Can a wife stop the auction of family property simply because she never consented to its mortgage, even when another wife has already signed the bank’s consent form? The Court of Appeal has weighed in, and the answer has important implications for polygamous families, lenders and property transactions in Kenya.
Imagine discovering that the family home is about to be auctioned over a loan you knew nothing about. You rush to court, not only to stop the sale but also to argue that the bank had no right to accept a mortgage without your consent. There is just one complication: your husband has another wife, and she was the one who signed the bank’s spousal consent form. This was the unusual dispute before the Court of Appeal in Elyjoy Kageni v Bank of Africa (K) Ltd & 3 others [2026] KECA 1921 (KLR). At its heart was a question that Kenyan property law has not adequately addressed: in a polygamous marriage, must a bank obtain the consent of every wife before accepting matrimonial property as security?
The dispute arose when Bank of Africa advanced KShs 20.6 million to United Brothers Camps Ltd in 2012. The loan was secured by a charge over L.R. No. Chuka Township/39, registered in the name of Humphrey Mbabu Mbaka, a director of the borrowing company. Humphrey and his co-director, Lucyline Kanyua Mutindwa, presented themselves to the bank as husband and wife living on the property. Lucyline signed the spousal consent. When the borrower defaulted and the bank initiated recovery proceedings, Elyjoy Kageni emerged, claiming to be Humphrey’s first wife under Meru customary law. She challenged the proposed auction, arguing that she had never consented to the charge and that the bank had therefore failed to comply with section 79(3) of the Land Act, 2012.
The Environment and Land Court initially dismissed her claim, questioning whether she had established a valid marriage. However, the Court of Appeal took a different view. It recognized Elyjoy as Humphrey’s wife, relying on evidence of the customary union, including testimony from Humphrey’s father acknowledging both women as his son’s wives. The Court of Appeal turned to section 79(3) of the Land Act, which requires a charge over a matrimonial home to be executed by the chargor and any spouse of the chargor living in that matrimonial home.
The Court admitted that this was “not an easy question” because the law does not expressly address polygamous marriages. Nevertheless, it focused on the requirement that the spouse must be living in the matrimonial home. Elyjoy had never lived on the property. It was occupied by Humphrey, Lucyline and Elyjoy’s son. She also had no knowledge of the loan or the bank’s involvement until she learnt of the intended auction. The bank, for its part, had not been informed of her existence.
In the Court’s view, it would be unreasonable and unjust to expect the bank to discover a wife whose existence had been concealed from it and who did not reside on the property. Since Lucyline lived there and had consented to the charge, the bank had satisfied the requirement under section 79(3). The appeal was consequently dismissed with costs. The important distinction, being someone’s wife does not automatically mean your consent is required for every transaction involving property owned by that spouse. Under the Court’s interpretation, occupation of the matrimonial home was central to determining whose consent the lender needed.
For banks and lenders, the judgment is not a license to accept one signature and proceed without further enquiries. Due diligence remains essential. Lenders should establish who occupies the property, make enquiries about the chargor’s marital status and obtain consent from every spouse living in the matrimonial home. Where a lender knows of another resident spouse, ignoring that information could expose the transaction to challenge. Borrowers and chargors must also disclose their marital circumstances honestly. Concealing another marriage may create disputes that threaten the security transaction and complicate subsequent enforcement.
For spouses in polygamous marriages, particularly those who do not live on property in which they claim an interest, the decision highlights the importance of taking proactive steps. Section 12(2) of the Matrimonial Property Act provides for the protection of a spouse’s interest through registration of a caution or other appropriate protective measure. A registered caution can alert prospective lenders and purchasers to an existing claim that might otherwise remain undisclosed. Importantly, losing a challenge against a bank does not necessarily extinguish a spouse’s beneficial interest against the other spouse. A claim for a declaration of that interest may still be pursued under section 17 of the Matrimonial Property Act.
Shares acquired during marriage may constitute matrimonial property where a spouse establishes a beneficial interest through their contribution, even where the shares are registered in the other spouse’s name, as recognised in SNK v MSK & 5 others [2015] KECA 1010 (KLR). However, this does not automatically entitle a spouse to the company’s underlying assets, since under Salomon v Salomon & Co Ltd [1897] AC 22, a company has a separate legal personality from its shareholders. Accordingly, a spouse may claim an interest in the shares but not directly in the company’s property, unless circumstances justify looking beyond the company’s separate legal personality.
Ultimately, Kageni exposes a gap between Kenya’s recognition of polygamous marriages and a statutory framework that largely assumes a two-spouse arrangement. Although the Court provides guidance on the importance of occupation and a lender’s knowledge, difficult questions remain, particularly where multiple wives occupy the same matrimonial home or a lender knowingly obtains consent from only one. The decision therefore leaves room for further judicial interpretation and legislative reform. The key takeaway is that being a recognized spouse does not automatically confer a right to veto a mortgage. Equally, for lenders, proper due diligence is essential, while spouses must be proactive in protecting their matrimonial interests before a property is placed at risk.
