Help ! Trying To Fight For My Lifes Memories

My sister,brother and myself are beneficiaries of our mothers Will.  My mothers attorney is executor of the estate, which is to be divided 3 ways. both parents died of cancer.  Dad  passed 2009 . Mom made sure dad passed first.  Mom passed 2010.  before mom's death she was planning to change her Will.  Her younger sister Joan my niece Angela went with her to try to change her Will. Is there a law out there, when individuals have cancer and under medication. that protects the original Will or stops individuals from influencing manipulating mom to change the original Will.
