My dad passed away last January. When we got the will read, we learned that there had been many changes to the will that benefited his last girlfriend. We also found out that the lawyer he used was recommended by her. Whenever we ask questions about this latest will, they get very defensive. Could these lawyers have allowed her to sit in on these meetings with my dad? It seems like she had a lot of influence on him. Is there are law against that or is it totally legal?
