Share of property for a daughter under Muslim Law

Mr X had one son (Y) and one daughter (Z). I am the son of the daughter. After X died, my uncle, i.e. Mr Y owned 2/3rd of the properties and gave my mother 1/3 share. It was done through gift settlement deed. (Later, my mother gave it to me under settlement deed.) On the face of it, it looks fine according to Islamic law. But the proplem is — My uncle kept all the property which are of high value - i.e. property lying adjacent to the road. (Land value is around 15 lakhs per cent - i.e. 435 sq feet) He gave my mother the land which lies behind his property. There is only 6 ft wide pathway to access our property. That 6 feet pathway is also registered as 3 ft for each, to be used by both. (He kept another high value property which also lies adjacent to the road.) Since, the pathway is very narrow, our property has very less value - 5 lakhs per cent. Only two-wheelers can go through it. So, even though the property lies in very good area, no one comes forward to buy it. It seems that he has deliberatedly planned so that we cannot use that property or benefit from it. Is it not cheating? Can I sue him for keeping high value property with him and giving us low value property? Please guide me what I can do.
