Situation is that my parents and recently myself have been taking care of my Dad's mum who is abusive in nature - has been her whole life? It has been detrimental to my parents general well being. Dad is currently going through chemo and mum has several health conditions. Due to what Dad is going through, I have temporary placed her in a care home, although i know she has been kicking up a fuss. It may be a possibility she returns to our home and I would like to know if there is anyway I legally prevent this?
