Land dispute

Is there any doucment regarding the parition and due to the partition your father got his share?  If your father has got the document of partition then file a suit for declaration and injunction, otherwise also you can file the same case on the ground that there was partition since the partition your father is in the possession of the properties which he got and that partition is acted upon.  To prove the partition you can lead the evidence of the elderly person of the village

Yes sir there is some documents regarding that.

Actually land was on the name of my father cousin brother.My grand father and and his brother (my grand father brother) took land from him half half and paid the amount for that but didn't do registry.
So piece of land which my grand father bought my father became sole owner of that land and he constructed house over there and we are staying there almost last 25-30 years.
Recently my grand father brother did registry of whole land on his name but they are not claiming that land belong to him. But may be in future after my father they will claim like that because we don't always stay in our village.
Yes my father has some documents regarding that land.
Please let me know how complicated this case will be? We are approaching to lawyer now.
