If you own the home as joint tenants with right of survivorship, then if anything happens to one of you, the survivor will become the sole owner automatically, without the home even going through probate.Note that the above refers to the title of the home, not the mortgage: signing or cosigning a mortgage does not directly affect home ownership (though typically it is the owners who are on the mortgage). If the home is titled only in her name, it is her home already, even if you cosigned the mortgage; if titled only in your name, it is your home. In that latter case, make sure you will the home to her.
