Many Kenyans believe that living together for six months or several years automatically makes them “husband and wife” in the eyes of the law. This belief, often tied to the concept of presumption of marriage Kenya, is a dangerous legal fallacy. While you might share a bed, a kitchen, and even a mortgage, the law does not view your “come-we-stay” arrangement with the same protective lens as a registered marriage. When the relationship ends or a partner passes away, the lack of a marriage certificate often leaves the vulnerable party with nothing.
In Kenyan law, a marriage is a voluntary union between a man and a woman, registered under the Marriage Act 2014. The doctrine of presumption of marriage is a common law tool used by courts to infer a marriage exists when there is long cohabitation and a public reputation of being a couple.
However, recent rulings from the Supreme Court of Kenya have made it harder to claim this status. In the landmark case of [Mary Nyambura Kangara v Paul Ogari Mayaka] [2023] [eKLR] Petition 9 of 2021, the court clarified that long cohabitation alone does not create a marriage. Parties must also prove they had the legal capacity to marry (they weren’t married to others) and a clear intention to be husband and wife.
Living together for years is merely evidence; it is not a legal guarantee of marital status.
The Matrimonial Property Act 2013 is the primary law governing assets in a home. It explicitly defines “matrimonial property” as assets acquired during the subsistence of a marriage. If you are in a cohabitation arrangement that hasn’t been legally “presumed” by a court, this Act does not apply to you.
Without the protection of this Act, you cannot automatically claim a 50/50 split of the home or the family car. Instead, you fall under the general principles of property law, where the person whose name is on the title deed or logbook is often seen as the absolute owner.
The Matrimonial Property Act 2013 only protects those in a legally recognized or successfully presumed marriage.

One of the greatest benefits of being a spouse is the recognition of “indirect contribution.” This includes domestic work, childcare, and farm work as a basis for owning a share of property. Under Section 7 of the Matrimonial Property Act, these non-monetary efforts are valued.
For unmarried partners, proving these contributions is a nightmare. In the absence of a marriage, the court often looks for “direct financial contribution.” If you spent your salary on groceries and school fees while your partner paid the mortgage and put the house in their name, you might find yourself with no “proprietary interest” in the house. You would have to rely on complex “Trust” laws to prove you have a claim, which is a costly and uncertain legal battle.
Without a marriage, your non-monetary work at home may not count toward owning a share of the property.
A common reason why the presumption of marriage Kenya fails in court is the issue of “capacity.” If one partner is still technically married to someone else (even if they have been separated for 20 years), no new marriage can be presumed.
In the eyes of the law, you are simply “cohabiting” or “staying together” for companionship. This was the situation in the Kangara v Mayaka case, where the court found that despite 25 years of living together, a marriage could not be presumed because the legal hurdles of intention and capacity were not met.
You cannot be a “presumed spouse” if either party is still legally tied to another marriage.

If you are in a long-term cohabitation, hope is not a strategy. You must take proactive steps to secure your financial future:
Documentation and joint registration are the only true safeguards for unmarried partners in Kenya.
The presumption of marriage Kenya is becoming a legal relic. The courts are moving toward a stricter interpretation that favors formal registration and clear proof of contribution. To avoid losing your life savings in a breakup or a succession dispute, move away from the “come-we-stay” myth and move toward legal certainty.
