According to the courts, matrimonial property is not shared by default but it is earned through contribution.
When JOO and his estranged wife, MBO, went separate ways in 2008, their dispute over property reflected a debate now echoing in courts: Does marriage automatically entitle a spouse to half of everything?
The Court of Appeal and later the Supreme Court, delivered a firm answer—No.
According to the courts, matrimonial property is not shared by default but it is earned through contribution.
While the law recognises both financial and non-financial input, including domestic work and emotional support, a spouse must still prove such contribution.
The judges have also emphasized that equality does not mean duplication. A spouse who invested money, acquired land, or developed assets cannot be stripped of half simply because they married.
Likewise, a homemaker who sacrificed career opportunities to raise children or run the household should not walk away empty-handed—but they must demonstrate effort, not entitlement.
Before the JOO vs MBO case, courts used to be guided in settling matrimonial disputes by a matter that was determined in 2007 by a bench of five judges of the Court of Appeal.
The matter, famously known as Echaria vs Echaria, was a property fight between Mr Peter Mburu Echaria, a former diplomat and his estranged wife Priscila Mburu Echaria.
After their acrimonious divorce case in 1993, the High Court granted Ms Echaria, who died in January 2019 aged 83, an equal share of their 118-acre Tigoni Farm.
Then, the High Court used Section 17 of the Married Women’s Property Act, 1882, which provided that the property bought during marriage, was presumed co-owned and in case of divorce, should be sold and the net proceeds shared equally.
Distribution based on contribution
Mr Mburu appealed the ruling and in February 2007, appellate court judges Philip Tunoi, Emmanuel O’kubasu, Erastus Githinji, Philip Waki and William Deverell delivered a decision that would change the property sharing debate.
The court went on to find that for a wife to be entitled to a share of the property that is registered in the husband’s name, she had to prove contribution towards acquisition of that property.
The judges further said the distribution should be based on contribution made by each party.
Similarly, Court of Appeal judge Patrick Kiage had in a 2017 concurring decision warned that, “The reality remains that when the ship of marriage hits the rocks, flounders and sinks, the sad, awful business of division and distribution of matrimonial property must be proceeded with on the basis of fairness and conscience, not a romantic clutching on to the 50:50 mantra.”
The judge added that it was not a “matter of mathematics merely as in the splitting of an orange in two for, as biblical Solomon of old found, justice does not get to be served by simply cutting up a contested object of love, ambition or desire into two equal parts..”
Section 7 of the Matrimonial Property Act states that; “Subject to section 6(3), ownership of matrimonial property vests in the spouses according to contribution of either spouse towards its acquisition, and shall be divided between the spouses if they divorce or their marriage is otherwise dissolved.”
FIDA challenged the said section in 2018, arguing that parties to a marriage are entitled to equal rights as per the constitution.
The petition was, however, dismissed by the High Court stating that if the request was allowed, it would create a “loophole for fortune seekers” to benefit from their spouse’s success in case of a divorce.
In the Echaria case, the court stated that where the disputed property is not registered in the joint names of the parties to the marriage, but is registered in the name of one spouse, the beneficial share of each spouse would ultimately depend on their proven respective financial contributions, either directly or indirectly in the acquisition of the property.
The Court of Appeal ruled that marriage alone does not confer ownership rights, and that a spouse must demonstrate their direct or indirect input—whether through financial investment, homemaking, childcare, or emotional support.
The court added that for a wife to be entitled to a share of the property that is registered in the husband’s name, she had to prove contribution towards acquisition of that property.
Courts have stated that contribution should be interpreted broadly, acknowledging that unpaid domestic work is just as valuable as financial input, but must still be proven.
The bench presided by Deputy Chief Justice Philomena Mwilu said Article 45(3) of the constitution acts as a means of providing for equality as at the time of dissolution of marriage but such equality can only mean that each party is entitled to their fair share of matrimonial property and no more.
“Nowhere in the Constitution do we find any suggestion that a marriage between parties automatically results in common ownership or co-ownership of property (hence vesting of property rights) and Article 45(3) was not designed for the purpose of enabling the court to pass property rights from one spouse to another by fact of marriage only,” the apex court said.
The judges added that the guiding principle, again, should be that apportionment and division of matrimonial property may only be done where parties fulfill their obligation of proving what they are entitled to by way of contribution.
The apex court stressed that article 45(3) of the constitution was intended to promote fairness in matrimonial property distribution at the point of dissolution.
Equality in that context, said the judges, meant equitable entitlement based on demonstrated contribution, not automatic entitlement to half of the property.
The judges added that equity denotes that a party, though having not contributed more resources to acquiring the property, may have nonetheless, in one way or another, through their actions or their deeds, provided an environment that enabled the other party to have more resources to acquire the property.
“This is what amounts to indirect contribution. Equity therefore advocates for such a party who may seem disadvantaged for failing to have the means to prove direct financial contribution not to be stopped from getting a share of the matrimonial property,” said the judges.
The Supreme Court stated that to hold that Article 45(3) has the meaning of declaring that property should be automatically shared at the ratio of 50:50 would bring huge difficulties within marriages,
“Noting the changing times and the norms in our society now, such a finding would encourage some parties to only enter into marriages, comfortably subsist in the marriage without making any monetary or non-monetary contribution, proceed to have the marriage dissolved then wait to be automatically given 50percent of the marital property. That could not have been the intention of our law on the subject,” said the judges.
