If your father is currently incompetent he can't complete a new power of attorney. You would have to apply for a guardianship through the legal system, and depending on whether he has assets, the court can name someone. You need to discuss his situation with an elder care lawyer, especially if he doesn't have assets, or if he is in a nursing home. Some states require support of a parent by a child/children.
