kamande named in the memorandum of appeal, did not do so, and it was unclear whether John Kamande was the same as beneficiary Joseph Kamande. The trial Judge therefore could not be faulted for disregarding their claims.
Legal principles established
#- On a first appeal, the Court of Appeal must reconsider and evaluate the evidence afresh and draw its own conclusions, while making due allowance for not having seen or heard the witnesses.
- Woman-to-woman marriages recognised under Kikuyu customary law are recognised under the Constitution and the Law of Succession Act, and courts may receive evidence of African customary law by oral evidence or recognised treatise under Rule 64 of the Probate and Administration Rules.
