I am not sure. It is an uncommon occurrence for people not related to you by blood or marriage to give out huge amount of money, because, they love you like a son.Thank you for replying Sir.
I understand that money gifted by non blood relative is taxable.
But with a valid and strong gift deed, will it be acceptable.
Another way could be, have the old couple gift the money to a relative by blood/marriage, and then, have the relative by blood/marriage gift the money to me. Bank statements of the donor is not required.
