House not vacated even after court notice issued

Dear Sir, We are two brothers. We both are married and I stay with my family in Hyderabad and my brother's family stays in Karimnagar (a district in Telangana). My father owns a house in Karimnagar where my parents and my brother's family used to stay since 2001. My parents were subjected to mental harassment by my brother's family since their marriage. They forced them to leave the house and occupied the entire house for themselves. Presently my parents stay at my grand father house. My parents approached court and issued a house vacation notice in a period of 3 months. But 3 months passed, they still didn't vacate the house. My father went to the court again but they said their job is done with issuing notice. They also told to complain to police and make them go out of the house. My parents at this old age are getting weaker mentally and unable to understand what else they can do to get back their house. (I tried to convince and counsel my brother's family, but legally I don't have any rights so my hands are tied) I request you to please help us in this issue and provide with a permanent resolution. Thank you, G Shiva Santosh Kumar
