My advice would be to get a lawyer and have a judge rule that she had no choice. I was afraid of having to do that with my mom**, but she didn't put up much of a fight. I was surprised. I think a judge ruling that she can't decide for herself is the only legal solution.
**I had at least one person volunteering to testify that Mom couldn't make decisions for herself.
