I brought a property at Hyderabad which was advertised in the local newspaer for Sale, from the link documents it was self owned , after bringing the property before we could move in, my dad passed away. We kept the door and gate locked and were out for performing last rites to dad, meanwhile seeing us not there at the property, the Vendor's Son and Wife broke open the locks and with the help of the local goons(Calling BJP leaders) whom their advocate (BJP spokesperson) has arranged have occupied the property. There seems to have been a family dispute which was not conveyed to us while purchasing the property, now vendor's wife has filed a partition suit stating that the property was brought with the land sold at some other place that was in her name which is totally baseless.
When we went to file for the trespassing with the local police station, even they are not helping calling it as civil case.
How and whom should I approach to take possession?
