Injunction on property

My grandfather left a will which was not registered in which he divided his house to his 4 sons. My uncle inserted a few clause with arrows and took possession of the ancestral home in which he lived for 10 years that is till 1998. He made a gift deed of it to his wife in the meanwhile and through bribe got eb and water connection etc. His wife sold the same unpartitioned house. We where in Delhi at that time and when somehow we got to know of it my father questioned my uncle. He left the house. Till now we have been residing in that property. The property is to be divided into 2 portions which as per the will does not go to my uncle. Already the matter is in civil court for partitioning of property. Now my uncle after 20 years has sought for injuction of our home. He has already criminal cases against him. Please guide as to the course of action to be taken. When we applied for EB and water connection the municipal authorities said that since property is in dispute they will not give receipts.
