I live in Michigan an in 1997 my father died upon his death he had my sister and I added on to the deed of my parents house,my mother now wants us to sign off the deed, which is ok her and my father owned the home not us kids,so my question is because I am married does my wife have to sign off her rights to the house,we are not selling just signing off my mothers name is on the deed as well,she will now just be the sole owner of the estate.
