Hi sir, My father had given our flat in West Delhi to my mother's brothers in 1988 on good faith and without any rental agreement. They have never asked for any rent from them. My parents started asking them to vacate the flat 10 years back but they kept on making some excuse or another and finally now they have started claiming that the flat belongs to them. My parents have the ownership documents. Please advise if a legal case can be put on them and what are the chances that they can get the flat back.
