Why DNA Tests Cannot Be Forced in Succession: Understanding the High Court's clarification on proving paternity during inheritance disputes.

In a landmark ruling delivered in early 2026, the High Court of Kenya (Family Division) settled a recurring controversy: can a party in a succession dispute compel another person (or the deceased's remains) to undergo DNA testing to prove or disprove paternity? The answer, according to the court, is no – not without consent or a very narrow exception. This decision has profound implications for inheritance battles where the status of a purported child is contested. This article explains the ruling, its reasoning, and what it means for families in Machakos and beyond.

Key case: In re Estate of Mwangi (Succession Cause No. 247 of 2023) [2026] eKLR, the High Court held that ordering a DNA test over objection violates the right to privacy (Article 31) and bodily integrity (Article 28) of the living, and post‑mortem sampling of the deceased requires prior court order only if there is already strong prima facie evidence of tampering.

The Legal Framework – When Can DNA Be Compelled?

Under Section 76 of the Evidence Act (Cap 80), courts have discretion to order medical examinations, including DNA tests, in civil matters – but this discretion is not absolute. The High Court in 2026 clarified:

Consent is paramount: A living person cannot be forced to give a DNA sample solely because another party in a succession case wants to prove they are not the biological child of the deceased. Refusal to consent cannot be used as an adverse inference against them.
Deceased's samples: Exhumation or sampling from stored pathology specimens requires a court order, which will only be granted if there is compelling evidence of fraud in the paternity claim (e.g., forged birth certificates or multiple conflicting claims by the same "child").
Best interest of the child: If a child's inheritance is at stake, the court may order DNA testing over a parent's objection only if the test is minimally invasive and the child's welfare (including psychological impact) is carefully assessed.

What This Means for Inheritance Disputes

Before this ruling, some advocates would file applications to compel DNA tests routinely, hoping to disqualify claimants. Now, the court expects parties to rely on other evidence first:

Birth certificates and hospital records.
Affidavits from relatives, neighbours, and school records.
Recognition by the deceased during their lifetime (e.g., maintenance payments, name mentioned in a will).
Customary acknowledgment (e.g., introduction to the extended family).

Important: The ruling does not prevent voluntary DNA testing. If a claimant agrees to take a test, the results are admissible. But no one can be forced.

Practical Advice for Administrators and Beneficiaries

If you suspect a false claimant: Gather documentary and circumstantial evidence first. Only then, file a formal application showing a prima facie case of fraud – the court may then order a limited investigation, possibly including DNA if no other way to resolve.
If you are asked to take a DNA test: You have the right to refuse. However, consider that refusal may strengthen the other party's argument that they are being truthful. Consult a lawyer before refusing or consenting.
If you are the administrator: Do not distribute estate assets until all legitimate dependants are identified. If there is a genuine dispute over paternity, apply to court for directions.

"The rush to DNA has sometimes been used as a harassment tool – forcing elderly relatives into invasive tests or digging up graves with little justification. This ruling restores dignity and privacy to succession proceedings." — Naomi Mutinda, Succession Advocate
