My sister and I could be co-guardians (if possible for 2 to be guardian) of our elderly (89 yrs old) father with dementia and other medical issues, there would be no dispute between us as far as one or both of us being guardians and we would have medical documentation on his physical and mental state. Neither one of us has the "funds" to spend for an attorney we feel based on his condition etc. we could do this ourselves if there are papers we could submit to the courts ourselves.
What would guardianship do that would be different from what a POA does?
Is it the situation in which Dad is fighting everything that you do or suggest?
