I am caring for my father, who has Parkinson's and Lewy Body Dementia. My husband and I moved our family in with him 2 1/2 years ago. I have medical power of attorney and my dad indicated (in writing) he would like my brother to serve as guardian. My husband and I have been working on a care agreement to begin compensating us for Dad's increasing, but still manageable care. My brother is now considering taking Dad out of his home and putting him in assisted living rather than pay us. Dad has always said he did not want to live in a facility, and we are still fine caring for him at home. Dad's Advance Health Care Directive clearly states that I have the authority to admit Dad to a licensed health care facility. Does the role of guardian trump the role of health care power of attorney?
