This thread is clear indication that a lot of seniors aren't aware of their rights and how to protect them.
Explanations of senior rights are available online, and the documents you need to protect your assets and your right to chose where you live are free. You should get them notarized - in fact, some of those documents are null if they aren't notarized.
Some banks will discuss how to protect all your accounts, and some will keep copies of all the relative documents. Your doctor can help, too, and they have documents.
