So their legal department will tell them to give you a copy of the document.
The reason why is that as executor you are essentially standing in the shoes of your father and can do all he could do when living. When living he was entitled to a copy of that document.
Otherwise you will need to apply to the court for an order.
I find all of this a bit strange because what happens normally is that a minor has to have a trustee designated and then when the child reaches the age of majority this is changed.
As well, it seems odd that in all these years your father never turned his mind to this and also that the bank never asked him to renew the designation.
It is also unusual that the bank statements would have this error.
So the bank may have to be compelled to do another and more thorough search to ensure that there has not been a more recent designation.
It is also simply disgusting and unethical for your sibling to be acting this way but you don't need me to tell you that. Money has a terrible way of making some people show their true colours.
If the bank refuses to provide the document you will need your own lawyer unfortunately.
Does this help as a starting point?
