I today received the COP order appointing me as my mother's deputy. My mother has a number of different accounts with Halifax including a current account that she jointly holds with me. I assume my first step is to register the deputyship with Halifax? I can't find any information about registering a deputy order with the Halifax (there is information for a LPA). Does anyone have any experience of this? Any advice is gratefully received. Will I have to open a new deputy account with the Halifax? Or will the Halifax simply give me access to the existing accounts? Also will be able to have Internet access to the accounts?
