Right of elder brother on self acquired property of younger brother

My father purchased property in his name by making payment in cash in court .when he was just above 18 years ,in around 1968 no family member helped him in buying ,so there is nothing mentioned In sale deed about any other family members,it is clearly written in sale deed by the person from whom my father bought that ,the right to sale and use the property belongs to my father and his successor means his wife son or daughter ,.my question is that is there any right of my uncle or his siblings over my property all my uncle is elder to my father ,and they are dead ,their siblings is looking for their right .we are the only one who is taking care of land and property .
