hai,
my grand father has 2 sons,the 2nd son is my father, both of these sons shared some agriculture lands equally, to my father the land given was away from road ,so my grand father made the 1 st son write a agreement about the way to my land through his land giving my father full rights. the agreemant was made on paper and the 1st son signed on one ruppee register stamp, and witnessed by his son. now the 1st son is expired, and his propety inherited to his son.
how valid is the agreement they made on paper and signed on one rupee stamp? how much right do the 2 nd brother have?
