I have given GPA (done in Nellore, Andhra Pradesh) to my brother-in-law in 2003 when I was not aware of property laws and I believed him a lot at that time. He used this GPA to sell one of my property in 2003 as per my wish. It is a general power of attorney with "power to sell".
I do not have good relationship with my brother-in-law now. He cheated me 7 lakhs cash which I lent him as loan.
I have 3 other properties now in Nellore which I bought in 2004, 2007 and 2008. My questions are:
1. Can he mis-use that GPA to sell my other 3 properties which I bought in 2004, 2007 and 2008?
2. Is that GPA in 2003 void after that sale transaction in 2003 or is it valid forever and he can misuse it anytime against me?
