Dear Sir,
It is better to file a partition suit and also file a injunction suit against your father that not to sale the property.
The court may order grant a temporary injunction to restrain such act, or make such other order for the purpose of staying and preventing the wasting, damaging alienation, sale, removal or disposition of the property as the court thinks fit until the disposal of the suit or until further orders.
Dear Sir,
After the death of your grand father it naturally devolves on the following formula
Section 8 in The Hindu Succession Act, 1956
- General rules of succession in the case of males.—The property of a male Hindu dying intestate shall devolve according to the provisions of this Chapter—
(a) firstly, upon the heirs, being the relatives specified in class I of the Schedule;
(b) secondly, if there is no heir of class I, then upon the heirs, being the relatives specified in class II of the Schedule;
(c) thirdly, if there is no heir of any of the two classes, then upon the agnates of the deceased; and
(d) lastly, if there is no agnate, then upon the cognates of the deceased.
