After reading this thread I find myself amazed things went so well for me! I ambled into my local RBS branch with the original PoA document I set up and had registered for my mother in 2008 (when I worked as a legal secretary) and they processed it right there and then, the only ID I needed was my debit card (but we both use the same small village branch of the bank so we’re both well known by the staff), they photocopied the PoA and handed me the original back and they’ve just added my mother’s accounts to my existing phone/tablet app and internet banking log-in, so if I log into my account, hers turn up as well.
Tbh, I’ve been doing her online banking for the past couple of years now, just with her leaning over my shoulder telling me what she wants doing and it’s as well I remember her log in details because she hasn’t for months!
I emember from my legal secretary days that banks always want to see the page with the red seal on it, to show it’s the original copy sent back by the Office of the Public Guardian - and I’m extremely glad I got both my parents to set them up and get their GP to sign them while they were both still healthy and had full capacity!
It’s time I set mine up, just in case.
