REGARDING REMEDY IN LAW AVAILABLE AGAINST SALE CONDUCTED DURING PENDENCY OF PARTITION SUIT.

Respected Dignitaries ,
I had filed a suit for partition in the year 2005 against my two brothers who claimed to have right over the property by means of Will Deed and Gift Deed made by my Father (Deceased) . My father had held the property of my Grandfather as a holder of the property and was not an absolute owner. During the pendency of the suit , in the year 2006, Court had passed a status quo order regarding the suit schedule properties directing both the brothers not to alienate the suit property till the case is finally decided. Also, in 2011 just before the commencement of trial of the case, an Adverse Inference was drawn about the Will Deed allegedly executed by my grandfather in my Father 's name. The Will deed in my Father's name was not proved in the Court and hence was declared as Null and Void. So also the Will Deed and Gift Deed allegedly executed by my father in favour of my two brothers.. No sooner the adverse inference regarding the Will Deed of my grandfather was drawn,, both my brothers executed sale deeds to a stranger. And the property so purchased was hypothecated.The sale deeds are registered and enteries are made in the Revenue records. These purchasers were not impleaded in the partition suit,, and my brothers after having the sold the property during the trial , have lead their evidence and have produced the Will Deed of my Grandfather (Declared as Null and Void) , Will Deed and Gift Deed of my Father (Both declared as Null and Void) . My equal share amounting to 1/3rd is declared.
Apart form my share,since I have sentimental attachments to the property as regarding the rest of the property ,
I want to get the sale deeds addressed in the Court of law.
What remedy is available in law to get these Sale Deeds cancelled.
Alternatively what kind of suit can be brought up against these so called purchasers in order to meet ends of justice .

Kindly suggest .
