My dad, 80 has asked for help with my mom,82 who is suffering from dementia but not been officially diagnosed. She will not let anybody,including my dad attend a Drs appt. with her. She is physically in good health, not on a lot of medications but is slipping bad. They are living independently now and Dad wants and needs help. I am the oldest and living the nearest and have taken care of their needs when asked for a long time. When doing the POA can I do it for both parents on a single document? This is dads wish to simplify the process because then mom wont ask him a thousand times what is it that she signed.
