proof affidavit has stated about the name of the scribe or the attestor, who were present during the execution of Exhibit A2. During the course of cross examination of PW-1, (plaintiff), he stated that one Nachimuthu, was the scribe and PW-2, Eswaran was present as witness. In the course of cross examination PW-1, candidly admitted that neither PW-2 nor the said Nachimuthu have affixed their signatures in Exhibit A2. The Trial Court, in my view, rightly held that Exhibit A1 & Exhibit A2, are unregistered documents and the defendants having denied their signatures in Exhibit A2, the onus is on the plaintiff to prove the execution of Exhibit A2. The Trial Court also noted that the plaintiff took no steps to compare the signatures, seek for any expert opinion and in the absence of signatures of the scribe or the attestor and with no pleadings to the said effect, the Trial Court rejected the evidence of PW-2, as it is not safe to rely upon the Exhibit A2.
