How to revoke POA?

Redhawk, if getting to an attorney is too difficult or expense you can create a new PoA by going to Legalzoom.com or Rocketlawyer.com and paying a nominal fee (like $40) to download PoA paperwork that is specific to the laws in your state. You will still need to have it notarized and witnessed. This is what I have for myself, and my mom. I compared ours to PoA paperwork I have for my aunt and it is basically the same (except they are in different states). An attorney will have the notary and witnesses already there (and you'd obviously need to bring the new PoA with you). FYI you do not have to tell your sister she is being retired if she won't remember it anyway. May I suggest whoever you assign should be younger than you by at least 15 years and hopefully local. If you can't find someone personally you can consider having a professional PoA (like an attorney) who may charge a fee but I'm not sure. I wish you success in finding the right person and making the change.

In my area there are no "elder lawyers" as such. Any lawyer should be able to revolk and reassign a POA. If you can, go back to the lawyer who drew the POA up.

Redhawk, all you need to do is have an Attorney [preferably an Elder Law Attorney] draw up a new Power of Attorney. The new Attorney will notify your sister that the old POA is no longer valid.
