My sibling was trying to evict me from my parents home. I went and told my parent of this and he said "DONT MOVE" He didn't want his property to be sold. SO we revoked to POA "which he didn't remember giving to my sibling anyway. We went to court and the judge ruled in my favor. Stating my sibling didn't prove the new POA was now binding. Now I have gotten the police to go with me but he wont let me see my father. No phone calls, letters, etc Other family members seem to think its sad but they are no help....
But you have received really sound advice get a elder attorney, quickly.
Don't begin to understand the weird/nasty/behavior that I've endured, just except it as nothing you can do to change their minds, but you can make an impact on your parents safety & living conditions.
I was out of state & my sister cut off communication & refused to answer my email. I sent a registered letter that she had to sign & she received notification that I was coming to see mom & implied that authorities would be called, long story short, she "let" me see mom, but it just got weirder as time went on.
My mom died alone & I feel really bad about that but there is only so much you can do & only so much you can take responsibility for.
Good luck in your struggle, try not get down in the dirt with the siblings, your parent is proud of you, remember those things & hopefully it will help you thought this difficult time
Does your parent have dementia or can he speak to make any decisions for himself? While your parent was in nursing home did you have regular contact with him?
