My father in law has stage 5 AD and went on vacation with his girlfriend and got married but didn't tell his family, only hers. My husband is POA and we just got a letter today that the address of the IRA has been changed. We called and he said he didn't make any changes but then a few hours later talking to the new wife she said they had to make changes. He then yells at us and said we are only after his money and he changed his trust and its none of our business. We just talked to an attorney last week about getting conservatorship and guardianship but all of this has now happened. We wanted an annulment but seems impossible in the state of Iowa. This is such a mess and we are very concerned for his health and well being. I feel for everyone else that has had to deal with this. His psychiatric evaluation 3 years ago came back that he was extremely low functioning. Surely we can get him declared incompetent. She refused to sign a post nup. She has isolated us and tells him we are after his money even though we have been POA for 2 years and never took a dime of his money. Almost every attorney has been telling us not much we can do. Anyone in here in state of Iowa and had success?
