My elderly sister is in care home on hospice care. My intention was to bring her home so she could be with family as her time drew near. My sister's estranged daughter who she hasn't spoken with in years showed up with a medical power of attorney that listed her in charge. She told the care home to stop her mother's pain meds and to allow no visitors. The care home said my name is also on the document but that per the daughters instructions I am not allowed to see the document. I am pretty sure the document is forged, which I will immediately know if only I could see the document. Do I need to hire an attorney to get a look at the document? Please help!
