Can a person be declared incompetent with just a physician letter that is not documented in their chart or do you physically have to go to court to make it stick? Mom still works and takes care of herselft 75% of the time but my sister claims the POA cannot be revoked to remove her because she has a letter from mom's doctor?
As Fixer mentioned - it is best to talk to an Elder Care Physician to ensure all the correct steps are being taken. Perhaps there is an easier way to keep from having to go to the court. Take care.
