Spousal Consent in Polygamous Marriages in Kenya: Which Wife Must Consent to a Charge over Matrimonial Property?

Kenyan law requires a spouse’s consent before selling, leasing, or charging matrimonial property. But the statutes were drafted with one spouse in mind. What happens when a man has two or more wives and only one signs the bank’s spousal consent form? On 25 September 2026, the Court of Appeal at Nyeri answered that question in Kageni v Bank of Africa (K) Ltd & 3 others (Civil Appeal No. 186 of 2018). A first wife, married under Meru customary law, asked the court to nullify a Kshs 20.6 million charge over the family property because she had never consented. She proved she was a wife, but she still lost.

This guide explains the facts, the issues the court decided, why the charge was upheld, and what the decision means for banks and lenders, borrowers, purchasers, and spouses in polygamous marriages. It also answers a related question we often hear: Are shares in a company matrimonial property, and can a spouse stop their sale?

What is spousal consent?

Spousal consent is the written, informed agreement of a spouse to a transaction that disposes of, or encumbers, matrimonial property: a sale, transfer, lease, gift or charge (mortgage). It exists because a spouse may hold a beneficial interest in matrimonial property even where only the other spouse’s name is on the title deed. In practice, the spouse signs the charge or transfer instrument, or a separate spousal consent form or affidavit, before an advocate. Where consent is required but not obtained, the non-consenting spouse may ask the court to set the transaction aside.

Which laws govern spousal consent in Kenya

The relevant provisions should be read together:

1. Constitution, Article 45(3): provides for equality of spouses at marriage, during marriage and at dissolution.
2. Land Act, section 79(3): a charge for a matrimonial home is only valid if executed by the chargor and any spouse of the chargor living on the matrimonial property.
3. Land Act, sections 90, 96 and 97: default notices and notice of sale must be served upon the spouse of the chargor who gave consent.
4.  Land Registration Act, s. 28: Spousal rights over matrimonial property are overriding interests, binding registered land without being noted on the register.
5. Matrimonial Property Act, sections 2, 6, 7, 8, 9 and 14: definitions, ownership, polygamous property arrangements, contributions and rebuttable presumptions.
6. Matrimonial Property Act, section 12: restrictions and protections concerning matrimonial property and the matrimonial home.
7. Land Registration Act, section 93: land acquired during marriage for the co-ownership and use of both or all spouses is dealt with under the Matrimonial Property Act.

What counts as matrimonial property

Section 6(1) identifies matrimonial homes, household goods and effects in those homes, and other movable and immovable property jointly owned and acquired during marriage. Joint ownership is not limited to two names on a title: section 14 creates rebuttable presumptions concerning matrimonial property acquired in one spouse’s name or in joint names.

Sections 2, 7 and 9 also require attention to contribution, including recognized non-financial contributions and contributions to improvements. Conversely, an asset acquired during marriage does not, without further analysis, settle every ownership claim. Separate property and trust property require distinct treatment.

For the differences between joint tenancy and tenancy in common, see Co-owning Property in Kenya. Check the co-ownership structure and matrimonial beneficial ownership before proceeding with a transaction.

When is spousal consent required?

Only when the transaction deals with matrimonial property. Property acquired or inherited before marriage, and trust property (including property held in trust under customary law), is not matrimonial property (sections 5 and 6(2) of the Matrimonial Property Act). In Resma Commercial Agencies v Ngattah [2025] KECA 2214 (KLR), the Court of Appeal held that where a spouse fails to prove a beneficial interest in the property, her consent is not needed, even where the family lived there for years. We analyse that decision in detail in our Ultimate Guide to Spousal Consent.

What were the facts in Kageni v Bank of Africa (K) Ltd & 3 others (Civil Appeal 186 of 2018) [2026] KECA 1921 (KLR)

United Brothers Camps Ltd obtained banking facilities of KShs. 20.6 million from Bank of Africa (K) Ltd. Humphrey Mbabu Mbaka provided L.R. No. Chuka Township/39 as security under a charge dated 7 August 2012. Humphrey and Lucyline Kanyua Mutindwa presented themselves as husband and wife residing on the property. Lucyline gave spousal consent and participated in the guarantee arrangements.

The loan fell into arrears in 2013, was restructured, and then defaulted again. The bank served a statutory notice under section 90 of the Land Act (3 February 2015) and a notice to sell under section 96 (21 May 2015), copied to Lucyline, and instructed Muga Auctioneers (the 2nd respondent) to sell. By 7 July 2015, the bank claimed over Kshs 38.2 million.

Elyjoy Kageni learned of the sale from a newspaper advertisement around 29 July 2015, and she sued, challenging the proposed sale, maintaining that she was Humphrey’s first wife under Meru customary law and had not consented to the charge under section 79(3) of the Land Act. The bank responded that it had never heard of her, that the only spouse it knew of was Lucyline, and that Elyjoy did not live on the property.

