This discussion concerns a legal dispute over a witness's signature on a will deed. The plaintiff requested an expert opinion to compare the signature, but the trial court dismissed the application as belated. The witness themselves testified that they were not present during the will's execution and that their signature was forged. The chances of the plaintiff succeeding in a higher court are considered slim, as direct oral evidence from the witness carries more weight than expert opinion, and proving the signature alone doesn't guarantee the will's validity.
