Hi Eve Kate
I completed POA with my solicitor and, like you are being requested to sign, it includes the power to open accounts sign for utilities and several other general powers. I was given the option to delete any powers that I did not wish to be included. I assume that if you discuss it with your solicitor you can exclude anything that you don't like.
In my case I was happy to leave all the powers in place as I wanted to cover all eventualities that prevent me having to make an unwanted trip out there. The POA includes provision that the solicitor must act only within your interests.
Hope this helps.
Dave
