Can aunt claim in property received by father through his father

Your query is not clear as to whether you grandfather's property was a self-acquired property or an ancestral property. If it was a self-acquired property and your grandfather passed away in 1973, then according to the recent judgement passed by the supreme court in 2005, your father's sister will not have any share in you grandfather's property. But if your grandfather's property was an ancestral property then your father's sister will have share in the property. Your father's sister share in the property has nothing to do with the year in which she got married.
