To remove the Principle from temporay living arangements of another family members home which has no POA what so ever, to hold the Principle whom suffers from Alzhiemers and the family member is pretty much stilling money from the Principle saying the principle whom is not in the right frame of mind okayed and signed 2 of her personal checks and without consent from the Agent who has DPOA of the Principle. The Police department told Agent that the DPOA that we had notarized was not legal and had to be filed in a court of law. Is this true in the state of California. Please advise. So we can take further legal actions and prosecute other family member who has no POA at all.
