96yo Mother with dementia has been emotionally manipulated to not speak to any of her family with the exception of my late brothers wife. Reason being, us family members who were executors, recently tried to monitor her accounts, as precaution with how close the caregiver has gotten. Once caregiver got wind of this, she convinced my mother to remove my sister and I as co-executors and now has my late brothers wife (a friend of the caregiver) listed as the new executor. The caregiver, my mother and my ex sister in law have convinced my poor mother that we are the enemy because we want to fire the suspicious caregiver. Our calls and mail go unanswered and we have all been told (bullied) that if we try to remove the caregiver (per our mom supposedly), the rest of us will certainly be removed from her will entirely. We are all well off on our own and aren't looking to gain too exuberantly from mom's future passing, but find it very suspicious that we have been labeled the enemy by her in home caregiver, which is way out of character and we are worried. Although we don't want to risk getting cut out entirely and now having been removed entirely from the executor process (done with her attorney while we were out of town....no coincidence), I fear for my mother believing and loving so much in her caregiver- more than us, that in essence she doesn't even remember when or why she even changed the executor and will in the 1st place due to dementia. My fear is that the caregiver has brainwashed our mother into giving her everything, instead of her own family, who loves and misses her very much. But we are denied and shunned every time we want to visit or call. It's literally scary how quick this all happened within 2 months. Looking for help on how to handle this.
