Quit Claim Deed

My parents are separated (not legally) and live in different states. It was not an amicable separation. My mother's home in GA has no mortgage or liens. My father (age 85) is trying to pressure my mother (age 75) to sign a quitclaim deed because he says he wants to be sure that I don't inherit my mother's home but insists that he would not register the deed until after my mother's death (assuming she predeceases him). I have no interest in my mother's home but am concerned that my father might indeed register the quitclaim deed immediately upon receiving it from my mother and would demand to take possession of the property My mother could then be forced out of her home. I want to ensure that my mother keeps her home and have begged her to see a family law attorney for advice. If she does sign a quitclaim deed, is there a way to include language that would prevent my father from registering the deed until after her death?
