the original document would be a safer method by which the Sub Registrar can ensure that the property belongs to the executant. But, that is not the only method. In the case on hand, it is clearly seen that the earlier document was also registered with the very same Sub Registrar and after computerization and digitization, the document is available online for the Sub Registrar to peruse. He can always take an undertaking or a declaration in the form of a sworn affidavit from the vendors to the effect that the original document is with their siblings and register the document. Conduct of an enquiry of the nature that is recommended under Clause (f), extracted supra, would only lead to confusion. If the other legal heirs want to claim exclusive title, it is always open to them to approach the competent Civil Court and if they are able to establish their exclusive right before the Civil Court, the alienation will be invalid. In such circumstances, when the substantive law takes care of and protects any misuse or abuse, we do not think that Rule 55-A of the Registration Rules is the only method by which fraudulent transactions are prevented.
