getting back joint family's property

It depends, if your father has purchased the joint property in his name and with his own funds individually , the property is said to be transfered to him under his own name and can be called as his own property.

My father had a appeal since four years and now he got back the said property in the name of my Grandfather with his own efforts and with his own funds without getting help of income of the joint family's other members and the other members have given unregistered notary bond pertaining the fact in the name of my father but the Talathi in mutation entry on 7/12 entered all the names of the said joint family members including my father but as the said lost joint property had got back by my father without getting help of income of other members of the said family it falls under the category of independent income of my father. Now what can be done to delete the names of other members of the said family from the said 7/12and enter the said property as independent property in the name of my father only on the said 7/12 please give experts opinion

In this said case can section 22 of the hindu varasa Kayada 1956 apply please give experts opinion

The said property is yet undevided

It is felt that;

IT may vest back in Title holder say; Grandfather as per your query, if he is alive

Or in legal heirs of Title holder say; Grandfather, as per provisions of personal law that applies.

The expenses etc should be ideally shared by all that shall benefit.

IT is their personal matter.
