My dad’s wife of 41 years filed for divorce in California a couple of years ago. She left the state when he had a major surgery 7 months ago and it was then that he made me his DPOA because he said he couldn’t do his bills or paperwork or drive anymore. He’s physically much better now that I helped him get into a memory care facility and the happiest I’ve seen him in years. However, his mind is steadily declining. Will I need more than DPOA to help him finalize their divorce?
