Brother and Sister Property

whether the open site behind the back of your uncles's house is in the name of your mother, if not she can go parition and seperate possession suit.

Thanks for the rep;y sir,

I like to inform you that the land is not in the name of my mother or my uncle (mothers brother) it is still in the name of grandparents I think. This place was not purchased or developed by my uncle. My uncle wa living in hut only. Their childrens only constructed the house in one part. Backside portion they left vacant. 

I like to know that my uncle should mandatory give the property in written instead of oral communication. In which court we can file a suit and in which way.
