Two spouses on a deed, one passed away in april with no will

A close friend of the family that I am preparing some documents for to notarize is currently an owner of her mothers home since she passed 5 years ago. However, her and her husband were on the deed to the house, in which he passed away this past April. She is terminally ill and doesn't have much time. She is giving POA to her one daughter and trying to figure out how to sign the deed to the home to her daughter as well. Now in the State of Ohio, does she have to fill out a quit claim form and remove his name even though it was her home to begin with? Or is she able to sign the deed over to her daughter right now? Also, with her daughter being the POA (the same one whom she will be giving the ownership to the house to) would she be able to act as her POA to sign a quit claim if needed and what needs to happen with that form once it is completed? Thanks!
