Can I charge rent and sitter services by family if pt has dementia and unable to sign family care giver agreement

Because signing as your mother's agent to pay you personally would be a conflict of interest and self-dealing, the family caregiver agreement should be signed by the alternate or substitute agent.  Keep a detailed log and receipts.  Arrange for payroll withholding.  Make sure all your siblings are on board and that no one is likely to accuse you of exploitation now or when they receive less than anticipated under the Will.  Consult an elder law attorney to make sure that all of this is done in a way which prevents North Carolina Medicaid from treating the payments as "gifts" which would disqualify your mother for Medicaid.  You can use the Find a Lawyer function on the website of the National Academy of Elder Law Attorneys (www.naela.org)
