In Adam vs. Ikhano (1988) 4 NWLR (Pt. 89) 478 it was held that where there is a dispute as to the validity of a WILL, the primary onus of proof is on the party who propounds it to show clearly that prima facie it is duly executed. Once the primary onus is discharged, the secondary onus of proof of the allegation that the WILL is not properly executed or that it is tainted with fraud or forgery shifts unto the party challenging its proper execution to substantiate his allegations. See also Omorhirhi vs. Enatevwere (1988) 1 NWLR (Pt. 73) 476 and Okoli vs. 1st Bank (1986) 5 NWLR (Pt. 46) 1052.
ANYWHERE THE SIGNATURE APPEARS IN A WILL, IS VALID; POSITION OF SIGNATURE IS IMMATERIAL
As regards the contention that failure of the Testator to sign the Will at the right place invalidates the Will, I wish to refer to Section 4(1)(d) of the Wills Law (Supra) wherein the concluding part of the section states: “… but no form of attestation or publication shall be necessary”. Section 4 of Wills Law of Lagos State is in pari material with Section 9 of the English Administration of Justice Act, 1982 and the Authors of Williams on Wills at page 95 have interpreted the provision to mean ‘that there is no longer any formal requirement that the signature should be at the foot or end of the Will but in so long as it is apparent’ in the face of the Will that the Testator intended by his signature to give effect to the Will. It has been held that a Will is not invalidated simply because the Testator’s signature appears in the Attestation or Testimonium clause. See Re Moores Goods (1901) P.44. Therefore, the submission of counsel for the Appellants that the Will is unsigned because the attestation clause is blank is not tenable in so for as there is a signature by which the Testator intends to give effect to the writing signed as his Will. I think the Testator’s signature in the Will satisfies this requirement.
