I have POA over my parent's health care. My sister, however, is involved in speaking to the nursing home and obtaining information regarding our parent's health care. She has also been given and kept documents by the hospital and nursing home that should be in my hands. The problem is that my sister does not respect my opinion or my legal authority over our mother's health care. I do not want to call attention to this problem at the NH however I do not appreciate it when the nursing home calls her and not me to give information regarding health issues and I am concerned that my sister may be giving health care recomednations without conculting me. Could someone clarify my rights and the rights of my sibling on these issues? Thanks.
