(ii) WHETHER THE SIGNATURE OF THE DECEASED IN THE 2011 WILL IS A FORGERY P-02(NCVC)(W)-503-03/2024 44 [32] After addressing the expert evidence of SP3, a forensic handwriting expert, who analysed the signature and concluded it was forged, while the Ds did not provide expert testimony to refute SP3's findings. The learned JC found SP3's testimony unconvincing due to the limited number of signature samples provided (only four, mostly photocopies) and the supposed outdated methods used for analysis. He emphasised that expert testimony is opinion-based and not conclusive. It must be supported by cogent data and corroborated by other evidence, and it must be ruled that the signature of the deceased was not proven to be forged. [33] It is a trite legal position that due execution cannot be equated with knowledge and approval of the contents (Williams, Mortimer and Sunnucks on Executors, Administrators and Probate, 18th Edition, 2000), as it is for the party propounding the impugned Will to prove the existence of knowledge and approval of the testator concerning the impugned Will. [34] Since we have determined legal infirmity in the learned JC's findings regarding the understanding and knowledge addressed in paragraph above, this issue is rendered academic; consequently, it goes without saying that the nature of the signature on the 2011 Will does not remedy its invalidity. (emphasise is ours) [35] Our determination herein to set aside the learned JC’s impugned decision effectively and immediately sets aside the 2011 Will. Consequently, it restores the existence of the 1976 Will as if it had not been revoked by the 2011 Will as claimed. With the same P-02(NCVC)(W)-503-03/2024 45 reasoning above, we also hereby order that the counterclaim filed by R2 is dismissed with costs payable to all the Ps. [36] In the foregoing circumstances, we find it just and equitable to allow the Ps’ claim, as set out in paragraph 27, PDF pp.140-143, SoC, L4, Appeal Record A. For convenience, they are summarised in a nutshell as follows:
