Please give practical answer. It was the year 1955. My father was a minor at that time. Now he is 75 years old. No bank was available in that area at that time and his maternal uncle is no more. It is not possible to find any document related to scholarship. Those who know the fact that he was getting scholarship in the family are no more except his brother himself who is opposite party.
Even if the maternal uncle of your father is alive today, he cannot claim the property on any basis including by producing the scholarship grant order, because it is not a benami transaction nor maintainable due to passage of such a long period of more than 60 years.
Therefore your father's brother has no reason or ground for any claim in the property.
The court will not answer to his frolies or gimmicks.
Ask him to approach court with his untenable claim, he will lose his time, money and energy due to his greedy act.
