Hi there. 

I'm assuming that you are asking about All India Bar Examination. (AIBE)

A simple google search will provide you the question papers of previous years. Other than that, there are a lot of books in market that can be founded easily. (Check arihant Publications). Also, you can ask your Seniors to arrange the previous years papers for you. 

Check the link below for referring to some sample papers:
