My father had only 3 more days to complete his rehab, but my brother went against the rest of the family's wishes and agreed to let my father sign himself out of rehab and took him home. My brother has been living under my father's roof and main objective to doing this was so he wouldn't be placed permanently in a nursing home because then he'd have no home himself. My brother is not stable and the family fears for my father's well being. The rehab center was well aware of the concerns family had about having father going back home to live with his son. The rehab center said father was of sound mind to make the decision to sign himself out. My brother is somewhat dangerous and family does not want to have to go to the house, but now worried about how well the father will be cared for now. Is my brother solely responsible now?