The Environment and Land Court at Chuka dismissed her claim on 27 June 2018, holding that Elyjoy had not proved she was a wife; that having a child with a man (she relied on her son’s birth certificate) does not make a woman his spouse; and that her evidence was contradictory. He also found no evidence that she lived on the land. On the law, he held that section 79(3) speaks of “any spouse”, not “all spouses”, so a second spousal consent was unnecessary: had Parliament intended every spouse to consent, it would have said “all”. She appealed.

What issues did the Court of Appeal determine?

The appeal was heard by S. ole Kantai, J.W. Lesiit and A.O. Muchelule, JJA, who framed three issues:

1. whether the appellant established that she was married to the 4th respondent;
2. whether the bank met its obligation as chargee to obtain spousal consent before the charge, and served the required notices; and
3. whether the appellant was entitled to a permanent injunction stopping the sale.

These were separate questions. Establishing that a claimant is a spouse does not, by itself, establish that a particular charge is invalid or that an injunction must follow.

Did the Court recognise Elyjoy as a lawful wife?

Yes. The Court disagreed with the trial court’s rejection of her marital status. It considered evidence of the customary union, family recognition, and the husband’s other relationships, and found that she had established marriage under Meru customary law. Her evidence on that issue had not been controverted.

The Court referred to VRM v MRM & another [2006] KECA 342 (KLR) and the presumption-of-marriage reasoning in Hortensia Wanjiku Yawe v Public Trustee, Civil Appeal No. 13 of 1976. The conclusion was that a child’s birth certificate alone does not prove a marriage.

Which wife did the Court of Appeal say must consent to the charge?

The wife living on the charged property. The court acknowledged this was “not an easy question” because the law does not mention polygamous marriages. It then focused on the operative words of section 79(3): the charge must be executed by the chargor and any spouse of the chargor living in that matrimonial home. The court found that Elyjoy’s consent was not required, for these reasons:

1. she was not living on the suit land and had never lived there; her son lived there with his father and Lucyline;
2. she did not know of the loan or of the bank until the auctioneer’s notice;
3. the bank was unaware of her existence, because the husband never disclosed her; and
4. in those circumstances it would be “unreasonable and unjust” to expect the bank to find her.

The bank, on the other hand, had satisfied itself that Lucyline was a wife living on the property, and she had signed the spousal consent. That complied with section 79(3).

So, which spouse must consent to a charge in a polygamous marriage?

On the authority of Kageni v Bank of Africa (K) Ltd & 3 others, the consent that validates a charge of a matrimonial home under section 79(3) of the Land Act is that of the spouse or spouses living on the property being charged. Where two or more wives live on the same property, each of them should sign. A wife who lives elsewhere, and whose existence the lender neither knew nor had reason to know of, cannot invalidate the charge simply because she was not asked.

Three cautions apply. First, the decision turns on its facts: a bank that knows of another wife, or ignores obvious signs of one, may not get the same protection. Second, the court did not decide whether the non-resident wife has a beneficial interest in the property, which she may still pursue against her husband. Third, as the court observed, the statutes are silent on polygamous marriages, so the question may yet reach the Supreme Court or prompt legislative reform.

Does the Matrimonial Property Act require the consent of all wives?

Not expressly. Section 12(1) prohibits alienation without “the consent of both spouses” but only “during the subsistence of a monogamous marriage”. Section 12(5) requires both spouses’ consent to mortgage “the matrimonial home”, which section 2 defines by reference to the property the spouses occupy or use as their family home. A wife who never lived on a property will struggle to show it is her matrimonial home. What the Act does give every wife in a polygamous marriage is the right under section 12(2) to protect her interest by a caveat or caution. A caution on the register puts every lender and purchaser on notice.

What are the major takeaways for lenders, borrowers, purchasers and spouses?

How can a non-resident wife protect her interests after this decision?

1. Register a caution against the title under section 12(2) of the Matrimonial Property Act read with the Land Registration Act.
2. Register the customary marriage under the Marriage Act, 2014, so that her status can be proved by certificate rather than oral evidence. See our guide to Marriage Law in Kenya and Why Most Kenyan Spouses Are Not in Valid Marriages: The Legal Gap in Customary/Traditional Marriages
3. Act early. Elyjoy’s application for a temporary injunction was dismissed in March 2017, and the charge had been registered for three years before she learned of it. A caution lodged before the charge would have changed the position.
4. Pursue her husband separately. A failed challenge against the lender does not extinguish any claim she has against her husband for a declaration of her beneficial interest under section 17 of the Matrimonial Property Act.
