Re: This requirement for paper bills/statements...
ensure you are entitled to do what you are trying to do
This is the primary difference between the British legal system and a lot of the Continental ones (mostly derived from the Napoleonic Code).
In the British code, anything not specifically made illegal is legal.
In the Continental Code, unless something is specifically illegal, it can be deemed to be illegal.
Of course, our current government is trying very hard to change that..
