A relative is Executor of her Mother's Will. As part of the general trawling with institutions, it appears that the deceased's husband has two dormant accounts with Ulster Bank, the balances of which are not known. Executor says that she has written to UB, but they have not responded. Is there any timeline whereby banks must respond to queries? I know that if one makes a 'complaint' to an insurance company, there are very strict timelines. Just wondering if Banks have any??
