I always wonder how things would be reconciled if something similar happened to a bank. What would be the simplest way to ‘download’ one’s balance whilst proving that the downloaded files were signed by the bank?
Your best chance would probably be mailed statements
Your balance is at a bank. If the bank is gone your balance at it doesn't matter.
I'm good with starting from 0 if the bank is (my mortgage is a lot bigger than my balance)
