Contest on 2 properties

There is a situation where there is an ances’tral immovable property A from father side an’cestors and another immovable property B from Mother’s side(gift deed from her father). Father passed away in 1984 and mother passed away in 2011. In 1998 Feb, all the heirs of the Property provided GPA to the wife of one of the heir to execute release deed to her husband who is one of the heirs for the property A only. The GPA was executed in 1998 Feb and not registered. The release deed was executed by the wife of the heir in April 1998 and was registered in sub-register office. Property B was in the name of the mother. Shares of the Property A has already been released. Shares of the property B has not been partitioned nor released. Under these circumstances, if there is an appeal for contest in civil court for partition of both properties A and B, does both properties gets partitioned and registered release deed gets void ? I appreciate your responses to this question.
