Is it possible to file a atrociti act against the owner and developer in police station as we cum in that caste Schedule tribe.and wat case should be filed in court.
If owner is claiming the property, he should prove his title.
You have said that the owner's father had taken money 40 years ago but whether he had made any agreement to sell this property to you, even if it was an unregistered document?, if yes, then with the help of such document, you may first file a suit for permanent injunction and also for specific performance of contract against the legal heirs of the original vendor.
Let them give a reply through court and you may also obtain a temporary injunction restraining them from not to vacate you till the disposal of the main suit.
If their illegal actions are beyond tolerance, you may file a criminal complaint also simultaneously stating that since you have filed a case they are troubling you.
Dont vacate the property till the court passes an order.
