If the person against whom an informal instrument is presented denies that the handwriting, signature, signature stamp or fingerprint attributed to him is his, or his successor or representative denies the same or denies knowing of the instrument, and the opposing party insisting on relying on the informal instrument which has a bearing on the dispute, and the facts and documents of the case are not sufficient to convince the court of the veracity of the handwriting, signature, signature stamp or fingerprint, then the court shall order verification by comparison and/or testimony of witnesses, pursuant to the rules and procedures stipulated in the present Law. However, witnesses may be heard only with respect to proving that the handwriting, signature, signature stamp or fingerprint has been affixed to the instrument.
