As far as what i understood from different posts is
If accused is outside india,
-> No lawyer can represent them, because one can not sign on vakalat.
-> Just by signing on vakalat and sending the document to india is not accepted <as per known advocate>
-> The above statement can be challenged in case, one can get it done infront of officer in Indian Embassy.
-> To deal with future proceedings, one might need signatures of accused, its better to have POA transferred to some relatives.
Please correct me if i am wrong and also let me know if there is a way to deal with all these things without going through lot of hiccups as mentioned above.
