Relative added my name in a legal case

Hi, I am a student living in USA and my uncle forcing us to sell our apartment to him. Our apartment is right next to his apartment and he is been taking care of it for us. 2 tenants has been living in this apartment( his friends) and he been collecting rents from them and not giving us since last 3 years, we live in different town. the apartment is in Delhi. It was our fault that we never forced him to pay the rent because he is very close family. This is what happened. Last year we needed some money and we asked him to help( 6 lacs). After a week we informed him and told him want to return the money so please share the account info. He said its ok you guys can return no rush. After a couple of weeks we asked again and he kept ignoring. Now its been over a year and we asked him to vacant the apartment and settle the pending rent amount. He got aggressive and said we need to pay him 12 lacs if we want the apartment and he wont pay the last 3 year rent. He also filed a case against me and my parents. in the case he mentioned that we took his money. He added my name so that he can force my family to give the apartment to him. Our lawyer is asking me to send him a power of attorney. I looked into getting one from here but the process is too complicated for a student. Please could you suggest what are my choices. Thanks
