My fiancé's father is in an assisted living facility. My fiancé is an only child and has medical and financial POA. The assisted living facility has been slowly changing things so that they are the primary contact and we are concerned that they are headed to having the POA changed to them. Is there anything we can do to stop this?
This sounds more like a misunderstanding then a change. I can't see why such a facility would need to be the "primary contact", contact by whom??? Now I can see the facility making a change that each resident has only one primary contact if the facility needs to call the family. Otherwise, some families would want all the relatives including 3rd cousins once removed to be the call list.
If the above isn't the case and there is something else legal going on, then I would highly recommend to make an appointment with an "Elder Law Attorney" to get advice.
I'm puzzled as to how they're doing this, apparently without authorization.
Has your fiancé or his father raised this issue with any of the admins at the AL facility?
No, they can't change a POA unless they take Dad to a lawyer and have the first one revoked. Dad has to be able to understand what is going on.
Hopefully you have his DPOA on file at the AL.
