Mother made will for property which was paid by me

There is a house in joint name of my mother & grandmother which was built entirely using my money that I sent from abroad. House has 2 bedrooms one of which I kept locked with my belongings & I am living in another city. Both my mother & grandmother died but knowing the bad intentions of my brother they left a Registered will solely in my name along with possession deed ( Kabja Rasid ). Now my brother has broken into my room & taken possession of it. What can I do to first to evict him from my room while I execute the will & transfer house in my name which will take time. I am Hindu.
