I've completed the forms for financial power of attorney - registered it online, printed off the registration form and am going to post it off tomorrow. My question is - when that is done (apparently the forms have to be officially stamped) does that mean I have power of attorney immediately if my mother is agreeable? And so how does that work in terms of -say - telling a bank so I can look after her account? Are there any restrictions on what I can and can't do? For example,my mother has willingly given up her bank card for me to withdraw her money from a cash machine as it's convenient for her. I read somewhere that if you have power of attorney you can't take money out of a cash machine with their bank card ? Thanks for any advice.
