Ok, if he is lucid for periods of time, son could see if he could get father to sign a POA during one of those periods. Since he has not been declared legally incompetent by a court, he is still presumed to be competent even though he has dementia. I have had clients who had dementia and they would have periods of lucidity that would last minutes, hours, and even days before they slipped back. When I needed to discuss things, I would wait until one of the caregivers called and told me that they were having a "good day" to talk to them. It was close, but since we were only acting in their best interests, I made sure they understood as best I could.
.
The only other option would be for son to seek a formal guardianship through the probate court for father so he could take complete control over all his affairs.
