My sister is a hopeless drug addict, and my father has Alzheimer's or some kind of dementia, and she has been spending $3000 to $5000 a month on his credit card for years. He refuses to quit letting her spend all the money she wants. She is manipulating the ever-living hell out of him. She is even trying to get control of all of his money. My mother finally found out, and her and my other sister (who is a lawyer) are taking him to court to try to get him declared incompetent. The court date is in two months. One doctor has refused to sign the paperwork they would need. I am prepared to testify for my mom and lawyer-sister. I don't know what is going to happen. I haven't posted here in a while; I don't know what else to do.
