My 92 year old grandmother recently went to her lawyer to update her will. She said she wanted everything divided five-ways between her grandchildren and is upset now because she feels her lawyer "bullied" her into dividing everything two-ways between her children instead. She now wants to make a new will which gives everything evenly to her grandchildren again. Do I have to go back to a lawyer (and pay another $500 odd) to get this done, or can I just buy a Will Kit from the post office?
