I had to do it for my Great Aunt who had Alzheimer's and whose husband had had a permanently debilitating stroke. She was 84 years old, and we also had to seek and obtain guardianship. It's really no use to have conservatorship if you she can make contracts. The guardianship prevents her from being legally able to sign a contract
Who is ex ms. emo and how old is she? If she's happy with it will be easy peasy. If she objects, or worse yet someone convinces her to object, plan on spending a wad of money getting it done. If you're lucky, she understands that she is losing control and trusts you and her doctor to tell her it is time. My good friend's husband was diagnosis'd with early onset Alzheimers in his late 40's, and his neurologist told him and her that he needed to sign all decision making powers & the money over to her right then because he was going to hate her by the time she needed to make major decisions about money by herself, and he would end up penniless on the street. It's the only situation I've even known where when the time came and he was furious with her for deciding to sell this or that asset so that they could keep their heads above water.
Every other time it's been a battle of the lawyers, and it takes about 3 months if they contest it. There will be an investigation ordered by the judge to be completed by someone from your county or state to ensure that it's the right thing to do in your situation, and there will be more doctors reports. Not at all cheap or easy.
