My grandmother (dad's mother) recently passed away. She had always had a will stating that her assets etc were to be divided between her three children equally. However, turns out my aunt had taken her to an estate planning lawyer and arranged for her to sign a new will a year before she died stating that she is leaving a much larger piece of the pie to her. My father and uncle are now wondering what they can do about contesting a will and have it declared invalid, because its likely she didn't know what she was signing because she is Italian and doesn't read English. Can anyone help?
