we have 2 property and both of them are on my grandmothers name. She passed away 1 yr back and there is no will from her. Now we are living in one property and in another property my uncle is living however my uncle has passed away long back. The problem is now that property is not divided and no family tree(pedhi namu) is done and uncle's son is asking for his share in property. there is no contribution from him in this property coz my father raise them all by them own and now he is asking for share. how can we resolve this issue.
