My Grand Father inherited 21 Acres of Land from his father.He devided that land in 3 parts , 5 acres for my Father,7 acre for himself and acre for My Uncle.He did this uneven distribution because he gave some land to my father for building the house and wanted to compensate that for my uncle.After demise of my Grand Father in 2011 ,My uncle is keeping and selling from the 7 Acrea of My Grand Father's Land.As my Grand Mother is staying with him and very biased .Since it seems very unjustice to me that land is devided in 5 Acre and 16 Acre.Can i raise objection to this.Please advise me.Do i have claim on this property ?
