In the Matter of the Estate of Samson Kipketer Chemirmir (Deceased) - Probate and Administration (Validity of Will)
The bottom line
#A will is invalid if it fails to meet the strict legal requirements for witnessing, regardless of how genuine the signature appears.
What this practically means
#Executive summary
#Key legal issues
#Testamentary capacity
The objectors failed to discharge the burden of proving the deceased lacked capacity; evidence showed he discussed and made the will with his advocate.
Section 5(4) of the Law of Succession Act and Section 107(1) of the Evidence Act place the burden of proving incapacity on the objector. No medical evidence was adduced, nor oral or circumstantial evidence to the balance of probabilities. The deceased presented himself at the advocate's office, was guided on documents, and made the will. Re Estate of Gatuthu Njuguna principles were applied.
Weight of expert (document examiner) evidence against eyewitness evidence
The uncorroborated expert opinion that the signature was forged was outweighed by the evidence of the advocate who prepared the will and saw the deceased sign it.
Following Elizabeth Kamene Ndolo, Stephen Kinini Wang'ondu, Kimatu Mbuvi and Vaghella, expert evidence does not trump other evidence and must be weighed in the context of all evidence. The advocate's demeanour, long standing, lack of interest and uncontroverted testimony persuaded the court on a balance of probabilities that the deceased signed the will.
Formal validity - attestation under Section 11(c)
The second witness, Ann Njoki Mathai, did not see the testator sign and received no personal acknowledgement; the will was effectively witnessed by one person only and is invalid.
Section 11(c) requires each of two or more competent witnesses to have seen the testator sign, seen another sign by the testator's direction, or received personal acknowledgement of the signature. Ann admitted she entered after the deceased and Mr. Githua had signed and gave no acknowledgement. The statutory requirement cannot be ignored.
