My sister and her family moved in with my mom, and now they're spending all her retirement money.

This daughter can contact her Mothers doctor or the one with the medical power of attorney and have a medical assessment which includes mental capacity to make decisions that provide care for them. I am sure the doctor can render her legally incompitent to make legal and financial decisions for herself ESPECIALLY since the bank has been called. I would call APS, Adult Protective Services and file a report that your Mother is being abused verbally if they are trying to extort her as you can be fined for extortion of the elderly. These daughters remaining care and it is going to take an IMMEDIATE decision and they have options to halt this now. The Mother needs to be REMOVED from this situation and it is not healthy and then once removed, have a plan to get everything back and it might be selling her home so the sister cannot live there and have the Mom in a nice assisted living or keep her home and have her get paying roomate to help her . This woman has been exhorted and clinically depresssed and there is concern for her safety. This woman would be protected by APS because her family is exploited her.

there are laws that help the elderly in this regards. You need to contact an attorney!!!

Does your mother realize what's going on?Regardless,take action immediately!Tell those people they have a week to get out of there or you will have the police over.At the same time name yourself as your mother's guardian/representative/power of attorney.You can get the forms,have your mother sign if she can,then it will be legal,then you can start managing your mother's affairs.If she can't take care of herself either move in with her or get her somr home healthcare.But please don't feel guilty about kicking those people out.They certainly don't care about your mother and they will bleed her dry if something isn't done soon.Make the love you have for your mother stronger than the guilt you might feel getting rid of them.I had it happen to me and when the money is gone then they expect you to come up with more no matter what you have to sacrifice.I was left penniless hungry with no help.Don't let this happen to your mom.

The best you can hope for is that your mom won't pass a competency hearing -- and you get named her guardian, then you can send parasite sis and her entourage down the road yourself, and protect your mom in the future. There comes a time when our parents are not longer logical or able to make good decisions, and that's the hardest thing -- when you have to step up and tell them that and take that ability away legally, then do what you know is right for them even if they hate you afterward. Just remind yourself that once in heaven the mind will clear again and they'll truely be able to understand your actions and motives, and will know you acted out of love for them. I also suggest that in the meantime, you also move in with your mom and become a major thorn in the side of your sister and her family -- make their life miserable enough in that house and they may move on anyway; don't let them relax or sleep or get anything without a hassle -- time to go to war!!

My sister and I are experiencing this same scenario with another sibling and I found this article extremely helpful.
