ohh sweetie i feel for you and yes of course i will keep you and your sister and your whole family in my thoughts and prayers and i will pass it on to my church.
i feel so sorry for this all and yes try to get power of attorney that way you can in a sense take over the affairs of hers and then if he has no legal ties to the property such as name on deed or mortgage etc car he has no right to them and in fact he has no right to them now if he does not have his name on any of it and if he refuses than you can say hes stealing and hes breaking and entering into a property of your sister now for one but of both of you if you take power of attorney
and girl as hard as it all may seem GOD never made everyhting easy and i was always told that we can make it through and the tougher the situation the more thankful and the tougher you are when you get out of it
i know you can do this and you can always depend on any of us to help you out
just let me know if i was closer to you i would march up there with you and throw his butt out
oh that made my day to think i could do that
but stay strong and yes we will pray for your whole family
