Relative is Not Vacating

Hi, I'm asking this Behalf of my Relative Aunty. Case: My Relative is not vacating the house, they are staying there for 28 Years. There is no Rental Agreement, also they are not paying any rent. Right now they are staying in 2 cents House, but they are claiming for total 10 Cents. Still, we didn't any order from Court from their side. But we got Notice from their Lawyer. History of my Aunty Prabha: Prabha's Mother had Two Husband, first one ran away, so she married for the Second Time. For 1st Husband 1 Daughter (She is right now staying along with her Husband in this Property and creating the Problem). Her Age is around 66. My Aunty Prabha is the only Child of the Second Husband. The Property was in the Name of the Second Husband(My Aunty's Father). Last year her mother Passed Away, after that Prabha Aunty immediately transfer the Property to her Husband Name. We have filed Case in Madras High Cout, this is our Lawyer Statement: The order is we can put Fench without Disturbing them, so that next time we can tell complete 10 Cent is in Our Control. But I think without Vacating them what is the point in Putting the Fench? Legally What can be done? Looking forward to your Answers. Thanks
