(my husbands stepfather) He has been diagnosed by four doctors with Dementia/ Alzheimer's. His kids talked him into divorcing his wife after 43 years of marriage. And took him to an attorney and had them made POA the day after he was diagnosed incognitive by a Psyciatrist. Three days after the divorce was final, they moved him out of an assisted living facility and into an apartment to live by himself. They haven't had anything much to do with him all of their lives except to ask for money and at Christmas. They said he had been doing really good lately. They just want his money. Those of us that are not in denial and have done our research on the disease know that it comes in waves, but can change at any moment. They told him he could walk across the street (four lanes of traffic) to go eat. What can we do to protect him?
He is still your husband's dad and your fil. Focus on him, not his biological children. Accept what you can't change and make the best of it.
You mention the bio children of the Step-Dad were able to get Power of Attorney with the father giving approval. That can happen as someone with memory issues can still have clear moments where they can understand a legal document.... it is up to the attorney to verify that Step-Dad knew what he was signing.
There was no mention of changing a Will. Was a new Will created? If not, I wouldn't be surprised if your husband's Mother is still in the Will, and especially after 43 years of marriage she would inherit everything.
That is so very wrong to move a person from Assisted Living into an apartment to fend on their own. Something needs to be done about that immediately. People with Alzheimer's/Dementia do NOT get better as you already know. You are correct, it can come in waves. Next thing the children will find that they would need to hire 24-hour care which is MORE expensive then living in Assisted Living.
So sad the father is being used as pawn in this situation.
And the joke's on his kids, in my opinion. They have volunteered to be responsible for him in the hope of future gain, but unless he dies suddenly he will likely outlive his savings.
