A friend of mine deceased leaving five legal heirs and some properties. In a family resolution all legal heirs appointed one of their relative as POA and the same isregistered to dispose a property. I introduced one of my friend to buy the proerpty and sale agreement is entered and all payments made and the sale deed is executed by POA and yet to be registered. In the meanwhile one of Principals(legal heirs) passed away. is the sale deed executed by POA is still legally valid? or what is the solution to this problem?
