I have POA for my sister who can not read or write and really don't know the meaning of things. She has been dating this man who has been married 3x and divorced for being mean towards other women but my sister will not listen. His own brother disagree with them getting married as well as my own family do I have the right as POA to stop this from happening
As your sister may be debilitated enough to require guardianship it is time for you now to see an Attorney for legal advice. We cannot know her, you, or what is happening with her medical, mental condition.
I surely do wish you the best. This has to be terribly distressing. I am glad your Sis has someone on BOTH sides here concerned for well-being.
Guardianship, she again has to be mentally challenged or have Dementia.
