AAG v MI alias GKK (Civil Appeal E086 of 2022) [2026] KECA 239 (KLR)
The bottom line
#Kenya's Court of Appeal ruled matrimonial property is divided by proven contribution, not automatic 50:50 sharing, and older cases follow pre-2013 law.
What this practically means
#Executive summary
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Whether the learned Judge was biased for having heard an appeal from the Kadhi's Court in respect of the same parties and so ought not to have heard and determined the Originating Summons
- 2.Whether the trial Judge ought to have applied the Married Women's Property Act (repealed) to the circumstances of this case
- 3.Whether the matrimonial property should be divided equally between the parties
Key legal issues
#Raising a new ground of bias for the first time on appeal
The ground of bias was raised for the first time on appeal and was dismissed as there was no determination by the trial court on which to act.
The court noted that the complaint that the Judge ought not to have heard the Originating Summons after hearing the Kadhi's Court appeal was never raised before the trial court. Following the settled rule in Kenya Commercial Bank Ltd vs James Osede, an appellate court should not decide issues raised for the first time on appeal where the other party had no fair notice and where no factual findings exist below.
The applicable statute law governing matrimonial property division
The trial Judge misdirected herself by determining the suit without reference to the Married Women's Property Act 1882 (repealed), under which the Originating Summons was expressly brought; the court would determine the appeal on the basis of that repealed Act.
The Originating Summons was filed on 11th October 2013 invoking the repealed Act, which was the applicable law at the time. Although the Matrimonial Property Act, 2013 had been enacted by the time of the hearing, the Supreme Court in JOO vs MBO held that statute is prima facie prospective and that the Matrimonial Property Act has no retrospective application; claims filed before its commencement are governed by the Married Women's Property Act, 1882, read with Article 45(3) of the Constitution.
Whether only financial contribution counts, or whether indirect/non-monetary contribution entitles a spouse to a share
Division of matrimonial property under the repealed Act rests on the couple's contribution, both financial and indirect or non-financial; the Appellant's contention that only financial contribution matters was dispelled by the Supreme Court's decision in JOO vs MBO.
Relying on Echaria vs Echaria as reaffirmed by the Supreme Court, contribution includes monetary and non-monetary contributions such as domestic work, childcare, companionship, care and management of the matrimonial home, and family business. Equity recognizes indirect contributions that enabled the other spouse to acquire property. However, Article 45(3) does not confer automatic proprietary rights, and mere occupation or duration of marriage confers none.
Whether equal division (50:50) was correct
The trial court's equal division was erroneous; shares must reflect each party's proven respective contributions in the peculiar circumstances of each case, yielding 60:40 for the Nyali property and Nyeri plot, and equal shares of the Nyeri Municipality plot.
On re-evaluation, the Respondent initiated and contributed discernibly to the purchase of the Nyali property, but the Appellant contributed a larger portion of the price, justifying 60:40. The Respondent proved contribution to the Nyeri Municipality plot, which the Appellant failed to prove was bought by his mother; equal shares were warranted. The Nyeri plot was inherited by the Appellant, entitling him to a slightly larger share. The Ruai plot and one motor vehicle were conceded to the Respondent.
The mandate of the Court on a first appeal
The Court on a first appeal is mandated by Rule 31(1)(a) of its Rules to reappraise the evidence and draw its own conclusions, exercising that jurisdiction with caution as set out in Peters vs Sunday Post and Mwangi vs Wambugu.
The court cited the classic statement that an appellate court may review the evidence to determine whether the conclusions of the trial judge should stand, but will interfere where a finding is based on no evidence, on a misapprehension of the evidence, or where the judge has plainly gone wrong or acted on the wrong principle.
Legal principles established
#- Since the Originating Summons was subject to the provisions of the Married Women's Property Act 1882 (repealed), the trial Judge ought to have determined it in accordance with the provisions of the repealed Act; the Matrimonial Property Act, 2013 has no retrospective application.
- Under the Married Women's Property Act (repealed), division of matrimonial properties acquired during the subsistence of the marriage rests on the couple's contribution, both financial and indirect or non-financial, including domestic work and childcare.
- Matters and issues not raised at the trial court cannot be raised for the first time on appeal.

The Judgment of the High Court at Mombasa dated 9th October 2020 be and is hereby set aside.
The Nyali property to be shared with the Appellant to have 60% and the Respondent 40%;
Each party to bear their own costs.
since the Originating Summons was subject to the provisions of the Married Women’s Property Act 1882 (repealed), the trial Judge ought to have determined it in accordance with the provisions of the repealed Act
It is not permissible for matters and issues not raised at the trial court to be raised for the first time on appeal.
The guiding principle, again, should be that apportionment and division of matrimonial property may only be done where parties fulfil their obligation of proving what they are entitled to by way of contribution.
Issues in the judgment
#Paragraph numbering is irregular: the paragraph following paragraph 34 is numbered '25.' before the sequence resumes at 36, indicating a typographical numbering error in the judgment.
The Appellant's grounds of appeal state that the Judge 'erroneously relied on the description of matrimonial property as defined under the Matrimonial Property Act' while the submissions record that the suit was brought under the Married Women's Property Act 1882 (repealed) 'which should have governed division' - the complaint is internally inconsistent with the finding that the Judge applied the Matrimonial Property Act definition of contribution.
