Hello, Greetings of the day!
For the query you posted, I would suggest that:
During the lifetime of the father, he cannot have the right to claim until unless he himself gives him as a gift under love and affection or by will. But he has the right to claim the ancestral property (if any), during the lifetime of his father. Only if your father dies intestate that is without making a will, then you will be entitled to get shares as legal heirs.
In ancestral property: You can claim the property.
In self-acquired property: You cannot claim the property until unless he gifts you under love and affection or by will. If your father dies without making a will, then surely can claim his property as a legal heir.
For better guidance, I will suggest you consult a local lawyer.
Hope it helps
