Procedural Posture

Succession Cause; Probate and Protest to Grant of Probate Based on Written Will / Judgment After Protest Hearing

  1. 1 Whether the written will dated 11.8.2021 was valid
  2. 2 Whether the deceased executed and attested the will in compliance with section 11 of the Law of Succession Act
  3. 3 Whether the deceased had testamentary capacity

Ratio Decidendi

The protestors proved on the balance of probabilities that the impugned will was not executed by the deceased, was improperly witnessed, and failed the formal validity requirements of section 11 of the Law of Succession Act. The court accepted the unchallenged expert evidence that the signature was not the deceased’s and found no contrary evidence from the petitioner. Because the probate was founded on an invalid will, the grant of probate was defective and liable to revocation; intestate succession was therefore the proper course.

Court Disposition

Protest allowed; written will declared invalid, null and void; grant of probate effectively revoked; intestate succession directed

Orders

  • The written will dated 11.8.2021 of Gibson Mwangi Wanjohi is invalid, null and void and was not a will of the deceased.
  • The Protestors shall have costs of Ksh. 75,000 each, payable by the Petitioner.
