Secondly if you have more than one EPOA, think carefully about whether you wil make them jointly or severally. If they are jointly, everything needs to be done together.

This is a really good point. My dad and I were both POA  for my grandfather but by the time I needed to start acting for him my dad already had advanced alzheimers and couldnt have done it. Luckily we were appointed severally.

Polks a solicitor wouldnt have done all that leg work that you have done, it would have been the job of the POA. Its all the stuff I've had to do myself over the last couple of years. So you have definitely saved your POA/executor a hell of a lot of work and headaches when the time comes.
