defendant-appellant. Consequently, adverse presumption arises against the defendant. Oral statements of defendant and his relatives are not sufficient to prove the date of birth of the defendant to depict his minority at the time of execution of pronote and receipt in question, in the absence of any documentary evidence regarding the date of birth of the defendant. It may be added that Surjit Singh DW-2 stated that defendant had studied upto 5th /6th standard. However, even school record has not been produced to prove date of birth of the defendant and consequently to prove his minority at the time of pronote and receipt in question. On the other hand, defendant had also executed some mortgage deed dated 03.03.2003 and sale deed dated 04.12.2003 and subsequently challenged the same on the ground of being minor at the time of execution of the said documents, but he did not succeed.
