I am trying to help my partner get through the loss of her Father. In november 2009, her youngest sister (who was looking after their Father and charging him $7000 a month for the privilege!) managed to get him to sign a durable Financial Power of Attorney. In Late January 2010, he suffered a fractured hip and was admitted by the youngest sister to the Mayo clinic (she is a nurse and her husband is a Doctor of Osteopathy). On his admission paperwork, he was listed as having dementure ... he died 4 days later, and now the youngest sister is spending money like it is water, and claims that their Father died with no money. She is also resisting having the estate put into probate (he died intestate). We are sure she is rifling the estate (she is unemployed, but has 3 horses at an expensive stable, and has just bought a new car for her daughter) .. what should we do ???
