Legal right to ask for someone bank records UK
You might want to head on over to https://law.stackexchange.com/ and ask the same question.   However from a personal finance perspective this kind of drama is somewhat common when someone is deceased and financial expectations are not met by the heirs.  It sounds like the daughter was expecting a lot more in inheritance than was actually received.  There was probably an overestimation of dad's net worth and an underestimation of the cost of his care toward the end of his life. Its best not to participate in this drama, and I feel that you are correct that the daughter does not have a right to see the bank account statements prior to dad's passage.  The question is also if she has a right to see it now. Here in the US a joint account can be setup so the ownership transfers to other account holder(s) up death of an owner.  So in this case your mother would own the account.  If the account is setup as such, then the estate has no right to that money.  You may want to check with the bank for some free advice.  What is the classification of the account now that dad has passed?  When a person grants someone else the power of attorney they have the ability to act as if they were that person.  Most of the time POAs are limited in scope so If I give a person the POA to register a car in my name, they cannot apply for a credit card in my name (legally).  In this case, however, the POA was probably general so pretty much your mom could do whatever she pleased. So if your mom took good care of the dad and bought herself some nice jewelry that is perfectly allowable with a general POA. I strongly doubt this daughter has any rights to the past records and may not even have the rights to the joint bank account currently.
