Single heir of property

No. not now. You and your siblings can claim share in the property.

Yes, your father is the absolute owner and he can dispose off the same according to his wishes.

@ Adv Archana - After my grandfather's death even if there is no other than my father to inherit the property, the property is not his absolute property?? then when can he become absolute owner?

Your father has inherited the property from his father by succession. He could have disposed it off before your birth or the birth of your siblings, it would have been absolutely legal for him to do so for he being the sole heir at that time. But if he has not disposed it then, now you and your siblings can claim share.

Ok. He did not dispose it off then but he his name was on city survey records as sole owner..so desposing means selling out or just registering on his name??

@ Archana garu,

As per Section 8 of Hindu Succession Act, son is a legal heir to succeed to his father but not son's son.  The property succeeded by the son would become his own property but not joint family property to share along with his children.

So after codification of Hindu Law, your statement will not hold good.

I differ here and stick to my earlier posts, as the father had inherited the property from his father by succession. Property inherited from paternal ancestors is ancestral property in the hands of a person vis-a-vis his own children. So the children of such a person has a share in the property.

@ Archana garu,

pls go through "AIR 1986 SC 1753"
