My grandfather got remarried 15 years ago. Needless to say long story short his new family and his old did not mesh. My grandfather passed about a week ago. They read the will, but did not contact my mother. We found out from my cousin. My grandfather left all property to my mom, my aunt, and his second wife. She states he put her name on the deed a few years ago, and that since her name is on the deed it trumps the will. Is this correct?
