A will that fails on formalities can be as bad as no will at all , the family ends up in the intestacy queue anyway. Kenya’s requirements are not onerous, but they are strict, and they are applied.

What makes a will valid in Kenya?
The Law of Succession Act (Cap 160) prescribes the formalities. In summary: the person making the will , the testator , must have capacity and be of the age of majority; the will must be in writing and signed by the testator, or by someone signing in the testator’s presence and at the testator’s direction; and the signature must be made or acknowledged in the presence of two or more competent witnesses, who attest and sign in the presence of the testator.

Who can make a will in Kenya?
Any adult with capacity can make a will. Capacity means understanding what you own, who would naturally benefit, and what the will actually does. A will procured by fraud, made under pressure, or made at a time of failing capacity is vulnerable to challenge, which is why careful, unhurried execution matters as much as the drafting itself.
What mistakes complicate Kenyan wills?
- witnessing that was rushed, or witnesses who were not present with the testator as the Act requires;
- informal documents , notes, recordings or drafts , relied on as if they were wills;
- ambiguity about which assets are covered, particularly for land described without clear references;
- failure to update after marriage, which can revoke a will.
Does a will need to be registered in Kenya?
There is no compulsory registry for wills in Kenya. Safe custody is the practical issue: the original must be locatable after death, and the executor or family should know who holds it. Many testators deposit the original with their advocate or a bank, and tell one trusted person where it is kept , an unlocatable original helps nobody.
The formalities are the floor, not the ambition: a well-drafted will also anticipates execution, minors and contingencies. CS Advocates LLP drafts wills and advises on their safekeeping and review; see our practice areas or read more about the firm.
