My father had a stroke. My ex husband who has a drug record has gained power of attorney and now owns half my dads house. I feel that my father isn't in good hands with him , I am now being told to stay away from my father. I am an only child so I am totally stressed and confused how this all happened. Can I reverse this power of attorney and if so how long will it take?..I was not prepared or forwarned for this.is that normal and is that legal for my ex to take half the house..my dad is in diapers..slurred speach and very hazzy memories..and has been robbed literally by my ex husbands aquaitances..isn't this soe kind of fraud..elderally something????.
