Hi
I have had POA for my Mum for a couple of years now. Mum was confused with cash - was giving people huge tips, she had forgotten how to write a cheque, lost all ability and confidence to pay bills over the phone and when I got her cash from the ATM it was disappearing at an alarming rate. I was aware of a few worrying instances that Mum mentioned in passing. I was lucky because Mum was only too pleased to hand over the responsibility her finances.
As soon as I had the POA documentation, I made an appointment with her bank. It was very straightforward, very efficient and takes about 15 mins. I needed: Original POA docs, Mum's account details, knowledge of Mum's personal details (maiden name; DoB; etc) passport/driving licence and recent proof of my home address. They asked me what I needed/wanted to operate the account and I had to sign some papers and give a specimen signature. I declined the cheque book, and within a week I received a debit card which only has my name on it, but Mum's account numbers. It operates Mum's account and both Mum and I receive regular statements. Mum's debit card ceased to be valid at that point. I can set up BACS transfers and DDs on the account - I can operate it exactly as if it was one of my own accounts. I have online access, so regularly check the few incomings and outgoings.
Fast forward 2 years and CH fees have rapidly devoured the money Mum had in the bank savings account linked to her current checking account. Therefore, in the last 2 weeks I have had to use the POA again, to gain authority to access 2 other savings accounts that I helped Mum set up a few years ago when she downsized her home. One account was a bank savings account, the other a building society one. The procedure to set up POA on these was very similar, but the arrangements were slightly different. The building society now has me as the 'authorised person' and I access Mum's account through her original passbook. With the bank - and this is the odd one - because Mum only had a savings account with them, and I hold several accounts with them - I operate Mum's account but it is linked to all my accounts for admin purposes. It's still in her name, but is linked to me as attorney, so I use my own debit card and PIN to access her account for queries and transfers.
Apologies for the novel - but I thought my recent experience might be useful. The outcome is the same, but each differs slightly in operation.
