Complete process of Legal registration of land

you can file a partition suit

My honourable friend Vishnu is absolutely right.
In addition to this you will need to file an permanent injunction to stop anybody selling the land. This will stop any other party to sell the land until the matter is settled. I hope this helps.

In short you need to file for a petition of the land and a permanent injunction.

Whether your uncle has inherited or self-acquired the property left behind by your grandfather i.e., by way of any gift / sale or through any other document such as will etc. ??

What is the reason stated by your uncle to deny right of your father in their father's (your grand father's) property ?

 

 

Contact a local advocate, show all documents, revenue records and past history of possession and enjoyment etc., and first issue a notice seeking partition of the property.  Let him come out with his version and involve local relatives/friends for an amicable settlement.  Finally go for litigation as a last resort.

What is the reason for your uncle to take such a stand? Had the grndfather made a Will or executed a gift or any other conveyance deed in his favour? If not, your father (together with the mother, if alive, and the children, sisters included) have a share in the property. In fact, such intestate property is jointly vested with them. If so, your father need to file  a suit for execution. All the procedures would be taken care by the court's procedure. However, the matter may take years to be completed.
