My uncle and aunt is residing in a flat in chennai for the past 30 years. The owner promised to sell the flat to my uncle 10 years back, my unclee has done all the maintenance works amounting to Rs.15 lakhs related to the flat till date believing him..but due to increasing real estae prices, he changed his decision suddenly and he wants his flat back. My uncle told he cant vacate all of a sudden..He then brought some rowdies and threatened to vacate my uncle and aunt. My uncle has filed a complaint in police station FIR has been lodged against him. Now the police has filed a chargesheet on him. Now for the past few months the owner has closed his bank account to which my uncle was sending the rent. Even when my uncle sent the rent via money order it got returned. Now he has filed a case in the court asking for higher rent. Kindly let us know what is to be done. My uncle and aunt are confused.
