My husband is POA over his mother (97) who has dementia/Alzheimer's. 24/7 care is provided for her in her own home. This was her wish. She has a 90 yr. old sister that comes to visit her several times weekly and is causing problems. She dislikes one of our caregivers and treats her horribly.. Now, the caregiver is being accused of abuse, although nothing has been witnessed. We know this is not true, but the sister is very difficult and has always been a trouble maker. I called in the head of an agency that has over 100 caregivers. The owner came to the home and evaluated the home, the caregiver, my mother in law, etc. She spent over 2 hours. I have written confirmation that my mother in laws home, her care and her health and happiness are perfect. Now, I am afraid that the sister will call the police or some agency to yell "abuse" because she will be upset with the findings of the agency that evaluated the situation. Should my husband also try to get guardianship so we do not have to deal with his Aunt?
