My grandmother lives with me, but I do not have POA and I have no paperwork of any kind. I'd like to know what legal and medical documents I should have in case something happens. I know she is DNR, but I have no paperwork for that. I also do not have any health proxies or whatever that is. I'm not sure what that's for, I just keep hearing about it. So what should I get and how do I go about getting it? Thanks.
