They told me after the fact only when I asked what my sister was having my mom sign. She didn’t answer at first. When I brought it up to another sister, she said they were having it put in all 5 of our names in the event she passed to avoid probate, but I don't know why I was never included and wonder if they can do this without my knowledge? They have also been keeping her away from the house by having her go to different sibling’s homes and not letting me know. Is this legal or just some way to get me out of the house? I truly think it's great that 2 of the siblings are finally stepping up. One lives 2 miles away and almost 7 yrs has never taken her overnight. They are just being very secretive. It's just not right as I have been there for mom when they haven't wanted to or couldn't be. Now seems to be all about the money.
This is likely elder fraud.
You may want to consider contacting APS about this as well and ask that they investigate, telling them that your sisters forced your mother to sign legal documents she did not understand. Ask them to open a case to investigate.
