“24.A plaint reading of the aforesaid section shows that if a document is required by law to be attested, it shall not be used as evidence until one attesting witness at least has been called for the purpose of proving its execution, if there be an attesting witness alive, and subject to the process of court and capable of giving evidence. However, it shall not be necessary to call an attesting witnesses in proof of the execution or any document, not being a will, which has been registered in accordance with the provisions of the Indian Registration Act, 1908, unless its execution by the person by whom it purports to have been executed is specifically denied. In this case, the alleged executant namely, Chenniappa Gounder is not alive, the plaintiff is one of his sons, he is denying the execution of the said document by his father. So, in view of the aforesaid provision of law atleast one of the attestors should have been called for the purpose of proving its execution.”
