At least one of the attesting witnesses is required to be examined to prove his attestation and the attestation by another witness and the testator.
Once the Will has been proved then the contents of such document are part of evidence. Thus, the requirement of Section 63 of the Act and Section 68 of the Evidence Act stands satisfied. The witness is not supposed to repeat in a parrot like manner the language of Section 68 of the Evidence Act. [Para No.23]
