JOO v MBO & 2 others
The bottom line
#Pre-2013 divorce property claims use old law; no automatic 50:50 split; contribution must be proven.
What this practically means
#The Supreme Court ruled that for divorce cases filed before 2013, the old Married Women's Property Act applies. The Constitution's equality clause does not mean automatic 50:50 split. Each spouse must prove their contribution to get a share. Indirect contributions like caring for home or paying school fees count. The wife in this case proved her contributions and got 50% of the property. The husband's appeal was dismissed.
Executive summary
#Questions the Court framed

- 3.Whether article 45(3) provides for proprietary rights and whether the said article can be a basis for apportionment and division of matrimonial property on a 50/50 basis without parties fulfilling their obligation of proving what they are entitled to by way of contribution.
- 4.What relief is available to the parties including on the issue of costs?
Key legal issues
#What is the applicable law for division of matrimonial property in a suit filed before the Constitution, 2010 and the Matrimonial Property Act, 2013?
The applicable law is the Married Women's Property Act, 1882, and the principles in Echaria v Echaria remain good law for such claims. The Matrimonial Property Act, 2013 does not apply retrospectively.
The Supreme Court applied the general rule against retrospective application of statutes from Samuel Kamau Macharia & another v KCB & 2 others, noting that the Matrimonial Property Act, 2013 does not contain express words or necessary implication for retrospective effect. The Court also relied on section 23(3) of the Interpretation and General Provisions Act, which preserves rights and proceedings under repealed laws. However, the Court distinguished the Constitution, holding that Article 45(3) can be applied retrospectively because its language does not bar such application and a Constitution is not subject to the same principles against retroactivity as ordinary legislation.
Does Article 45(3) of the Constitution provide for proprietary rights and can it be a basis for automatic 50:50 division of matrimonial property?
Article 45(3) does not vest proprietary rights or create an automatic 50:50 division. It guarantees equality, which means each party is entitled to a fair share based on proven contribution, not an automatic equal split.
The Court reasoned that Article 45(3) deals with equality of fundamental rights, not redistribution of property. It protects the right to property under Article 40. The Court approved the reasoning in Echaria that marriage alone does not entitle a spouse to a beneficial interest. It also adopted the persuasive opinions of Kiage JA in PNN v ZWN and Tuiyott J in UMM v IMM, which held that equality does not translate to automatic 50:50 division. The Court emphasized that contribution, whether direct or indirect, must be proven, and the division must be fair and equitable based on the circumstances of each case.
What constitutes contribution for purposes of division of matrimonial property under the Married Women's Property Act, 1882 and Article 45(3)?
Contribution includes both direct monetary contribution and indirect non-monetary contribution, such as taking loans for family expenses, paying school fees, and contributing to the welfare of the home. The extent of contribution is assessed on a case-to-case basis.
The Court reviewed the evidence, including loan application forms and the respondent's employment history, and agreed with the Court of Appeal that the respondent had proven contribution. The Court cited Burns v Burns for examples of indirect contribution, including contributing to family expenses and caring for the home and children. The Court held that the Court of Appeal properly analyzed the evidence and found that the respondent's contributions, including loans for school fees and construction, entitled her to a 50% share. The Court rejected the appellant's argument that only direct financial contribution counts.

#Setting aside the Court of Appeal decision and substituting it with one allowing the appeal
The Supreme Court found no reason to fault the Court of Appeal's finding based on its analysis of the evidence and the law.
Order awarding the respondent 10% share of Nairobi/Block 97/564 and 10% share of rental units
The Court found the 50:50 division reasonable in the specific circumstances of this case based on the evidence of contribution.
Order declaring that the law to be considered is the law in force at the date the suit was lodged
While the Court held the Married Women's Property Act, 1882 applies to claims filed before the Matrimonial Property Act, 2013, it also held that Article 45(3) of the Constitution applies retrospectively and the Court of Appeal's decision was based on evidence of contribution, not solely on the applicable statute.

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.
We have come to the conclusion that there is no retrospective application of the Matrimonial Property Act and hold that the applicable law to claims filed before the commencement of that act is the Married Womens Property Act, 1882.
The equality provision in article 45(3) does not entitle any court to vary existing proprietary rights of parties and take away what belongs to one spouse and award half of it to another spouse that has contributed nothing to its acquisition merely because they were or are married to each other.
The stated equality under article 45(3) means that the courts are to ensure that at the dissolution of a marriage, each party to a marriage gets a fair share of the matrimonial property based on their contribution.
We therefore find that the test to be applied to determine the extent of contribution is ultimately one of a ‘case to case basis’
The petition of appeal dated and filed on July 3, 2020 is hereby dismissed.
The appellant shall bear the respondents’ costs.

#Practical implications
#Retroactivity and contribution proof
Advise clients with pre-2013 claims that the Married Women's Property Act 1882 governs, not the 2013 Act. Gather evidence of both direct and indirect contributions. Article 45(3) does not guarantee 50:50; you must prove contribution on a case-by-case basis. The Supreme Court rejected automatic equal division.
Matrimonial property division risks
If your business is involved in a matrimonial dispute filed before 2013, note that indirect contributions (e.g., loans for business, paying school fees) can entitle a spouse to a share. Ensure clear documentation of ownership and contributions. The court will assess each case individually.
Prove your contribution to get fair share
If you are divorcing and filed your case before 2013, you must prove your contribution to property. Keep records of financial and non-financial contributions like homemaking or paying bills. Marriage alone does not give you half. The Supreme Court confirmed that indirect contributions count.
