My dad is being assessed for nursing home admittance after being admitted to the hospital for a bad fall. it was also discovered he was dehydrated and under nourished. It has become apparent that my 82 year old stepmother is now incapable of caring for my father who is getting more difficult as his dementia progresses. The hospital social worker is trying to get my father to sign for me to be his healthcare proxy during one of his more lucid moments, If that can be accomplished how would I sign him into a nursing care facility as his healthcare proxy and not be responsible for payment. He and my stepmother own a home outright and their only sources of income is social security which they rely on to pay for every day expenses. There are no other assets. My stepmother is completely uncooperative about helping with the medicaid application and will not give me the necessary financials to fill out what is needed. Please help as I will be talking to the hospital social worker on Monday. APS is also involved due to my stepmother's negligence in providing proper care for my father.
