My sister was appointed guardian over my mother after a catastrophic stroke, my brother and his family have moved in with mom and sis to help take care of mom. My sister is paying my brother to watch mom during the day while she works. My brother works nights. The rest of the siblings as well as the other grandchildren are not allowed contact with mom/grandma. Is this legal? My sister will not allow assistance from the nursing facilities in the area to check on mom. Mom qualifies for Medicaid assistance but sister will not do the paperwork. She insists that she and my brother can handle things on their own without outside interference. Is there anything that the rest of the family can do?
