My 90 yr old dad has always had a will. He had me, as the oldest daughter, and another sister as administrators. Two other devious sisters went and forced him to change it. Its been 4 yrs now. These sisters have done things the rest of us have no knowledge of. I've been told their POA was obtained illegally. What can I do now? I'm afraid my dad's estate will be squandered away before he's even dead! What can I do, as the oldest sibling, and his first choice? Atty's are expensive. Is there a way I can gain control back before all of his things are gone?
