Possession

Police complaint, eviction notice....................

Has the WILL been submitted to authority under whose jurisdiction property falls and house mutated in your name?

Do you have copy of WILL and death certificate?

Better approach avery able counsel specializing in revenue/property/civil matters and proced further under expert advise of your counsel.

You can approach the District/Taluka Legal Services Authority and try to settle the matter thorugh the Lok Adalat. If not successful, a regular civil suit may have to be filed.
